Last week, members of our team in the DFO Great Lakes Food Webs lab returned from a week-long voyage aboard the Canadian Coast Guard Ship (CCGS) Limnos for the first cruise of the Lake Erie CSMI field-year. We were joined by other interdisciplinary scientists and technicians from our federal research partners at Environment and Climate […]

“Night, when words fade and things come alive” – Antoine de Saint-Exupery.
One of the species the Lower Trophic Food Webs lab is responsible for monitoring in the Great Lakes is Mysis diluviana (previously called M. relicta which is native to Northern Europe), the Opossum Shrimp (order Peracarida, family Mysidae). For a member of the zooplankton, this species is quite large (up to 25 mm in length), and their common name comes from the females having a prominent brood pouch (a marsupium) between their thoracic legs. The body is very shrimp-like, with long antennae, stalked compound eyes, a large thoracic carapace in front of a long abdomen and a clefted telson tail.

Great Lakes Food Webs Science: WinterGrab II 2024
“What good is the warmth of summer, without the cold of winter to give it sweetness.” – John Steinbeck
This past week our lab once again sampled sites around Burlington Ontario in February for the WinterGrab II. In the Fall of 2021, a grass-roots group of US and Canadian Great Lakes scientists met to plan a set of standardized sampling for mid-winter across all of the Great Lakes.

The next science advice client that our lab at Fisheries and Oceans Canada (DFO) provides science advice to is related to our mandate under the International Joint Commission. While Environment and Climate Change Canada (ECCC) has many regulatory and conservation responsibilities, they are both our regular science collaborator in the Great Lakes, and also the Canadian agency lead under the Great Lakes Water Quality Agreement, so they are ultimately responsible for reporting out and moving forward restoration activities.

It is a truth universally acknowledged, that a scientist in possession of good data, must be in want of a paper (with respects to Jane Austin)
Though it is often hoped by students in aquatic sciences that a scientist’s duties involve mostly sampling in the field, the sad fact is that the vast majority of a scientist’s time is spent working on things which aren’t even data and writing, much less working on a boat.
So, What do Aquatic Scientists Work On in the Dark of Winter? Read More »
Time to celebrate a very busy and successful year for our Great Lakes Lower Trophic Lab research and monitoring activities. The 2023 year was the intensive field-year for the binational (US/Can) Cooperative Science and Monitoring Initiative (CSMI) for Lake Ontario. Fisheries and Oceans Canada (DFO) is one of the federal leads for this initiative and

Lake Huron CSMI 2022: Lake Huron Georgian Bay Cruise May 31- Jun 8 2022. The 2022 field year in the Great Lakes was focused on Lake Huron for Binational Cooperative Science and Monitoring Initiative (CSMI). After several years of disruption from Covid-19 restrictions, we were back onboard with a much closer to normal shipboard experience.
