Feeding experiment was conducted for 45 days to evaluate the effects of salinity on the feeding efficiencies, growth performances and survival rate of 11th strain of tilapia, Oreochromis niloticus (GIFU) in laboratory condition. Three rectangular glass tanks were used for the experiment with different level of salinity (0 as control; 8ppt and 10ppt (ppt means parts per thousand, g/l) as treatment 1 and treatment 2 respectively) using two replicates for each level of salinity. Seventy-five fingerlings were stocked in the tanks. The investigation was conducted at one feeding rate (3% of body weight) which has given twice a day in a 1 X 2 factorial experiment. Average food conversion ratios (FCR) were 2.66 ± 0.04, 1.76 ± 0.04 and 1.69 ± 0.07 in controls, T1, and T2 respectively. Average protein efficiency ratios (PER) were 0.63 ± 0.04, 1.31 ± 0.01 and 1.68 ± 0.02 in control, T1, and T2 respectively. The feed efficiency (FE) were 35.22 ± 1.54, 32.45 ± 1.22, and 31.54 ± 1.85 in control, T1 and T2 and specific growth rate (SGR) were 0.42 ± 0.03 %/d in control, 0.99 ± 0.03 %/d in T1 and 1.34 ± 0.09 %/d in T2 respectively. The net weight gain of fish in T2 (39.12 ± 0.17 g) and T1 (31.1 ± 0.02 g) were significantly higher than that of control (30.00 ± 0.21 g). The net length gain of fish in T2 (12.12 ± 0.03 cm) and T1 (10.5 ± 0.02 cm) were significantly higher than that of control (9.5 ± 0.04 cm). The survival rates were 85%, 100% and 100% in C, T1 and T2 respectively. The proximate composition of fishes, water quality parameter, feeding efficiencies and growth performances were better in T2 than that of T1 and C. The best growth was found from T2 (salinity 10 ppt) and lower growth was found from control (salinity 0 ppt) in case of GIFU. The present study revealed that GIFU can tolerate a wide range of salinity and shown better growth and survival rate.

Proper stocking density on larval rearing of barred loach (Nemacheilus fasciatus Valenciennes, 1846) is very important in terms of obtaining the best growth and survival rate. This study was aimed to observe the growth and survival rate of barred loach subjected to different larval stocking density. Fish larvae were obtained by artificial spawning from in aquarium. Larvae were stocked on aquariums (50 × 40 × 30 cm) with three stocking density treatments (5, 10, and 15 individuals/L) and three replications. The experimental fish larvae were fed by Artemia and commercial feed (crude protein content: 30%) and feeding frequency twice per day (ad libitum). The length and weight were reassured every 10 days during 70 days of rearing period. Temperature, pH, and dissolved oxygen were measured at each treatment. Data obtained from measurements were analysed to assess the length gain, weight gain, specific growth rate (SGR), biomass gain, and survival rate. The results showed length gain of 3.35 ± 0.01, 2.94 ± 0.10, and 2.82 ± 0.15 cm and weight gain of 0.573 ± 0.023, 0.436 ± 0.018, and 0.417 ± 0.043 g in larval stocking density of 5, 10 and 15 individuals/L, respectively. Specific growth rates and biomass growth were of 6.22 ± 0.41, 5.93 ± 0.21, and 5.68 ± 0.41 %/day and 94.04 ± 5.39, 146.80 ± 3.81, and 167.24 ± 17.48 g in larval stocking density of 5, 10 and 15 individuals/L, respectively. Meanwhile, the survival rates obtained in this study were 89.13 ± 7.25, 93.13 ± 5.13, and 76.50 ± 3.54 % in larval stocking density of 5, 10 and 15 individuals/L, respectively. Increased stocking density has a negative impact on the growth and survival rate of barred loach.
