Abstract

The rapidly expanding aquaculture sector of the worldwide fisheries industry is mostly due to fish feed. Omega-3 long-chain polyunsaturated fatty acids, which are good for fish health and growth, are mostly found in fish oil. However, the cost of fish oil is increasing while its production is declining. Aquaculture can be maintained with the use of alternate aquafeeds. Due to their quick growth, aquatic protists have a lot of potential as a source of omega-3 oil. Schizochytrium sp. can be used to substitute fish oil in aquafeed due to its high lipid and DHA content, according to numerous research. The purpose of this review is to determine the effects of utilizing Schizochytrium sp. in fish feed on fish growth and health. The nutritional value and optimal dosage of Schizochytrium sp. for various fish sizes are discussed. The optimal concentration of Schizochytrium sp. varies by species and can replace fish oil in the range of 20–80%. Several studies found that replacing fish oil in fish food with Schizochytrium sp. made the fish grow faster, live longer, gain weight, and eat more food. In the future, Schizochytrium sp. and several types of marine protists have the potential to serve as alternative sources that can replace fish oil in fish feed.
