Influence of three cage shapes viz (i) rectangular ii) square, and (iii) circular on growth and production of Mystus cavasius (local name: gulsha) was studied in earthen pond conditions for a period of 120 days. Each of nine cages, which were made of polyethylene nets, had same internal area (1.80 m3) and stocked with M. cavasius fry at the rate of 300 m-3, following a completely randomized design. Fishes were fed with a commercial floating pellet feed (Mega 002) initially at the rate of 25% of average body weight, with a gradual reduction to 8%. Significantly higher (P<0.05) average weight gain (AWG) of 13.49 ± 0.14 g, with specific growth rate (SGR) of 1.87% day-1, and the survival rate of 89.41% were recorded for gulsha reared in the circular cage compared to the other shapes. Rectangular and square cages resulted in a similar (P>0.05) AWG of 10.29 ± 0.10 and 10.43 ± 0.25 g with survival rate of 80 and 83.61%, respectively. A significantly higher (P<0.05) average total production of 4.05 ± 0.21 kg/m3 was obtained with circular cage compared to a similar production of 2.72 ± 0.28 and 3.08 ±0.29 kg/m3 (P>0.05) in rectangular and square cages, respectively. In case of lengthweight relationship (LWR), the coefficient of determination values (r2) was 0.86, 0.90, and 0.85 in square, circular and rectangular cages, respectively indicating a good linear regression between length and weight in circular cages than square and rectangular cages. Taken together, these results indicate that circular cage is the best for growth, survival and production of gulsha culture in pond condition. Ann. Bangladesh Agric. (2020) 24(2): 59-68

Trout larvae of average weight of 0.08391 to 0.08907 gm were nursed in 12 floating net cages set in a circular tank. The larvae were fed with 4 different diets- Diet 1 (normal diet), Diet 2 (normal diet with buff liver), Diet 3 (normal diet with chicken liver) and Diet 4 (normal diet with mutton liver). The experiment was conducted at completely randomized design (CRD) with three replications for each diet. Body weight, total length and condition factor of larvae did not show significantly variation at different test diets. The specific growth rate was recorded 3.043% per day which was highest in test diet 3. The highest Food Conversion Ratio (FCR) i.e., 2.8768 was recorded in diet 4. Physico-chemical parameters and the survival rate were also recorded. The correlation coefficient of length and weight relationship was highest (0.972) in diet 3.

Aim of study: To evaluate the effects of increasing NaCl levels on the zootechnical performance of pacu fingerling. Area of study: The experiments were conducted at the Aquatic Organism Production and Reproduction Systems Laboratory belonging to the Federal University of Paraná (UFPR), in the Palotina Sector, Paraná Estate, Brazil. Material and methods: Seven hundred and fifty fingerlings with an average weight of 3.41 ± 0.09 g were distributed in circular boxes, in a completely randomized design consisting of six treatments and five replications. Treatments comprised soybean- and maize-based diets containing increasing levels of NaCl (0.00, 0.25, 0.50, 0.75, 1.00 and 1.25%). The experiments were conducted for 50 days. At the end of the experimental period the fish were fasted for 24 hours, anesthetized, weighed and measured to calculate zootechnical performances. Performance data were subjected to an analysis of variance followed by Tukey’s test when significant differences were found between the means (p<0.05). Main results: The influence (p<0.05) of dietary NaCl levels on final weight, feed intake, apparent feed conversion, specific growth rate, average weight gain, clean trunk production, head carcass yield, headless carcass yield, feed intake and survival was assessed. The results indicate that non-salt treated fingerlings along with the 0.25% salt inclusion treatment led to better feed use, as evidenced by apparent feed conversions of 1.64 and 2.02, respectively. Research highlights: The inclusion of NaCl in pacu fingerling soybean and maize-based diets is not recommended.

This research was conducted to determine the effect of giving different lime on the survival rate and growth of snack head seeds. This writing uses a completely randomized design (CRD) with 4 treatments and 3 replications. The hypothesis being tested was that the application of the limed lime had no significant effect on survival rate, the growth of snack head seed and the specific growth rate and lime administration differed significantly in feed conversion. The study was conducted at the Wet Aquaculture Laboratory, Palangka Raya University starting from February 3 - March 3, 2020. The results showed that the administration of different lime had no significant effect on survival rate, growth and specific growth rates but had a significant effect on feed conversion. The best survival rate of snack head seeds is in treatment D (250 g) that is equal to 57.73%, the best weight growth is in treatment C (200 G) that is equal to 3.16 grams, the best length growth is in treatment D (250 g) that is 2.57 cm, the best specific growth rate is in treatment D (250 g) which is 2.92% / day, and the best feed conversion value is in treatment D (250 g) which is 1.47%. Water quality such as temperature, acidity (pH) and dissolved oxygen (DO) are still in the normal range.

One of the technologies to keep the water quality remains optimal ias a recirculation system. This research is aimed to determine the influence of denisity of catfish (Clarias gariepinus) on the recirculation system. Fish test used is catfish fry the age of 2 weeks with average weight 0.58 g and an average length of 2.7 cm as much as 10,000 fish. The experimental research used completely randomized design with 4 treatments and 3 replications. The treatments were A (20 fish/liter of water), B (30 fish/liter of water), C (40 fish/liter of water) and D (50 fish/liter of water). The survival rate, the feed efficiency, and water quality has been observed. The results of research showed that the survival rate and the feed efficiency were significantly different (P<0.05). The highest survival rate in this research was in the treatment A (20 fish/liter of water) that was 70.5%. The stocking density of catfish fry of 20 fish/liter of water can be used as basis for  the maintenance of catfish fry for reach the optimal survival rate. Key words: Catfish, survival rate, feed efficiency, recirculation
