Proceedings from a scientific workshop on marine mammals, their habitats and food resources, held in Mont-Joli (Quebec) from April 3 to 7, 2000, within the context of the St. Lawrence Estuary Marine Protected Area project.

This manuscript reports on a scientific workshop on the marine mammals of the St. Lawrence Estuary held at the Maurice Lamontagne Institute in April 2000. The purpose of the workshop was to make a scientific assessment of the need for a marine protected area (MPA) in the St. Lawrence Estuary to protect marine mammals, their habitats and their food resources. Present and potential problems faced by marine mammals, arising essentially from human activities in the vicinity, were debated. The participants were then able to prioritize these various problems and weigh the adequacy of the MPA proposed boundaries. Disturbance, contamination and lack of knowledge were identified as the key problems. Finally, the participants determined that given the magnitude of the problems encountered by marine mammals, the establishment of the MPA was justified and indeed essential to the protection of these animals and their habitats.

Fishing season for snow crab (Chionoecetes opilio) is short. This results in an overabundance of fresh crab in spring. Snow crab is rarely available off season and in major cities markets. Holding live unfed snow crab would extend the period of availability beyond the fishing season. This report reviews our knowledge of the biological requirements of snow crabs and suggests handling and transport procedures as well as live-holding techniques. Snow crab survival in holding facilities depends on careful handling on boats and during transportation. Crabs should never be exposed to water temperatures over 10 °C or to salinities below 22 ppt. Live-holding can be carried out at sea using modified fishing gears, higher survival rates being obtained in deep cold water with high salinity. In land-based facilities, excellent results have been obtained for a 3,5 month period at 0 °C. Under these conditions, quality of flesh is high and mortality rates are low. There is a need for information on optimal holding densities and on tolerance to metabolic wastes and low dissolved oxygen concentrations. To make for this lack of knowledge, we review current practices in lobster holding facilities.

From a biological perspective, Atlantic cod rearing would appear promising. Atlantic cod can tolerate a wide range of environmental conditions and the production of larvae and juvenile cod from brood stocks does not present major problems. Nevertheless, the production of juvenile cod could be enhanced should we have a better knowledge of the nutritional requirements of the larvae. Little information is available on the mortality rate of cod in on-growing facilities. In Québec, the scarcity of large-size cod and decreased catches of wild cod would suggest that cod farming should be considered as a complement to harvest fisheries. However, prices are also influenced by international markets.

A review of the snow crab, (Chionoecetes opilio), fisheries in the Gulf of St. Lawrence and around Cape Breton Island reveals a paradoxical array of responses to the same management regime; production and abundance appear to have increased under heavy fishing pressure in one stock, remained stable in another, while a third collapsed. Although exploitation is focused exclusively on mature males and high fecundity levels appear to have been maintained, recruitment has been unpredictable. We discuss the possible roles of various abiotic and biotic factors as phenomena responsible for the recruitment trends. Presently, the incongruous nature of snow crab population dynamics, as manifested under exploitation, has preempted recruitment forecasting and confounded effective management.
