|NOAA economist to be SMAST Visiting Scholar
John Walden, an economist with NOAA's Northeast Fisheries Science Center (NEFSC) in Woods Hole, has been appointed to the Social Sciences Visiting Scholar position at SMAST. He is replacing Min-Yang Lee, who has returned full-time to his duties in Woods Hole. John has been on staff with the NEFSC since 1987.
For the past 15 years, John’s research has focused on measuring technical efficiency, capacity and productivity in commercial fisheries. During that time he has built an internationally recognized research program in this area. He has developed research collaborations with faculty at a number of universities, as well as with the USDA Economic Research Service and the Environmental Protection Agency.
This summer, John organized fishery sessions at both the North American Productivity Workshop, and the Asia-Pacific Productivity Conference. Additionally, he led the national effort by NMFS to measure capacity in commercial fisheries in response to a request from Congress, and more recently developed productivity metrics which were applied to U.S. catch share fisheries.
John will be co-teaching a class with Prof. Dan Georgianna in the spring semester. He also plans to develop a fully on-line course, offered through SMAST, to be centered on fisheries economics for policy decisions.

|Awards to support gear design/eddy research
SMAST Professor Pingguo He [above in photo

." The project will design and test trawling gear innovations to reduce seabed impact for the New England groundfish fishery, while significantly reducing the catch of the so-called “choke” species of flounder: yellowtail, winter and windowpane. Similar technology is successfully used in the North Pacific for Alaskan pollock and in Norway for Atlantic cod. The project is a collaborative initiative involving university and state scientists and contributors from the gear technology and fishing industries.
In a separate award, UMass Dartmouth Professor Amit Tandon [below in photo
] (Mech. Eng./SMAST) has received $324K from the National Science Foundation (NSF) for his part in collaborative research on the "Role of Mixed Layer Eddies on Phytoplankton Productivity in Seasonally Variable Regime
s." The total award is for $1.1 million over four years, with the remainder supporting the research of collaborator Dr. Amala Mahadevan of the Woods Hole Oceanographic Institution. The investigators will contribute to outreach efforts, including teacher training and ocean literacy workshops through the Ocean Academy at the Ocean Explorium in New Bedford.

|Rothschild to address Hjort Symposium
SMAST Prof. Emeritus Brian Rothschild has been invited to deliver the summary address at the Johan Hjort Symposium on Recruitment Dynamics and Stock Variability
next week in Bergen, Norway.
Hjort is widely considered to be the father of fisheries science. The occasion for the symposium is the 100th anniversary of the publication of Hjort’s seminal book, Fluctuations in the Great Fisheries of Northern Europe
According to the symposium organizers, “The importance of [Hjort’s] volume cannot be overstated, particularly Hjort’s new conceptual ideas about the formation of strong year classes based on age determination from fish scales.”
Dr. Rothschild is Professor Emeritus and former Dean of the School for Marine Science and Technology. He has edited five books and is the author of 100+ research papers.
Dr. Rothschild has worked in several capacities for the National Oceanic and Atmospheric Administration and has consulted for the United Nations and several national governments on various aspects of oceanography and fishery management. He has served on numerous national and international committees and working groups, and has led international scientific programs.
Dr. Rothschild is currently President and CEO of the Center for Sustainable Fisheries (CSF), a science-based, non-profit organization “devoted to the conservation of our fisheries resources and the economic development of our fishing communities.”[Reposted from October 3, 2014]
|Eddy wins "Best Student Paper" at AFS
PhD student Corey Eddy (Biol./SMAST) won the “Best Student Paper Presentation” award at the American Fisheries Society annual meeting last month in Quebec City for “Capture-Related Mortality and Post-Release Survival of Pelagic Sharks Interacting with Tuna Purse Seines in the Eastern Pacific Ocean.” Corey’s advisor, Prof. Diego Bernal, was co-author of the paper.
At the same meeting, UMass Dartmouth scientists and students authored or co-authored some three dozen oral and poster presentations. In addition, SMAST scientists organized and/or moderated technical sessions on Fishing Gear Selectivity and Selective Fishing; Marine Mammal and Fisheries Interactions; Fishing down the Food Web; and Modeling and Statistics.
The Society’s 144th annual meeting was sponsored by Fisheries and Oceans Canada, and the Northeastern Division, the Atlantic International Chapter, and the Canadian Aquatic Resources Section of the American Fisheries Society (AFS).

|Scallop “recruits” abundant on Georges Bank
The SMAST scallop video survey team reported its 2014 findings to the Fishermen’s Steering Committee last week: populations are up, particularly the numbers of small scallops and particularly on Georges Bank.
“The overall stock biomass measured in scallop meat weight is estimated to be 320 million lbs, a substantial increase from the 243 million lbs observed in 2012,” said SMAST Prof. Kevin Stokesbury, lead scientist of the annual video survey. “However, the extraordinary news is the huge number of new recruits, small scallops less than 3 inches that will reach commercial size in the next few years.”
The US sea scallop resource averages 8 billion animals, but large increases in scallop populations seem to occur once every 10 years or so. A population spike from 2003 has supported a large part of the fishery for the past 10 years. The increase seen this year on Georges Bank is even larger than that of 2003, increasing the total estimated resource to 26 billion scallops.
“If protected and managed correctly,” said Stokesbury, “these scallops could insure sustainable catches for the next decade similar to those over the past 10 years.”
The video survey was conducted this year from May to July cooperatively with the fishing industry.
