Effect of broodstock diets on biochemical composition and larval growth of Manila clam, Ruditapes philippinarum (Adams and Reeve, 1850)


Author(s): Julio López-Alvarado

Abstract: The effect of broodstock diets on the subsequent larval growth of Manila clam, Ruditapes philippinarum (Adams and Reeve), was assessed. For the broodstock, two dried diets (a diet of dried Tetraselmis suecica (Kylin) Butch, and a mixed diet of 70 % dried T. suecica and 30 % dried Cyclotella cryptica Reimann et al.), and three live diets (Skeletonema costatum (Grev.) Cleve, Dunaliella tertiolecta (Butcher) and T. suecica) were tested. An unfed group was used as a control. The larvae produced were reared for 7 days on the same diet (Chaetoceros calcitrans). All broodstock diets produced eggs with a high growth potential. Larval growth was worse for the starved broodstock group. The fatty acid composition of the eggs was affected by the broodstock diet. Fatty acids in the larvae after 7 days of culture was very similar for all groups, indicating that the early effect of broodstock diets was later replaced by the effect of larval feed.
