Abstract
Mugil curema, known as white mullet, was one of the fish species encountered in the fisheries landings of the Saloum Delta. In this study, the morphometric parameters and the reproductive biology of this species were studied as well as the influence of environmental parameters on its reproduction. Experimental fisheries were carried out monthly in the Saloum Delta. The fish were caught using surface drift nets. The captured individuals were measured and weighed. The gonads were collected to determine the sex and the stages of sexual maturity. Out of a total of 406 individuals sampled in the Saloum Delta, 306 females and 100 males were identified, no individuals of undetermined sex were obtained. The sex ratio was globally in favor of females. Individuals in this study ranged in size from 102 to 385 mm and weight from 34.9 to 395 g. The allometric coefficient b was equal to 2.40 and indicated a negative allometry. The exploitation of the monthly IGS results indicated that reproduction was in April, May and June. The size at first sexual maturity indicated that the males matured at a size of 220 mm, lower than that of the females 226 mm.
Highlights
Fisheries and aquaculture remain a key resource for hundreds of millions of people around the world in terms of food, nutrition, income and livelihoods
The aim of this study was to contribute to the improvement of the management of the M. curema fishery in the Saloum Delta by evaluating the reproductive parameters and the environmental impact in order to ensure a sustainable use of this resource for the benefit of the coastal populations
The average pH value (8.02) indicated that the waters of the Saloum Delta were basic throughout the year with a pH higher than 8 except for the months of June, July and August when the pH was equal to 7.67; 7.90 and 7.98 respectively
Summary
Fisheries and aquaculture remain a key resource for hundreds of millions of people around the world in terms of food, nutrition, income and livelihoods. Recent reports by high-level experts, international organizations, industry and civil society representatives highlight the significant contribution that oceans and inland waters can, and especially will in the future, make to the food security and nutrition of a global population expected to reach 9.7 billion people by 2050 (FAO, 2016). In Senegal, one of the world's most fish-rich regions, the fishing sector is growing steadily and plays a vital role in the national economy. This country has geographical and climatological advantages that give its coastline a reputation as a very productive area of the West African coast.
