A research study was conducted to investigate the culture possibility of fresh water catfish Pangasius pangasius with formulated feed in natural ponds. The stocking density was chosen as 8000 fry/ha with an initial weight of 42.57±2.51 g. The formulated feed contained 45% fishmeal, 30% mustard oil cake, 15% wheat bran and 10% rice bran to supply 40.48% protein in feed. The growth of Pangasius pangasius in terms of net weight gain was found as 266.49g, which was statistically significant (p<0.05). The food conversion ratio (FCR) observed during this research study was high (7.58). There was no variation in the biochemical composition of the fish as a result of such culture technique and experimental conditions. The whole experiment was conducted for a period of 10 months. Production of fish was found to be 2.13 tones/ha using this formulated feed. Keywords: Culture; Pangasius pangasius; Formulated feed; Pond DOI: 10.3329/jbau.v6i2.4837 J. Bangladesh Agril.

Investigation was carried out from June to August 2009. A total of 40 fish farmers were selected from northwest two upazila namely Debigonj (n=20) and Boda (n=20) where both men and women were targeted. Focus group discussion (FGD) and cross-check interview were conducted to get an overview on carp farming. From 1991-1995, 1996-2000 and after 2000; 17.5%, 45% and 37.5% of fish farmers started carp farming respectively. Average 77.5% of farmers acquired training from NFEP project while 10% of them from government officials. There were 55% seasonal and 45% perennial ponds with average pond size 0.09 ha. After phase out of NFEP project, 92.5% of fish farmers followed polyculture systems, while only 7.5% of them followed monoculture ones. Farmers did not use any lime, organic and inorganic fertilizers in their ponds before association with NFEP project. They used lime, cow dung, urea and T.S.P during pond preparation at the rate of 247, 2562.68, 46.36 and 27.29 kg.ha-1.y-1 respectively where stocking density at the rate of 10,775 fry.ha-1 after phase out of the project. Feeding was at the rate of 3-5% body weight.fish-1.day-1. Rice bran, wheat bran and mustard oil cake used at the rate of 1920, 220 and 110 kg.ha-1.y-1 respectively by 85% of fish farmers but 15% of them did not used any feed. Before NFEP project, average pond production was 408.55 kg.ha-1 but after phase out the project, fish production was 2,861.08 kg.ha-1. Peak culture and harvesting period lied from April to December and from November to January. Average 92.5% of farmers improved their livelihood through carp farming. Fish farming was affected due to low water depth and drought conditions. Keywords: NFEP; Fish farming parameters; Pond production; Livelihood approach DOI: 10.3329/jbau.v8i2.7942 J. Bangladesh Agril.

Brood Fish

This study represented a survey report on present status of management of carp brood fish. The survey was conducted with 40 hatcheries at Chacrha in Jessore from June to November, 2012. Production of brood fish was found to depend on the combined interaction between feed and culture technique. Some information showed that brood fish selection for induced breeding was done on the basis of their experience. Pond preparation was carried out properly but stocking density of brood fish was quite high and water quality was not maintained properly. Negative selection of brood fish was done in few hatcheries aiming at reducing the cost for collecting or purchasing good quality broods. The sources of brood fish were mainly own and other sources were Halda River, Padma River, Govertment brood bank and World Fish Center. Feed used for brood carp fish were mainly rice bran (34.57%), mustard oil cake (21.78%), vitamin and mineral premix (0.8%), wheat flour (8.64%), fish meal (8.64%) and soya bean flour (10.37%), maize flour (6.91%), rice ( 6.91%), di-calcium (1.73%), salt (0.34%) and antioxidant (0.04%) . Nutritional composition of feed was mainly crude protein (30-40%), crude lipid (10-12%), carbohydrate (20-30%). Protein percentage of feed always tried to keep 26% even though it was varied due to the other feed ingredients. Fertilizer such as Triple super phosphate (0.73 kg/dec), urea (0.25 kg/dec), potash (1.5 kg/decl), cowdung (5.19 kg/dec), poultry offal (1.9 kg/dec) and Murite of potash (0.13 kg/dec) were used. Scientific brood and hatchery management could be a good approach to attain the main purpose of aquaculture. DOI: http://dx.doi.org/10.3329/jbau.v11i2.19939 J. Bangladesh Agril.

