Shellfish Plan Spans Chilmark and Tisbury

With nitrogen pollution a perpetual concern for Vineyard waterways, two towns are hoping that a shellfish experiment will be the latest puzzle piece to fall into place.

Voters in Chilmark and Tisbury will be asked at their respective town meetings next week to fund pilot programs aimed at reducing nitrogen levels in two locations: Chilmark Pond and Lagoon Pond. Through the funding and a partnership with the Martha’s Vineyard Shellfish Group, test reefs of noncommercial oysters will be cultivated, in addition to beds of native ribbed mussels.
