Peraturan Menteri Kelautan Perikanan RI nomor 1 Tahun 2015 menetapkan ukuran lebar karapas untuk Kepiting Bakau (Scylla serrata) layak tangkap minimal 15 cm. Konstruksi trap yang digunakan untuk menangkap Scylla serrata di perairan Rembang memberikan peluang tertangkapnya stadia juvenille (< 10 cm CW). Trap dengan inovasi celah pelolosan diasumsikan dapat meloloskan Scylla serrata stadia juvenille. Desain celah pelolosan berbentuk segi empat terletak sepanjang bagian sisi bawah trap dengan ukuran tinggi 3 cm, memberikan hasil tangkapan Scylla serrata yang terkecil berukuran lebar karapas rata-rata 8,3 cm dibandingkan tanpa celah pelolosan dengan ukuran terkecil lebar karapas rata-rata 5,3 cm. Tertangkapnya Scylla serrata dengan desain trap bercelah pelolosan < 10 cm CW (stadia juvenille) mengindikasikan bahwa populasi biota tersebut di perairan Rembang berukuran kecil pada saat dilakukannya penelitian pada bulan April sampai dengan Juni 2016. Regulation of the Minister of Marine and Fisheries of the Republic of Indonesia No. 1 / 2015 set the legal size of Mud crab (Scylla serrata) at least 15 cm carapace width. The trap construction used to capture Scylla serrata in Rembang waters provides an opportunity for capturing juvenile stadia (<10 cm carapace width/CW). The innovation of trap with the escape gap is assumed to pass Scylla serrata juvenille stadia. The design escape gap of a rectangular is located along the underside of the trap with a height of 3 cm, giving the smallest Scylla serrata catches the width of an average carapace by 8.3 cm compared with no escape passes with the smallest size of the average carapace width of 5.3 cm. The capture of Scylla serrata with the trap design of a 10 cm CW (juvenile stadia) trap indicates that the biota population in Rembang waters is small in the case of a study in April to June 2016.

Mangrove crab (Scylla serrata) is one of the prima donna sources of protein caught by fishermen around mangrove forest waters in the waters of the Barumun River Estuary, Labuhanbatu Regency. This study aims to inform about condition factors, growth patterns of crab populations, and reproductive aspects in the form of abundance of Gonad Maturity Level (TKG). Determination of 3 sampling points is done by using purposive random sampling method. Scylla serrata sampling was carried out using Bubu. Data analysis presents information on the abundance of gonadal maturity level, growth pattern, and Fulton condition factor (K), which is presented quantitatively. The results showed that male and female Scylla serrata growth patterns were categorized as negative allometric b < 3, with carapace width growth being faster than weight gain. Fulton condition factor (K) values obtained ranged from 50.14-132.75 for male Scylla serrata, and female ranged from 80.34-123.94. The gonadal maturity level of Scylla serrata was dominated by TKG II crabs, and the lowest abundance of gonad maturity was in TKG IV crabs. This indicates that, in December-February, the condition of the Scylla serrata population around the mangrove forest waters of the Barumun river estuary, is predicted to be in the stage of adult dominance that is ready to reproduce and prepare to spawn.

Abstract Butcher, P. A., Leland, J. C., Broadhurst, M. K., Paterson, B. D., and Mayer, D. G. 2012. Giant mud crab (Scylla serrata): relative efficiencies of common baited traps and impacts to discards. – ICES Journal of Marine Science, 69: . This study was initiated in response to a scarcity of data on the efficiency, selectivity and discard mortality of baited traps to target Scylla serrata. Five replicates of four traps, including “hoop nets”, rigid “wire pots”, and collapsible “round” and “rectangular” pots were deployed for 3, 6 and 24 h in two Australian estuaries. Trapped S. serrata were “discarded” into cages and monitored with controls over 3 d. All S. serrata were assessed for damage, while subsets of immediately caught and monitored individuals had haemolymph constituents quantified as stress indices. All traps retained similar-sized (8.1–19.1 cm carapace width) S. serrata, with catches positively correlated to deployment duration. Round pots were the most efficient for S. serrata and fish—mostly Acanthopagrus australis (3% mortality). Hoop nets were the least efficient and were often damaged. No S. serrata died, but 18% were wounded (biased towards hoop nets), typically involving a missing swimmeret. Physiological responses were mild and mostly affected by biological factors. The results validate discarding unwanted S. serrata for controlling exploitation, but larger mesh sizes or escape vents in pots and restrictions on hoop nets would minimise unnecessary catches, pollution and ghost fishing.

