Castro, M., & Erzini, K. (1988). Comparison of two length-frequency based packages for estimating growth and mortality parameters using simulated samples with varying recruitment patterns (Vol. 86).
Zusammenfassung: Length-frequency distributions were simulated for species with recruitment patterns characteristic of many tropical fish: 1) one recruitment peak per year, fast growth and very high mortality, 2) one recruitment peak per year, slow growth and moderate to high mortality 3) two recruitment peaks per year, slow growth and moderate to high mortality, and 4) random recruitment, slow growth and moderate to high mortality. Two microcomputer program packages – one incorporating the ELEFAN I & II programs and the other implementing a form of Modal Progression Analysis – were used to estimate growth and mortality parameters, and these were compared with the initial parameters used to generate the simulated samples. The results, while generally encouraging, suggest that multiple recruitments per year make it difficult to estimate growth and mortality parameters using these two packages.
