Biochemical composition and larval viability in Mytilus galloprovincialis: preliminary data and methodological aspects

[EN] Four batches of Mytilus galloprovincialis eggs were reared under laboratory conditions. Biochemical composirion, growrth and mortality were analyzed in the eggs and in 0,13 and 20 days old larvae, the oldest ones showing a variable percentage of eyed larvae. 
\nIn the present work, an analytical method for the study of lipid classes by Thin Layer Chromatograph (TIC)-densitometry is developed. The utilization of energetic reserves during larval development in M. galloprovincialis is studied as well as the relationship between those compounds and larval viability. 
\nOur results show a possible relationship between larval growth and mortality in days 13 and 20 of development and the triacylglycerol content of those larvae.
