| Abstract: | The by-product of mussel and vegetable contain a lot of sterots and phosphalides, which are necessary nutrient on exuviation and growth of Prawn. This paper studies that by-products replacing cholesterol crystals in Prawn feed, adding to 1% separately. The result is showed that can promote exuviation and growth of Prawn, feed coefficient is 1.9, survival rate is 44. 58% from fry to goods.Thus it can seen that by - products of mussel and vegetable oil can beed widely used to Prawn feed, because that are cheap and efficient. |
