The report provides information on commercially relevant aspects of oyster production gear associated with each equipment type employed including, BST™ Crosshatch, BST™ Longline, OysterGro, Rack and Bag, & Seapa™. They tracked oyster survival, growth by season, shell morphology, worm presence, and cost estimates.

This web-based, report-centric tool provides coastal and ocean planners with a high-level analysis for their custom-drawn area of interest. It provides summary statistics and infographics for six main topics: general information, energy and minerals, natural resources and conservation, oceanographic and biophysical, transportation and infrastructure, and economics and commerce.

DMR resources for growers including approved hatcheries, biosecurity, shellfish sanitation, harvest and reporting, and forms.

The aim of this open access book is to review and analyze the goods and services of bivalve shellfish.

This workbook is designed to help municipal shellfish committees apply for limited purpose aquaculture permits (LPA). These permits are required for various conservation projects, particularly focused on reseeding or revitalizing wild spawning. It was created collaboratively, with members of the DMR, various municipal shellfish committees, and others working to provide materials and input on the final product.

A global fish and shellfish health lab, we offer you top-quality diagnostics, import/export inspections, and veterinary solutions from consultation to custom vaccines.

This report addresses biofouling management in relation to marine aquaculture industry operations, equipment and infrastructure. It covers shellfish, finfish and seaweed operations in estuaries and seawater. It does not address freshwater aquaculture activities.

UC Davis Aquaculture visits Dr. Julieta Martinelli at the University of Washington, Seattle, to learn about the shell-boring marine worm polychaete, otherwise known as blister worms (Polydora websteri), and the treatments to control them in oyster shellfish aquaculture farms.

All wild shellfish stock or seed used for cultivation or grow-out must originate from within the same Limited Purpose Aquaculture (LPA) license Health Zone as the LPA license site. A permit is required from DMR if the stock or seed originates from outside the Health Zone.

Aquaculture of softshell clams (Mya arenaria), also called “steamer clams”, has grown steadily and is becoming a significant industry in New England. Examined in this fact sheet are specific aspects of softshell clam production during the Hatchery Phase and a description of variations in management practices at three shellfish facilities: two in Massachusetts and one in Maine.

A variety of tenacious myths critical of marine aquaculture practiced in the United States have persisted for decades to be presented as facts to the public and Congress. The reality is U.S. fish and shellfish farmers culture aquatic animals and plants within a very complicated and expensive legal, regulatory, husbandry, and science-driven environment. We believe critics are unfamiliar with this environment or have erroneously assumed marine aquaculture-related environmental damage reported in other countries occurs in the United States.
