. The relationship between absence of functional swim‐bladder, calculosis and larval mortality of hatchery‐reared sea bream, Sparus aurata L., was observed. There was a temporal variation in the main causes of mortality, i.e. not inflated swim‐bladder appears to be the main cause up to the 47th day, and the presence of calculi around the 55th day. Histological sections, semi‐quantitative analysis and scanner electron microscope photographs were carried out.
