Population dynamics of Metapenaeus ensis (Penaeidae) in the Gulf of Papua, Papua New Guinea
(1990)Type: Journal ArticleGrowth, total mortality and seasonality of recruitment of male Metapenaeus ensis (Penaeidae) were determined based on length-frequency data (n = 9007) collected in 1988 in the Gulf of Papua, Papua New Guinea. -
Growth, mortality and recruitment of exploited small pelagic fishes in the Gulf of California, Mexico
(1990)Type: Journal ArticlePreliminary, length-based von Bertalanffy growth parameter estimates for Sardinops caeruleus, Opisthonema libertate, Scomber japonicus, Etrumeus teres, and Engraulis mordax, caught in the pelagic fishery based in Guaymas, ... -
On Malthusian overfishing
(1990)Type: Journal ArticleA brief examination is made of Malthus' works during the 1800s regarding population growth, considering applications to fisheries resources and their management. -
Reproductive season of the Caribbean spiny lobster Panulirus argus in the coastal waters of northern Brazil
(1990)Type: Journal ArticleThe 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 ... -
A search for new methods for fish stock assessment and management: the FSA-CRSP overview and Philippine activities
(1990)Type: Journal ArticleA 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 ... -
Some personal experiences and comments on the management of Italian marine fisheries
(1990)Type: Journal ArticleThe 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 ... -
The applicability of ELEFAN for use in analyzing three species of deepwater snappers in Tonga (Etelis coruscans, Pristipomoides flavipinnis and P. filamentosus, Fam. Lutjanidae)
(1990)Type: Journal ArticleAn 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 use of surplus-yield models in the economic analysis of a fishery
(1990)Type: Journal ArticleDiscounted cash flow techniques, as typically employed in the evaluation of fishery projects, employ constant cost and revenue streams over the duration of the project. The implicit assumption is that additional effort in ... -
Can we use traditional length-based fish stock assessment when growth is seasonal?
(1990)Type: Journal ArticleBased 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 ... -
Kinetic energy and selection in trammel nets
(1990)Type: Journal ArticleEquations 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 ... -
Estimating natural mortality of Kuwait's Penaeus semisulcatus using a new tag-recapture data analysis method
(1990)Type: Journal ArticleA novel method was used to estimate natural mortality (M) of Kuwaiti Penaeus semisulcatus using tagging data. The new M estimator is based on two tagging experiments with similar products of initial survival after tagging ... -

(1990)Type: Journal ArticleEstimates 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, ... -
Catch assessment of Sardinella maderensis in the Ocean Division, Cameroon
(1990)Type: Journal ArticleCatch 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 ... -
