Résumé :
The Peppered loach, Lepidocephalichthys guntea is the least concerned freshwater species, commonly found in India, Pakistan, Nepal, and Bangladesh. In West Bengal, it is popularly known as “Guntey” & it has commercial and food value. The current study aimed to the estimation of the length-weight relationship, condition, and relative condition factor (Kn) of the fish species Lepidocephalichthys guntea, habitats of Kangsabati river in the District West Midnapore, West Bengal, India. Total 161 numbers of species were collected between August 2019 to July 2020 and considered for examination. The fishes ranged from 5.4 to 10.7 cm in total length & 0.72 to 9.73 g in weight. The scatter diagram exhibits a linear relationship between the log length & log weight. The female species has a higher “b” value (b=3.452, P<0.05), which is greater than 3 which justifying a positive allometric growth. The parabolic equation among total length and weight of L. guntea is labeled as W= 0.008744991 L 2.7496 for males, W= 0.002153098 L 3.452 for females & W= 0.007575793 L 2.8155 for the combination of male and female species. Higher r2 (0.859, P<0.05) value in combined of male & female justifying a strong relationship between length and length. The mean condition(K) & relative condition factor (Kn) values were found to be the height in the male category with "K" value 0.654 & "Kn” value1.174 respectively indicating the well-being of the species. Although, this species does not sternly follow the cube law & shows a well status of health condition in their natural habitat.

Résumé :
Four loaches, namely, Lepidocephalichthys guntea (Hamilton, 1822), Lepidocephalichthys annandalei (Chaudhuri, 1912), Lepidocephalichthys thermalis (Valenciennes, 1846), and Lepidocephalichthys berdmorei (Blyth, 1860) from the Cobitidae family, were collected from the Surma River, Bangladesh. Of the total 376 speciminia, 193 males (51.32%) and 183 females (48.67%) in number; were collected with the support of local fishermen using a variety of nets at 15-day intervals from November 2022 to April 2023. The length-weight relationship (LWR) parameters were analyzed using the equation W = a L b . L. annandalei displayed a notable isometric growth pattern, with a condition factor (K) ranging from 0.725 to 0.734. In addition, L. thermalis exhibited isometric growth among males, while females showcased positive allometric growth with a condition factor (K) varying between 0.697 and 0.714. L. guntea exhibited a consistent positive allometric growth pattern across all aspects, with a condition factor (K) ranging from 0.729 to 0.738. In contrast, L. berdmorei demonstrated positive allometric growth, but males and females both exhibited a negative allometric growth pattern. The condition factor (K) for L. berdmorei ranged from 0.699 to 0.702. This suggests a complex growth pattern influenced by both length and weight in every experimental loach. The research underscores the importance of recognizing gender-specific variations in growth patterns within species.

Résumé :
Abstract The cellular organizations of intestine in Lepidocephalichthys guntea (Hamilton, 1822) have been described by light as well as scanning and transmission electron microscopy. The intestine is short and straight like, marked into anterior, middle and posterior region based on mucosal folds, number and size of columnar epithelial cells and mucous cells, thickness of submucosa and muscularis layer. The mucosa of anterior intestine forms high folds, which are lined with compactly arranged columnar epithelial cells and mucous cells. In the middle intestine, folds are pointless whereas the posterior intestine is without folds. The submucosa is formed of thin layer of connective tissue, contained collagen bundles and blood capillaries, comparatively well developed in the posterior intestine. By scanning electron microscopy, outlines of the luminal surface of anterior and middle intestine is embossed with oval or rounded columnar epithelial cells contained densely packed stubby microridges. The posterior intestine has closely set longitudinal folds characterized with minute blood capillaries and columnar epithelial cells having inconspicuous microridges. Ultrastructurally, the mucosal surface of the intestine consists of mucous cells with electron dense granules and columnar epithelial cells having numerous microvilli, mitochondria, endoplasmic reticulum, lysosomes and Golgi body. Cellular components of the anterior and middle intestine participate in the absorption whereas the presence of enormous blood vessels and capillary net work of posterior intestine probably responsible for air breathing.

