A brown seaweed Sargassum ilicifolium as binder in water stability and absorption of Shrimp feed

The importance of producing aquaculture feeds which is water stable, particularly for crustacean use, feeding efficiency and reducing FCR and obtaining high production, has been mentioned. Since, many different substances chemicals and neutral have been used for increasing the water stability of aquaculture diets. Till now chemical ones such as Poly Sorbate, Carbapol, Poly Methyl Carbamide or Basfin (a kind of polymer of urea formaldohyde), Bentonites and … were used which is not towards on security policy of feeding. In this project, the aim is using Sargassum ilicifolium as a marine brown seaweed which is abundant in coast of Iranian south beaches as binder in zero, 2 and 5% of shrimp feed pellete comparing to chemical binder poly Sorbate used in control feed showed water stability and water absorbtion of pellet with 5% seaweed, higher than poly Sorbate treatment, statistically and made better texture, color, taste and scent feed for shrimp culture.
