Abstract
Abstract Effects of food availability on larval growth and survival of Spirobranchus kraussii were studied by feeding larvae different algal diets. Newly hatched larvae of S. kraussii were fed four different marine microalgae species, singly and in various mixtures. The best growth was observed when fed C. vulgaris, N. oculata as a single species and mixed-algal diet during day 15 after fertilization. Mortality was low for larvae (max. 5%); survival rate more than 95%. These results suggest that S. kraussii larvae have the capacity to feed using alternative sources of energy, and food size and quality can affect their growth and sustainability.
期刊介绍：
The Croatian Journal of Fisheries was established in 1938 and today possesses a long-term tradition of publishing papers that deal with both freshwater and marine fisheries. Areas covered by the Journal include ichthyology, aquaculture, ecology and diseases of fish and other aquatic organisms, problems of open waters and other topics related to the fisheries field. Prior to publication, articles pass through rigorous review by senior scientists from around the world. The Journal features articles that reflect original research, interpretative content and subject matter of interest to the fisheries profession.