The growth performance of Macrobrachium rosenbergii (Deman,1879) under different stocking densities was conducted under three treatments each with three replications namely T1: 10m-2 T2: 12m-2; T3: 14m-2 for a period of six months from April to September, 2012 in 9 experimental ponds in Terokhada Upazilla under Khulna district. Supplementary feeds (mustard oil cake (20%), wheat bran (20%), rice bran (20%), fish meal (25%) and maize bran(15%) were used for all stocked individual. Water quality parameters and growth performances were monitored monthly. The mean values of water temperature, transparency, dissolve O2, pH and salinity were varied from 28.88 ± 0.161±oC(T2) to 31.32 ± 0.97±oC (T1), 29.73 ± 0.34cm(T1) to 32.70 ± 0.28cm(T2), 5.33 ± 0.184mg-1(T3) to 6.17 ± 0.13 mg-1 (T1), 6.52 ± 0.205(T2)to 6.79 ± 0.18(T1) and 13.75 ± 0.16(T2) to 15.22 ± 0.20(T1). The weight gain of Macrobrachium rosenbergii were 59.79± 0.15 g(T1), 50.86±0.14g(T2),48.78±0.12g(T3).The survival rate (%) of M. rosenbergii were 75.02±0.577 (T1), 66.66±0.88 (T2), 61.01±0.577(T3) respectively. Yields (Kg ha-1 6 month-1) Macrobrachium rosenbergii were 2302.04kg (T1), 1768.52 kg (T2), 1393.808 kg (T3) respectively. Total cost 656000 ± 17480 Tk ha-1 (T1), 596120 ± 4520 Tk ha-1 (T2) and 549100 ± 9440 Tk ha-1 (T3) respectively and total return of different treatments T1, T2 and T3 were 1492400 ± 12800 Tk ha-1, 1078200 ± 11930 Tk ha-1 and 806480 ± 9190 Tk ha-1 respectively.

An experimental culture trial of juveniles of mutton snapper Lutjanus analis was conducted in order to evaluate the growth potential of the species and its adaptability to culture conditions. The juveniles (N = 127) with an initial weight ranging between 125 and 178 g were held at a stocking density of 15.9 fish/m3 in a floating cage and fed on a commercial artificial diet of 45% protein for a period of 1 to 8 days. Results showed an individual daily weight increase of 3.16 g/ day and a specific growth rate of t .06 %/ day. Although, the food conversion ratio obtained with the artificial diet was high and inadequate (TCA = 3.53). During the culture period all fish showed great tolerance to handling stress and to water quality conditions in the cage (O2 = 6.2-7.1 mg/L; Temp = 27.9-30.5 oC; Sal = 31-37). Overall survival was 97.6%. It is concluded that the mutton snapper has very important advantages for its culture like fast growth and tolerance to captivity conditions.

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

Cannibalism occurs in many cultured fish species, especially at the larval and juvenile stages of piscivorous taxa. In farmed percid species, such as pikeperch (Sander lucioperca), intra-cohort cannibalism is a major issue inducing significant losses of the initial stocking density during the first weeks of rearing. Therefore, the present study was designed to investigate the effects of perch larvae (Perca fluviatilis) as live prey on growth, survival and cannibalism in pikeperch larvae under experimental conditions. Additionally, zootechnical and behavioural variables linked to aggressiveness (S postures, attacks, bites and ingestion), and group structures were considered. The survival rate was not different between the two groups (72% with prey vs. 69% without prey), but the cannibalism rate was higher in the group with the prey (28% vs. 10%). The means of final weight and length of pikeperch larvae were higher in the group fed with perch larvae, but size heterogeneity measured by the coefficients of variation for these two parameters did not differ. The specific growth rate was higher in the group fed with perch larvae, but there was no difference between the two groups concerning Fulton’s condition factor. Among all the behavioural variables (aggressiveness, group structure), none differed between the two groups.

This study was conducted to investigate and compare the growth performance of four Tilapia strains in hapa nursing with the aim to find out the best strain of tilapia. The research was conducted by four treatments with five replicates each. The tilapia fry were collected from, BFRI source from BFRI HQ, Mymensingh stocked in Treatment-1; unknown source from Hi-Tech Tilapia Hatchery Dagoanbhuiya, Feni in Treatment-2, Philipine strain from Green Field Tilapia Hatchery, Laxmipur in Treatment-3 and fry from Breeding Cohort, Sonar Bangla Hatchery, Bamna, Barguna in Treatment-4. The Individual stocking weight (g) of fry was average 0.01g. The fries were stocked in 12 hapa at same stocking density of 1200 fish/m2. Each of the hapa was 2m × 1m × 1m size and fixed in an earthen ponds. Supplementary feed with 31.29% of protein level consisting of rice bran (25%), mustard oil cake (15%), wheat flour (30%) and fish meal (30%) was given at the rate of 40% of their body weight per day manually, four times a day at the beginning of the experimental period and reduced to 25% of their body weight and continued up to harvesting period. The results showed that fry of Treatment-4 strain was the best strain and had significantly (p < 0.05) higher final mean body weight (FMBW), mean body weight gain (MBWG), specific growth rate (SGR) (9.75%), gross yield (GY) (2.13) and Net yield (NY) (2.12) than the Treatment-1 , Treatment-2 strains and Treatemnt-3 strain. Treatment-4 strain had the fastest growth rate, whereas the lowest performing strain was that from Treatment-2. We also analyzed survival rate of the fish from stocking to harvest, survival rate was highest in Treatment-4 strain (80%) where lowest is Treatment-3. Treatment-4 stain also showed the best feed conversion ratio (FCR) 1.62 than others. Considering the overall performance it can be concluded that tilapia strain collected from Breeding Cohort source is best among the four strains. However, further research may still be needed to compare more strains from different water body to evaluate the genetic potential for Tilapia.International Journal of Natural Sciences (2015), 5(2) 98-106
