Length-converted catch curves and the seasonal growth of fishes

Author

Listed:
  • Pauly, D.

Abstract

A brief review of studies on the seasonal growth of fish is presented, followed by an equally brief review of length-converted catch curves. A new method for constructing catch curves from representative length-frequency data is presented. This new method explicitly accounts for seasonal growth and thus eliminates the bias in Z caused by such growth. Some practical and theoretical implications of the new method are discussed.