Résumé :
This study was conducted to determine the biochemical composition of Botia dario and Lepidocephalichthys guntea collected from different regions in Bangladesh. Samples were collected from fishermen during the study period. Fishing activities were done either by dewatering process or by using fishing gears. Different types of gear were used to collect fish samples includes lift net, push net, cast net, and other fishing gear. For B. Dario the moisture content was 68.50%, ash content was 2.72%, crude protein content was 15.50 %, lipid content was 12.21%, and carbohydrate content was 1.07% in wet weight basis and 12.50% moisture, 8.68% ash, 63.2% crude protein, 13.07% lipid, and 0.11% carbohydrate was in dry matter basis. The nutritive components of L. guntea fish were 77.89% as moisture, 3.09% as ash, 16.54% as crude protein, 1.53% as lipid, 0.95% as carbohydrates on a moisture basis, and 10.11% as moisture, 13.84% as ash, 64.70% as crude protein, 6.92% as lipid, 4.43% as carbohydrates on a dry matter basis. The overall study revealed that B. dario and L. guntea are very rich in nutrient composition. All of the information will be helpful for researcher and policy makers for proper conservation and management of these fish.

Résumé :
The study on morphometric and meristic characters of two species of fresh water fishes under order Cypriniformes were carried out in Ichthyology laboratory of Zoological Survey of India, Northern Regional Centre, Dehradun. During the present investigation, 2 families under Cyprinidae and Cobitidae fish species are molacarplet, Amblypharyngodonmola Hamilton (1822) and Lepidocephalichthys guntea (Hamilton, 1822) were identified. The 22 morphometric and 5 meristic counts were studied from Song River, Dehradun. The result showed that all the morphometric characters of two fishes are dependent on the total length. The analyzed data of morphometric dimensions of fish species would be beneficial for the policy makers or planners to develop the scientific strategies for their protection and conservation. The findings will also set the scientific principles for the management and sustainable development of the commercially essential freshwater food fishes.

Résumé :
The North Eastern Sates including Assam are very rich in aquatic bio-resources and dominated by several endemic fish resources. The study was conducted from June 2018- July 2019 in two different fish assembling villages viz. Chamaguri (W) and Garokuta (North) of Urpad Beel and fish species were recorded along with their IUCN Conservation status. Alto-gether, 31 ornamental fish species belonging to 16 Genera, 15 Families, and 6 Orders be-longing to orders like Beloniformes, Cypriniformes, Osteoglossiformes, Siluriformes, Sym-branchiformes, Perciformes, Tetradontiformes were recorded. Out of the recorded fish spe-cies, Lepidocephalichthys guntea (Hamilton-Buchanan,1822), Channa gachua (Hamilton, 1822) and Chanda nama (Hamilton, 1822) were assessed as NE, Botia rostrata (Gun-ther,1868) and Channa gachua (Hamilton, 1822), Mystus vittatus ( Bloch, 1794) as VU, Ctenops nobilis (Mc Clelland, 1845) as NT as per IUCN Status 2013. The ornamental fishes are found in the weed assemblage of the Beel including Eichhornia crassipes, Hydrilla verticillate and Ceratophyllum demersum .

Résumé :
The correlations between fisheries diversity and environmental variables of Nepal’s Pond are poorly understood. This study aims to investigate temporal variation of fish assemblage at Taruwa Pond in Nawalparasi district, Province no. 4, Nepal from October 2018 to April 2019. For the fish agglomeration, cast net of 4 kg in weight and 3.80 m in length and 22.5 m breadth with 12 mm mesh size was used. In total, 579 individuals representing 16 fish species, 10 families, and 12 genera were recorded. According to similarity percentage analysis, the most contributory species were Puntius ticto (27.92%) followed by Danio devario (12.06%), Puntius terio (9.76%), Badis badis (7.31%), Lepidocephalichthys guntea (5.57%) and Puntius sophore (5.57%). Analysis of similarity suggested that fish community structure was significantly different in temporal variation (R = 0.321, p<0.01). Based on the cluster analysis, fish assemblages were isolated into two distinct groups at Bray-curtis similarity. The Canonical Correspondence Analysis distinctly indicated that the water parameters of dissolved oxygen, carbon-dioxide, depth, and water temperature play an important role in influencing the fish assemblage structure of Taruwa Pond.
