Patagonian toothfish, Dissostichus eleginoides, spawn over the continental slope from July to September. Eggs have been observed primarily in the upper part of the water column over 2200-4400 m bottom depth. Embryos in stage III and IV of their embryonic development are described. Hatching is likely to occur in October/November. Scales do not start to form before the fish are 64-74 mm long.
