The Zone C Lobster Hatchery
From 2004 – 2009 the Zone C Lobster Hatchery produced hatchery-raised juvenile lobsters for resettlement in local areas with depleted stock. Having successfully demonstrated that this is feasible, the current focus is on continued monitoring of survival at the resettlement sites. This research is in collaboration with Dr. Rick Wahle, University of Maine, and was supported by Maine Sea Grant.
Dr. Wahle’s research results show that there is evidence of long-term accumulation of hatchery-reared lobsters over several years of seeding at the two release sites on the western side of Zone C. Preliminary examination of growth rates of hatchery-reared lobsters suggests that they reached about 30 mm carapace length by the age of 3 years. We will post further findings as they are released.
Other hatchery research highlights of the final 2009 growing season included:
- Releasing 75,100 Stage IV lobsters on 32 different sites in the Zone C area.
- Releasing 3,400 Stage V lobsters on the research sites.
- Hosting several research projects for different principal investigators from the US and Atlantic Canada.
Alewife Research Project
In 2006 Davis Conservation Foundation supported an Alewife Research Project under the direction of Ted Ames, the question to be examined was: “Could alewife declines have facilitated cod stock collapses?” This investigation was closely related to Ted’s research into Gulf of Maine cod stock. Using historical and paleo-limnological approaches his team explored the potential historical link between cod and alewife in Penobscot Bay and Muscongus Bay.
Major Research Workshop/Conference
In April 2009 Maine Center for Coastal Fisheries hosted a major research workshop/conference: “Exploring Fine-scale Ecology for Groundfish in the Gulf of Maine and Georges Bank”, to bring together biologists, oceanographers, fisheries managers and fishermen to discuss spatially explicit fisheries management in the Gulf of Maine. This event was co-produced with the Gulf of Maine Research Institute, Maine Sea Grant, Maine Department of Marine Resources, and University of Maine.
