Measuring Atlantic Bluefin Tuna with a Drone
June 10, 2020 — This novel use of drones is a promising way to remotely monitor these hard-to-see fish
Researchers have used an unmanned aerial system (or drone) to gather data on schooling juvenile Atlantic bluefin tuna in the Gulf of Maine.
This pilot study tested whether a drone could keep up with the tuna while also taking photographs that captured physical details of this fast-moving fish. The drone was equipped with a high-resolution digital still image camera. Results show that drones can capture images of both individual fish and schools. They may be a useful tool for remotely monitoring behavior and body conditions of the elusive fish.
Individual fish lengths and widths, and the distance between fish near the sea surface, were measured to less than a centimeter of precision. We used an APH-22, a battery-powered, six-rotor drone. The pilot study was conducted in the Atlantic bluefin tuna’s foraging grounds northeast of Cape Cod in the southern Gulf of Maine.
“Multi-rotor unmanned aerial systems won’t replace shipboard surveys or the reliance on manned aircraft to cover a large area,” said Mike Jech, an acoustics researcher at the Northeast Fisheries Science Center in Woods Hole, Massachusetts and lead author of the study. “They have a limited flight range due to battery power and can only collect data in bursts. Despite some limitations, they will be invaluable for collecting remote high-resolution images that can provide data at the accuracy and precision needed by managers for growth and ecosystem models of Atlantic bluefin tuna.”
Small boats and female workers hardest hit by Covid-19 fisheries impact
June 10, 2020 — Small fishing boats, fish markets and female workers are among the categories worst affected by the economic impact of the coronavirus crisis on the world’s fisheries, research has found.
Supply chains around the world have been disrupted by the Covid-19 pandemic, and artisanal fishing – small boats – has borne the brunt, according to the annual report on fisheries by the UN Food and Agriculture Organisation (FAO). While industrial fishing fell only by about 6.5% in April, a large proportion of small vessels around the world have been in effect confined to port, and their markets are uncertain.
In parts of the Mediterranean and the Black Sea, more than 90% of small-scale fishing fleets have had to stop fishing owing to a lack of markets and falling prices.
The closure of restaurants, hotels and catering has cut off markets for small boats and led to falling prices, and the resulting disruption has led to an increase in waste, according to an appendix to the annual report, published on Monday for World Oceans Day.
STUDY: MATURE OYSTER REEFS COULD BOOST BLUE CRAB NUMBERS BY 80%
June 9, 2020 — Restoring oyster reefs is a priority on the Chesapeake Bay, as we know healthy oyster populations can buoy Bay-wide clean water efforts. But the National Oceanic and Atmospheric Administration (NOAA) wanted to know just how much restored reefs can help, and how that could translate to the Bay region’s economy.
So NOAA Fisheries’ Office of Habitat Conservation used a high-tech model to predict long-term benefits of restored oyster reefs in the Choptank River system. Spoiler alert: the predicted benefits would be remarkable for both the ecology and the crab industry.
Together with six partner institutions, NOAA published a technical memorandum that looks at oyster reefs in Harris Creek, the Little Choptank River, and the Tred Avon River, all parts of the Choptank system that have been targeted with large-scale oyster restoration under the Chesapeake Bay Watershed Agreement. These reefs are considered “young” today (Harris Creek’s oyster sanctuary was just completed in 2015, and the other two are still underway), but the research model also looked at what may happen when the reefs are “mature,” roughly 15 years after restoration.

Science Center for Marine Fisheries Funds Over $173,000 in New Research
June 8, 2020 — The following was released by the Science Center for Marine Fisheries:
At its spring meeting, the Science Center for Marine Fisheries (SCEMFIS) approved 6 new research projects and awarded $173,547 in funding. Coming as the fishing industry continues to deal with the fallout of the COVID-19 crisis, the projects funded by the Center deal with some of the most economically important issues for the future of the industry.
These projects include efforts to study how offshore windfarms impact marine life; how to improve stock assessments for one of the largest fisheries in the country; and how to better use shellfish byproducts as commercial products. All projects were approved by the SCEMFIS Industry Advisory Board (IAB), which is composed of Center members in the finfish and shellfish industries. The SCEMFIS IAB encourages companies with an interest in promoting sustainability in the industry to consider joining.
SCEMFIS is a member of the National Science Foundation’s Industry-University Cooperative Research Centers (IUCRC) program, a federal initiative to bring together academic researchers and industry members to fund projects improving our understanding of economically important issues.
