Since the beginning of the century, scallop fisheries in France have known successive phases of expansion and recession. Although a system of fishing licences has been implemented, the number of fishermen involved in the scallop fishery has increased and huge investments have been  made. The important fishing effortduring this period has induced a serions stock depletion, and output has dropped to less than 2 000 m.t. per year since 1986. Hence, the remunerations of capital and labour have dramatically decreased. As early as 1973, attempts have been made to use aquaculture methods for the management of  thisstock, following the successful Japanese model. Because of insufficient amounts of spat available from the wild, hatchery and nursery techniques have...

ABSTRACT This study evaluated the biomass gain, specific growth rate, absolute weight gain, and survival rate of the gastropod Pomacea dolioides cultivated in different stocking densities. To perform the experiment, samples were collected in March and June 2015. A total of 40 adult specimens were collected in the Jauary neighborhood (03°08′19.9"S, 58°27′32.5"W), municipality of Itacoatiara, AM, Brazil. They were kept in the laboratory for breeding to obtain the young P. dolioides, which were distributed into tanks containing 4 L of water and an aeration system, in three densities: 2.5 animals/L, 5 animals/L, and 10 animals/L, and were fed fish ration (34% gross protein). The specimens were measured for shell length and weight every fifteen days. The...
