Abstract

Induced spawning and culture of Atlantic sturgeon.

Abstract

One male and 2 female Acipenser oxyrhynchus, caught between 28 Feb. and 1 Mar., were injected intramuscularly, about 2 wk after capture, with a preparation of pituitary glands taken from atlantic sturgeons caught 1 yr previously. One of the females and the male , which were placed in the same tank, were found to have released gametes when observed 28 h after injection; the other female had not spawned at this time, and attempts at manual stripping were largely unsuccessful.
