Federal Legislation Proposed: Ocean Acidification

Shared on behalf of Tessa Getchis, Extension Educator of Connecticut Sea Grant.

EYES ON OCEAN ACIDIFICATION: Two House bills were introduced this week to promote research on ocean acidification, an issue biologists and the seafood industry are concerned about. Maine Democrat Chellie Pingree introduced a bill to require the NOAA study the impact of acidification on coastal communities; Washington state Democrat Derek Kilmer and Republican Jaime Herrera Beutler also introduced legislation that would direct federal agencies to create competitions to promote research and potentially open new ways of managing acidification.

Ocean acidification could be a real threat to the fisheries that are the lifeblood of coastal communities,” Pingree said. “The truth is, we don’t fully understand how it would impact a vital industry like the lobster fishery and what the effect would be on Maine. We know what’s causing ocean acidification but now we need to better understand how hard it is going to hit coastal economies.’ More on Pingree’s bill is here: https://pingree.house.gov/media-center/press-releases/pingree-introduces-bill-study-impact-ocean-acidification-coastal Kilmer and Herrera Beutler’s bill is here: http://1.usa.gov/1mbY1DF

RI clams: some are Notata and some are not

Question: What’s up with the markings on some RI clams?

The normal “white” quahog that we usually see in the bay are referred to (in science speak) as the “alba” variety. Those with a reddish-brown pattern on their shell are referred to as “notata” variety. Both are normal, native clams that can be found naturally in RI waters. The only difference is that one has a different shell color than the other. It is a simple, natural single locus variation in the genetics of the clam.

Normally, the natural population of wild “notata” clams (the ones with the reddish-brown zig-zag pattern on their shell) occur at about 1-2% in the wild. When we breed clams for enhancement, we increase the percentage of those clams by simply crossing notata clams with notata clams. In the wild this does not happen often, for the density of wild notata’s is so low. When we do it in the hatchery, the number of notata clams is about 75% of the total. So when we raise and release clams for enhancement, we can track our clams by counting how many notatas there are in the catch. Anything over 2% means that we are having success with our plantings. For example, the Shellfishermen’s Association planted about 500,000 notata clams in Green’s River (Potowomut) in (about) 2004. When the area opened for fishing three years later, the catch was about 25-30% notata’s, suggesting that our enhancement program was working well.

A large number of the clams that were caught in Galilee during the July 23rd Clamming Class were notatas and they were harvested from an area where the Rhode Island Shellfishermen’s Association have been planting enhancement clams for the past three or four years. So, again, the enhancement program is working. In this case, the fishermen are planting the nursery reared clams there specifically to help out the recreational harvest for the tourists and state residents.

CRC, Sea Grant leading effort to develop Rhode Island Shellfish Management Plan

NARRAGANSETT, R.I. – July 16, 2013 — The University of Rhode Island is continuing to play a leadership role in helping the state plan for the future of its shellfishing resources through the Rhode Island Shellfish Management Plan. The effort is well underway, with the URI Coastal Resources Center (CRC) and Rhode Island Sea Grant College Program at the URI Graduate School of Oceanography serving as chief facilitators.

It’s a milestone project for the Ocean State, which claims the quahog as its official shellfish. In 2013, CRC and Sea Grant brought together state agencies, researchers from URI and Roger Williams University, and myriad stakeholders — members of Rhode Island’s traditional wild harvest industry, representatives from the growing aquaculture field, the nonprofit community concerned with restoration of shellfish in the Bay and coastal ponds, and the recreational clamming community — to collaborate on the plan.

Some of the ideas that have emerged so far call for the creation of guiding policies that: 1) build understanding of the economic, environmental and cultural values of the local resources and industries; 2) propose alternative management strategies and new mechanisms for implementation; and 3) promote science-based shellfish management decisions by increasing science activities.

The project garners interest not only for its potential to improve how shellfish are grown and harvested in state waters, but also for the support it may provide to the shellfish industry and the awareness it may raise about the social and cultural values that Rhode Islanders connect to the resource.

These concerns were front and center when the project launched late in 2012, and CRC and Sea Grant are working with the Rhode Island Department of Environmental Management, the Rhode Island Coastal Resources Management Council, and state agencies with regulatory responsibilities for overseeing shellfish management in the state, on the initial phase of the plan. Joining in these concerns are key supporters — the Rhode Island Foundation, the Prospect Hill Foundation, the Sharp Family Foundation/Henry and Peggy Sharpe, and the URI Coastal Institute.

Getting the public involved in the project has been a key initiative, and spring 2013 saw URI providing the public with plenty of opportunities to engage in the planning process, from stakeholder meetings to workshop sessions at which attendees could identify critical resource areas on maps. For the summer season, citizens have the chance to sign up for guided clam-digging tours. Additional events are slated for the fall.

Also in the fall, a new phase of development of the shellfish management plan will get underway, as the draft plan chapters are created and provided to the public for review and comment. But even once the plan is developed, the work is far from over. In fact, implementation — the carrying out of the plan policies by the state agencies in collaboration with stakeholder groups — will require continued improvement and enhancement of the policies as new information and data become available.
