As oyster season in Tisbury Great Pond comes to an end, the Chilmark shellfish department is already planning for next year’s harvest.

At a selectmen’s meeting Tuesday, shellfish constable Isaiah Scheffer noted a strong harvest in the pond and asked that the season end immediately. He also plans to relocate oysters from a contaminated area to the north, where shellfishing is not allowed, to cleaner waters.

Mr. Scheffer said the area north of a sandbar known as Big Sandy was paved with oysters that can’t be harvested due to high bacterial counts in the water. The uncontaminated area south of the bar will remain closed to shellfishing for at least three months as the relocated oysters clean themselves out.

The constable explained that all oysters start off as males but then turn into females, a fact that surprised even some of the veteran fishermen in the room. The oysters north of Big Sandy are all different sizes, he said, and likely included many females.

“So just to have more females up to the other end of the pond is a good thing,” Mr. Scheffer said. “When they release their eggs, hopefully we will get another good seed set. And then whatever’s there the guys can fish on next year.”

The selectmen unanimously approved both the season closure and the relocation.

In other shellfishing news, oyster farmer Matthew Mayhew plans to station an electric upweller at his father’s dock on Nashaquitsa Pond. The upweller will contain baby oysters and provide a steady flow of water and nutrients to keep them growing. The selectmen opened a brief public hearing and approved the request, with Mr. Mayhew’s father, selectman Jonathan Mayhew, abstaining. The project still requires state approval, but fisherman Donald Poole and others offered their support.

“It’s infinitely easier to be able to tend your stuff on the end of your dock than to have to go out, get to the middle of the pond if you forget something or something breaks or you drop something overboard,” said Mr. Poole, who also keeps an upweller in Chilmark.

There was discussion about planned improvements to the Menemsha comfort station, the topic of a public visioning session last year. Selectman Warren Doty said renovating the station could cost around $75,000, but he wanted the selectmen to decide whether to rebuild it entirely. Voters allocated $10,000 for a needs assessment and design services for the station in November.

The station already has enough space, Mr. Doty said. Renovations would likely include a new roof and shingles, new windows, an additional toilet stall, urinals and an outdoor shower.

“As a board we need to keep this issue going,” Mr. Doty said. “We need to make some progress.” The selectmen agreed to ask the town planning board for a list of possible consultants and to resume the discussion at their next meeting.

With the arrival of spring, thoughts have quickly turned to summer and the large crowds that flock to Menemsha for seafood and sunsets on the beach. New paths and crosswalks are in the works, along with the widening of Basin Road where it curves down to the harbor.

Jane Slater, who lives and owns a business in Menemsha, advocated for a crosswalk at the intersection of Basin and North Roads. She also drew attention to a sharp curve farther north. “That’s where the problem is, that’s where everyone panics,” she said. “I think it’s a waste of energy and time to do anything at least along the main part of Basin Road.”

She suggested having a second crosswalk farther west on the part of the road that ends at the West Dock. “They know the road ends,” she said, “so they don’t realize traffic might still want to go further.”

Mr. Mayhew suggested flattening the inside bank on Basin Road and removing some bushes there to improve visibility going around the corner.

Harriet Poole Otteson suggested removing enough of the bank to have a grass path and not allowing cars to park in a sandy patch on the opposite side of the road. “It makes it really tight going around that corner,” she said of the parked cars, “and then you get people walking in the road.”

Walking paths along Basin and North Roads, and a turnaround where North Road meets the West Dock have also been proposed. The selectmen plan to work with property owners in the area to increase the available space for cars and pedestrians.
