ABSTRACT
The effect of level salinity and temperature on Penaeus kerathurus(crevette grise) eggs hatching rate was the object of this study from May to July 2012 at Aquasol Company based in Kribi, in the Ocean Division of the Southern Region of Cameroon. The general objective of the study was to add value to the mastering of the optimal production conditions of Penaeus kerathurus larvae. More specifically, emphasis was laid first on the effect of level salinity on eggs hatching rate; secondly, the evaluation of the effect of level temperature on the Penaeus kerathurus eggs hatching rate; and finally the examination of both the level of salinity and temperature effect on the Penaeus kerathurus eggs. A total of 2700 eggs with 96 % Lire la suite...

ABSTRACT
Effect of salinity on survival and growth performances of marine shrimp Penaeus notialis fingerlings was carried out between April and September 2011 at AquaSol structure in IRAD of Kribi in Cameroon. A pregnant female with total weight 32 g and 15 cm total length has been collected in the natural environment by a fisherman using a bottom thread. Thirty 20 days old post larvae (PL20) born from this progenitor were seeded in triplicate in plastic bins at 15‰ (S0), 20‰ (S1), 25‰ (S2) and 30‰ (S3) salinity. Survival rates were high regardless of salinity. However, the higher survival rates (94.44 and 96.67%) were respectively recorded from 25 ‰ and Lire la suite...

INTRODUCTION
It is now accepted that the development of fish farming currently compensates for the stagnation of fishery catches while the market demand continues to increase [1]. The
development of fish farming relies on an active diversification of farmed fish species. A diversification based on the farming of native species could reduce the environmental impact of fish culture and could better fit to needs of local markets. Such development could also favour a more integrated local economy. It is in this context that new species in many areas of the world were domesticated especially in Amazonia [2] and in the Mekong River Bassin [3]. Moreover, Lire la suite...

INTRODUCTION
The domestication of new species of fish aquaculture inherent diversification is a recurring issue [1]. All cultured aquatic species have been domesticated since the early twentieth century [2]. These diversification of species produced corresponds to situations and varied objectives, including: the need to cover traditional markets (niche market) for which demand is not satisfied, using species with very high growth potential in order to reduce production costs and the risks associated with cycle times rearing [3], as well as the necessity to eliminate the use of the wild fingerlings for domestication purposes [4].
