Abstract
The state of gonads is examined for juvenile chum salmon exposed for two weeks at low water temperature, for different stages of their embryonic-larval development. The transfer of the embryos and larvae from the water with temperature of 10.0–12.0 о C to the water with temperature of 1.3–1.8 о C slowed both somatic growth of the fish and development of their germ cells in all cases. The deficit in body weight and ovarian weight of experimental fish was not compensated later. However, the gonad weight was decreased in the somatic component and did not affect the fund of germ cells, in the medium term. The state of ovaries did not differ between the control and experimental groups of fish 50 days after the end of exposure, regardless of the initial condition of gonads in the experiment.
Supporting agencies: The author is grateful to managers of the Sakhalin branch of the Main Fisheries Administration (Glavrybvod) for their assistance in transportation the chum salmon embryos from Sakhalin to the Laboratory of Ichthyology in St. Petersburg State University and to Yu.N. Gorodilov, K.E. Fedorov, A.A. Ivoilov, N.O. Tikhomirova, and N.V. Pimenova (St. Petersburg State University) for their help in laboratory maintenance of the juveniles.
