“…Additionally, previous findings show that dietary lipid levels are crucial for growth in low-salinity environments (Jannathulla et al, 2019; Chuphal et al, 2021). The current study showed that diets made through extrusion have higher lipid and energy content.…”

In an 8-week trial, the effects of feed processing types (extruded vs. steamed pellets) and protein source (soya/pea vs. fish meal) onLitopenaeus vannameiwere studied under 30 ppt (first 30 days) and 5 ppt (last 15 days) salinity conditions. Diets included D1-SE soya/pea extruded, D2-SS soya/pea steamed, D3-FE fishmeal extruded, and D4 (FS) fishmeal steamed pellets. No significant weight differences were observed. Survival rates (80-97% at 30 ppt) decreased at reduced salinity and were significantly higher for shrimp fed steamed pellets (D2:80.00%, D4:76.67%) compared to extruded (D1: 50.00%, p<0.05). Shrimp fed D2-SS and D4-FS diets had increased lipid content (6.79%, 6.36%, p<0.05). Significantly lower lysine and isoleucine were noted in D2-SS. Behaviourally, at 30 ppt, D3-FE attracted significantly more shrimp (84.72%) than D1-SE (74.49%) and D2-SS (75.70%, p<0.05). Click analysis showed D1-SE and D2-SS with the shortest durations (17.97, 17.24ms, respectively), and D3-FE and D4-FS the longest (20.10, 23.89ms, respectively, p<0.05). Click frequency was also significantly higher in fishmeal–based diets, whereas the number of clicks was higher in shrimp fed extruded feed. Overall, extruded pellets and fishmeal diets were more favourable. These findings emphasize the importance of tailored feed strategies that consider nutritional content, feed physical properties and environmental factors for optimal shrimp feeding.

“…Many studies have shown that the whole-body lipid content increases with increasing dietary lipid levels and excess lipids in the diet may lead to excess fat deposits in the tissues [ 3 , 22 , 33 ]. In this study, the crude lipid content of crayfish did not show significant differences among all the groups.…”

As a new species in aquaculture, the lipid nutrition requirement for the juvenile redclaw crayfish Cherax quadricarinatus on a dietary basis on a practical formula needs to be evaluated accurately. In this study, the optimum dietary lipid level was explained by analyzing the growth performance, antioxidant state, lipid metabolism, and gut microbiota of C. quadricarinatus after an eight-week cultivation trial. Six diets with different soybean oil levels (named L0, L2, L4, L6, L8, and L10) were fed to C. quadricarinatus ( 11.39 ± 0.28 g ). The results indicated that the specific growth rate and weight gain of crayfish fed the L4 and L6 diets were significantly higher than those of the other groups ( P < 0.05 ). By the analysis of a second-order polynomial regression model according to growth performance (weight gain rate), the optimum lipid level in a practical diet for juvenile C. quadricarinatus was 9.67%. The survival, condition factor, and hepatosomatic index of crayfish were not significantly affected by dietary oil levels ( P > 0.05 ). As the level of dietary lipids increased, the total antioxidant capacity and glutathione peroxidase activity in serum showed a tendency to rise and then fall and the enzyme activity was highest in crayfish fed the L6 diet. Gut lipase and pepsin activities showed the highest value in crayfish fed the L6 diet. There was no significant difference in acetyl-CoA carboxylase and carnitine palmitoyltransferase-1 contents in crayfish among all the groups ( P > 0.05 ). The relative abundance of Proteobacteria in the phylum and Citrobacter in the genus showed a significant decrease in crayfish of the L10 diet, while the relative abundance of Firmicutes in the phylum markedly increased compared to that of the other groups ( P < 0.05 ). In summary, the results indicated that the 10.39% (L6 diet) dietary lipid level could induce better growth performance, antioxidant ability, and digestive enzyme activity. Most of the fatty acid composition of muscle is not closely related to the fatty acid composition of the diet. Moreover, the composition and diversity of the gut microbiota of C. quadricarinatus were changed by high dietary lipid levels.

“…Therefore, the most crucial consideration is an adequate nutritional information, especially the knowledge of the dietary nutrient requirements of species in relation to age and environmental conditions [ 3 ]. Dietary lipid is one of the crucial nutrients after protein to spare protein for energy supply, and thus contributes an important role in optimizing the dietary protein for the growth of living organisms [ 4 ]. Dietary lipid also plays an important role in providing essential fatty acids, phospholipid, and fat-soluble vitamins to fish [ 5 , 6 ].…”

“…Likewise, excess dietary lipid levels beyond the optimum level can cause abdominal fat deposition and fatty liver syndrome due to increased leptin levels [ 10 ], which affects the general wellbeing of the fish and the characteristic muscle quality [ 11 ]. So, lipid must be included in the fish diet at an optimum level to maximize protein utilization for better growth [ 4 ].…”

A 60-day feeding trial was carried out to determine the effect of dietary lipid levels on growth and physiometabolic responses to optimize the dietary lipid requirement for maximizing the growth of Genetically Improved FarmedTilapia (GIFT) juveniles reared in inland ground saline water (IGSW) of medium salinity (15 ppt). Formulation and preparation of seven heterocaloric (389.56-449.02 Kcal digestible energy/100 g), heterolipidic (40-160 g/kg), and isonitrogenous (410 g/kg crude protein) purified diets were done for conducting the feeding trial. Random distribution of 315 acclimatized fish (mean weight 1.90 ± 0.01 g) was made in seven experimental groups such as CL4 (40 g/kg lipid), CL6 (60 g/kg lipid), CL8 (80 g/kg lipid), CL10 (100 g/kg lipid), CL12 (120 g/kg lipid), CP14 (140 g/kg lipid), and CL16 (160 g/kg lipid) with 15 fish per triplicate tank (fish density, 0.21 kg/m3). Respective diets were used for feeding the fish at satiation level three times daily. Results indicated that weight gain percentage (WG%), specific growth rate (SGR), protein efficiency ratio, and protease activity significantly increased up to 100 g lipid/kg fed group, and then the values significantly decreased. Muscle ribonucleic acid (RNA) content and lipase activity were highest in 120 g/kg lipid-fed group. RNA/DNA (deoxyribonucleic acid) and serum high-density lipoproteins levels of 100 g/kg lipid-fed group were significantly higher than 140, and 160 g/kg lipid-fed groups. The lowest feed conversion ratio was found in the 100 g/kg lipid-fed group. The amylase activity was significantly higher in 40 and 60 g lipid/kg fed groups. The whole-body lipid level was increased with increasing the dietary lipid levels, whereas, there was no significant difference in whole-body moisture, crude protein, and crude ash contents of all groups. Highest serum glucose, total protein and albumin, and albumin to globulin ratio and lowest low-density lipoproteins level were found in 140 and 160 g/kg lipid-fed groups. Serum osmolality and osmoregulatory capacity did not vary significantly, whereas carnitine palmitoyltransferase-I and glucose-6-phosphate dehydrogenase showed an increased and decreased trend, respectively, with the increasing dietary lipid levels. According to second-order polynomial regression analysis based on WG% and SGR, the optimum dietary lipid for GIFT juveniles in IGSW of 15 ppt salinity was found to be 99.1 and 100.1 g/kg, respectively.
