Summary: This study evaluated the effects of long-term feeding of a fishmeal-free (FMF) diet on the growth parameters and physiological status of red sea bream yearlings. The results showed that the FMF group had significantly lower body weight and feed intake compared to the control group. The concentrations of serum total cholesterol and high-density lipoprotein cholesterol were also significantly lower in the FMF group. Moreover, the total bile acid amount was significantly lower in the FMF group during the lowest water temperature period.

Summary: The objective of this study was to investigate the potential of enhancing the dietary substitution of fishmeal with corn protein concentrate in the diets of red hybrid tilapia. The results showed that high levels of corn protein concentrate significantly reduced fish growth and feed intake, but blending it with soy protein concentrate restored the growth performance of tilapia.

Summary: The study found that poultry byproduct meal can be a suitable replacement for fishmeal in red snapper diets, but high levels of soybean meal negatively affect growth performance, regardless of the addition of taurine or a palatability enhancer. Further investigation is needed to determine the optimal taurine requirement and dietary supplements to improve the performance of low fishmeal feed formulations.

Summary: The study showed that reducing TI activity in SPC from soymilk to <= 21 TIU/mg sample (<= 9.66 TIU/mg diet) allowed replacement of 80% of FM protein without affecting growth performance and health status. Additionally, a significant decrease in phosphorus discharge suggests ecological benefits through improving diet utility by lowering TI activity in SPCs from soymilk.

Summary: This study investigated the effects of adding bile acids to a low fishmeal diet on the growth, nutrient utilization, and serum biochemical parameters of Pacific white shrimp. The results showed that the addition of bile acids can improve the growth performance and nutrient utilization of the shrimp in the low fishmeal diet group.

Summary: The study found that supplementing with taurine significantly affected the weight, growth rate, feed intake, and various blood parameters of white shrimp, while replacing fishmeal with soybean concentrate had a significant impact on growth performance depending on the replacement ratio, with up to 50% replacement showing no negative effects.

Summary: A series of studies found that fish residue meal (FRM) can be used as a complete replacement for fish meal (FM) in the diet of red sea bream without compromising growth performance and health status. This research has important implications for achieving sustainability in the aquaculture industry.

Summary: An 8-week feeding trial was conducted to investigate the effect of selenium-yeast supplementation on replacing fishmeal with soy protein concentrate in diets for golden pompano. The results showed that the inclusion of selenium-yeast improved the growth rate and nitrogen and phosphorus utilization efficiency of golden pompano, while reducing feed intake and nitrogen and phosphorus waste. Therefore, replacing fishmeal with soy protein concentrate and adding 1 g/kg of selenium-yeast in the diets is feasible for golden pompano.

Summary: The study found that the inclusion of brown seaweed can improve the growth performance and feed utilization of Japanese flounder, especially when partially replacing fishmeal with soy protein. The addition of seaweed also led to changes in total lipid content and fatty acid composition in the fish feed.

Summary: Three isoenergetic diets with different fishmeal/soy protein concentrate ratios were assessed for their effects on tissue growth and energy budget of juvenile crabs. The results showed that the diets had similar feed conversion, protein retention, and energy retention. However, these parameters were significantly higher in the postmolt stages compared to the intermolt stages. The energy budgets were marginally affected by diet but significantly affected by molt stage, with lower maintenance energy in the postmolt stages and higher recovery energy in the intermolt stages.

Summary: In this study, an 8-week feeding trial and challenge experiment were conducted to investigate the effects of different concentrations of CB on the growth performance, antioxidant capacity, immunity, and resistance to Vibrio parahaemolyticus in Litopenaeus vannamei. The results showed that the supplementation of CB at appropriate levels significantly enhanced the antioxidant capacity, immunity, and disease resistance of shrimp, while improving their growth performance.
