The applicability of ELEFAN for use in analyzing three species of deepwater snappers in Tonga (Etelis coruscans, Pristipomoides flavipinnis and P. filamentosus, Fam. Lutjanidae)
Type: Journal Article
An attempt to fit the von Bertalanffy growth equation to three species of deep sea snappers using the ELEFAN method was unsuccessful, mainly because the fish are slow-growing, long lived species. Problems were also encountered ...
The accuracy of some length-based methods for fish population studies
Type: Report
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. ...
A search for new methods for fish stock assessment and management: the FSA-CRSP overview and Philippine activities
Type: Journal Article
A brief account of the USAID funded fish stock assessment collaborative Research Support Program is given, with emphasis on its Philippine module, devoted to empirical analyses, modelling and field studies aimed at improved ...
Catch assessment of Sardinella maderensis in the Ocean Division, Cameroon
Type: Journal Article
Catch assessment estimates for the motorized and non-motorized canoes at Boa-Manga (Cameroon) were found to be 5.13 and 2.70 t/year, respectively, leading to an estimated lower limit for the production of the Ocean division ...
Can we use traditional length-based fish stock assessment when growth is seasonal?
Type: Journal Article
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 ...
