Shellfish Economy Depends on Research Reserve Data

Data from the National Estuarine Research Reserves helps the US shellfish industry increase commercial yields. Lynker’s staff at NOAA’s Office for Coastal Management help tell the story for National Seafood Month.

Multimillion-Dollar Shellfish Economy Depends on Research Reserve Data

By monitoring oxygen, eelgrass health, and other marsh variables, the data system supports shellfish habitat and commercial yields.
U.S. estuaries are the lifeblood of commercial shellfishing. Total fish catch in estuaries contributes $4.3 billion annually to the national economy, and estuaries are nurseries to more than 75 percent of all the fish and shellfish harvested. Data from the National Estuarine Research Reserve System’s environmental monitoring program keeps shellfish businesses informed about conditions and supports product safety. Examples are provided below:

• The West Coast reserves—California’s San Francisco Bay and Elkhorn Slough, Oregon’s South Slough, and Washington State’s Padilla Bay—provide the region’s $270 million annual commercial shellfish industry with critical data about marsh health, including oxygen and nitrogen levels, eelgrass health, turbidity, restoration, and other marsh variables.

• In Massachusetts, the Waquoit Bay Reserve’s water-temperature data are routinely used by the state’s shellfish aquaculture industry, an economic powerhouse that in 2013 generated more than $25 million in profits and paid out nearly $12 million in wages.

• The Apalachicola (Florida), ACE Basin (South Carolina), and North Inlet-Winyah Bay (South Carolina) reserves collect rainfall, salinity, and temperature data critical to the commercial blue crab industry, which in Florida alone carried a dockside value of over $12 million in 2015.

• In North Carolina, the commercial oyster harvests garner $4.5 million in annual profits. Harmful bacteria have caused repeated shellfish farm closures, so the North Carolina Reserve and University of North Carolina are developing a tool to help shellfish aquaculture firms make more-informed siting decisions.

• In Alaska, the Kachemak Bay Reserve supplies real-time temperature, oxygen, acidification, and toxin-related data used by commercial oyster farms and state officials. Alaska’s seafood industry employs more people than any other private industry in the state, and fishermen in this North Pacific region made $238 million in 2014 from crab alone.

• In South Carolina, data from the ACE Basin Reserve aids the state’s shrimp industry—which in 2015 netted more than two million pounds with a dockside value of over $8 million—by predicting areas of shrimp abundance and sending out alerts when black-gill disease is found. (2017)

Cold-Stun Alert Helps Save Spotted Seatrout in VA and SC

The National Estuarine Research Reserves in Virginia and SouthCarolina have a cold-stun alert that aids fisheries to temperature drops and potential die-offs. Check out the story written by Lynker staff at NOAA’s Office of Coastal Management.

Cold-Stun Alert Aids Fishery Managers and Seatrout Stocks

The alerts’ real-time monitoring data comes from three research reserves in Virginia and South Carolina.

Virginia’s Chesapeake Bay National Estuarine Research Reserve is piloting a cold stun alert system that identifies when sudden drops in water temperature could cause die-offs of Spotted Seatrout and other species along Virginia’s Bay areas and the South Carolina coast. It gives commercial and recreational fishermen the chance to take actions that can preserve existing stocks. Spotted sea trout (Cynoscion nebulosus) are popular catches for commercial and recreational fishermen trolling the Chesapeake Bay, Southeast coast, and Gulf of Mexico.

The alerts use real-time monitoring data from the Virginia research reserve as well as South Carolina’s ACE Basin and North Inlet-Winyah Bay research reserves. The system also logs how long each temperature drop lasts. “Winter kills” are a serious threat to local and regional Spotted Seatrout. The cold-stun alert can help fishery managers act to save fish populations by temporarily cutting their catch quotas or asking recreational fishermen to “catch and release” for a limited time. For example, a 2018 winter kill along Virginia’s coast motivated North Carolina’s Division of Marine Fisheries to enact an emergency season closure through June 15, which allowed surviving seatrout to spawn in springtime.

Spotted Seatrout is an important cash crop for commercial fisheries. In 2017, North Carolina’s Division of Marine Fisheries reported commercial landings of nearly 300,000 pounds of this species. The Virginia research reserve hopes to expand the alert system to the Gulf of Mexico and other areas along the Southeast and Gulf of Mexico coasts. (2018)

 

Lynker, Pacific Islands Fisheries Group, and Local Fishers Collaborate

Lynker and the Pacific Islands Fisheries Group (PIFG), a Hawaii-based research cooperative, have been out on the water this fall, sampling in 75 fishing locations to determine abundance and health of Hawaii’s “Deep 7” bottomfish, including opakapaka (pink snapper), onaga (longtail snapper), ehu (squirrelfish snapper), kalekale (Von Siebold’s snapper), gindai (Brigham’s snapper), lehi (silverjaw snapper), and hapuʻupuʻu (Seale’s grouper).
These fish species are jointly managed by state and federal authorities, and our work, funded by NOAA Fisheries, will help scientists, policy-makers, and the local community better ensure the sustainability of these important stocks (currently not overfished) now and into the future.
The research fishing portion of the survey is now 44% complete, with overall survey completion at 66%.
A huge shout-out to the local fishing captains and observers, who spend days on the water, often in less than ideal conditions, collecting the samples around the islands of Kauai, Oahu, Maui, and the Big Island, in making this survey a success.

Scavenger Hunt in Rota and Saipan to Gain LIDAR Data

Lynker employees Jamie Carter and Ross Winans recently surveyed sites in the Commonwealth of the Northern Marianas Islands (CNMI) supporting @NOAA Digital Coast’s LIDAR validation work. In addition, they were able to acquire NGS-compliant data at several of the benchmarks that NGS needs for the Mariana Terrestrial Reference Frame of 2022 (MATRF2022) – all while lugging around over 350 pounds of equipment!

They travelled to Rota, Saipan, and Tinian, hiking approximately 25 sites per island. Our work is part of the NOAA Office for Coastal Management’s Digital Coast and critically useful for restoring infrastructure and mitigating hazards.

Lidar data is commonly used and accessed for the rest of the U.S., but none existed for the Commonwealth of the Northern Marianas Islands (CNMI). Local managers can now use this data to create inundation and storm surge models, shoreline maps, tsunami models and zones, and habitat maps. Additionally, this data will be used to create emergency response plans and assist many coastal resource managers, scientists, and emergency response personnel with disaster preparedness. 

Local and federal agencies had a large stake in this project, while community involvement and support was crucial throughout. NOAA, FEMA, and USDA are all heavily invested in LIDAR data, and this project enhanced their collaboration on data collection and processing. Additionally, we worked with NGS to perform quality assurance on all of the data and be compliant with their standards.

Trekking through these islands was like a large scavenger hunt to find each site, especially the ones with challenging access points and location descriptions – find the corner of the fence post (that no longer exists) and your mark to find the site will be there (but may be buried).
