The experience of using Arthrospira platensis as a feed additive in the cultivation of juveniles of the Far Eastern sea cucumber (Apostichopus japonicus)

Abstract

The experience of using the culture of Arthrospira (Spirulina) platensis as an additive to feed when growing juveniles of the Far Eastern sea cucumber in aquarium conditions is described. The experimental food ration included live culture of spirulina, macroalgae, protein and stimulant supplements. There were no significant differences in the survival rates of individuals (experiment – 69.5%, control – 65.7%). The greatest increase in the mass of individuals was observed in the experimental container - by an average of 0.047 g. In the control group - an average of 0.009 g.
