摘要:Three diets based on three microalgae species (Tetraselmi ssuecica, Isochrysis galbana,andChaetoceros calcitrans) and three feeding rations (1%, 2%, and 3%) were used to understand the ecophysiology of the Mediterranean musselMytilus galloprovincialisduring Broodstock conditioning. Generally, mussels increase their consumption regarding food availability for all diets, and it is evident that the highest consumption was recorded with a feed ratio of 3%. During the study,I. galbanaandC. calcitransstrains show the high consumption (1.58 µg. g-1. h–1±0.00) and (1.58µg. g-1. h–1±0.00) compared withT. suecica(1.542 µg. g-1. h–1±0.023) recorded at 3% food ration of monospecific diets. Same results were recorded for ingestion but with great learning forI. galbanain triscpecific diet (0.70 µg. g-1. h–1±0.052) compared toC. calcitrans(0.36 µg. g-1. h–1±0.037) andT. suecica(0.25 µg. g-1. h–1±0.126), respectively.The analysis of ANOVA has shown that both diet and food availability affect significantly the ingestion (F = 30.9, df = 2,pp
