Summary: This study aimed to evaluate the effects of diets containing different levels of hydrolyzed porcine mucosa on the growth performance, muscle nutrition composition, texture property, and gene expression related to muscle growth of hybrid groupers. The results showed that hybrid groupers fed a diet with 6% hydrolyzed porcine mucosa and 27% fish meal had comparable growth performance to the control group. Additionally, a diet containing 3% hydrolyzed porcine mucosa upregulated gene expressions related to muscle growth and improved muscle quality. An appropriate amount of hydrolyzed porcine mucosa could be effectively used in grouper feed.

Summary: An 8-week feeding experiment was conducted to investigate the effect of dietary histamine on the growth performance, digestive physiology function and muscle quality of hybrid grouper. The results showed that high levels of histamine significantly decreased the activities of digestive enzymes, damaged the gastric and intestinal mucosa, disrupted the intestinal tight junction structure, and affected the muscle quality of the grouper.

Summary: The optimum threonine requirement for maximum growth of juvenile hybrid grouper was estimated to be 11.48 g/kg of dry matter. The mRNA expression of hepatic growth hormone receptor 1 was higher in fish fed diets with 11.5 and 13.7 g/kg dietary threonine. Fish fed diets with 5.4 g/kg threonine had the lowest whole-body protein contents and expression of hepatic target of rapamycin and ribosomal protein S6 kinase 1.

Summary: This study investigated the embryonic and larval development, morphological changes, sensory organ development, and behavioral patterns of the backcrossed hybrid grouper TGGGxGG. The study found that fertilization and hatching rates were 70.65% and 39.51% respectively, with an average egg size of 850 & PLUSMN; 40 & mu;m. The newly hatched larvae grew from 1.336 & PLUSMN; 0.118 mm to 11.95 mm at 50 days after hatching (dAH), initiating first feeding at 48 hours after hatching (hAH). The TGGGxGG larvae exhibited positive phototaxis at 48 hAH and positive rheotaxis at 4 dAH. The study also observed the development of free neuromasts on the head parts of the larvae. The backcrossed hybrid TGGGxGG showed similar developmental characteristics to other pure and hybrid groupers, but had slower growth, suggesting the need for further investigation into growth enhancement.

Summary: Grouper culture in Malaysia is expanding due to high demand, but infectious diseases like vibriosis are causing increased mortality rates and affecting production. This study focused on the metabolic profiling of infected grouper fed with different fatty acid diets to improve growth and health. The results showed that oleic acid as an immunostimulant had a strong impact on immune-related metabolites in infected grouper.

Summary: This study revealed the molecular mechanism of skin color transformation in the hybrid Hulong grouper through transcriptome analysis. The results showed that immune response genes were related to pigmentation variance, and the normal group had stronger immune status and anti-oxidative stress ability. The MAPK signaling pathway was involved in fish skin color regulation. In addition, genes related to melanin synthesis had the highest expression level in individuals with normal color.

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.
