Northern shrimp populations in the Gulf of St. Lawrence, Canada, are facing alarming threats, warn scientists. The delicate crustaceans are struggling to adapt to warming waters and decreasing oxygen levels, leading to a significant reduction in their habitat.

A recent scientific update from Fisheries and Oceans Canada sheds light on the dire consequences of ocean warming on northern shrimp. The agency reports a concerning trend towards the shrinking of suitable habitats for these crustaceans.

Rising Temperatures and Decreasing Oxygen Levels

The core issue lies in the increasing water temperatures, particularly in the deep water layer where northern shrimp predominantly reside. Over the past 13 years, scientists have recorded an average temperature increase of 1.8 degrees Celsius in this layer, indicating a significant warming trend.

Moreover, this warming trend correlates with a decline in oxygen levels within the water. A 70% decrease in oxygen levels has been observed in the Gulf of St. Lawrence over the past five decades, further exacerbating the challenges faced by northern shrimp.

Declining Shrimp Quantities

Fisheries and Oceans scientists have unequivocally stated that there is a noticeable decrease in shrimp quantities within the Gulf. While there’s currently no immediate fear of complete disappearance, the situation is undeniably precarious.

Fishermen, unsurprised by these findings, have long been aware of the mounting challenges confronting northern shrimp populations. Many attribute the decline not only to environmental factors but also to the increasing presence of redfish, the shrimp’s primary predator, in the region’s waters.

Government Action and Industry Response

In response to these alarming developments, a meeting has been scheduled between federal Minister of Fisheries Diane Lebouthillier and representatives from various fishing associations. This gathering aims to address the concerns raised and explore potential solutions to safeguard both shrimp populations and the fishing industry.