The following projects were approved at the spring meeting:
- Wind energy development team supporting fisheries – As offshore wind farms continue to expand, they will increasingly interact with critical fish species and ocean habitats. Understanding these interactions and assessing their impacts is essential to future coexistence between offshore wind and fisheries. The project, by Dr. Eric Powell (University of Southern Mississippi), will assemble a wind energy team with diverse areas of expertise to advise SCEMFIS members on potential environmental impacts for offshore development. ($20,200 in funding)
- Could federal wind farms influence continental shelf oceanography and alter shellfish larval dispersal? A literature review – With over 1.7 million acres of federal waters under lease for wind energy development, new wind energy structures have a significant potential to interfere with ocean conditions, including in critical areas such as how shellfish larvae are dispersed. The project, by Dr. Daphne Munroe of Rutgers University, will review existing literature to determine how wind energy development has affected different oceanographic conditions, and prepare a report on these findings for the public. ($17,791 in funding)
- Developing process and procedures for the refinement of surfclam and ocean quahog shells into calcium carbonate – Calcium carbonate is an important shellfish byproduct, used in animal feed, biomedical products, and other applications. Because of their chemical composition, quahog and surfclam shells are an especially good source of calcium carbonate compared to other shellfish, such as oysters. The project, by Dr. Alireza Abbaspourrad (Cornell University), will develop a process to tailor the carbonate byproduct to its other uses. ($50,000 in funding)
- Evaluation the impact of plus group definition on the Atlantic and Gulf Menhaden stock assessments –Atlantic and Gulf menhaden are, by volume, two of the largest fisheries in the U.S. But one major source of uncertainty in its stock assessments are the number of older fish in the population. These fish are inadequately assessed by current surveys. The project, from Drs. Genevieve Nesslage (University of Maryland), Robert Leaf (University of Southern Mississippi), and Amy Schuler (National Marine Fisheries Service), will create a new model to simulate how different levels of these older fish would impact the results and accuracy of the menhaden stock assessments. ($53,414 in funding)
- Atlantic menhaden stock review – The project, by Dr. Steve Cadrin (University of Massachusetts Dartmouth), will provide a technical review of the Atlantic States Marine Fisheries Commission’s stock assessment for Atlantic menhaden, as well as provide a new analysis of estimated rates of menhaden natural mortality, and the percentage of the population that is allocated for ecosystem needs. ($3,520 in funding)
- Retention of Expertise in SS-III and evaluation of past and predictive modeling of future stock status – Stock assessments for ocean quahog and surfclams rely on a specific modeling tool, the Stock Synthesis V3. The project, from Drs. Eric Powell (University of Southern Mississippi) and Roger Mann (Virginia Institute of Marine Science) will recruit a Ph.D. student to train to use the model, with the goal of maintaining scientific expertise in using and understanding it. ($28,622 in funding)
As NOAA predicts larger than average Gulf dead zone, study reveals billions in damage to fish stocks
June 5, 2020 — NOAA scientists announced on 3 June that the forecast for the Gulf of Mexico hypoxic area, more commonly referred to as the “dead zone,” will be larger than average in 2020.
The current forecast of the dead zone – an area of low to no oxygen that can kill fish and other marine life – predicts an area of roughly 6,700 square miles, which is larger than the recent average measured size of the dead zone of 5,387 square miles. For comparison, 6,700 square miles is roughly the size of the U.S. states of Rhode Island and Connecticut combined.
Lobsters and Sea Scallops Moving Out of Southern N.E.
June 5, 2020 — Researchers have projected significant changes in the habitat of commercially important American lobster and sea scallops along the Northeast continental shelf. They used a suite of models to estimate how species will react as waters warm. The researchers suggest that American lobster will move further offshore and sea scallops will shift to the north in the coming decades.
The study’s findings were published recently in Diversity and Distributions. They pose fishery management challenges as the changes can move stocks into and out of fixed management areas. Habitats within current management areas will also experience changes — some will show species increases, others decreases, and others will experience no change.
“Changes in stock distribution affect where fish and shellfish can be caught and who has access to them over time,” said Vincent Saba, a fishery biologist in the Ecosystems Dynamics and Assessment Branch at the Northeast Fisheries Science Center and a co-author of the study. “American lobster and sea scallop are two of the most economically valuable single-species fisheries in the entire United States. They are also important to the economic and cultural well-being of coastal communities in the Northeast. Any changes to their distribution and abundance will have major impacts.”
Saba and colleagues used a group of species distribution models and a high-resolution global climate model. They projected the possible impact of climate change on suitable habitat for the two species in the large Northeast continental shelf marine ecosystem. This ecosystem includes waters of the Gulf of Maine, Georges Bank, the Mid-Atlantic Bight, and southern New England.
Researchers predict warming Atlantic will push lobsters offshore, scallops northward
June 4, 2020 — East Coast sea scallop stocks will likely follow lobsters in shifting away from rich Mid-Atlantic and southern New England grounds in the coming decades as a consequence of warming ocean waters, according to a new study that projects the impact of climate change on the two richest Atlantic fisheries.
Researchers used species distribution models and a high-resolution global climate model to picture the possible impact of climate change on habitat for lobsters and scallops in the Northeast continental shelf ecosystem, ranging from the New York Bight north to southern New England, Georges Bank and the Gulf of Maine.
The researchers note that the latest benchmark assessment of the lobster stock, cited by the Atlantic States Marine Fisheries Commission in 2015, showed the stock in the southern Mid-Atlantic range was already severely depleted due to several environmental factors including recruitment failure and shell disease related to warmer waters.
