Statistiques de pêche en Lagune Aby (Côte d'Ivoire): la pêche a l'epervier (1988)

Cast net fishing is a relatively important socio-economíc activity in Aby lagoon. About 516 fishermen practice this activity for an annual total production estimated at 336 millions CFA, which represents 54,000 CFA per month. The catches are essentially composed of Cichlidae (88,7 %) and Mugilidae (2,8 %). The annual production represents 15 % of that of other types of gears used (beach seines, syndicat seines and gill nets).

La pêche artisanale en lagune Aby (Côte d'Ivoire): analyse des captures en 1988 et 1989

The exploitation of fish stocks in Aby lagoon was marked by an increase of total fishing effort, yields and therefore by the increase of total production. Fishing effort evolution was due to: the increasing of the number of beach seines which has increased from 26 in 1987 to 32 in 1988, the reappearance of syndicat seines and finally the importance of fishing teams activity.

Concentrations en mercure dans les muscles de thons albacores (Thunnus albacares) du golfe de Guinee (1987-1988)

Samples of albacore tunny-fish (Thunnus albacares) caught from East Tropical Atlantic areas have been analysed in white and red muscles in order to determine the concentration of mercury. The results show that there are no significant differences between the mercury concentrations in the white and in the red muscles, and that a significant correlation exists between the mercury concentrations in the two types of muscles.
