Publication Abstract

A review of egg production in the sole, Solea solea (L.).

S.M. Baynes, B.R. Howell and T.W. Beard

The common sole, Solea solea, readily spawns naturally in captivity. This paper reviews the conditions and procedures used to obtain natural spawning from captive broodstocks and describes the characteristics of egg production. Spawning has been obtained under a wide range of conditions. The time of year has varied, even at the same location, but analysis of published data shows the temperature at which it commenced was related directly to the minimum temperature of the previous winter. Annual relative fecundity has varied from 11 to 141 eggs/g of female with a tendency, although not statistically significant, for the higher values to have occurred following winter temperatures of less than about 12°C. Variations in egg size and fertilization rate have not correlated with larval viability which has been consistently high.
