Streszczenie:
Namena is Fiji’s oldest and second largest no-take marine reserve, and has relatively high abundance and biomass of targeted fishes within its boundaries due to a high level of protection since its creation in 1997 (formalised in 2005). Following anecdotal reports of exceptionally high fish abundance at the Grand Central Station dive site within Namena, we conducted a 500-m meandering diver-operated video transect along the main reef formation, to obtain abundance, length and biomass estimates for fish species targeted by local fishers. Our census revealed extremely high diversity, abundance and biomass (11436kgha−1) of targeted fishes. While demersal reef fishes were present at higher densities than on typical fished reefs in the region, they were dwarfed by aggregations of reef-associated pelagics, namely the barracuda Sphyraena forsteri (5540kgha−1) and the trevally Caranx sexfasciatus (4448kgha−1). These estimates are comparable to those of historically unfished or ‘pristine’ locations, an unexpected finding given the historical fishing pressure within the reserve before its establishment and ongoing pressure in surrounding fished areas. This finding presents Grand Central Station as a useful reference site for ecologists and managers, and highlights the ability of protected coral reefs to support or attract very high densities of fish.

Abstract I describe my personal evolution as a modeller of behaviour, both human and (non-human) animal behaviour, using dynamic state-variable models. At first I worked in renewable resource Economics, especially the economics of marine fisheries where I collaborated extensively with Gordon R. Munro. Subsequently, in collaboration with Marc Mangel (and many field biologists) I worked in Behavioural Ecology. Mathematical models have played a major role in both of these subjects, but until recently mostly static models were used, on the grounds that dynamic (not to mention stochastic) models were too difficult to work with. I express the hope that our use of relatively simple (but not too simple) dynamic models has established the fact that such models can be extremely helpful, perhaps essential, in understanding many aspects of behaviour.

Streszczenie:
SUMMARYHumans can impact coral reef fishes directly by fishing, or indirectly through anthropogenic degradation of habitat. Uncertainty about the relative importance of those can make it difficult to develop and build consensus for appropriate remedial management. Relationships between fish assemblages and human population density were assessed using data from 18 locations widely spread throughout the Main Hawaiian Islands (MHI) to evaluate the significance of fishing as a factor potentially driving fish trends on a regional scale. Fish biomass in several groups was negatively correlated with local human population density and a number of lines of evidence indicate that fishing was the prime driver of those trends. First, declines were consistently evident among fish groups targeted by fishers, but not among lightly fished or non-target groupings, which indicates that declines in target groups were not simply indicative of a general decline in habitat quality along human population gradients. Second, proximity to high human populations was not associated with low fish biomass where shoreline structure prevented ready access by fishers. Relatively remote and inaccessible locations within the MHI had 2.1–4.2 times the biomass of target fishes compared to accessible and populous locations, and may therefore function as partial refugia. However, stocks in those areas were clearly far from pristine, as biomass of large predators was more than an order of magnitude lower than at more intact ecosystems elsewhere in the Pacific.

Streszczenie:
Marine reserves are widely considered to potentially benefit reef fisheries through emigration, yet the empirical basis for predicting the extent of this for small reserves is weak. The effects of fishing pressure and habitat on biomass and catch per unit effort (CPUE) of three species of exploited reef fish were studied at South Caicos, Turks and Caicos Islands. Distribution and abundance of hogfish (Lachnolaimus maximus) and white margate (Haemulon album) were inversely correlated with cover of fleshy macroalgae. Nassau grouper (Epinephelus striatus) were positively associated with vertical relief, but were unaffected by algal cover. Mean size, density, and biomass of hogfish were higher in a small (4 km2) marine reserve than on fished reefs, as was biomass of white margate. CPUE of hogfish was inversely related to distance from the centre of the reserve, suggesting that spillover of this species from the reserve to adjacent reefs may enhance local yields, possibly providing economic incentives for fishers to comply with reserve regulations. Fishing pressure, however, had no apparent effect on Nassau grouper. Larger fishes and those that migrate to spawn, such as economically valuable Nassau grouper, may move over too large a range to be effectively protected by small marine reserves. Small reserves may not protect all fish, but they can increase the biomass of smaller or more sedentary reef fishes and may be a useful tool for the conservation or management of species such as hogfish. Other policy options, such as seasonal spawning closures or total allowable catches, need to be considered for larger, more mobile fishes in the Turks and Caicos Islands.

Effects of feeding ratios (3%, 5% and 7%) on growth and food conversion rate (FCR) of common carp Cyprinus carpio reared in floating cages at Shatt Al-Arab River, Hartha district were studied during a period of 27-4-2010 to 28-6-2010. Statically analysis of results proved that there were significant differences between final weight and length reached by fishes fed on 3% of fish weight and fished fed on 5% and 7% of fish weight. Final weights of fishes were (188, 275.8 and 252.6) g and final lengths were (216.6, 234.6 and 227.2) mm for (3, 5 and 7)% feeding ratio respectively. Better results of growth and FCR obtained from fishes fed 5% of fish weight. Results appeared that FCR values were 4.82, 2.63 and 3.98, daily growth rates were (1.07, 3.16 and 2.78) g/day and specific growth rates were (0.7, 1.85 and 1.71) %/day for fishes fed 3, 5 and 7% of fish weight respectively.

