  “The Gulf of St. Lawrence has never been explored with the type of technology we have,” Oceana’s science director, Robert Rangeley, said in . In the 17th century, the Saint Lawrence River became the major maritime gateway into Canada, playing a key role in the exploration and development of the North American continent. Flowing out of the Great Lakes, it continues for over 1, km, including km along the Canada-U.S. boundary, before discharging into the Gulf of Saint Lawrence.

The narrow size range (33 to 41 cm.) of the large, mature redfish taken in the Gulf of St. Lawrence is due to a southerly drift of larvae away from the spawning area, to an accumulation of old, mature fish, and to a differential distribution by sizes.

Lawrence with tales from the sea. For more than a week, Oceana Canada, Fisheries and Oceans Canada and Alexandra Cousteau explored and documented never-before-seen habitats off the coasts of Nova Scotia and Quebec. We dived to the seafloor to depths of up to m using one of the most advanced technologies available for deep-sea oceanographic exploration.

A significant increase in redfish stock in the Gulf of St. Lawrence is spurring an interest in reopening redfish harvesting after a moratorium has been in place for nearly 25 years. The provincial government wants to ensure Prince Edward Island gets its fair share of the redfish quota when Ottawa reopens the industry in the future.

Located in eastern Canada, the Gulf of St. Lawrence owes many of its unique characteristics to its geography. Sea water flows into and out of the gulf through only two channels. Currents and tides sweep cold, Arctic seawater through the narrow Strait of Belle Isle in the north. In the south, the wider Cabot Strait admits warmer water from the Atlantic Gulf Stream.

Acadian redfish in the Gulf of St. Lawrence (unit 1) and the Laurentian Channel (unit 2) were previously assessed separately but from a joint assessment was conducted as there is evidence that the two units belong to the same biological unit.

However uncertainty remains as to exchange with adjacent units (Valentin et al, ). Parasites have been considered as natural biological tags of marine fish populations in North America for almost 75 years. In the Northwest Atlantic, the most studied species include Atlantic cod (Gadus morhua), Atlantic herring (Clupea harengus) and the redfishes (Sebastes spp.).In the North Pacific, research has centred primarily on salmonids (Oncorhynchus spp.).

The marine species identification guide for the St. Lawrence was first published in Since then, it has been reviewed several times and presented under various formats.

This Internet version is the most current one avaliable for the invertebrates. The fish species guide however has been entirely validated and revamped in and is.
