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:

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.

This video gives a first-hand account of running a mussel farm by Bangs Island Mussels including on the water gear and husbandry and well as shore-side processing. Some highlights are seeding, socking, hauling and stripping machine, de-clumper, size grader, debyssing machine, automatic bagger/weigher/conveyor, and more.

Webinar about research on scallop aquaculture production and economics including comparisons of nursery and growout gear: lantern nets, pearl nets, ear hanging, pocket nets, rigid trays, and adhesives; tissue sampling and testing for biotoxins such as saxitoxin and domoic acid; evaluation of fouling communities; surveys of producers to understand economic inputs and outputs such as capital, labor, and yield; environmental data matched with growth data to better understand good scallop-farming sites.

When submitting a LPA application one of the details that can make or break your approval is your mooring system. Understanding and installing moorings that work for the load that aquaculture gear generates is crucial and creating an accurate and readable mooring system design in your application is key for your approval.

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.

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.

In depth review of sea scallop biology, spat collection, nursery, grow out, gear, husbandry, site selection economic considerations and biotoxins/public health.

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

Overview of how Pemaquid Mussel Farms reached their development goal of a 5 fold increase in production within 10 years to $15 million annually using new technology and business planning.

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

Reviews tide–flipped bags or baskets ability to produce a more attractive and commercially valuable Eastern oyster for the half–shell market. Found that flip-bag oysters grow slower but had a wider fan, deeper cup, heavier shell, yielded more meat, were less fouled, and required less labor to maintain.

Presentation on what was learned from Japan, the world leaders in scallop aquaculture, including lantern nets, spat bags, grading, washing, and recipes.

As part of an ongoing and productive relationship, a delegation from Maine visited the gear supplier Mutsu Kaden Tokki Co., Ltd. located in Aomori Prefecture, Japan. This video reviews the gear needed for the Japanese scallop aquaculture industry technique called 'ear-hanging'.

This video is narrated by Dana Morse and reviews how to collect sea scallop spat and grow your seed in bottom cages.

A study compared how oysters grew in floating cages versus bottom cages that determined that generally oysters grew faster and survival and condition index were higher in floating gear.

An in-depth guide on kelp farming including how to set up a farm, the application process, nursery set-up, maintaining cultures, and farm site operations.