We examined the distribution and abundance of glochidia of the freshwater mussel Anodonta kennerlyi Lea, 1860 on local fishes in three temperate rain forest lakes near Bamfield, on the west coast of Vancouver Island, British Columbia. Fishes involved in the life cycle of the mussel were the prickly sculpin (Cottus asper Richardson, 1836), threespine stickleback (Gasterosteus aculeatus L., 1758), Dolly Varden (Salvelinus malma (Walbaum, 1792)), and cutthroat trout (Oncorhynchus clarkii (Richardson, 1836)). For each lake, we assessed which fish was the most important for larval propagation and recruitment of the mussel by considering the fish's primary habitat, the percentage of fish in a sample with glochidia, and the abundance of glochidia on sampled fish. Also, an alternative method for quantifying the glochidia's "preference" for a host consisted of measuring the number of glochidia per unit area of fish body surface (larval density). We digitized the surface area of fins and head, i.e., the areas used by glochidia for settlement. Every fish species in each lake dispersed the glochidia. There was, however, a sharp gradient in the intensity of the fish–mussel linkage among fishes. Fishes that co-occurred most often with mussels, such as sculpins and sticklebacks, had the highest density of glochidia. Larval density on fishes also revealed the existence of between-lake differences in glochidia preference.

Because of problems with insecticide resistance, alternative malaria control methods were necessary. These methods include the use of biological control agents, such as larvivorous fish. This study aimed to compare the larval eating capacity of two indigenous larvivorous fishes in malaria vector control in laboratory conditions in Dogbo district in south-western Benin. Larvae of Anopheles gambiae sensu lato mosquitoes were collected from breeding sites using the dipping method in July 2020 during the rainy season in Dogbo district. Alive Clarias gariepinus and Orechromis niloticus fishes were bought immediately once catched by fishers of Ganvié location in So-Ava district and carried by car from Ganvié location to the Laboratory. Laboratory evaluation for larvivorous efficacy was conducted. The results obtained in the current study showed that the larval eating capacity of Clarias gariepinus fish when this fish was fed was higher than that of Orechromis niloticus indigenous larvivorous fish in the laboratory conditions. Similar results were obtained when these different fishes were unfed. In a context of environmental crisis and global changes, environmentally friendly methods should be encouraged. The use of indigenous larvivorous fishes as predators to control malaria mosquitoes is obviously insufficient in the current study.

Eight samples of varying qualities and ages of surimi were used in the development of a new method for testing the quality of surimi. The effects of salt, pH, concentration, heating temperatures and times, and cooling times were observed. These results were used in the development of the McRae-Manning Test. By employing this method, it was possible to determine the difference between fresh high quality surimi, fresh low quality surimi, and old surimi. For this test, surimi was mixed at a 15% concentration, heated at 90 C for 20 minutes in plastic syringes, cooled and evaluated. The surimi was evaluated by emptying the samples onto prepared transparent sheets and measuring how far the sample spreads with time. The transparent sheets had circular measurements which indicated the amount of spread. Best results were obtained when the sheets were elevated at one end.

Streszczenie:
Chrysoblephus puniceus is an over-exploited linefish species, endemic to the coastlines off southern Mozambique and eastern South Africa. Over-exploitation and habitat loss are two of the biggest threats to the sustainability of fisheries globally. Assessing the genetic stock structure (a prerequisite for effective management) and predicting climate related range changes will provide a better understanding of these threats to C. puniceus which can be used to improve the sustainability of the fishery. Two hundred and eighty four genetic samples were collected from eight sampling sites between Ponta da Barra in Mozambique and Coffee Bay in South Africa. The mitochondrial control region and ten microsatellite loci were amplified to analyse the stock structure of C. puniceus. The majority of microsatellite and mtDNA pairwise population comparisons were not significant (P > 0.05) although Xai Xai and Inhaca populations had some significant population comparisons for mtDNA (P < 0.05). AMOVA did not explain any significant variation at the between groups hierarchical level for any pre-defined groupings except for a mtDNA grouping which separated out Xai Xai and Inhaca from other sampling sites. SAMOVA, isolation by distance tests, structure analysis, principle component analysis and spatial autocorrelation analysis all indicated a single population of C. puniceus as being most likely. The migrate-n analysis provided evidence of current driven larval transport, with net migration rates influenced by current dynamics.Two hundred and thirty six unique presence points of C. puniceus were correlated with seasonal maximum and minimum temperature data and bathymetry to model the current distribution and predict future distribution changes of the species up until 2030. Eight individual species distribution models were developed and combined into a mean ensemble model using the Biomod2 package. Winter minimum temperature was the most important variable in determining models outputs. Overall the ensemble model was accurate with a true skills statistic score of 0.962. Binary transformed mean ensemble models predicted a northern and southern range contraction of C. puniceus' distribution of 15 percent; by 2030. The mean ensemble probability of occurrence models indicated that C. puniceus' abundance is likely to decrease off the southern Mozambique coastline but remain high off KwaZulu-Natal. The results of the genetic analysis support the theory of external recruitment sustaining the KwaZulu Natal fishery for C. puniceus. While the high genetic diversity and connectivity may make C. puniceus more resilient to disturbances, the loss of 15 percent; distribution and 11 percent; genetic diversity by 2030 will increase the species vulnerability. The decrease in abundance of C. puniceus off southern Mozambique together with current widespread exploitation levels could result in the collapse of the fishery. A single transboundary stock of C. puniceus highlights the need for co-management of the species. A combined stock assessment between South Africa and Mozambique and the development of further Marine Protected Areas off southern Mozambique are suggested as management options to minimise the vulnerability of this species.

