Summary: The visual appearance of fish fillet is important for consumers' purchase decisions. This study used weighted, single-step GWAS to explore the genetic basis of fillet color variation in rainbow trout. Several genetic markers related to carotenoid metabolism, myoglobin homeostasis, protection against lipid oxidation, and muscle structural integrity were identified. These findings have significant implications for improving fillet color in rainbow trout.

Summary: This study evaluated the effects of including black soldier fly prepupae in rainbow trout fingerling diets. The results showed that replacing 50% of fish meal with black soldier fly meal had no adverse effects on growth performance, liver characteristics, feed utilization, or fillet quality. Therefore, black soldier fly meal can safely be used in rainbow trout fingerling diets.

Summary: The study evaluated the effects of replacing fishmeal with partially defatted Hermetia illucens meal on the growth and fillet quality of rainbow trout in a low-tech aquaponic system. There were minimal effects on growth and fillet quality, but certain impacts on gut histology and fillet color and nutritional characteristics were observed at higher replacement rates, warranting further investigation.

Summary: This study compared the fillet nutritional quality of diploid and triploid rainbow trout with the same genetic background, farming condition and body weight. The results showed that diploid trout had higher protein content and amino acid scores, while triploid trout had higher lipid content and fatty acid scores. Both types of trout were suitable for human consumption and had beneficial effects on health. However, triploid trout had higher mineral content and differed in nutritional composition compared to diploid trout. The difference in lipid metabolism may be the reason for these variations.

Summary: The study examined the changes in technological and organoleptic qualities of female rainbow trout flesh after spawning and found that fillet quality gradually recovered over a period of approximately 24 weeks post-spawning. By around 1400 degree C.days after spawning, the quality parameters of the flesh were mostly restored to pre-spawning levels.

Summary: This study investigated the effects of diets incorporating seaweed on rainbow trout, including growth performance, fillet composition, digestive capacity, serum biochemical parameters, and expression of somatotropic axis genes. The results showed that the inclusion of seaweed in the diets did not significantly affect the growth performance and fillet composition of rainbow trout, but it did reduce protein efficiency to some extent. Additionally, the seaweed diets improved the color of fish fillets and had an impact on certain biochemical parameters and gene expression. Overall, diets containing HF showed better results.

Summary: The experiment showed that feeding crayfish with a diet containing 20 g/kg of encapsulated Na-propionate resulted in the best growth performance and highest survival rate. This diet also led to increased enzyme activities in the crayfish gut. Optimum dietary levels of encapsulated Na-acetate, Na-butyrate, Na-lactate and Na-propionate were suggested to be 30.7, 31.8, 31.4 and 33.5 g/kg, respectively, for crayfish reared in culture conditions based on regression analysis.

Summary: The compensatory growth response (CGR) was observed in both sobaity and yellowfin seabream juveniles following a period of feed restriction, with the sobaity exhibiting a full CGR during the refeeding period. Different physiological parameters, including body weight, feed conversion ratio, and antioxidant enzyme activities, showed varied responses to the feed restriction among the two species, indicating that increasing the severity of feed restriction may lead to oxidative stress and compromise the health condition of the fish.

Summary: This study investigated the effects of different levels of DHA enrichment on the growth, survival, fatty acid profile, digestive enzymes, antioxidant parameters, and histology of yellowtail clownfish larvae. The results showed that a DHA concentration of 6% in rotifer enrichment was sufficient to fulfill the DHA requirements and maximize the growth rate of the larvae. High levels of DHA (36%) decreased larval survival, while the DHA12 group had the lowest growth due to lower digestive enzymes and antioxidant activities.

Summary: This study evaluated the effects of humic acid (HA) on nutrient removal efficiency of aquatic duckweed plants and the growth performance and hematological properties of Nile tilapia fish. The results showed that increasing the concentration of HA improved the removal efficiency of ammonia nitrogen and phosphorous by the duckweed plants, as well as the growth performance of the fish. Different concentrations of HA had no adverse effect on the hematological properties of Nile tilapia. Therefore, adding HA to water can effectively improve water quality and fish growth performance in a water recirculating system.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
