| Abstract | ||||
| The global requirement for fish protein in growing, meeting challenges within the aquaculture industry, and addressing consumer demands becomes imperious. Enhancing fish reproduction and in turn promoting overall growth are among these challenges. To achieve such goals and benefit the aquaculture projection, various researches were conducted to explore a protein replacer of high nutritive value and achieve the desirable purposes. Owing to their lower costs and availability, seaweeds have attracted more attention as a good source of bioactive nutrients. Algae succeeded as a novel substitute of protein-based sources with potential nutritional benefits in aquaculture purposes. Thus, a rise in protein content of seaweed is duly contributory in improved ovary morphology and fish reproduction. Gastropods and other molluscs species are among the principal group of structurally unique natural output in Red Sea, Egypt. From the histological aspect, the outline of this plan was to estimate the potential effect of marine algae in the enhancement of reproductive performance of marine fish. Overall, 45 Strombus Tricornis conchs within 100 ± 20 g evenly classified into three experimental groups (n=15) incorporated with three successive seaweeds classes including racemosa, J. rubens, and D. ciliolate. Female gonads specimens were collected from control sea conches and experimental groups for histological monitoring. In comparison with the standard sea samples, seaweeds enhanced the reproductive histomorphology in Strombus species, promoting follicle maturity, oocytes sizes, and epithelial development. Seaweeds are an emerging tool with potential positive influence utilized to replace the protein in the feed formulation for aquaculture practices. | ||||
