A study of zooplankton and ichthyoplankton was carried out from samples collected along the Senegal-Guinea maritime area on board Norwegian research vessel 'Dr Fridtjof Nansen' in November 2011. Nineteen groups were identified with a dominance copepods representing 68.5%. The Copepods included 35 species, where Paracalanus parvus dominant (21.5%). As to ichthyoplankton, 29 fish families encountered, Clupeidae (35.8%). They represented by Sardinella spp (98.0%) Sardina pilchardus (2.0%). An...
This study investigated variations of landings two key species, Sardinella aurita and maderensis, in Senegalese waters over a ten-year period (2004–2013). Using generalized additive models, it was found that fishing gear played major role explaining differences monthly for both species (51–71% deviance explained). Its effect more significant the southern part Senegal. Fishing effort (number trips) accounted only 4–18% variability landings. Purse seine (PS) most important contributor to...
We examined growth rates and reproductive characteristics of Sardinella aurita off Senegal other coastal areas over a 20 year period (1995-2014) to determine how they relate variations in environmental waters. Based on fish length-frequency data upwelling index, we found that S. recruitment tends occur during the periods most intensive (March-April Senegal). Peak reproduction corresponds low sea-surface temperature (in February or March). The sex ratio was remarkably consistent 30 study so...
For the first time in Senegal, assessments based on both stochastic and deterministic production models were used to draw a global diagnosis of fishing impact coastal demersal stocks. Based one national fisheries databases scientific trawl surveys data: (i) trends landings since 1971 examined, (ii) abundance indices 10 stocks estimated using linear fitted data commercial catch per unit efforts, (iii) stock carried out pseudo-equilibrium Fox Pella-Tomlinson Biomass dynamic model Bayesian...
Using catch composition data collected on individual fishing trips between 1990 and 2001, we study tactics strategies of the coastal demersal trawlers operating in Senegal. Types actions (tactics) are defined through fourteen stocks. units (strategies) according to they can use. These two typologies built using K Means method, a non hierarchical classification approach. As results, twelve six primarily identified. expert knowledge some gathered eight five finally considered discussed with...
Les villages de Mballing, Nianing, Pointe Sarène et Mbodiène situés sur la Petite Côte ont envisagé d'avoir chacun une Zone pêche protégée (ZPP) son terroir. pêcheurs définissent les ZPP base des savoirs empiriques qu'ils biologie espèces, mais aussi surtout moyens dont ils disposent pour assurer application règles gestion zone. superficies couvertes vers le large ne dépassent pas ainsi 2 km. recherches d'accompagnement montrent que l'étroitesse zones au pose problème pertinence quant à leur...

Demersal shrimp fisheries, which are not very selective, generate significant discards and / or bycatch, generally composed of crustaceans, fish molluscs different size classes.As part the implementation management plan for deepwater Parapenaeus longirostris in Senegal, selectivity tests Nordmore device were conducted.Thus, three grids characterized by spacings between bars (24, 28 30 mm) tested on experimental trawl Senegalese Economic Zone.Regardless spacing, Grid completely removed large...
In emerging countries, the consequences of stress remain undervalued. Stress in workplace is increasingly recognized as one most serious occupational health hazards reducing workers’ satisfaction and productivity, well increasing absenteeism turnover.1-3 At beginning, a heavy workload, lack recognition work done communication difficulties.4 There also need to deal with situations where people feel disarmed (suffering beneficiaries, war) or, on contrary, waiting without possibility acting for...
Cette étude vise à mieux faire connaître le fonctionnement écologique de l’aire marine protégée (AMP) Joal-Fadiouth via l’inventaire sa composition spécifique et la répartition spatiale faune ichtyologique. A cet effet, un suivi bioécologique a été mené durant les 4 saisons hydrologiques 2015 2017, au niveau 6 stations caractéristiques des habitats l’AMP, avec mêmes engins équipe pêcheurs. Les analyses statistiques ont effectuées l’aide du logiciel XLSTAT 2017. Au bilan, 120 espèces poissons...
