Resumo: 	This these is the result of several years of investigations conducted on the common prawn Palaemon serratus in the Roscoff (northern Brittany) and Yeu (bay of Biscay) sectors of the French Atlantic coast.    Following a description of the fishery and fishing strategies, it deals with the species biological aspects, focusing on growth, lifespan, sex-ratio and breeding. Hypotheses on the reasons for apparent variations in interannual abundance are drawn up and compared with field observations.   The second part is devoted to production experiments in a controlled environment (hatchery), explaining how larvae are obtained and their development and survival with respect to food, density and physical parameters like salinity and temperature. The link between nucleic acid changes and larval development is then analysed.   The third part focuses on the rearing of post-larvae in order to produce adults, examining the variables which foster fast growth. After analysing the diet and nutritional needs, the influence of the protein content on weight gain, the way feed is presented and the addition of compound feeds are examined.   The last chapter deals with problems of disease due to the ciliate Ascophrys rodor which P. serratus are exposed to in shrimp farms.
