Prises accessoires des chalutiers et distribution des larves de lancon (Ammodytes sp.) dans l'estuaire et le golfe du Saint-Laurent
By F. Grégoire and C. Lévesque
Abstract
Sandlance is a very important member of the marine ecosystem of the Estuary and Gulf of St. Lawrence. It is the prey of several species of marine fish, birds and mammals. Despite this importance, there is few data concerning its biology and the structure of the stocks. There is no direct fishery on this species but sandlance is a by-catch of the shrimp trawlers or those having fished for cod or redfish. These by-catches, gathered by the Observer Program between 1990 and 1997, and the larval abundance and distribution observed during the mackerel egg survey in the southern Gulf of St. Lawrence are described in the present document.
