Edgartown selectmen voted Monday to renew the aquaculture license of Francis (Sandy) Fisher, but with the proviso that his lease will not be renewed if he receives one more citation for violating the town’s shellfishing regulations.

In a letter to the board of selectmen, shellfish warden and biologist Paul Bagnall said Mr. Fisher has been cited numerous times for violations relating to his oyster farm.

“Francis and his father have been cited for various infractions over the years that primarily concern keeping gear and activities confined to their leased area,” Mr. Bagnall said. “This September Mr. Fisher was cited by the Massachusetts Department of Marine Fisheries for non-compliance with Vibrio harvest protocol.”

Vibrio is a bacteria that has caused several closures of Katama Bay oyster farms over the past several years. It can cause severe stomach distress, and in rare cases, death.

“We need to have better compliance with aquaculture rules and regulations,” Mr. Bagnall told selectmen at Monday’s meeting.

On the recommendation of its shellfish committee, the board voted unanimously to renew the lease, but with a stern admonition.

“This is your last warning,” chairman Margaret Serpa said.

Selectmen, also on the recommendation of the shellfish committee, voted to open Edgartown Great Pond to commercial oyster fishing from April 3 to April 28. Commercial permit holders can take up to two 10 gallon baskets of oysters per day, Monday through Friday.

Oyster harvesting will close in Sengekontacket Pond on March 31.

Selectmen voted unanimously to allow the highway department to begin clearing land along Meshacket Road for construction of new bike lanes. The work will involve removing 100 to 125 trees, mostly pitch pine of various sizes, from within the town-owned land on either side of the road according to highway superintendent Stuart Fuller.

Selectmen awarded a contract for landscaping work at the Edgartown fire station to TDR Landscape and Irrigation, based on a bid of $94,820. The landscape plan calls for new brick sidewalks, fences, and plantings.
