Toxicity Level

Four fish species namely, stinging catfish (Heteropneustes fossilis), spotted snakehead (Channa punctatus), climbing perch (Anabas testudineus) and tangra (Batasio tengana) were exposed to various concentrations of chlorpyrifos (Expert 20 EC) to investigate the mortality rate of fish species and the toxicity level of the pesticide. The LC50 values of chlorpyrifos on these fish species were 23.10, 20.32, 16.61 and 13.94 ppm, respectively at 96 hours of exposure. Among these results, it is clear that the lethal concentration is varying species to species because their strengths are different. During the experiments, some water quality parameters such as temperature, pH, dissolved oxygen, total dissolved solids and electrical conductivity were also analyzed. The temperature values remained within the ranges of 17-20°C and the pH was 6.64-7.30. Fish behaved irregular and erratic movements followed by hyper excitability, loss of balance and settling to the bottom of the test chamber. At higher concentration of chlorpyrifos, alterations in physiological and behavioural responses especially erratic swimming, gulping, mucus secretion, increased opercular movement and profuse emission of mucus all above the body were observed during the primary stages of contact after which it became occasional.

Certain water quality parameters are known to cause serious problems to fish, especially when they are living under intensive farming conditions. These problems range from discomfort of fish to heavy mortalities and factors, such as the fish species, the time and level of exposure and the synergic effect of other coexisting stressful conditions, play an important role. In addition, when these parameters are outside the preferable for each fish species range, they can induce stress to fish, compromising their immune system and making them vulnerable to many opportunistic pathogens. Oxygen is, probably, the main limiting factor under farming conditions and when its levels are below the preferable range for any fish species, many morphological, as well as physiological alterations develop. Increased levels of carbon dioxide in the water usually coexist with decreased levels of oxygen and can cause respiratory acidosis and nephrocalcinosis. The latter is characterized by the development of granulomas in many internal organs and urolithiasis. Ammonia usually causes problems under intensive farming conditions, especially when the wateris recirculated and the pH is high. Increased levels of ammonia in the water can cause extensive alterations in the gills and degenerative changes in the liver and kidney. Gas supersaturation of the water, depending on the level of saturation and the time of exposure, can result in the gas bubble disease. Formation of bubbles in the eyes, skin and gills and extensive necrotic areas inmany organs due to gas emboli are the main findings caused by this disease. Many contaminants in the water can, also, create serious problems to fish. Fin erosion, epidermal hyperplasia or papilloma and degenerative and necrotic alterations in many internalorgans are common findings observed in fish on many cases of water pollution. Many of the factors mentioned above, as well as others, such as nutrition and bad management, can result in abnormal development of the body offish, when exposed at their early life stages. Due to farming conditions, cultured fish tend to exhibit increased rate of body malformation compared to wild ones. Careful design of the facilities, use of specialized equipment and, probably, application of genetic selection program can minimize or even eliminate the effects these water parameters have on the cultured fish.

The authors of the article have studied the content of the elements of anti-oxidant system (malondialdehyde, catalase, selenium) in tissues of the internal organs (gills, intestine, muscles, liver, swimbladder, scales) in some species of predatory fish (pike Esox lucius (L., 1758), perch Perca fluviatilis (L., 1758), pike-perch Sander lucioperca (L., 1758), catfish Silurus glanis ) widespread in the basin of the Volga river in the Saratov region. The lowest concentration of malondialdehyde in organisms of the studied fish species is observed in fall and winter; the highest - in spring and summer. Catalase activity in gills tissue of a pike raised in 11.8%, cat-fish - 9.1%, pike-perch - 7.5%, perch - 7.8%. In fall (compared to winter) enzyme activity lowering in gonads of pike-perch makes 16.3%, in gonads of perch - 14.4%. In other tissues there were not observed any evident changes of catalase activity. Fish species under consideration are listed according to the average value of selenium concentration in organisms, µg/g: pike (0.208) > catfish (0.207) > pike-perch (0.196) > perch (0.178). According to the average value of the selenium accumulation in the body in different season all the studied species can be placed in the following order, µg/g: winter-pike (0.132) > pike-perch (0.136) > perch and catfish (0.142); spring - pike-perch (0.190) > perch (0.191) > pike (0.208) > catfish (0.209); summer - perch (0.186) > pike-perch (0.190) > catfish and pike (0.203); autumn - perch (0.193) > pike-perch (0.268) > > catfish (0.274) > pike (0.289).

