Murshidabad district is the highest jute producer district in West Bengal where maximum numbers of ponds beels, canals and irrigational channels are being used for jute retting from July to September and after retting, water bodies remain uncultured. But few farmer’s, they were culture traditionally with IMC and exotic carps and getting very low yield (3.66q ha-1yr-1). In that condition Murshidabad KVK has designed one OFT trails having three treatments, Farmer’s Practice (FP), Technology Option-I (TO-I) and Technology Option-II (TO-II) on air-breathing fish pangas (Pangasius pangasius) and conducted in farmers’ field for three years. To find out the suitable fish species, observed water parameters (pH, DO mg L-1), stocking density (nos./ha), length (cm), weight (g), survival rate (%), yield (q ha-1yr-1), cost of culture (Rs. ha-1yr-1) gross return (Rs. ha-1yr-1), net return (Rs. ha-1yr-1), BC ratio and disease incidence etc. The effect of water pH and DO (mg L-1) in post jute retting pond and fish stocking pond indicate, there were a statistically significant difference between three treatments at (p <.05). Stocking density in three treatments were 15000 nos. ha-1 (IMC and exotic carps), 11250 nos. ha-1 and 15000 nos. ha-1 (pangas, size 2.5”) . In this trial it was observed that the mean (SD) initial length (cm), initial weight (g) and final length (cm) were not statistically significant at p >.05 but in case of final weight (g) and weight gain (g) there were statistically significant at p<.05. The survival rate (%) was lowest in FP (35.04±4.51) and highest in TO-I (67.55±17.50) and not statistically significant (p >.05). The mean (SD) yield (q ha-1yr-1) was high statistically significant difference found among three treatments (p <001). The average net profits were Rs.65680.0, Rs. 223841.0 and Rs. 337551.0 ha-1 yr-1. in FP, TO-I and TO-II, respectively. The highest mean B:C ratio was 2.44 in TO-II. With the all concerned it was observed TO-II gives the best result among these three treatments in these three years trials.

This study was carried out to evaluate the growth response of guppy Poecilia reticulata to different dietary protein levels. A total of 72 fry of guppy fish of an initial body weight 0.365± 0.01g were distributed randomly into 60 L aquaria at the density rate of 0.05 g/L. Fish were fed to satiation twice daily for eight weeks with diets containing different dietary protein levels (20%, 30%, or 40%.). The survival rate of guppy was unaffected by increasing dietary protein levels. At the end of the experiment, weight gains (g) ranging from 1.93 to 3.55 were obtained corresponding to 20% and 40% crude protein respectively. The growth performance and feeding efficiencies were significantly improved (P < 0.05) by increasing dietary protein levels. However, no significant difference (P > 0.05) was observed in the specific growth rate of fish that were fed 20% and 30% dietary protein levels. The value of the condition factor was significantly high in fish fed at 40% dietary protein. It can be concluded that a 40% dietary protein level is recommended for guppy fish.

Attempt has been taken to develop intensive tank culture technique providing natural environment for Stinging catfish (Heteropneustes fossilis) inside tank to increase survival rate as well as production. The experiment was conducted for a period of 150 days in two tanks (T1 and T2) of 300 m2. Fish fries with a mean weight and length ranged from 1.02 to 2.2 g and 2.7 to 3.5 cm were stocked in T1 and T2, respectively. Stocking density of fingerlings were 1, 25,000 and 1, 50,000 per Ha in T1 and T2, respectively. Commercial pelleted feed was supplied to tank reared fish twice daily at a rate of 3-10% of body weight per day and later feeding rate was adjusted based on body weight by sampling. Important water quality parameters (temperature, DO, pH, transparency, ammonia and nitrate) were recorded weekly throughout the culture period. Survival rate was 87% and 84% in T1 and T2, respectively. Mean final weight were 41.73 ± 2.09g and 40.6 ± 0.90 g in T1 and T2, respectively. Length-weight relationship indicates that the growth rate was always higher in T1 followed by T2. Results showed that net yield was relatively higher in T2 (5115.35 ± 113.13 Kg/ha) than T1 (4537.12 ± 227.4 Kg/ha). In case of production, there was significant difference (p < 0.05) between two treatments. This experiment demonstrated the potential of H. fossilis production through new technique of tank culture system. However, more research is needed using local feed ingredients with higher stocking density. Bangladesh J. Zool. 47(1): 107-119, 2019

Dietary protein and energy requirements of juvenile freshwater angelfish (Pterophyllum scalare) were evaluated. A 3 × 2 factorial design was used, with three dietary crude protein levels being tested (26, 30, and 34% of CP) combined with two digestible energy levels (3,100 and 3,300 kcal DE/kg of diet) in three replicates. Juveniles averaging 2.33 ± 0.26 g were reared in a 25L-aquarium with controlled temperature (26 ± 1ºC), biological filter and stocking density of six fish/aquarium. Fish were fed ad libitum at 09:00 a.m., 2:00 p.m. and 4:30 p.m. The following performance parameters were evaluated: final weight, final length, weight gain, feed intake, feed conversion ratio, specific growth rate, protein efficiency ratio and condition factor. Fish fed diets with 26% CP showed greater protein efficiency values when compared to those fed diets with 34% CP. Diets with 26% of CP and 3100 kcal DE/kg could meet the nutritional requirements of juvenile freshwater angelfish.

