The parameter L8 and K of the von Bertalanffy growth equation were estimated from length-frequency data of teh spangled emperor Lethrinus nebulosus (Fam. Lethrinidae) caught in the Central and Western Divisions, Fiji. These parameters are compared with values from Papua New Guinea and New...

Catch and effort data from the river fisheries of the Peruvian part of Amazonia are presented, and used to fit a Schaefer-type surplus production model. This suggests that present effort is in excess of what is required to generate Maximum Sustainable Yield, and that and increase in effort would...

The growth performance of a number of wild populations of the African catfish C. gariepinus (Clariidae) was assessed by means of the growth index ╪. The values of ╪ ranged from 2.97 to 3.67 with some of the highest values coming from the coldest lakes, suggesting that this catfish...

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 stock assessment methodology are discussed, and the need for the...

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 management of exploited multispecies fish stocks.

The spawning season of the Caribbean spiny lobster Panulirus argus (Latreille) was identified based on adult specimens collected monthly off northeastern Brazil, from August 1982 to July 1988. The maturity indices used were relative abundance of females with full spermatheca, eggs or rests of...

The International Center for Living Aquatic Resources Management (ICLARM) in collaboration with the Food and Agriculture Organization of the United Nations (FAO) and with the support of the Commission of the European Communities is developing a database (called FISHBASE) to summarize global...

Based on length-frequency distributions and mean annual water temperature, growth and mortality parameter estimates, as well as spawning pattern of Pellonula leonensis (Clupeidae) occurring in the Cross River (Nigeria) have been obtained. The estimated von Bertalanffy growth parameters are TL8 =...

Length-frequency data, collected using beach seines, on the common silverbiddy Gerres oyena (Gerreidae) in Tarawa Lagoon, Kirbati (northern Gilberts Group), from September 1976 to October 1977 were analyzed using the Compleat ELEFAN software. This analysis and basic knowledge of the...

This paper presents estimates of the parameters L8 and K of the von Bertalanffy equation, as obtained from length-frequency data on the lutjanid Etelis carbunculus from Vanuatu, analyzed using teh Compleat ELEFAN software. These estimates are compared with values of L8 and K obtained for other...