The results showed that b value of male (2.219 – 2.835) and female (1.264-2.352) were significantly different (P<0.05). Male and female crabs have a negative allometric growth pattern with b value of males tend to be larger than females. Range of values for K and Kn male crabs longer than females that male crabs tend to be fatter. Temporal distribution of this mangrove crab condition factors is assumed to be related with the reproductive cycle. The value is increasing since October to a peak season in January which estimated related to a peak of the muddy crabs spawning season in Mantehage Island coastal waters.

Scylla serrata yang dikenal sebagai kepiting bakau merupakan sumber daya hayati ekosistem bakau yang hingga saat ini memiliki demand pasar yang cukup tinggi. Kondisi ini meningkatkan eksploitasi penangkapan species ini sehingga menyebabkan terganggunya populasi kepiting di alam. Penelitian ini bertujuan untuk mengetahui komposisi hasil tangkapan kepiting bakau (Scylla serrata) dengan melihat rasio kelimpahan dan hubungan lebar - berat kepiting bakau jantan dan betina dari hasil tangkapan di perairan Mangkang Wetan – Tugu, Kota Semarang, Jawa Tengah. Penelitian ini dilakukan pada musim penghujan di akhir tahun 2018 (Desember) dan awal tahun 2019 (Januari). Purposive sampling merupakan metode yang digunakan dalam penelitian ini dengan melakukan survey yang terarah dan terencana. Sampel kepiting bakau didapatkan dari hasil tangkapan nelayan yang diarahkan pada lima titik berdasarkan aktivitas yang berbeda. Hasil menunjukkan bahwa tangkapan kepiting bakau (Scylla serrata) pada Bulan Desember 2018 dan Januari 2019 di dominasi oleh kepiting jantan. Tangkapan bulan Desember 2018 memiliki rasio jantan : betina lebih besar (1,65:1) dari Januari 2019 (1,21:1). Korelasi lebar karapas dan berat kepiting bakau jantan dan betina bersifat allometrik, dimana jantan memiliki pola pertumbuhan allometrik positif sedangkan betina memiliki pola perumbuhan allometrik negatif. Dari data tersebut dapat disimpulkan bahwa populasi kepiting jantan lebih banyak ditemukan selama musim penghujan terutama di bulan Desember dan Januari. Ketidak seimbangan sex rasio ini akan menyebabkan terganggunya kestabilan populasi Scylla setrata di ekosistem estuaria Mangkang Wetan Semarang. Scylla serrata known as mangrove crab as an edible food resources of the mangrove ecosystem which has a very high market demand. Due to this conditions will be affected in increasing exploitation of this species and cause inbalancing the population in the nature. The study aims to calculate abundance ratio and width – weight correlation between male and female of the crab caught from the estuary of Mangkang Wetan Semarang, Central Java. This study conducted at the end of 2018 (December) to the first month of 2019 (Januari). Survey method was used in this study by using purposive sampling in order to get the right data aimed as a planned. The crab sample was caught by some fisherman which were dirrected at five sampling points base on different fisherman activities. The results shows that the caught seasons in the rainy time of Dec 2018 and Jan 2019, dominated by males crab (Scylla serrata). The December caught have higher sex ratio between male and female (1,65:1) compare to Januari caught (1,21:1). Correlation in carapage width and body weigth between the crabs male and female shows allometrik growth. Where, the male growth tend to have a positive allometric, while the female were negative. These can be conclude that, the male crabs were dominantly found during rainy seasons especially in December dan January. This imbalance of the sex ratio will disturb the population stability of Scylla setrata in estuary ecosystem of Mangkang Wetan Semarang.