Digestive Enzyme Activities

Pengba, Osteobrama belangeri (Valenciennes, 1844) is considered as one of the candidate species for diversification of aquaculture. However, only scanty information is available on its nutrient requirements. Hence, the present study was conducted on growth and digestive enzyme activities of pengba fry in response to different dietary protein levels. Six semi-purified isocaloric diets were formulated with different levels of protein at 5% increments (25, 30, 35, 40, 45 and 50%) and fed to different groups of pengba fry for a period of 60 days. Survival of fish was significantly influenced by different protein levels (p<0.05). The highest weight gain% and specific growth rate (4.17% day-1) was obtained at 45% protein level which thereafter declined. The best feed conversion ratio (1.46) was observed at 45% protein level and the highest protein efficiency ratio (2.14) was obtained at 25% protein levelwith significant difference (p<0.05). The crude protein content of fish was significantly affected by dietary protein levels (p<0.05) and highest was recorded at 45% protein diet. Moisture, ether extract and ash content did not show significant (p>0.05) variation among dietary treatments. The activity of proteolytic enzymes (proteases, typsin and chymotrypsin) and acid phosphatase were signicantly (p<0.05) enhanced by dietary protein levels up to 45%, which were found to decline thereafter. Amylase activity was significantly decreased as protein levels increased in the diet. Lipase and alkaline phosphatase activities were not influenced by dietary protein levels. In the present study, penbga fry fed with 45% protein diet, showed the best growth performance and highest digestive enzyme activities. The activity of digestive enzymes in the gut clearly demonstrated that the proteolytic enzymes are activated in response to dietary protein utilisation and also revealed that pengba fry may require high protein (45%) diet for better growth and survival. Second order polynomial regression analysis revealed that the maximum protein requirement of pengba fry was 45.1% (r2 = 0.90). The findings of the study is expected to have significant implications for feed development for pengba aquaculture.

Vaname shrimp is one of the fishery products that are expected to produce foreign exchange for the country besides tiger shrimp.  One factor that can affect the growth and the production of vaname shrimp culture is dense stocking. The research was conducted in October-December 2016 at the Balai Benih Ikan Pantai (BBIP) Ghonebalano, aims to determine the effect of different stocking density on the growth and survival of vaname shrimp.  The research was using Completely Randomized Design with three treatment levels of density, i.e. treatment A = 10 individuals per container, treatment B = 15 individuals per container and treatment C = 20 individuals per container and three replications.  The results showed that the highest growth was obtained in treatment A which was 1,563 g/individuals, compared with treatment B (1.189 g/individuals) and C treatment (0.834 g/individuals).  Survival rate in treatment A is 80.00%, B treatment equal to 75,56% and treatment C equal to 70,00%.  Analysis of variance at 95% confidence level (α0.05) showed that the different density had a significant effect on growth, but had no significant effect on survival rate of the vaname shrimp larvae.

The study was conducted at Kenya Marine Fisheries Research Institute (KMFRI), Sangoro Station, Kenya to compare the growth perfomance of Oreochromis niloticusfry under different protein levels in a biofloc system using weight-length regression models and Fulton`s condition factor (K). Fry of initial mean weight 0.07 ± 0.03 g and length 1.30 ± 0.24 cm were randomly stocked in 18 aquarium tanks with capacity of 50 litres at stocking density of one fish Litre-1. The experiment was set in a greenhouse under controlled temperature and dissolved oxygen conditions using aerators and thermostat heaters. The biofloc used glucose and molasses as carbon sources which were assigned at 22%, 27% and 35% crude protein levels randomly to the aquaria. The fish were fed on their daily ration twice a day at 5% body weight for 14 weeks. Physicochemical parameters were recorded daily using a multiparameter meter and water samples collected before fish sampling for nutrient analysis. A sample of 30 fish per tank were used for taking body weight and total length measurements using an electronic balance and a measuring board respectively. Fry in all treatments exhibited allometric growth with b coefficient varying between 2.54 and 2.66. Average Fultons condition factor ranged between 1.77-1.84 with no significant difference (P>0.05)among the protein levels and the bioflocs. The condition factor showed both carbon sources were suitable for use in the biofloc system and hence replacement of higher protein level (35%) with lower protein level (22%) to reduce the production cost is a feasible application of the biofloc system in fish farming.
