In recent yearsglobal warming and of green marine algaegreen tide, causes significant harm to the coastal environment. has been used as an edible and medicinal plant since ancient times. It is currently used as a food resource, ingredient, and additive for marine fish, shrimp, and shellfish food. However, there are few reports on its use in aquaculture. The aim of this study is to explore the feasibility using juvenile feed. amino acids and fatty acids contained in E. prolifera and common sea cucumber diets (with an average body weight of (5.26±0.14) g were conducted. The results of the nutrition test revealed that is a good source of protein. Of the amino acidsAsp, Glu, Ala, and Leu contents were highest. The overall fat content was low, but the polyunsaturated fatty acid content was above normal. ) contents were all lower than the The results of the feeding trials revealed that during the experiment, each sea cucumber group fed well. There was no significant difference in survival rate among the groups (>0.05). At the end of the trial, the body weight of fed on each diet had increased significantly (>. The feed efficiency relathunbergiiS. muticum<0.05). There was no significant different between the general feeding effect of is a high-protein, low-fat algae food with lower heavy metal content, so it can be used as an alternative or partial substitute for the most commonly used algal food() for juvenile sea cucumbers. This would not only alleviate the shortage ofutilization rate as part of a new comprehensive management strategy.
