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

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.

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.

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.

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.

An overview of oyster production techniques including nursery and husbandry, common gear used, and oyster biology.

This report is based on the research priorities survey conducted in June 2019 of Maine’s aquaculture community and is compared with surveys from 2012 and 2016 to look at trends. There have been some changes in the prioritization of needs since 2016, but many of the same research, development, and education (R&D&E) needs persist and remain unaddressed. As expected, there are different R&D&E priorities for different aquaculture sectors.

Provides a summary of direct and indirect environmental factors that may affect your site selection for your marine aquaculture business.

Good husbandry is critical to success and this gives a general overview of its importance.

A study designed to measure the effect of stocking density and bag mesh size on the growth of pre-commercial oysters (60 mm) deployed at three sites in northeastern New Brunswick.

Intended to help prospective farmers to identify, record, monitor, and manage production hazards, and ultimately minimize production-related risk. Discusses types of risk in aquaculture, record keeping, environmental conditions, biofouling organisms, predators, diseases, parasites, invasive species, and operational procedures.

Use this to create your own farm-specific Best Management Practices (BMP) document use this template, a Microsoft Excel file in macro format.

Intended for a novice farmer to give a overview of oyster farming topics such as oyster biology, site selection, rearing methods, spat supply, and production plans.
