Introduction
I am fluent in biology, ecology and the sustainable management of marine biological resources, whether exploited or not. The ecosystem approach to fisheries, the protection and recovery of degraded coastal habitats are among my concerns. The identification criteria and the various stages leading to the creation of a Marine Protected Area are taught and highly recommended to fisheries biologists, as well as to stakeholders and other local populations. The wider the range of scientists in the mari

To find out more about the exploitation status of the fish species Brama brama in Côte d’Ivoire, population dynamics were undertaken with Logiciet FiSAT II (FAO-ICLARM Stock Assessment Tools) software (version 1.2.2). Samples were collected from artisanal marine fishermen landing at the Abobodoumé pirogue wharf, Abidjan. The study of this populatio...
The governance of coastal and marine resources remains a complex socio-ecological
endeavor in many African countries, but women are leading the way and demonstrating
a pathway for food fish security through rights-based co-management of shellfisheries in
estuarine and mangrove ecosystems in West Africa. We report comprehensively, for the
first time...

We report comprehensively, for the first time...
Opportunity may exist to replicate and expand shellfish livelihoods based in mangrove ecosystems, which can provide a cheap source of protein and micronutrients to coastal dwellers across West African coastal countries. This country assessment is aimed at gathering data on the scale and scope of shellfisheries and shellfish-based livelihoods associ...
Le lac de barrage Solomougou, créé en 1973 à des fins agricoles, est exploité de nos jours pour les activités halieutiques. La présente étude y a été conduite en vue d’étudier sa diversité ichtyologique. Les captures des pêcheurs ont été analysées de janvier à décembre 2019. Les paramètres étudiés sont la richesse spécifique, les abondances spécifi...
The Solomougou dam lake, created in 1973 for crop irrigation, is nowadays used for fishing activities. This study was conducted in order to understand the ichthyological diversity in this fishery. So, fishermen’s catches have been analyzed from January to December 2019 in order to identify fish species and to calculate their specific and relative a...
The stomach contents of 697 specimens of Makaira nigricans were studied to examine the diet of this species. The overall vacuity rate was calculated
as 64.84%. This rate, relatively low during the great cold season (June to August), varied from 51.78 to 55.88%. The 16-prey species identified
consist of a mollusc (Illexcoindetti) and 15 fish species...

The present study evaluated the performances of two larval production techniques of Oreochromis niloticus. The experiment was conducted on two batches of broodstock, a two-week-fed (G1) and a one-week (G2) batch reproduced separately in two 400-m2 ponds containing five (5) happas of 10 m2 each. Each happa contained 20 males for every 60 females. Fi...
The catches of Rouvettus pretiosus, landed by artisanal marine fishermen at the different wharves of Zimbabwe, Abobodoumé and San-Pedro (Côte d'Ivoire), between 2000 and 2014 were studied in relation to fluctuations in marine seasons. . During the Great Hot Season (GSC) the average temperature was 26.13 ° C. With a fishing effort (Ep) of 376 canoes...
A study of Synodontis punctifer (family: Mochokidae) of Taabo Lake
was conducted from October 2015 to September 2016. This was carried out
so as to evaluate its quantity (biomass) caught by fishing and also its
morphological characteristics. The fish were caught using gillnets at 4 sites of
the lake and different measurements were made. The fishing...
The technologies used in fisheries became more efficient, just to meet the needs of a galloping population. That significantly affects the sustainable management of living resources, including major tunas (Thunnus albacares, Katsuwonus pelamis, Thunnus obesus). To alert international opinion on the level of exploitation of these fish species, a com...

The goal of this study was to investigate the effect of salinity on the activity of the main transmembrane protein involved in osmoregulation in the gills of tilapia Sarotherodon melanotheron heudelotii from a hypersalé estuary (Saloum, Senegal). In a controlled environment, juveniles of S. m. heudelotii initially high TO 0.3 PSU in fresh water (ED...

This study focuses on the small-scale artisanal fishery that captures blue marlins (Makaira nigricans) in Cote d'Ivoire. The sizes, weights and quantities landed of this species were approached according to the marine seasons and fishing areas. These fishermen, mostly Ghanaians, use canoes (12 to 17 m) as craft, and drifting gillnets (4800 to 5400...
La reproduction de Heterotis niloticus a été étudiée de juin 2013 à
mai 2015 à partir des échantillons provenant de la pêche artisanale de la
rivière Agnéby. Au total 498 spécimens dont 269 femelles et 229 mâles ont
été examinés. La sex-ratio est en faveur des femelles (1 : 1,17; X2= 3,21 ; p >

The essential oils and 70% ethanol extracts from leaves of Hyptis suaveolens and Lippia multiflora were tested on two multi-resistant bacterial strains. The results of the tests in agar and liquid suspension show a higher antibacterial activity for essential oil of Lippia multiflora and for ethanol extract from Hyptis suaveolens after essential oil...
The objective of this study was to evaluate the antifungal potency of the essential oil of tea of savanna (Lippia multiflora) on three fungal strains. The essential oil is extracted of Lippia multiflora by steam distillation and the antifungal activity in vitro was investigated on Apergillus flavus, Asperguillus Niger and Fusarium sp species. This...
The ethanol extract and ethyl acetate fraction of Mangifera indica kernel seed cake inhibited the growth of Staphylococcus aureus and Pseudomonas aeruginosa. The bioactive compounds were isolated and identified by NMR, UV and mass spectrometry as methyl gallate, gallic acid and penta-O-galloylglucose. Theisolated methyl gallate and penta-O-galloylg...

A study has been carried out on the different sizes of the fish captured, so as to highlight their variations over the years. On t...
A 90-day feeding trial was conducted with Nile tilapia (Oreochromis niloticus) to assess the growth, body composition and cost–benefit. Tilapia juveniles weighing 4.35–4.38 g were grown in ponds and reared on an industrial commercial diet (as reference) and on two practical diets. Formulated diets were designated as CBS (cocoa bean shell, corn bran...

Fractionation of the ethyl acetate fraction of the ethanolic extract of the dried powdered leaves of Santaloides afzelii (Connaraceae) on silica gel column chromatography afforded gallic acid and two flavonoids glycosides identified as quercetin-3-O-rhamnoside and myricetin-3-O-rhamnoside. Their structures were elucidated by 'H and 13C-NMR data and...
Les taux de capture standardisés sont souvent utilisés comme indices d’abondance relative dans l’analyse des données de capture. La pêcherie artisanale maritime en Côte d’Ivoire a été très active entre 1988et 2007 en débarquant aussi bien des grands thonidés, les thonidés mineurs que les poissons porte-épées à l’aide de filets maillants. Dans le pr...
Scomberomorus tritor est une espece de la famille des Scombridae debarquee quotidiennement au port d’Abidjan par les chaluts doubles. Le regime alimentaire de cette espece de thonides mineurs capturee par les chaluts pelagiques est etudie en fonction de la taille des specimens et des saisons marines. Les estomacs de 832 individus (14 - 114 cm de lo...