Streszczenie:
Water quality impairment due to anthropogenic activities affects fishery resources. Surface water bodies in the Niger Delta Region of Nigeria are being adversely impacted by the effects of pollution and the destruction of its fishery resources. This study was carried out to assess the impacts of anthropogenic activities on the fish compositions and diversity of Okerenkoko Estuarine, Delta State, Nigeria. Okerenkoko Estuarine (62.79 Km) was spatially stratified into five stations (Z1, Z2, Z3, Z4 and Z5) based on nearness to major anthropogenic activities. Temporal stratification covered June to December. Fish samples were collected for 7 months from each station at the study area with prior arrangement with the fishers. Fishing gears used were Mid – Water Drift Gill Net of mesh sizes 101 mm and 127 mm; Bottom Set Gill Net (50 – 100 m) of mesh size 76 mm, 101 mm and 127 mm; Hook and line (2 – 6 m) of hook sizes No. 5, No. 7, No. 8, No. 9, No. 12 and No. 15; Long Line (300 – 1000 m) of hook sizes No. 7, No. 8. Parameters determined were Numbers of Species, Abundance (%), Simpson and Shannon by using standard procedures. Data were analysed by using Excel (Window 10) and Palaeontological Statistics (Past Version 3.6). A total number of 1261 of fishes and 45 species belonging to 14 families were identified. Highest 383 (30.4 %) and least 152 (12.1 %) number of fishes were obtained in Z5 and Z4, respectively. The most abundant fish species recorded was Sardinella aurita 192 (15.2 %), while the least was Sphyraena afra 1 (0.1 %), respectively. Temporally, the highest 331 (26.2 %) and least 45 (3.6 %) fish species Occurred in December and September. Simpson index ranged from 0.69 to 0.89 in Z1 and Z3, Shannon (1.97, 2.98) occurred in Z4 and Z2, respectively. Fish biodiversity richness (0.69) of Okerenkoko Estuarine could be threatened.

Biomimetics or biomimicry is the emulation of the systems, ele-ments and models of nature for the in order to solve complicated problems. There are various biomimetics model which are developed for various opera-tions like underwater explorations, water pH detection, to check the pollution level of water, etc. This report is mainly focused of designing of fish geome-try for rescue operation. Based on the movement of real fishes, a tail me-chanical structure for fitting a carangiform of fish body wave motion is de-signed. Co-ordinating the motions of the pectoral fins and tail fin, the robotic fish can simulate the motion of real fishes in water. Basic understanding of components required for developing fish swim motion are studied. Finally, the CAD model of fish is presented followed with the simulation and prepa-ration of primary prototype.

Abstract While the industry has many recommendations on fishing operations and setups, a process of the selection for overshots, and a streamline when similar fish or wellbore conditions has not been discussed before. This paper will review a challenging case history well, with multiple fishes of the same type, and the lessons learned on selections with varying wellbore conditions. Taking into measure was the learnings from the post well review, and the creation of a flowchart to better optimize the selection of fishing Bottom Hole Assembly's (BHA). This incorporated the coordination of charts’ creation with the service provider, ensured a robust process with multiple choices and supportive reasoning for selection. The well primarily discussed in this paper, was a horizontal well in a tight gas field. The knowledge gained from the multiple fishes in the case study horizontal well, streamlined future choices in BHA selections for similar fishes. As an operator, having the flowchart encourages more discussion with the service company, and supports the engineers in planning operations.

In the study of the mechanisms of schooling behavior of fish, it becomes necessary to process large amounts of visual information. Early this processing was done mostly by hand. The paper study the possibility of automating the processing of observation results using the open CV computer vision package. Both individual frames and video fragments (scenes) of observations were processed. To process individual frames, a program was written for automatically counting the number of fishes in a school, another programs were written for determining the position of fishes and the degree of polarization of a group. During processing fragments of observations (scenes) the video scenes of fright of the school and video scenes of interaction between the predator and the school were considered. When studying the fright scene, a program for determining the speed of movement of individuals, a programs for calculating the kinetic energy of an individual moving and the kinetic energy of a group of fishes were built. The concept of the fright’s magnitude caused by a short local perturbation is introduced, and a method is proposed for numerically measuring the magnitude of the fright. When studying the scene of interaction between a predator and a school, a program for tracking the movement of an individual in a school was built. The proposed methods can be used in constructing and identifying the parameters of mathematical models of schooling fish movement.