Based on a fish survey and preliminary underwater observations, 17 "morphotypes" were identified that characterize the morphological diversity found within 27 nektonic fish species sampled at São Sebastião Channel. Such "morphotypes" were studied using an ecomorphological approach, with the intention to investigate similarities and differences in shape and habits. Underwater field observations were also performed, to verify if the lifestyle of these species, such as vertical occupation of the water column and the habitat use, are in accordance with their distribution in the morphospace. The results, complemented with data from scientific literature on the taxonomy and phylogenies of these species, allowed discussing some of the typical cases of convergent and divergent evolution. Some of the ecomorphological clusters had no phylogenetic support although this is probably due to the environmental conditions in which theirs members have evolved. The body shape and fins positions of a fish clearly influence its ecological performance and habitat use, corroborating the ecomorphological hypothesis on the intimate link between phenotype and ecology.

                                                                   AbstrakAsam amino adalah komponen terkecil yang menyusun protein. Sejumlah asam amino akan dihubungkan satu sama lain melalui perantara ikatan peptida untuk membentuk protein. Asam amino telah dibagi menjadi dua; yaitu asam amino esensial dan asam amino non-esensial. Asam amino esensial adalah asam amino yang tidak dapat disintesis oleh tubuh ikan; karena itu asam amino esensial harus ada dalam pakan. Lisin adalah salah satu dari sepuluh asam amino esensial, fungsi lisin adalah untuk pertumbuhan dan perbaikan jaringan tubuh. Penelitian ini bertujuan untuk mengetahui pengaruh lisin dalam pakan komersial terhadap retensi protein dan retensi energi ikan bawal air tawar. Metode yang digunakan adalah desain eksperimen rancangan acak lengkap. Perlakuan yang digunakan adalah kadar lisin yang berbeda, yaitu P0 (0%), P1 (0,6%), P2 (1,2%), P3 (2,4%), P4 (4,8%) dan perlakuan  diulang 4 kali. Parameter utama yang diamati adalah retensi protein dan retensi energi pada air tawar bawal. Parameter yang diukur didukung oleh parameter kualitas air. Analisis data menggunakan Analisis Varian (ANOVA) dan untuk menentukan perlakuan terbaik digunakan Duncan's multiple range test. Hasil penelitian menunjukkan perbedaan yang signifikan (p <0,05) dalam retensi protein dan energi adalah daging ikan bawal air tawar. Retensi protein dan retensi energi dalam pengobatan P1 (0,6% lisin), P2 (1,2% lisin), P3 (2,4% lisin) dan P4 (4,8% lisin) berbeda secara signifikan dengan perlakuan P0 (kontrol). Kualitas air selama 40 hari perlakuan ditetapkan pada suhu 27-300 C, pH 7,5-8,5, amonia 4 mg / l dan oksigen terlarut 4 mg / l.                                                                 AbstractAmino acids are the smallest components that compose proteins. A number of amino acids will be conducted to one another through the intermediary of peptide bonds to form proteins. Amino acids have divided into two; those are essential amino acids and non-essential amino acids. The essential amino acids are amino acids that can not be synthesized by the body of fish; therefore the essential amino acids must be in feed. Lysine is one of the ten essentials amino acids , the function of lysine are for the growth and repair body tissues. This research was aimed to determine the effect of lysine in commercial feed on protein retention and energy retention of freshwater Bawal.The method used is experiment with a completely randomized design as an experimental design. The treatment used is different lysine levels , namely P0 ( 0 % ) , P1 ( 0.6 % ) , P2 ( 1.2 % ) , P3 ( 2.4 % ) , P4 (4.8 % ) and treatment was repeated 4 times. The main parameters were observed protein retention and energy retention on Bawal fresh water. Parameters measured were supported by water quality parameters. Analysis of the data using Analysis of Varian ( ANOVA ) and to determine the best treatment used Duncan 's multiple range test. The results showed the significant differences ( p < 0.05 ) in protein retention and energy were freshwater pomfret fish meat. Retention of protein and energy retention in treatment P1 ( 0.6 % lysine ) , P2 ( 1.2 % lysine ) , P3 ( 2.4 % lysine ) and P4 ( 4.8 % lysine ) was significantly different with treatment P0 ( control ). The quality of water for 40 days treatment was set to temperature 27-300 C, pH 7.5-8.5, ammonia 4 mg/l and dissolved oxygen 4 mg/l.

