February 1, 2018 — Conservation pays off.
For years, lobstermen in the Gulf of Maine have been returning large and egg-bearing females to the water, instead of selling them for a short-term profit. The long-held practice, called “v-notching” because the females’ tails are marked to alert other lobstermen of their fertility, has kept the lobster stock healthy. A 5-pound lobster can produce another thousand lobsters in its lifetime, fisheries scientists say. A 1.5-pound lobster produces about 100. The last several years have been some of the most profitable in the industry’s history.
Now, it looks like those years of self-restraint are going to help the industry weather a new challenge — climate change.
In a report released late last month, scientists predicted the Gulf of Maine lobster population will drop as much as 62 percent over the next 30 years. The change is coming as the waters warm, making it more difficult for baby lobsters to survive. That’s the bad news.
The good news is that the conservation efforts used over the past several decades by lobstermen from Rockport and Gloucester to the state of Maine fostered exponential growth in the lobster population. Ironically, the warming waters also helped, until the temperature rose past a healthy level for young lobsters.
