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. Net benefit were 801900 ± 7340 Tk ha-1, 49400± 5930 Tk/ha and 288600 ± 13240 Tk ha-1 in T1, T2, T3 treatments respectively. From these findings, it could be concluded that highest yield was achieved from T1 and lowest in T3 which was significantly (P<0.05) different among the treatments where stocking density were less than other treatments.J.

Increased temperature, decreased water level and reduced culture period of the ponds are considered as major problems for aquaculture promotion in drought prone Barind area of Bangladesh. In order to address these problems, an experiment was conducted to optimize the stocking weight for carp polyculture ponds in Tanore upazila of Rajshahi district, Bangladesh. Three different stocking weights were tested under three treatments (T1: 25±0.12g; T2: 50± 0.15g; and T3: 100±0.19g), each with three replications. Fish growing period (July-December), carp species (C. catla, H. molitrix, A. nobilis, L. rohita and C. mrigala), stocking density (7,410 fishes/ha), lime and ash treatment, fertilization and feeding were same for all the treatments. Water quality (water temperature, dissolved oxygen, transparency, pH and alkalinity) and fish growth parameters were monitored monthly. Mean values of water quality parameters were found within the suitable range for fish culture. Treatment T3 varied more significantly (P<0.05) than that of other treatments for the mean values of final weight, weight gain, specific growth rate, survival rate and yield of fish. Net benefit of carp polyculture was also found significantly (P<0.05) highest with treatment T3.

The study was undertaken to investigate the impacts of water and soil quality parameters, and management practices on shrimp productivity of ghers in three agro-ecological areas of Paikgacha, Shyamnagar and Rampal in the greater Khulna district of Bangladesh. Five ghers of existing culture systems from each of three locations were selected for this study. Findings revealed that water quality parameters including salinity, alkalinity and dissolved oxygen contributed significantly (p<0.05) and positively to shrimp productivity. Phytoplankton production also showed a positive correlation with shrimp productivity. Soil quality parameters including salinity, potassium and calcium content showed positive correlations with shrimp yield. In relation to management practices, stocking density, sources of PL form natural sources and supplementary feeding showed significant (p<0.05) and positive correlations with shrimp productivity. Water exchange also showed a positive correlation with shrimp yield.DOI: http://dx.doi.org/10.3329/pa.v18i2.18170 Progress. Agric. 18(2): 149 - 155, 2007

A six-month-long trial was conducted to assess the supplementation of 30% protein (F2) and 35% protein feed (F3) compared with conventional rice bran+mustard oil cake feeding (F1) on the growth responses of endangered Indian butter catfish, Ompok bimaculatus (pabda) stocked at 15% with 40% catla, 30% rohu and 15% mrigal in polyculture in stocking density of 4000 fingerlings/ha. Water and soil quality parameters were assessed on monthly intervals which showed normal variation among the treatments. The weight of the pabda during harvest was higher in F2 and F3 than F1; as a result, growth rate was higher in F2 and F3 than F1. Survival was highest in F2. The growth of carps was significantly improved in F2 and F3 except for mrigal in F2. Feed conversion ratio significantly lower in F2 and F3 when compared with F1. Benefit-cost ratio was lowest in F3. Overall, the pabda production was increased by 16.2% with F2 and 19.5% with F3. The study concluded that pabda perform better in polyculture with carps when feed supplemented with 30% protein feed.

The research work was conducted to evaluate the effects of stocking density on growth, survival and production of mirror carp (Cyprinus carpio var. specularis) spawn in nursery pond for a period of 35 days. Three treatments differing in stocking density of hatchling viz., T1:172900 individuals/ha, T2:148200 individuals/ha and T3:123500 individuals/ha were employed each having three replicates. Fries were fed same diet in three different treatments consisting of (28.5%) at the rate of 6-10% of body weight. The Physico-chemical characteristics of pond water were measured weekly. The mean values of some water quality parameters such as temperature (°C) were 30.41 ±1.15 (T1), 30.38±1.08 (T2), 30.45±1.10 (T3); transparency (cm) 40.00±0.90 (T1), 39.74±0.51 (T2), 39.93±0.70 (T3); dissolved oxygen (mg/l) 6.79±0.45 (T1), 6.71±0.38 (T2), 7.02±0.29 (T3); pH 7.55±0.18 (T1), 7.67±0.16 (T2), 7.62±0.20 (T3) and alkalinity (mg/l) 116.20±0.64 (T1), 99.36±0.45 (T2), 96.47±0.93 (T3) from 35 days respectively. Except alkalinity no significant value were found for parameters. Sampling was also done weekly. The mean value of final weight (g) was 0.35±0.004 (T1), 0.42±0.008 (T2), 0.59±0.006 (T3). The survival rate of Cyprinus carpio var. specularis was 54.20% (T1), 62.90% (T2) and 74.56% (T3) respectively. The highest survivability was found in T3. The production (kg/ha) of Cyprinus carpio var. specularis was 76.32±4.96 (T1), 77.60±5.19 (T2), 91.04±6.02 (T3) respectively. Significantly (p< 0.05) highest production was found in T3.Asian J. Med.

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.
