- Abstract
Simple Summary: This study presents an analysis of the gastrointestinal tract (GIT) of Malabar red snapper, comparing it with Asian seabass. It highlights slight differences in moisture content, crude protein, and ash between the two species, with Malabar red snapper showing higher essential fatty acid levels. Additionally, Malabar red snapper's GIT features protective mechanisms in the esophagus and distinct glandular densities in the stomach. The intestine also shows variations in goblet cell distribution and acid mucin secretion along its length. These findings offer valuable insights for the aquaculture sector, especially concerning Malabar red snapper. This study offers a comprehensive morpho-histological analysis of the gastrointestinal tract (GIT) of the Malabar red snapper. A comparison of its GIT morphology with that of the Asian seabass reveals similarities and differences between the two species. Additionally, the moisture content, crude protein, and ash in the fillets of Malabar red snapper and Asian seabass were slightly different, with Malabar red snapper exhibiting higher levels of essential fatty acids. Furthermore, higher levels of the polyunsaturated fatty acid (PUFA)/saturated fatty acid (SFA) ratio and docosahexaenoic acid (DHA)/eicosapentaenoic acid (EPA) ratio, and a lower omega-6/omega-3 ratio, were observed in Malabar red snapper compared to Asian seabass. The Malabar red snapper's esophagus featured protective mechanisms such as simple columnar epithelial cells, mucous-secreting glands, and goblet cells that were predominantly stained for acid and neutral mucosubstances. Furthermore, its stomach, with mucus cells that were weakly stained for acid mucosubstances, exhibited distinct regions with varying glandular densities, with the pyloric region featuring few glands. The pyloric caeca of the fish were composed of five finger-like structures and few goblet cells. Several goblet cells gradually increased from the anterior to the posterior region of the intestine. These findings provide useful insights for the aquaculture sector, focusing on Malabar red snapper.
