Shellfish Hatchery
EAST HAMPTON TOWN SHELLFISH HATCHERY The 2015 Crew, left to right: Kate, Pete, Carissa, Shelby, and Barley 2015 ANNUAL REPORT AND 2016 OPERATING PLAN Prepared by Kate Rossi-Snook Edited by Barley Dunne East Hampton Town Shellfish Hatchery The skiff loaded for seeding in Lake Montauk Annual Report of Operations Mission Statement With a hatchery on Fort Pond Bay, a nursery on Three Mile Harbor, and a floating raft field growout system in Napeague Harbor, the East Hampton Town Shellfish Hatchery produces large quantities of oyster (Crassostrea virginica), clam (Mercenaria mercenaria), and bay scallop (Argopecten irradians) seed to enhance valuable shellfish stocks in local waterways. Shellfish are available for harvest by all permitted town residents. Cooperative research and experimentation concerning shellfish culture, the subsequent success of seed in the wild, and the status of the resource is undertaken and reported upon regularly, often funded and validated by scientific research grants. Educational opportunities afforded by the work include school group and open house tours and educational displays at community functions. Annual reporting includes production statistics and values, seed dissemination information, results of research initiatives, a summary of outreach efforts, the status of current and developing infrastructure, and a plan for the following year’s operations. 2015 Full-time Staff Part-time and Contractual Volunteers John “Barley” Dunne – Director Carissa Maurin – Environmental Aide Romy Macari Kate Rossi-Snook – Hatchery Manager Shelby Joyce – Environmental Aide (summer) Christopher Fox-Strauss Pete Topping – Algae Culturist Adam Younes – Environmental Aide (fall) Jeremy Gould – Maintenance Mechanic Carissa and Pete unloading OysterGros Special Thanks to: Barnaby Friedman for producing our annual seeding maps. -

The intelligence of octopuses has long been noted, and to some extent studied. But in recent years, play, and problem-solving skills has both added to and elaborated the list of their remarkable attributes. Personality is hard to define, but one can begin to describe it as a unique pattern of individual behavior that remains consistent over time and in a variety of circumstances. It will be hard to say for sure whether octopuses possess consciousness in some simple form.

Embryonic and Larval Development of Ensis Arcuatus (Jeffreys, 1865) (Bivalvia: Pharidae)

This work is the first study to research the embryology and larval development of this species of razor clam, using light and scanning electron microscopy. A new method, consisting of changing water levels using tide simulations with brief Downloaded from https://academic.oup.com/mollus/article/74/2/103/1161011 by guest on 23 September 2021 dry periods, was developed to induce spawning in this species. The blastula was the first motile stage and in the gastrula stage the vitelline coat was lost. The shell field appeared in the late gastrula. The trocho- phore developed by about 19 h post-fertilization (hpf) (198C). At 30 hpf the D-shaped larva showed a developed digestive system consisting of a mouth, a foregut, a digestive gland followed by an intestine and an anus. Larvae spontaneously settled after 20 days at a length of 378 mm.

Scallop SAFE 2021

Under the FMP, the report is prepared by the Alaska Department of Fish and Game (ADF&G) with input from the National Marine Fisheries Service (NMFS) and the Council’s scallop plan team (SPT). The SAFE summarizes current biological and economic status of the fisheries, guideline harvest levels, and support for different management decisions or changes in harvest strategies. In the absence of annual estimates of stock size, optimum yield (OY) and maximum sustainable yield (MSY) remain at fixed values, as per the FMP. Following recommendations from the SSC, an expanded executive summary with updated information will be produced as the SAFE report every other year, beginning in 2021. The Scallop Plan Team met on February 17th, 2021 to update the scallop SAFE executive summary with recent fishery independent survey information and fishery performance data. The Plan Team review was based on presentations by staff from the ADF&G, Council, and NMFS and included opportunities for public comment and input. -
Predators in Action: Rapa Whelks Vs. Hard Clams

It Harding. is very likely that the Chesapeake Bay population be- gan with the introduction of baby snails from the Black Sea into the waters of the lower Chesapeake Bay in ships’ ballast water. Rapa whelks eat bivalve molluscs. They are generalist predators; that is, they do not require a particular kind of bivalve. They will eat whatever bivalves are avail- able to them. In the lower Chesapeake Bay the poten- tial menu for rapa whelks includes hard clams (Mercenaria mercenaria, Figure 2), mussels (Mytilus Figure 2: Two adult hard clams. These animals are and Geukensia sp.), and oysters (Crassostrea virginica), approximately 80 mm long. ©2003. J. Harding. as well as others.
