| Abstract |
| The aquaculture industry is one of the main sources of human food supply, which is the fastest food production sector in developing countries, however, one of the main challenges in this industry is the improvement of formulated food rations to optimize the growth and improve the health of fish. The increase in production and processing has led to the production of a significant amount of waste and this waste constitutes approximately 30 to 70% of the total aquatic consumption. One of the materials that can be synthesized from aquatic wastes is chitosan also substances obtained from the sea have an effective stimulating and antioxidant effect when introduced to aquatic animals. Chitosan is known as a versatile biological material due to its non-toxicity, low sensitizing, biocompatibility, and biodegradability. In terms of its chemical structure, it is a polymer of glucosamine, and it is obtained from the deacetylation of chitin. For example, this substance as a food supplement can incredibly increase the growth performance of tilapia fish and crabs due to the enzyme reaction in the digestive system. The research conducted on Vannamei shrimp (Litopenaeus vannamei), (Paralichthys olivaseus) and Roho carp (Labeo rohita) has shown that the use of chitosan improves growth performance. in common carp (Cyprinus carpio) it increased the activity of the non-specific immune system, decreased mortality and increased fish growth under stress conditions. Shrimp feed enriched with curcumin and chitosan nanoparticles (CSNPs) as a drug carrier (Cur-CSNPs) may be useful for strengthening aquatic animals against oxidative stress. Oral administration of chitosan in rock grouper (Epinephelus bruneus) shows a significant increase in the number of red blood cells, white blood cells, hematocrit, and hemoglobin. Also, in carp (Labeo rohita) it improves the specific growth factor, food conversion factor, total protein, albumin, globulin, blood serum lysozyme and hemoglobin and in tiger shrimp (Penaeus monodon) and loach fish (Misgurnus anguillicadatus) influences stimulating the immune system. As a result, the use of chitosan is of great help to the aquaculture industry both in terms of creating added value and in terms of improving the food ration and increasing the safety of aquatic animals. |
