Temperature-dependent rates of larval development in Limnoperna fortunei (bivalvia: mytilidae)

Mostrar todas las versiones(3)

Laboratory-reared larvae of Limnoperna fortunei (Dunker) were monitored until the morula stage at 26°C, and from there on until settlement at 20, 25 and 28°C. The first polar lobe is produced c. 40 min after spawning, and the first division occurs 14 min later. Slightly over an hour after spawning,...