Genetic diversity is the determinant of the allocation of germplasm resources in the genetic improvement of aquaculture species. In this study, three F1 families, including a hybrid Scylla family (S. paramamosain ♂ × S. serrata ♀), a paternal family of S. paramamosain, a maternal family of S. serrata, and two wild populations, including a paternal population of S. paramamosain and a maternal population of S. serrata, were used to investigate the genetic diversity and genetic difference. The results indicated that 98 alleles of nine microsatellites loci were observed in five Scylla populations. The highest average value of Ho (observed heterozygosity), He (expected heterozygosity), and PIC (polymorphic information content) of the wild S. paramamosain population were 0.790, 0.799, and 0.771, respectively, suggesting the wild paternal population has high genetic diversity. The comparative analysis of PIC, Fst (fixation index), and HWE (Hardy–Weinberg equilibrium) indicated that the paternal S. paramamosain may be more suitable for artificial breeding than the maternal S. serrata from the perspective of allele frequency. Analysis of molecular variance analysis (AMOVA) showed that the total genetic variation mainly occurred within populations (73.28%), demonstrating that artificial breeding may induce genetic differentiation of the family groups of Scylla. The results of the analysis of Fst value, UPGMA (unweighted pair-group mean analysis) dendrogram, and genetic diversity indicated that the F1 hybrid offspring had a close genetic distance and high genetic identity with the paternal S. paramamosain populations. It indicated that the F1 hybrid offspring showed potential paternal genetic affinities and a similar potential for artificial breeding with S. paramamosain. The study will provide valuable information to evaluate the difference in the genetic diversity and population structure between hybrid offspring and distinct parental populations of Scylla.

Biodiversitas 18: 1316-1323. The mud crab, Scylla serrata lives associated with mangrove ecosystems and is widely distributed in the Indo West-Pacific. The present work was aimed to reveal the carapace length/width-weight relationships of Scylla serrata in two mangrove ecosystem area of Bulungan District, North Kalimantan- Indonesia, i.e. Kahayan Delta and Tibi Island. The crabs were collected by using ambau pancang (trap) for two months from November to December 2016. A total of 522 individuals were collected and their carapace length, carapace width, and weight were measured. The sex ratio of total collected samples (male to female) was 1:0.79. Carapace length and width of S. serrata caught in these two study area ranged from 40 to 89 mm for male; 32 to 91 mm for female and 59 to 128 mm for male; 53 to 122 mm for female, respectively. The carapace length-weight relationships of total samples showed logarithmic equations as follow: W = -3.2194 + 2.9725 Log CL for male and Log W = -2.2010 + 2.3750 Log CL for female. While the carapace width-weight relationships are as follow: W = -3.9162 + 3.1012 Log CW for male and Log W = -2.6001 + 2.3968 Log CW for female. The b values of carapace width-weight relationship indicated that the growth pattern of male was positive allometric and female was negative allometric. Size frequency of crab population is also presented.

This study was centered around the phylogenetic of mud crab genus Scylla collected across Malaysia based on a 542 base pairs (bp) section of the mitochondrial cytochrome c oxidase I (COI) from 201 individuals. Sampling locations were nine areas including one location from Borneo (Sabah and Sarawak). The Maximum Parsimony (MP) and Neighbor-Joining (NJ) methods was conducted for phylogenetic analysis and performed in MEGA ver. 5.05. We found that S. olivacea is the plenteous species collected with 111 individuals, followed by S. tranquebarica with 61 individuals. Scylla paramamosain is barely found throughout our sampling locations with only 29 individuals caught in this study. Regrettably, no wild samples of S. serrata was found during our sampling occasions, accordingly life specimens were purchased from restaurants to complete the analysis. Both MP and NJ phylogenetic trees shows a monophyletic relationships among all four species within genus Scylla included in this study. This was also supported by the genetic distance analysis based on Tamura-Nei which indicates that there is high interspecific and low intraspecific genetic distances among and within species of Scylla included in the analysis. This investigation divulged a solid proof that supports the occurrence of three species of Scylla with the nonappearance of S. serrata in Malaysian waters. This current investigations could serve as a guidance for promoting further assessment on aquaculture and conservation management for the species.

