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.

Provides a comprehensive resource to help managers at the local and state level sustain Maine’s valuable shellfish resources. Includes information on the history and biology of the soft-shell clam, northern quahog, American and European oysters, and blue mussels. There are sections on state resources to address water quality issues and predatory species and tools that municipalities can use to preserve or increase their intertidal shellfish resources.

Reviews the types of harmful phytoplankton that produce biotoxins such as Alexandrium, which causes paralytic shellfish poisoning; Pseudo-nitzschia, which causes amnesic shellfish poisoning; and Dinophysis, which causes diarrhetic shellfish poisoning.

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.

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 goal of these new requirements is to control the safety of molluscan shellfish for human consumption by preventing unnecessary growth of bacterial pathogens resulting from improper or ineffective cooling or from time to temperature abuse.

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.

Guidance document for industry that identifies areas DMR has deemed a high biotoxin risk and specific management criteria for safe harvest.

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

Presentation on oyster pathogens and diseases such as MSX, SSO, dermo, and Vibrio, testing protocols, long-term management, oyster predators & pests, the difference bewteen infection and disease, disese prevention, biosecurity, risk evaluation, pathogen surveillance, and zonation.

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.

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.

This book was designed with Certified Shellfish Dealers in mind and gives detailed information about HACCP Plans (Hazard Analysis Critical Control Point), monitoring of Daily Sanitation practices, SSOP (Sanitation Standard Operating Procedures), Tags, Tagging & Transportation of Shellstock, Wet Storage Standard Operating Procedure, and more.
