Abstract: By bioassay, evaluation was made of the activity and relative potency of pituitaries collected throughout the year from various species of fish. Positive response was indicated by ovulation of eggs or by increases in seminal plasma. |

Abstract: Actvity of pituitaries collected in various months did not vary as much as the individual variations in physical condition of the test fish. The data indicate that all the pituitaries are active in the months in which collections were made. Activity in relation to size, sex, and degree of gonadal development of the donor fish does not appear as important as implied by some previous reports in the literature. |