Mud crabs (Scylla serrata and S. olivacea) are important fisheries resources, but their population in nature is decreasing due to anthropogenic activities, like the deforestation of mangrove forests. Hence, it is crucial to conserve this marine biota for future sustainable use and to conserve our marine biodiversity. Conducting studies on the biological interactions of mud crabs in mangrove habitats can be one of the future conservation approaches. Accordingly, an analysis of the functional relationships between Scylla spp. abundance and the respective mangrove habitat have to be carried out. The research was conducted in the mangrove ecosystem of Bee Jay Bakau Resort Probolinggo (BJBR). Data were collected using line transects and quadrant transects. The Associations between mangroves and mud crab habitat structures were analyzed using the Correspondence Analysis (CA) method. The results show that the relationship matrix between Scylla spp. and the structure of the mangrove habitat is centered on the F1 and F2 factorial axes (89.22%). S. serrata of all size classes were associated with dense mangroves (≥15 trees per 100m2) and high salinities (3-4 ppt), while S. olivacea has shown to be associated with rare to very dense mangrove systems. It indicates that S. olivacea tends to have a higher adaptation rate than S. serrata in this mangrove system. This study will provide information and recommendation for the conservation management of mud crabs and mangrove ecosystems to conserve marine biodiversity.

The cultivation of mud crabs is growing to get crabs in the soft shell condition. But most of the soft shell crab's farmers do not experience sustainable business. The main obstacle is the length of the maintenance period and moulting time does not unison thereby causing the feed and operating costs to be high. The research aimed to examine the effect of injection with forest fern leaf extract on growth rate and moulting speed of mangrove crabs (Scylla serrata) and determine the best dose in the process of injecting forest Fern Leaf extract for mangrove crab (Scylla serrata). Treatment of mangrove crab (Scylla serrata) weight ± 100 g with dose: P1 (NaCL 0.9%) P2 (50 mg.L-1) P3 (75 mg.L-1) P4 (100 mg.L-1) P5 (125 mg.L-1) 5 crabs each are cared for 30 days, The research was conducted using a single complete random draft (RAL), the results of various analyses showed the significant forest fern leaf extract against the growth of absolute weights, the rate of Specific growth, and relative growth, but no noticeable effect for molting speed and absolute length growth. The results of this research showed that a dose of 125 mg.L-1produces the highest value with result for moulting speed of 0.50 ± 0.57, length absolute growth of 0.37 ± 0.1 weighted absolute growth of 20 ± 5,74, specific growth rate of 0.54 ± 0.13, and relative growth of 0.64 ± 0.18.

Ranching, stock enhancement and restocking are management approaches involving the release of wild or hatchery-bred organisms to enhance, conserve or restore fisheries. The present study, conducted from April 2002 to November 2005, evaluated the effectiveness of releasing wild and hatchery-reared (HR) mud crabs in the mangroves of Ibajay, Aklan, Philippines where preliminary studies demonstrated declining fishery yields, abundance and size of crabs. Comparison of survival and growth of wild-released and HR Scylla olivacea and HR Scylla serrata demonstrated the effect of nursery conditioning, size-at-release and species differences. Overall yield and catch per unit effort (CPUE) increased by 46% after stock enhancement trials. Recapture rates of released crabs were highest in wild-released S. olivacea and in crabs measuring 65.0–69.9 mm carapace width (CW) and lowest in non-conditioned HR S. serrata. Growth rates were highest for conditioned HR S. olivacea and lowest for conditioned HR S. serrata (11.7 and 3.7 mm month–1 respectively). Fishing mortality was highest for S. olivacea, whereas natural mortality was greater for S. serrata. Conditioning hatchery-bred animals before release is also important in obtaining higher survival. S. olivacea was the more appropriate of the two species for release in mangrove habitats inundated with low-salinity water. However, there is a need for site-specific studies to evaluate the effectiveness of releases.

The study aimed to investigate the histopathology status of the hepatopancreas of mangrove crabs (Scylla serrata) in the Alue Naga estuary area, Banda Aceh, Indonesia. The research was conducted in September and October 2020. The purposive sampling method was used where the determination of the location was based on water conditions and anthropogenic activities near the estuary. The mangrove crabs (Scylla serrata) sampling location was implemented within three sampling sites in the Krueng Cut estuary, Gampong Alue Naga, Syiah Kuala District, Banda Aceh. Histopathological analysis was carried out in the histology laboratory, Syiah Kuala University. The results showed that there were changes in the hepatopancreas in the form of irregular lumen star shape, the formation of vacuoles and basophilic hypertrophy. These hepatopancreas changes were assumed due to water pollution generated by anthropogenic activities from local settlements and household industries. Therefore, it is suggested to conduct further research regarding water quality parameters and heavy metal concentration within this sampling area.

