Positive signs in newest capelin stock assessment, but the tiny fish is still in the critical zone
“The capelin were in very good condition in the fall. That meant they’re longer and heavier than average. There’s lots of zooplankton, especially large zooplankton in the ecosystem,” said Hannah Murphy, a DFO research scientist and lead stock assessor. “We also had an increase in our larval abundance index this year, which is great. Larval survival is related to recruitment in capelin, so the more larvae we have and the more that survive, it’s better for the capelin stock.” Murphy said a full capelin acoustic survey happened over 2022, the first since 2019 due to the pandemic in 2020 and vessel availability in 2021. But the positivity ended there. This year, for the first time, the DFO has come up with a limit reference point for capelin. It’s set at 640 kilotons, the weight of fish in the water, and marks the boundary between the cautious and critical zones. >click to read< 17:32
