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 ...
Growth and mortality of spangled emperor Lethrinus nebulosus in Fiji
Type: Journal Article
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 ...
Some personal experiences and comments on the management of Italian marine fisheries
Type: Journal Article
The recent transition, in Italy, to an improved sampling scheme for fisheries catch and effort data, is described, with emphasis on the interactions between civil servants and fisheries scientists and on specific features ...
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 ...
On Malthusian overfishing
Type: Journal Article
A brief examination is made of Malthus' works during the 1800s regarding population growth, considering applications to fisheries resources and their management.
Growth and mortality of snapper Etelis carbunculus in Vanuatu
Type: Journal Article
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. ...
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 ...

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 ...
A preliminary account of the population dynamics of Stolephorus devisi (Engraulidae) at Munda Baitground, Solomon Islands
Type: Journal Article
Estimates of growth parameters for Stolephorus devisi (Engraulidae) at Munda Baitground, Solomon Islands were obtained using the Compleat ELEFAN software. Also, estimates of natural and fishing mortality are presented, ...
Kinetic energy and selection in trammel nets
Type: Journal Article
Equations are described that may be used for the calculation of the kinetic energy that a fish carries out during their capture in trammel nets in order to determine the selectivity of the gear. (From an unpublished doctoral ...
