Estuary and Gulf of St. Lawrence marine ecosystem overview and assessment report. Can. Tech. Rep. Fish. Aquat. Sci. E: vii + p. The report’s main objective is to provide a descriptive overview of the components, structure and functioning of the Estuary and Gulf of St. Lawrence ecosystem as well as a preliminary. A Complementary Tool With this in mind, the Species at Risk and Biodiversity team of the Maurice Lamontagne Institute decided to produce a field tool to assist biologists in identifying and comparing the marine species of fishes and invertebrates that may be encountered in the Estuary and Northern Gulf of St. Lawrence.

All but one of the nine non-native marine species that established populations in the southern Gulf of St. Lawrence (sGSL) in the past decade initially invaded the sGSL via coastal and estuarine waters of Prince Edward Island (PEI) (see Fig. 1).Almost half of these non-native species are tunicates, and all but one of the recent tunicate invaders of the sGSL still occur only in PEI.
Map of the 84 sampling sites. Detailed map of the 84 sampling sites in Estuary and Gulf of St. Lawrence (EGSL). Red circles represent stations where . DFO research survey data indicate that the northern shrimp is widespread in the Estuary and in the northern Gulf of St. Lawrence (Figure 2). It is distributed over more t km2 at depths from to m, with more than 80% of the biomass concentrated in channels between and m, at bottom temperatures ranging from to °C.

ABSTRACT: The entire Great Lakes watershed drains through Lake Ontario and flows into the St. Lawrence River near Cape Vincent, New York. The St. Lawrence River then flows northeast through Quebec and Ontario and into the largest estuary in the world, the Gulf of Saint Lawrence. The St. Lawrence. The Gulf of St. Lawrence is an incredibly diverse and complex marine and estuary ecosystem and is one of the largest of its kind in the world. It’s a busy and productive part of the ocean that has unique species, some that live there year-round, and others, like whales, which travel long distances just to visit this special spot. The area is made up of freshwater from the. Estuary and the Northern Gulf of St. Lawrence (Figure 2) at depths of to m (Figure 2) with more than 80% of the cumulative Northern Shrimp biomass found between and m in areas with a bottom temperature of °C to °C (Figure 3).
