Abstract

A good understanding of stock recruit relationships is essential for accurate stock assessment and good fisheries management. But the concept is complicated and can be difficult to understand. This publication uses a recent Florida spotted seatrout stock assessment as an example to show how the stock-recruit relationship allows managers to determine whether or not a given fish population is overfished.
