February 4, 2021 — Resource management is a tricky thing. That’s especially true in the marine environment where things are so interconnected. Nutrients literally float from one area to the next and the larvae of spawning sea creatures similarly drift from place to place. Marine species do not abide by borders but are instead are a part of a larger ecosystem where things literally flow from one location to another.
For this reason, there are few marine species that are managed at a municipal level. Some, like lobster, are managed by the state – by Maine’s Department of Marine Resources. The DMR has jurisdiction over subtidal waters (those below mean low water) throughout the state. Others, like stripers, are managed by interstate groups like the Atlantic States Marine Fisheries Council. And others, like cod and haddock, are managed regionally by bodies like the New England Fisheries Management Council. They have jurisdiction over waters beyond three miles from shore classified as federal water.
So, what does that leave for the municipalities? That’s a seemingly tiny sliver of intertidal coast. But, this sliver often isn’t tiny at all. It is shallow and broad and supports a valuable array of shellfish species like soft shell, hard shell, and razor clams. While these species do move around as larvae, they are more likely to stay put than other more mobile creatures. For that reason, these are the resources that each town is in charge of managing under a system called co-management. This means that towns work with the DMR who helps to classify areas that are safe for harvesting in terms of water quality and also helps with enforcing statewide regulations.
