Abstract

1. Lipoprotein lipase and salt-resistant lipase activities increased in the ovaries but decreased in the adipose tissue of female trout in the months leading up to spawning. 2. The activity of the plasma cholesterol esterifying enzyme increased significantly immediately prior to spawning. 3. Plasma lipoprotein concentrations decreased during the approach to spawning. 4. These studies suggest that the developing ovaries in the trout receive their nutrients by lipolysis of plasma lipoproteins as well as by vitellogenin uptake; differentiation of the roles of the lipid stores in different tissues is proposed.
