Ecophysiology of the Mediterranean mussel Mytilus galloprovincialis L; effect of different microalgae diets and ration on broodstock conditioning

Three diets based on three microalgae species ( Tetraselmi ssuecica , I sochrysis galbana, and Chaetoceros calcitrans ) feeding rations (1%, 2%, 3%) were used to understand the ecophysiology of Mediterranean mussel Mytilus galloprovincialis during Broodstock conditioning. Generally, mussels increase their consumption regarding food availability for all diets, it is evident that highest was recorded with a feed ratio 3%. During study, I. galbana C. strains show high (1.58 µg. g -1 . h –1 ±0.00) (1.58µg. compared T. suecica (1.542 ±0.023) at 3% ration monospecific diets. Same results ingestion but great learning in triscpecific diet (0.70 ±0.052) (0.36 ±0.037) (0.25 ±0.126), respectively.The analysis ANOVA has shown both affect significantly (F = 30.9, df 2, p < 0.001 F 4.4, 6, 0.001)
