Embryonic and larval development of Dissostichus eleginoides (Pisces: Nototheniidae)

This is the first description of the embryonic and early larval development of laboratory-reared (4-8°C) Dissostichus eleginoides. Specimens were periodically sampled to describe egg and larval development. Eggs were spherical (3.1-3.5 mm diameter) and had a transparent chorion and slightly rough su...
