Some aspects of the biology and of the ecology of larvae and post-larvae of lobster (Homarus sp) are summarized in order to illustrate the purposes of retocking trials carried out on each side of the Atlantic Ocean. Canadian and American experiments are analysed : the conclusions that can be drawn as well as those that cannot be drawn from these experiments are discussed. Present methods of rearing used in U.S.A., Canada and France, and the main problems (prevention of cannibalism, nutrition, diseases, etc.) are discussed. Results of American and French research carried out in order to obtain animals witch special morphological characteristics are given. These animals could be utilised for assessing the impact of restocking attempts
