The accuracy of some length-based methods for fish population studies

Abstract

Monte-Carlo simulations of fish populations with different biological characteristics were generated to test the accuracy of some recent methods for the assessment of growth in fishes on the basis of length data. Threemethods were investigated: D. Pauly and N. David's Electronic Length-Frequency Analysis (ELEFAN), J.G. Shepherd's Length Composition Analysis (SLCA) and the method derived by J.V.-Wetherall from the general model of D.G. Powell referred to as the