The biochemical composition (proteins, lipid, ash and moisture) of different parts of the body (gill, meat, egg) of fattened and natural mud crab Scylla serrata was determined. Twenty four samples of S. serrata (12 from wild & 12 from fattening farm) of different sizes and sexes (half of the sample is male) were used in this study. The mean protein and lipid contents are significantly (p<0.05) higher in fattened crabs than natural in natural crabs regardless of size and sexes. Moisture and ash were higher in natural crab than in fattened ones. The highest and lowest moisture content was noticed in gills and eggs in both natural and fattened crabs. Protein and lipid contents were comparatively higher in eggs than in other body parts. Female crabs contained high protein and lipid than males in both natural and fattened crabs. From the results of this study it may considered that fattened crab might be comparatively superior to natural crabs as they appear to provide higher levels of protein and fat for human nutrition.

A precise analytical method was established for rapid screening of 49 antibiotic residues in aquatic products by ultra-high performance liquid chromatography-quadrupole time of flight mass spectrometry (UPLC-QToFMS). The quick, easy, cheap, effective, rugged and safe (QuEChERS) process was refined for effective sample preparation. The homogenized samples of aquatic products were extracted with 3% acetic acid in acetonitrile, salted out with anhydrous magnesium sulfate and sodium chloride, and cleaned up by octadecylsilane (C18) and primary-secondary amine (PSA) powder. Then, the purified samples were separated on a BEH C18 column using 0.1% formic acid and methanol as mobile phases by gradient elution, detected by MS under positive Electron Spray Ionization (ESI+) mode. The linear range of matrix-matched calibration curve was 1–100 μg/L for each compound with the correlation coefficients in the range of 0.9851–0.9999. The recoveries of target antibiotics at the different spiked levels ranged from 60.2% to 117.9% except for lincomycin hydrochloride, whereas relative standard deviations (RSDs) were between 1.6% and 14.0% except for sulfaguanidine in grass Carp, Penaeus vannamei and Scylla serrata matrices. The limits of detection (LODs) (S/N = 3) for the analytes were 0.05–2.40 μg/kg, 0.08–2.00 μg/kg and 0.10–2.27 μg/kg and the limits of quantification (LOQs) (S/N = 10) were 0.16–8.00 μg/kg, 0.25–6.66 μg/kg and 0.32–7.56 μg/kg in grass Carp, Penaeus vannamei and Scylla serrata, respectively. The method was successfully applied to grass Carp, Penaeus vannamei and Scylla serrata, demonstrating its ability for the determination of multi-categories antibiotic residues in aquatic products.

Mud crab (Scylla serrata) burrows in an estuarine mangrove intertidal zone were identified as potential microhabitats for small fishes. The pool-like habitats, created by these burrows, were sampled for fishes during nocturnal and diurnal low tide events, over the new moon period. A total of 1103 fish, comprising a single gobiid species (Redigobius dewaali), were collected from eight burrow-pools. The utilisation of these burrow-pools by large numbers of a single ichthyofaunal species suggests that there is a degree of commensalism between S. serrata and R. dewaali in these intertidal habitats.

