Canada's DFO proposes harvest tweaks to sustain Atlantic lobster catches

Federal researchers from the Department of Fisheries and Oceans (DFO) have released a report outlining a suite of modest changes to lobster harvesting practices aimed at countering declining catches in the Atlantic Canadian fishery. The study recommends shifting the fishing season to earlier months to avoid warm periods when lobsters molt and mate, increasing the maximum legal size to preserve larger, more fecund females, and providing additional protection for egg‑bearing lobsters. While modest reductions to trap limits are deemed unlikely to have a meaningful impact, shortening season length is identified as an effective control on exploitation.

Co‑lead scientist Adam Cook emphasized that the current lobster stock is healthy but faces pressures from climate‑driven warming waters that are pushing the species northward. He said the goal is to offer proactive advice so the industry can discuss potential adjustments before any decline occurs. The department clarified that no management measures will be changed solely on the basis of this study; the findings are intended to inform future decisions should industry or stock conditions warrant them.
