Summarizes common and important mistakes that new growers will make when first starting.

A study to provide an up-to-date and accurate annual statewide economic contribution of Maine’s aquaculture industry and determine aquaculture business owner and farm demographics.

A guide on what is soft-shell clam farming, how to start your own farm, and quick overview of the financials of clam farming.

After purchasing used shellfish production equipment, it is strongly recommended to thoroughly clean and disinfect the gear prior to use to limit the risk of introducing disease or invasive species. An easy-to-use process is as follows:

In depth document created to provide the information and a framework that will enable a shellfish farmer to write a comprehensive Best Management Practices document focusing on gear/operation and maintenance, user conflicts, permitting/siting, and environmental concerns.

An ID guide to organisms commonly found in, on, and around oyster grow bags ​and other aquaculture equipment used in the Gulf of Maine and North Atlantic.

In September 2023 the ECSGA updated its 2010 Best Management Practices manual. Building on the 2010 version, this update adds a new section on the management and handling of floating gear, hundreds of embedded links, info on new gear types and a revised bibliography. ECSGA also completely revamped the tool to create your own farm-specific Best Practices document: the Best Practices Form.

This directory is intended to identify shellfish hatcheries and nurseries from along the east coast of the United States in order to serve as a tool for providing a stronger link between shellfish seed suppliers and shellfish farmers. The directory includes contact information for each business, as well as some additional information indicating the type of operation (i.e., hatchery, nursery, or research) and what products they expect to have available.

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.

If you have been around this business for a while, you’ve probably watched some of the newcomers make the same mistakes you did when you were getting started. ECSGA Executive Director Bob Rheault decided he would try to think of as many of these common pitfalls as he could to help new growers avoid making the same costly blunders. Through the years he has continued to add to the list.

The “Clam Kit” video series shares techniques developed at Downeast Institute to help municipal shellfish management programs enhance their softshell clam flats affordably and effectively. This video gives an overview of clam seed, DEI's hatchery, floating nursery trays, public stock enhancement, DMR lease or LPA, basic husbandry, overwintering, and more.

There are several ways in which birds interact with shellfish aquaculture. Birds can cause significant damage to crops through predation. Some birds fall into the category of protected resources and farmers have been variously accused of interfering with foraging, (either attracting or disturbing or both) and interfering with hunting. Birds can be attracted to aquaculture structures for roosting or foraging and their guano can impact water quality and trigger the need for growers to develop management plans under the National Shellfish Sanitation Plan.

Powerpoint on biofouling including, economic impact, general impact, common fouling organisms (macroalgae, tunicates, hydroids, boring sponge, over-set of barnacles, mussels, or oysters), controlling fouling, and methods to avoid, mitigate, or prevent the effects of biofouling.

This non-profit organization helps export Northeast food and agricultural products overseas since 1973. They provides a wide range of services to facilitate trade between local food suppliers and importers around the world including: export education, self-paced training & expert advice, customized export assistance, new market analysis, international marketing &branding, facilitate meetings with international buyers, and a cost-share funding program.

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.

Oyster aquaculture, like any agriculture operation, has inherent risks with perils beyond growers’ control. However, coastal waters present challenges for oyster farmers in the form of tropical storms and hurricanes.

Biofouling, or plants and animals that colonize oysters and/or cages, can affect profitability. This handbook reviews macroalgae, cushion moss, encrusting bryozoan, barnacles, false mussels, hooked mussels, slipper limpet, ghost anemone, sea squirts, boring sponge, red beard sponge, clam worms, mud worms, & whipworms.

This project aimed to identify a gear coating that deters and mitigates predation by oyster drills (Urosalpinx cinerea) and starfish (Asterias rubens) on aquaculture eastern oysters. Identifying potential strategies to mitigate starfish and oyster drill snail predation on eastern oysters could increase oyster survival, which would increase yield and revenue.
