Food availability is highly variable in the ocean. Many species of marine invertebrates have a larval form that depends upon exogenous nutrients for growth, yet there are few biochemical and physiological indices for determining changes in the nutritional status of larvae. In this study, the effects of food availability on biochemical compositions and metabolic processes of larvae of the sea urchin,...
AbstractEarly development of the Antarctic sea urchin Sterechinus neumayeri was examined under two differ-ent culture regimes: one to simulate development near-bottom (demersal development) and the other to simulate the development of embryos in the water column (pelagic development). When embryos of both treatments reached the hatching blastula stage at 5d post-fertilization (1.5C), the blastulae...
