Histological ovarian analysis indicates summer spawning occurs in Myoxocephalus quadricornis (Fourhorn Sculpin) from Alaska. Previous studies have shown this species spawns during winter in the Baltic Sea; the data presented herein suggests that geographical variation may occur in the timing of spawning of this species.
We discovered a hermaphrodite Liopsetta glacialis while examining tissues from a sample of 30 representatives of this species for a histopathological survey of fishes from the Beaufort Sea, Alaska. L. glacialis occurs in the Arctic Ocean from Queen Maude Gulf in arctic Canada, along the North American and Siberian coasts to the White Sea and Barents Sea (Morrow, 1980). The specimen was collected from Beaufort Lagoon on July 29, 1984, weighed 15, measured 100 mm (total length) and was between 3 and 4 years old.