The health benefits in the description and observation of quantitative contents of quality parameters present or contained in any water source cannot be underestimated as they determine selection of best choice from available water sources for different intended uses as well as resource consumption. It also helps to compare the observed quantity of the quality with the acceptable standards or limits to get desired results. Physical parameters like pH, temperature, electrical conductivity (EC) and total dissolved solids (TDS) among others are determined by present of other chemical properties like Cations (Mg2+, Ca2+, Na+, etc), Anions (Cl-, NO3-, SO42+, etc), heavy metals and other dissolved materials during the course of its formation in different proportions and amounts. This study observed EC and TDS of 20 selected boreholes as two close and correlated water quality parameters as well as two of the major water quality parameters that account for overall quality of any water source, despite their different quantitative contents and physical features, they are likely determined by the same set of cations and anions with similar constraint equations. In contrast to linear programming, multiple criteria optimization models were fitted for EC and TDS using Response Surface Methodology via desirability techniques, optimal values obtained in this case measured against several criteria are found to lie between acceptable standards limits for drinking water, other numerical values and descriptive features in the final results reflect that the response equations obtained were well fitted.

The sublittoral forests formed by the fucoid algae Cystoseira spp. are important juvenile habitats for many Mediterranean fish species. However, the spatial variability of juvenile fish assemblages within the forests and the potential environmental drivers, such as depth and habitat complexity, remain poorly understood. We estimated densities, sizes and behaviours of juvenile fish assemblages in subtidal (0-15 meters) Cystoseira brachycarpa var. balearica forests in north Minorca Island (North-western Mediterranean Sea) over two consecutive autumns (2012 and 2013). Depth and forest complexity, here measured as canopy volume, had both a significant and independent effect on the juvenile fish assemblages in terms of species abundance composition and body size. Assemblages found in the shallowest depth range (3-4m) were characterized by greater densities of the ornate wrasse Thalassoma pavo, while those deeper (10-12m) had higher densities of the rainbow wrasse Coris julis, independently of its size composition. Juveniles of both species were more abundant in less complex forests; conversely juveniles of wrasses of the genus Symphodus were more abundant in more complex forests. The smallest sizes of T. pavo occurred in the most complex forests. On the other hand, our results demonstrated that juvenile fish behaviours were unrelated to the complexity of the Cystoseira forests but mainly related to the body length. The effects of body length on behaviour were however species dependent. Cryptic and transitory behaviours were mostly observed in the smallest and largest juveniles of T. pavo and C. julis, respectively, while the behaviour of Symphodus spp. was unrelated to their body length. Our study emphasises the importance of preserving healthy Cystoseira forests and their intrinsic patchy nature, as this habitat, with its mosaic of different complexity degrees and bathymetrical variability, enable the presence of different fish species at various life stages.

The dynamics of publication activities devoted to the climbing perch from 1969 to 2018 is analyzed. It is shown that sharp increases in the number of publications at the turn of the millennium coincide with changes in international and national strategies for tropical fish aquaculture, focusing on cultivation of fast-growing native fish species and small farms support. These programs have led to a surge in applied research and publications on the climbing perch, as one of the most promising species. Unfortunately, some of these papers have been published in journals that are unreliable according to the criteria of contemporary science and contain controversial conclusions. Certain consequences of these trends are noted and challenges outlined.
