“…A balanced ratio of protein and non-protein energy in feed can increase the efficiency of protein metabolism as an energy source and its utilization for fish growth (Sankian et al, 2017;Li et al, 2013;Kim et al, 2017). The optimal ratio of protein to energy, according to Jauralde et al (2021), describes the point of equilibrium between the amount of energy required for maintenance and growth. If an appropriate C:P ratio is obtained, it is possible to reduce the protein level in the feed without impairing fish growth and enhancing the growth response (Carneiro et al, 2020& Aboseif et al, 2022.…”

This study was conducted to evaluate the efficacy of indigofera leaves meal hydrolysate (ILMH) on growth Leptobarbus hoevenii growth. This study employed five dietary treatments with varying levels of ILMH. Cellulase enzymes were used to hydrolyze Indigofera leaf meal, which was then combined with other feed ingredients. Three replicates of feed without ILMH, 10% ILMH, 20% ILMH, 30% ILMH, and 35% ILMH were included in the treatment-examination feed. Average initial fish weight was 1.27±0.01 g, and initial length was 4.28±0.07 cm. Weight observation was also conducted every two weeks. After six weeks of rearing, survival, final biomass, specific growth rate, and feed efficiency were observed. At the beginning and the end of maintenance, temperature, pH, and dissolved oxygen measurements were taken to determine the water's quality. Results that that the utilization of ILMH in L. hoevenii feed could substitute the use of soybean meal for 10-35% of the feed. Among all treatments, 10% ILMH-containing feed resulted in the highest growth and feed efficiency. This treatment had a 100% survival rate, a 1.78±0.05% specific growth rate, and a 53.28 ± 1.59% feed efficiency. According to the findings of this study, the utilization of 10% hydrolysate of indigofera leaf meal in feed was effective in enhancing L. hoevenii’s growth performance.

“…Generally, the dietary protein levels needed for carnivorous and omnivorous species are 40–55% and 35–45% respectively. The feeding rates for fingerlings range from 3.0% to 5.0% (Alvarez‐González et al, 2001; Jauralde et al, 2021; Tan et al, 2012; Tang et al, 2012). High nutrients including high dietary protein levels usually lead to high mesenteric fat, low reproduction ability and fry quality.…”

Nutritional components and feeding strategies are multifarious amongst different producers, whereas they are just designed for fish farming but not suitable for improving the reproductive performance of broodfish. Yellow catfish (Pelteobagrus fulvidraco), an omnivorous species, is one of the important aquaculture fish in China. In order to improve the reproductive performance of female yellow catfish (119.86-134.54 g), four feeding strategies (0.5%, 0.75%, 1% and 1.5% BW/d) and three dietary protein levels (34%, 40% and 46%) were examined, respectively, in the two separate trials. The females with moderate feed restriction (1%) showed significant lower mesenteric fat index (MFI) and higher gonadosomatic index (GSI) than the satiation group (1.5%) and excessive feeding restriction groups (0.5% and 0.75%). Females with high MFI were difficult to be artificially propagated and showed a high mortality rate, whilst the fish at 1.0% feeding rate displayed low mortality rate and high ratios of spawned fish, as well as high percentages of fertilization and hatching. Meanwhile, the offspring of 1.0% feeding rate group showed a low malformation rate and high survival rate. Multiple spawning in the same breeding season are applied in yellow catfish to reduce the number of parent fish and increase the fry production, and gonadal recrudescence after spawning might be affected by different nutrient values including dietary protein levels. In the second trail, female yellow catfish were fed with 34%, 40% and 46% crude protein diet at 1% feeding rate for the second spawning, and the best reproductive and breeding performances were observed in the fish group with 46% crude protein diet. These results demonstrate that 1% feeding rate is optimum for the spawning and reproductive performance of female yellow catfish for the first artificial spawning, and 46% dietary protein group had the best reproductive performances in the second spawning.

The present study successfully combined a stoichiometric bioenergetic approach with an endpoint stochastic model to simultaneously determine specific dynamic action, metabolic substrate use and whole-body protein synthesis in juvenile slipper lobster Thenus australiensis. Juvenile lobsters were fasted for 48 h to investigate routine metabolism before receiving a single meal of formulated feed containing 1% 15N-labeled Spirulina. Postprandial oxygen consumption rate, dissolved inorganic carbon, and total nitrogen excretion returned to the pre-feeding level within 24 h. The rate of whole-body protein synthesis was 0.76 ± 0.15 mg CP g−1 day−1, with a significant reduction from 24 to 48 h post-feeding. The postprandial increase in whole-body protein synthesis accounted for 13–19% of total oxygen uptake. Protein was the primary energy substrate for 48 h fasted (45% oxygen consumption) and post-feeding lobster (44%), suggesting that dietary protein was not efficiently used for growth. The secondary energy substrate differed between carbohydrates in 48 h fasted and lipids in post-feeding lobsters. The present study recommends integrating protein synthesis into protein requirement experiments of marine ectotherms to acquire a more comprehensive picture of protein and energy metabolism and nutritional physiology crucial for formulating cost-effective aquafeeds.
