Última Les méthodes delta en halieutique. Evaluation des sensibilites, approximation des biais et variances à l'aide de developpements limites ArchiMer Laurec, Alain. This report presents an introduction to so called "delta methods", associated to the use of Taylor's expansions, as a tool for sensitivity analyses. It starts with a mathematical and statistical summary about Taylor's expansion and moments of random variâtes. Special attention is paid to multivariate problems. The application of order 1 and 2 expansions to estimate variances and biases is exposed in great details. This report dedicated to fisheries scientists, is finally illustraded by an example associated to yield per recruit calculations, based upon JONE'S length cohort analysis.

Ano: 1987 URL: https://archimer.ifremer.fr/doc/1987/rapport-1565.pdf Exploitation, biologie et dynamique du stock de langouste rouge de Corse, Palinurus elephas Fabricius ArchiMer Marin, Jean. The European red spiny lobster (Palinurus elephas) is the main target species of the small-scale fishery in Corsica. This fishery was described, its trends from 1981 to 1964 were analysed, and the exploitation conditions of the spiny lobster stock (fishing grounds, strategy and gear ; fishing regulations) were explained. Furthermore, the fishing effort and the yields were estimated through an indirect survey, in 1983 and 1984 . The growth was studied through tagging experiments. Growth increment per moult, Von BERTALANFFY's equation parameters, and moulting frequency were estimated for both sexes. Bias risks associated to tag loss at moulting were also analysed. In addition, estimates of K and L∞ variances were provided through "Jack-knife"...
