Approche de la dynamique de stocks accessoires ArchiMer
Moguedet, Philippe.
For a few years now, the landings from the Lorient's industrial fleet have been continually increasing (32,000 tons in 1980, 56,000 tons in 1985). This fleet practices a multispecific exploitation of the international fishery of the west and north of Scotland. The rock salmon (Pollachius virens) is the fleets' target species, its catches of other gadidae are considered secondary. Two of the catches, those of the blue ling (Molva dypterygia) and the ling (Molva molva) have been advancing since the beginning of the decade and in 1985 represented 21% of the total amount in quantity and value landed by the industrial fleet. The objective of this study is to asses the status of these ling resources and examine whether their exploitation can, in the short term,...

Cod (Gadus morhua) Migrations in the Gulf of St. Lawrence and Areas South of Newfoundland ArchiMer
Moguedet, Philippe.
During the years 1975, 1976, 1980 and 1982 cod (Gadus morhua) tagging experiments were conducted, inside the Gulf of St. Lawrence and outside in areas south of Newfoundland, by French scientists from IFREMER St. Pierre and Miquelon laboratory, in order to study the population distribution and migration and to complement the experiments carried out by Canadian scientists. The analysis from all recoveries and results from these experiments are presented here. The relevance is that the comparison with the Canadian results would lead to a better understanding of the cod stock exchanges in the area. The migratory patterns were believed to be mainly a response to seasonal environmental condition changes. In winter the cod were noted to migrate from the central...

Diagnostic sur l'état de la ressource de vivaneau rouge (Lutjanus purpureus) exploitée dans la Z.E.E. de la Guyane Française - 1994 ArchiMer
Moguedet, Philippe.
1.Historique de la pêcherie La pêcherie de Lutjanidés conduite dans la Zone Economique Exclusive au large de la Guyane Française concerne trois espèces, le vivaneau rayé (Lutjanus synagris), le vivaneau "ti-yeux" (Rhomboptiles aurorubens) et le vivaneau rouge (Lutjanus purpureus). Cependant seule cette dernière présente un réel intérêt commercial; c'est l'espèce cible d'une flottille artisanale vénézuélienne qui utilise pour l'exploiter un art de pêche dormant, la ligne à main. L'exploitation des vivaneaux au large des côtes de la Guyane Française a toujours fait l'objet d'une activité d'origine étrangère et plus particulièrement vénézuélienne. Avant la création de la Zone Economique Exclusive les produits de cette activité traditionnelle des pêcheurs...

Estimation des coefficients de mortalité et de l'abondance des recrues à partir de l'analyse d'une pseudocohorte dans le cas d'une exploitation par différents métiers ArchiMer
Bertignac, Michel; Moguedet, Philippe.
An adaptation to the cohort analysis is suggested when age catches distribution are known only on a year and when the effort datas ot previouses years, for each ot the vessels fishing the considerated stock, are availables. An example to the estimation of fish mortality coefficients and of the recruitment abundancy for the stocks of sea bass (Dicentrarchus labrax) from Morbras (ICES division VIII A) and ling (Molva molva) from west of Scotland (ICES division VI A), is given.

Evaluation du volume et cartographie des captures accessoires de la pêcherie de crevettes Pénéïdes en Guyane française ArchiMer
Moguedet, Philippe; Nerini, David; Gueguen, F..
Depuis l'extension de la Zone Economique Exclusive française à 200 milles au large des côtes de la Guyane française (Amérique du sud), une flottille d'environ soixante dix chalutiers industriels battant pavillon français, exploite le stock de crevettes pénéïdes (Penaeus subtilis) présent dans ces eaux. Cette pêcherie est gérée par un système de T.A. C. 's fixé annuellement par la Communauté Européenne. Comme dans de nombreuses autres pêcheries de ce type en eaux sub-tropicales ou équatoriales le taux des prises accessoires est élevé. L'objectif de cette étude a été d'évaluer et de cartographier le volume de ces captures accessoires. Cette analyse devait également permettre de caractériser le peuplement de l'écosystème du plateau guyanais, étude de la...

Late Winter Distribution of the American Plaice (Hippoglossoides platessoides) in St. Pierre Bank, 1978–90 ArchiMer
Moguedet, Philippe; Mahe, Jean-claude.
The late winter distributions of the American plaice (Hippoglossoides platessoides) in St. Pierre Bank (NAFO Subdiv. 3Ps) during the period 1978–90 were analyzed using catchesper- 30-min-tow data obtained during the French groundfish surveys which have been conducted annually in February–March. Water temperatures from surface to bottom recorded at the end of each trawling operation were used along with temperature recordings from a standard hydrographic transect. Largest temperature fluctuations occurred in the two upper depth ranges (0–99 and 100–199 m) and were assessed to be due to the great influence of the Labrador Current. Generally, American plaice was well represented in the Halibut Channel. During cold winters (1982, 1985–87, 1989 and 1990),...
