    Description: On tables 1 to 12, daily beach surface temperatures are presented. These temperatures are also ploted on figures 2 to 5 in daily values and in 7, 15, 30 days means. Salinity variations are less important than these of temperature (Fig. 6, 7). It follows that during upwelling period, variations of dynamic height anomaly are closely correlated with temperature (Fig. 6 and 8).

    Marquages de Penaeus duorarum notialis en Côte d'Ivoire. 2 - Migrations et mortalités (2021)

    Description: Petersen disc tag marking experiments confirm the influence of animal size and marking time on the recapture rate. Westward migrations occur, probably following the Ivorian undercurrent. Catchability coefficients have been evaluated for the Grand-Bassam fishing ground and tentatively extrapolated to the other fishing areas. The extrapolated non weighted coefficient for the entire fishing areas is q=0.00069/fishing day for an area of 390 miles. The instantaneous coefficient of residual mortality X taken as a first and possibly slightly overestimated value of M the natural mortality, has been estimated at 0.155/month, strongly corroborating Berry's results (1967). This value is however much smaller than that given by earlier authors. It is suggested that q could have a higher value during the very first weeks of exploitation at sea, when the juveniles are concentrated near the lagoon outlets.

    Description: The Petersen method was used to make growth assessments from experimental data collected during 1966-67 and 1969-70. The parameters K and L ∞ were calculated from the Von Bertalanffy growth curve. There was very little difference between the two years although growth in 1969 appeared slightly greater. A comparison of our results in Côte d'Ivoire with those from Senegal and Gulf of Mexico showed that the greatest growth occured on the west African coast and especially off the Côte d'Ivoire.

    Contribution à l'écologie de quelques taxons du zooplancton de Côte d'Ivoire. 2 - Dolioles, Salpes, Appendiculaires (2021)

    Description: The seasonal variations of vertical distribution and abundance over the shelf are investigated for Doliolids, Salps and Larvacea. The 3 groups present many similar ecological features. Two maxima of abundance occur during the little and main cool seasons. The second maximum is usually the most important, except for Salps. The 3 taxons inhabit more superficial layers in cool than in warm seasons. This allows them to follow the phytoplankton maximum which drifts near the thermocline during the warm season. Pelagic Tunicates come back to the phytoplankton enrichment areas by the deeper Ivorian under-current. A relationship between the vertical distribution pattern and the life cycle (sexual or asexual generation) is suggested.

    Description: The warm season is the abundance period of the planktonic larval stages of Decapod Crustacea and of Lucifer faxonii in Ivoirian waters. Two or three maxima occur each year during the enrichments interrupting the warm and oligotropic season: February (small upwellings), June - some years - (first rains) and September - November (flood of rivers, end of cold season). Vertical distribution follows seasonal variations and varies little among the taxons. In a general way, Decapod larvae and Lucifer inhabit superficial layers in cold season and sink down during the warm season. It allows them to follow the maximum of primary production. Lucifer faxonii is breeding almost the year long. Breeds succede at rate of 3,7 weeks approximately.

    Description: Euphausiids vertical distribution on the Côte d'Ivoire continental shelf during different seasons, average zonal distrubution, mean distance to the shore, and seasonal variations in abundance computed for five years, suggest that the appearance, and the shifting of euphausiids across and along the shelf are related with the variations of the distance from the shore of the ivorian under-current. The author reports that Nyctiphanes capensis has not been found in the region.

    Description: Spawning of bonga (Ethmalosa fimbriata Bowdich) takes place in polyhalin waters (Sppt. 〉 5ppt.). Migrations of young fish were studied by the mean of length data observed in different points of the lagoon from the artisanal fishery. Bonga remain 4 months in the hatchery (6 cm), before they expand in the whole lagoon until the age of 9/10 months. After this expansion phase, the fishes come back to the spawning fields (spawning length: 14/15 cm). Postspawning fishes leave the lagoon. Between birth and spawning, bonga are not affected by salinity changes, but reproduction occurs only in waters where salinity is higher than 5ppt.

    Description: Ecology and dynamics of juvenile pink shrimp Penaeus duorarum were studied from weekly sampling in the Abidjan lagoon system. After a brief description of biogeography and principal features of climate, hydrology of Ebrié lagoon and Adiopodoumé bay were considered. Shrimp distribution were connected with the main environmental factors. Precise work was done in Adiopodoumé bay, especially concerning the succession of age classes, their growth on the nursery grounds, seasonal variation in abundance, size and distribution, in relation to environmental factors. These results, and former knowledges, allowed us to propose a general pattern for pink shrimp life history in Côte d'Ivoire.
