Blicca bjoerkna The long period of tranquillity is followed in early spring by a rapid gain in ovary weight which is a result of increasing day length, temperature, and improving food supply. By April, the intensity of ovogenesis in the ovaries increased again. The GSI value increased one and a half times in a short period of time (from 5.67% to 8.67%) [...] Thus, in the one - one and a half months prior to spawning vert intensive qualitative and quatitative processes can be observed in the ovary. This is the most intensive period of the ovarian cycle which is shown by quantifiable reproductive indicators. ['April', 'May', 'June'] Lefler, 2008
