The invention relates to an environment-friendly holothurian compound feed which is holothurian basal feed comprising algae powder, fish meal, bean pulp, sea mud, corn flour, shell powder, multi-vitamin and mineral substance, and is characterized in that the holothurian basal feed is added with 0.1% of phytase and cellulose as enzymic preparations; the holothurian basal feed is added with 0.1% of photosynthetic bacteria, ammonifying bacteria, nitrifying bacteria, denitrifying bacteria and nitrite bacteria as microbial preparations; and the holothurian basal feed is added with 2% of sodium alginate and 3% of cassava alpha- starch as auxiliary agents. Compared with the existing commodity holothurian feed, the stability of the environment-friendly holothurian compound feed in water is remarkably improved, the loss rate of nutrient components is remarkably reduced, influence for the water quality of the aquaculture is low, and the turbidity, the ammonia nitrogen content and the chemical oxygen demand (COD) value of the water are obviously reduced after baiting. Meanwhile, the preparation method and technique of the feed are simple, the cost is lower, large-scale production is easily carried out, and the environment-friendly holothurian compound feed has good popularization and application prospects in the holothurian production.
