“…Santhosh and Singh (2007) suggested that 0.1 to 4.0 mg l -1 concentration is the favourable range of nitrate for fish culture. Results of our study are in accordance with the earlier findings of Atse et al (2009) who found that the nitrate range of 0.12 to 0.20 mg l -l is safe for fish production in RAS. During the experimental period, phosphate was found in the range of 0.02 -0.08 mg l -l .…”

Production performance of the Indian major carp, catla Catla catla (Hamilton, 1822) was examined at different water flow rates in recirculatory aquaculture system (RAS), in Tarai region of Uttarakhand. The experiment was conducted in 12 FRP tanks of RAS with sand filter and UV filters, with four treatments and three replicates for each treatment viz., control, T0 (83 l h-1 or one time in two days); T1 (667 l h-1 or 4 times in a day); T2 (333 l h-1 or 2 times in a day) and T3 (167 l h-1 one time in a day) from November 2015 to April 2016. The fingerlings of catla having uniform body weight (10.00±0.6 g) were stocked randomly in all treatment groups at the rate of 25 no.m-3. Physical properties of water such as water temperature, electrical conductivity and total dissolved solids were analysed weekly throughout the experimental period and ranged from 15.8 to 27.8°C, 271 to 384.3 µS cm-1 and 216.3 to 274 mg l-l, respectively. Water parameters such as pH, dissolve oxygen, free carbon dioxide, alkalinity, hardness, ammonia, nitrate and phosphate were also analysed which varied from 7.2 to 8.4, 5.4 to 7.9 mg l-l, 1.8 to 3 mg l-l, 118 to 167.3 mg l-l, 133.3 to 241.6 mg l-l, 0.02 to 0.08 mg l-l, 0.11 to 0.42 mg l-l and 0.02 to 0.08 mg l-l respectively. The best food conversion ratio (FCR) was recorded in T0 (1.61) followed by T3 (1.65), T1 (1.70) and T2 (1.81). Highest specific growth rate (SGR) was recorded in T2 (0.88%), followed by T1 (0.86%), T3 (0.85%) and T0 (0.84%). The best protein efficiency ratio (PER) was recorded in T2 (2.31) followed by T3 (2.54), T1 (2.56) and T0 (2.62). Among different treatment groups, the survival rate of catla varied from 78 in T0 to 83% in T1.. Significantly higher (p<0.05) growth performance of catla was recorded in T2 as compared to other tanks.

“…The lipid content did not affect the survival rate. The results recorded in late survival experience are similar to those reported by [11,12,32] from 67.77 to 70.15 % with larvae sorted once and three times a week with the same species and the same provisions breeding. Food distributed allowed more or less homogeneous growth of the larvae.…”

This study showed clearly the effect of adding palm oil to the diet of farmed fish to replace marine animal oils. For this purpose, four foods based on maggot flour at 35% protein with the incorporation of palm oil, at different levels at 0, 2, 5 and 10% were tested in the to assess their impact on the improved growth performance, food utilization, survival rate and biochemical composition of Heterobranchus longifilis larvae Four experimental diets were formulated based on the maggot meal as the main protein source. These diets were formulated at 35 % protein levels with maggot meal and maize flour as the major ingredients containing different concentrations of palm oil levels at 0, 2, 5, and 10 %. This study was carried out in the reproduction laboratory, at Oceanological Research Center, Abidjan, Côte d’Ivoire, between the periods of September to November 2022. The diets were offered to the larvae (average initial weight 0.004 ± 0.001 g) three times a day ad libitum for 49 days. At the end of rearing, the results showed that the different experimental foods distributed did not influence the quality of the rearing environment. The best growth was obtained with the larvae subjected to diet containing 2% palm oil with a final average weight of 3.21 g and a conversion index of 1.63. Beyond this rate, larval growth decreases. Survival rates vary from 70 to 73 %. The conversion ratios are not significantly different and ranged between 1.63 and 2.3. On the biochemical larvae submitted to diet containing 10 % of palm oil had body lipid content (2 %) and high ash rich. As against a gain of protein is observed with larvae submitted to diets containing 2 % palm oil reflects an effect of protein. From the present results, diet containing 2 % crude palm oil is considered optimal for Heterobranchus longifilis larvae.

The effects of substitution dietary fish protein by soybean protein on growth, survival, biochemical composition and mineral composition of juvenile Heterobranchus longifilis, Sarotherodon melanotheron and Oreochromis niloticus were evaluated. Three diets were formulated to be isonitrogenous (35% crude protein) by substituting fish meal for soybean meal at levels of 0 (FM), 25 (SBM25) and 50% (SBM50). Diets were fed to triplicate groups of each species at ratio of 5% body weight. At the end of the study period, final body weight (FBW), final body length (FBL), specific growth rate (SGR) and protein efficiency ratio (PER) decreased with an increasing dietary soybean protein level in H. longifilis. Survival rate (SR) was 1.5 times lower in juvenile catfish fed SBM50 (29.3%) than FM-and SBM25-fed fish (44%). S. melanotheron fed all three diets had no significant difference in FBW, FBL, SGR, SR, FCR, PER or production time. In O. niloticus, SR, FCR and PER were not affected by dietary protein substitution level. However, FBW, FBL and SGR increased with an increasing dietary soybean protein level. The production time generally showed a decline at lower protein substitution levels. The production cost was significantly lower in fish fed SBM50. Proximate composition analysis indicated that the carcass moisture in the three species and carcass protein content in H. longifilis and O. niloticus were not affected by dietary protein source. In S. melanotheron, carcass protein content showed a decline in fish fed SBM50. Carcass lipid, ash and gross energy levels in these species were also significantly affected by dietary protein sources. Carcass calcium and phosphorus concentrations in fish were significantly reduced with a high inclusion of dietary soybean meal. The results of this study indicated that fish meal can be replaced with soybean meal up to 50% level in diets for Tilapia S. melanotheron without adverse effects on growth, nutrient utilization or nitrogen balance.
