Fecundity of the yellow perch, Perca flavescens Mitchill, in the Bay of Quinte, Lake Ontario

Abstract

The relationships between the logarithm of the number of ova shed by yellow perch in the Bay of Quinte and length, weight, and age of the fish were found to be: Y = 2.982 + 0.007X where X is length in millimeters; Y = 3.769 + 0.004X where X is weight in grams; Y = 3.780 + 0.098X where X is the age in completed years. The logarithm of the number of mature ova spawned = 4.082 + 0.003 multiplied by the ovary weight in grams. Individual fecundity ranged from 3035 for a II + fish, 135 mm, 27.2 g to 61 465 for a VIII + fish, 257 mm, 308.4 g.
