Can we use traditional length-based fish stock assessment when growth is seasonal?

Fishbyte, 1990, vol. 8, issue 3, 29-32

Abstract: Based on simulated catch data, this contribution shows that standard length-converted catch curves cannot be used for accurately estimating total mortality when growth oscillates seasonally. Some implications for length-based stock assessment methodology are discussed, and the need for the development/implementation of methods not requiring length-to-age conversions is emphasized.
