Aspects of the growth and natural mortality of exploited coral reef fishes uri icon

abstract

  • A newly developed computer-based method for the analysis of length-frequency data (ELEFAN I & II) is applied to data on reef fishes. It is shown that the growth of reef fishes often oscillates seasonally, and that adjusting for this effect considerably increases the accuracy of growth parameter estimates. This is also confirmed by a re-analysis of tagging data from the Caribbean. Potential causes of natural mortality in reef fishes are discussed in the light of a recently established empirical relationship between natural mortality, growth parameters and mean environmental temperature in fishes
