Resumo: | Pecten maximus larvae exhibit amylase as a main digestive enzyme indicating the possibility of starch hydrolysis. The food value of Rhodomonas salina and Porphyridium cruentum, both rich in starch, on the development of Pecten maximus larvae was investigated. The larval development was studied by means of an image analysis technique and epifluorescence microscopy was used for detecting ingestion and digestion of each phytoplankton species. The biochemical contents of algae and larvae were also assessed. The best growth of Pecten maximus larvae was observed when fed with the mixture PTS (plurispecific control). No growth was observed for larvae fed with Porphyridium cruentum of which most of the population died on day 16 (90%). This algal species was greatly ingested but poorly digested. The larvae fed with Porphyridium cruentum exhibited lower organic content on day 16 than on day 2. On day 23, higher organic content was found in larvae fed with Rhodomonas salina but compared to those fed with Isochrysis aff galbana (monospecific control), their relative composition was similar.
