    La pêche industrielle des poissons démersaux en Côte d'Ivoire. Généralités, localisation, homogéneité relative des zones de pêche ivoiriennes (2021)

    Description: This paper describes the fishery of Côte d'Ivoire and its evolution to the present day. The location of fishing off Côte d'Ivoire is specified for each area and each type of trawler. A comparison of productivity between the different areas shows disparities that allow to make clearer the repartition of effort of all types of trawlers in each area. The Côte d'Ivoire continental shelf is populated with demersal stocks of homogeneous densities.

    Standardisation des efforts de pêche des chalutiers ivoiriens et estimation de l'abondance relative dans les divers secteurs (2021)
    In:  http://aquaticcommons.org/id/eprint/7951 | 424 | 2012-03-11 08:53:59 | 7951 | Centre de Recherches Océanographiques, Côte d'Ivoire

    Description: The method developed by Robson (1966) is used to standardize fishing effort of Côte d'Ivoire trawlers whose size and power are very different. This method also allows the estimation of the relative abundances in the different fishing areas. The results obtained using 10 years data show that the entire Ivorian continental shelf can be considered as a single fishery unit. The relative fishing power of vessels is well correlated with gross tonnage, brake horse power and length of the vessel. The obsolescence of the trawlers affects their fishing power.

    Estimations des potentiels de pêche des stocks démersaux ivoiriens par les modèles globaux. Effets de la prolifération du Baliste (Balistes capriscus) (2021)

    Description: Statistical data (1959-1977) of the trawling fishery off the continental shelf of Côte d'Ivoire has been fitted to the Fox (PRODFIT) global model. Owing to the proliferation of baliste (B. capriscus) since the years 1971-1972, data were divided into two groups. Maximum Sustainable Yield MSY: PMMC in the text), for the whole of commercial species in the continental shelf, decreased from 8800t to 5900t between the two periods; the difference represents balistes potentialities at bottom level. The model has also been fitted to data which concern Sciaenidae coastal community and Sparidae community which are parts by the 50 m isobathe. Deep layer (50-120m) MSY is at 2350t during the whole period of study. Until 1977, this potentiality was never reached, because of the low productivity of the Sparidae community.

    Description: One additional Chalci campaign that, in line with the previous Chalci campaigns 78-01, 78-02, and 79/01, has as its major objective the trawl exploration of the Ivoirian continental shelf at the depth of 10 to 120 metres.