Kepiting bakau (Scylla serrata) memiliki nilai ekonomis tinggi. Kebutuhan kepiting bakau selalu meningkat sehingga perlu diupayakan budidaya kepiting bakau secara intensif. Salah satu perkembangan teknologi dalam budidaya perikanan untuk meningkatkan produksi kepiting bakau adalah produksi kepiting cangkang lunak. Kepiting cangkang lunak merupakan kepiting fase ganti kulit (molting) yang mempunyai keunggulan cangkangnya lunak sehingga dapat dikonsumsi secara utuh. Untuk mempercepat kepiting molting diperlukan berbagai rangsangan yang salah satunya adalah menggunakan metode mutilasi. Tujuan penelitian untuk mengetahui perbedaan lama waktu molting dan pertumbuhan berat kepiting bakau dengan menggunakan metode mutilasi pada kaki jalan dan capit. Metode penelitian yang digunakan yaitu metode eksperimental dengan rancangan acak lengkap (RAL) yang terdiri dari empat perlakuan, yaitu mutilasi kaki jalan dan capit, semua kaki jalan, capit, dan alami. Biota yang digunakan berjumlah 40 ekor dengan 10 kali ulangan tiap perlakuan. Data yang diperoleh berupa lama waktu molting serta pertambahan berat mutlak kepiting bakau yang dianalisis menggunakan uji statistik parametrik. Hasil penelitian menunjukkan metode mutilasi berpengaruh terhadap lama waktu molting dengan waktu molting tercepat pada perlakuan mutilasi kaki jalan dan capit rata-rata 13 hari. Metode mutilasi tidak berpengaruh terhadap pertumbuhan berat mutlak dengan nilai tertinggi pada kepiting perlakuan alami sebesar 53,30 gram. Mud crabs (Scylla serrata) are known to have a high economic value. The increasing demand of mud crabs for consumption rxcequires higher production. Therefore, mud crabs need to be cultivated intensively. One of the methods to improve the values of mud crabs’ aquaculture is by producing soft-shell crabs. Soft-shell crabs are produced during molting phase in which the crab shed it’s exoskeleton in order to grow. In the fisheries industry, the soft-shell crabs are considered to be more valuable as it can be consumed as a whole. Accelerating the production of molting crabs, requires stimulus. One of the methods is mutilation. The aim of this study is to estimate the periods required for molting under different treatments, as well as calculating the increase of total weight of molting crabs.. The method used was an experimental method which contained four treatments. The treatments are mutilation of walking legs and claws, all of walking legs, claws, and no mutilation. The number of crabs used was 40 with 10 replications per treatment. The data obtained in the period of molting and the increase of total weight of the mud crabs were analyzed using ANOVA. The result shows that mutilation affects the period of crab’s molting in which the fastest molting (13 days on average) occurred after mutilation of walking legs and claws. This mutilation method does not influence the increase of total weight and the highest value is showed in non-treated group with the increase of 53,30 grams in weight.

Mud crab is one of fishery commodities which is important in Indonesia . The high demand for mud crabs needs to be balanced with the right management strategy, so that the population will not extinction. Penikel Village, Cilacap is one of the fishing villages which catch mud crabs because of the high demand in the big cities such as Jakarta, Bandung and Bali. The purpose of this study is to determine the population and growth patterns of mud crabs in the Panikel Village, Kampung Laut District, Cilacap. The location of the study was determined by purposive sampling. Wadong and bubu are fishing tools to catch mud crabs. Sampling 67 mud crabs was carried out on Juni 2016, after that, measurement of length, carapace width and total weight were carried out. Regression analysis between carapace width and total weight and condition factors were carried out to determine growth patterns. Based on the research, the average value of the S. serrata length was 63.94±11.31 mm while the female one was 70.29±14.57 mm. The average value of carapace width is 92.28±15.51 mm (male) while for female sex was 98.71±18.38 mm. The average weight of S. serrata male crabs was 190.31±118.43 mm, while those of female sex were 210.77±120.93 mm. Furthermore, based on the analysis of the relationship between the length of weight found negative allomatric growth pattern with the value of the condition factor included in the low category both for male sex 0.73-1.93 and for female sex 0.59-1.66. The low condition factor shows that the condition of Segara Anakan waters especially Penikel Village does not support the growth of mud crabs (S. serrata). Kepiting bakau (Scylla serrata) merupakan salah satu komoditas perikanan yang terpenting di Indonesia. Besarnya permintaan kepiting bakau yang tinggi perlu diimbangi dengan strategi pengelolaan yang tepat agar populasi tidak punah. Desa Penikel, Cilacap merupakan satu desa nelayan yang banyak menangkap kepiting bakau karena tingginya permintaan di kota besar seperti Jakarta, Bandung dan Bali. Tujuan dari penelitian ini untuk mengetahui populasi dan pola pertumbuhan kepiting bakau di Desa Panikel, Kecamatan Kampung Laut, Cilacap. Penentuan lokasi penelitian dilakukan secara purposive sampling. Wadong dan bubu merupakan alat tangkap untuk menangkap kepiting bakau. Pengambilan sampel kepiting sebanyak 67 individu dilakukan pada bulan Juni 2016, setelah itu dilakukan pengukuran panjang, lebar karapas serta berat total. Analisa regresi kurva antara lebar karapas dan berat total serta faktor kondisi dilakukan untuk mengetahui pola pertumbuhan. Berdasarkan penelitian diperoleh nilai rata-rata panjang kepiting bakau S. serrta jantan adalah 63.94±11.31 mm sedang untuk yang betina adalah 70,29±14.57 mm. Nilai rata-rata lebar karapas adalah 92.28±15.51 mm (jantan) sedang untuk jenis kelamin betina adalah 98.71±18.38 mm. Rata-rata berat kepiting jantan S. serrata adalah 190.31±118.43 mm, sedangkan yang jenis kelamin betina adalah 210.77±120.93 mm. Selanjutnya berdasarkan analisa hubungan panjang berat ditemukan pola pertumbuhan allomatrik negatif dengan nilai factor kondisi termasuk dalam katagori rendah baik untuk jenis kelamin jantan 0,73–1,93 maupun untuk kelamin betina 0,59–1,66. Rendahnya factor kondisi menunjukkan bahwa kondisi perairan Segara Anakan khususnya Desa Penikel tidak menunjang bagi petumbuhan kepiting bakau (S. serrata).

