Observations of Length at Maturity in Yellowtail Flounder on the Grand Bank (1995-97)
Length and age at maturity are essential information to determine the spawning stock biomass and stock-recruit relationship. The usual knife-edge estimates of the mature proportions in fish populations obscure the knowledge on the true levels of the spawning potential of the stocks and the temporal...