Meningkatnya permintaan kepiting untuk ekspor terutama disebabkan kelezatan dan kandungan gizi dagingnya. Namun pada umumnya masih berasal dari hasil tangkapan dari alam, oleh karenanya peningkatan teknologi budidaya sangat penting. Penelitian ini bertujuan untuk mengetahui pengaruh jenis kelamin, jenis pakan dan metode pembesaran terhadap pertumbuhan kepiting.Penelitian dilakukan dengan metode eksperimental, dalam menganalisis pengaruh variable menggunakan rancangan acak kelompok dengan pola faktorial 2x2x3. Laju pertumbuhan mutlak dan pertambahan berat diukur setiap minggu. Hasil penelitian menunjukkan bahwa kepiting jantan dipelihara secara individu dengan pakan ikan mempunyai pertumbuhan mutlak tertinggi yaitu 1,07 g.hari-1 dan pertambahan berat (weight gain) tertinggi pula yaitu 84,73%. Pemeliharaan massal, kepiting betina dengan pakan ikan rucah memiliki laju pertumbuhan mutlak tertinggi yaitu 0,80 g.hari-1. Sedangkan weight gain tertinggi diperoleh pada kepiting jantan yang diberi pakan ikan yaitu 52,03%. Anova tes menunjukkan pengaruh jenis kelamin dan interaksinya berbeda nyata. Hal ini menunjukkan bahwa pertumbuhan kepiting dengan pakan ikan rucah lebih tinggi dibandingkan kepiting dengan pakan kerang dan campuran dari ikan dan kerang. Kepiting jantan yang dipelihara secara individu diberi pakan ikan rucah tumbuh lebih baik dibandingkan kepiting betina. Pertumbuhan Kepiting betina yang dipelihara secara massal dan diberi pakan ikan rucah memiliki peertumbuhan paling tinggi. Kata kunci: pertumbuhan, jenis kelamin, pakan alami, Scylla serrata, wadah pemeliharaan The increase of the export demand of crabs (Scylla serrata), among others caused by the good taste and have a very high nutrition value, but most of the crab still collected by fishing of natural stock. Therefore, technology of crabs culture should be enhanced. This research was aiming to understand the influence of sexual, feeding regime, environmental factors to the growth rate. This research was conducted experimentally using the randomized block design with factorial pattern 2x2x3. The growth rate and weight gain were measured weekly. The results show that male crab reared in individual aquarium fed by mixed fish revealed the quickest ultimate growth rate i.e. 1.07 g.day-1, as well as achieving the highest weight gain i.e. 84.73%. While in mass rearing method, female crab fed by mixed fish achieved the highest ultimate growth rate ie. 0.8 g.day-1, and the highest weight gain achieved in male crab fed by mixed fish i.e. 52.03%. Anova test reveal that sexual factor and it’s interaction was significantly different. The research conclude that the growth of the crab fed by mixed fish was higher than those fed by bivalve meat or combination of mixed fish with bivalve meat; male crab reared individually and fed with mixed fish revealed has higher growth rate then the female crab; and the growth rate of female crab reared in a mass and fed by mixed fish revealed the highest growth rate.
