PRESIDENT’S MESSAGE BY JIM BOWKER It’s with a bit a trepidation that I sit down to write my first President’s message because the reality that I’m about to be handed the “keys to the car” is imminent. I’m about to assume the responsibility of helping to lead the Section and its nearly 500 members, and try to make the Section better tomorrow than it is today. That’s a tall order because my predecessors have set the bar pretty high. Recent Presidents Mike Barnes (2005–2007) and Curry Woods (2007 -2009) and outgoing President Jesse Trushenski each possess a unique skill set that has really helped put the Section back on the map. I am so pleased that we’re receiving more attention from ‘Big AFS’ than we have in the past, and that other aquaculture societies have taken notice of our Section’s accomplishments and have expressed their interest in doing more collaborative projects. Mike claims that he is just a talker, and that occasionally he’ll come up with a

“It’s been an honor and privilege to follow in the footsteps of these folks, and to work closely with Jesse getting things done.”

good idea that others in the Section will run with—anyone who knows Mike knows that his enthusiasm is infectious and has done more than a few good things for the Section. Curry can talk the fuzz off a peach, has a ton of great ideas, and has the brass to step up to represent the Section and the role of fish culture at AFS Governing Board meetings and other venues. Jesse brings all that and more. She often dons her SuperWoman cape and simply gets things done. It’s been an honor and privilege to follow in the footsteps of these folks, and to work closely with Jesse getting things done. As I reread the last sentence, I think to myself how many times I’ve heard somebody make that exact statement, how it sounds awfully nice, but what does it really mean? To get a better understanding of what it means to me, I need to share with you what I had in mind when I agreed to become more actively involved in the Section. I found it a bit disheartening, but justified, when I’d hear from friends that are fish culturists or associated (Continued on page 2)

President’s Message (continued) (Continued from page 1)

“I strongly believe that if we can get folks to become Affiliate Members, we’ll have a better opportunity to show them that there are benefits to becoming AFS Members.”

with fish culture in some capacity (e.g., fish health biologists, researchers) that they’re not members of AFS, let alone the Section, because there was little direct benefit to them. Many folks I talked to attend various fish culture meetings (e.g., Aquaculture America, Northwest Fish Culture Conference, Coolwater Fish Culture Workshop, Eastern or Western Fish Health Workshops) and have found that AFS meetings do not offer much of an opportunity to exchange research findings and other information that they find interesting and beneficial. Jesse and I talked at length about what the Section can do to get folks to feel like there are unique advantages to being a member, and that members are not just simply supporting our organization by sending in their dues year after year. We challenged ourselves to provide our members with tools and information that might help them do their jobs better, to provide a better mechanism to communicate useful information to one another, and to stand up and be a presence at the Big AFS level. I am so pleased that, working together or in collaboration with others, we have been able to develop products that should be useful to our members (e.g., approved drug and licensed vaccine posters, Guide to Using Drugs, Biologics, and Other Chemicals in Aquaculture and companion treatment calculator, AFS Policy Statement on the Need for Immediate-release Fish Sedatives, Applied Aquaculture Notes series). This has put me in a much better position to try to address another goal – to increase Section membership. During the past two years, I’ve taken advantage of virtually every opportunity to talk about the Section, what we hope to accomplish in the near and distant future, and point to the products we’ve developed and let folks know that these are available to

members. Frankly, we’ve found it challenging to convince folks, especially those who spend their time getting their hands wet dealing with fish rather than sitting behind a computer, that there are tangible benefits to becoming an active AFS member. That’s why we’ve put so much effort into promoting Affiliate Membership. I strongly believe that if we can get folks to become Affiliate Members, we’ll have a better opportunity to show them that there are benefits to becoming AFS Members. The last part is going to be the most challenging, and the part I’ll approach with the greatest amount of anxiety. For those that have met me, you know that when I’m in a comfortable environment I tend to speak my mind, wear my emotions on my sleeve, and always have one last thing to say. For the sake of the Section, I hope that I can channel this and represent the Section well and continue the efforts of my predecessors in repaving the road to annual AFS meetings being first and foremost in the minds of fish culturists when it comes to the meeting of choice. This will be a huge task that may or may not be achievable, will take quite a bit of time to accomplish, and will require the support of Section members, friends, and colleagues around the country. All the projects and strategies that I’ve had the privilege of working on with our outgoing President, and all the plans that I’ll have the privilege of working on with our incoming President-Elect will hopefully get us one step closer to our goal: making AFS and the Section relevant to fish culturists and those associated with fish culture. I want to let you know that it’s also a privilege to represent you, and I vow to burn the midnight candle working on your behalf in an effort to make you truly feel the benefits of being an AFS FCS Member.

Aquaculture now supplies half of the seafood and fisheries products consumed worldwide and is gaining international significance as a source of food and income. Future demands for seafood and fisheries products can only be met by expanded aquaculture production. Such production will likely become more intensive and will depend increasingly on nutritious and efficient aquaculture feeds containing ingredients from sustainable sources. To meet this challenge, Nutrient Requirements of Fish and Shrimp provides a comprehensive summary of current knowledge about nutrient requirements of fish and shrimp and supporting nutritional science. This edition incorporates new material and significant updates to information in the 1993 edition. It also examines the practical aspects of feeding of fish and shrimp. Nutrient Requirements of Fish and Shrimp will be a key resource for everyone involved in aquaculture and for others responsible for the feeding and care of fish and shrimp. It will also aid scientists in developing new and improved approaches to satisfy the demands of the growing aquaculture industry. Available now! As a special offer, National Academies Press, the publisher for the IOM, is offering a 25% discount off the list price of the book. Please enter promotional code FFISH in the NAP shopping cart to take advantage of the discount. NAP also offers examination copies of titles for professors considering a title for course adoption.

OCEANS: White House releases draft water policy By: John McArdle Source: (Thursday, June 2, 2011) The National Ocean Council today released a series of draft action plans aimed at addressing some of the most pressing challenges facing U.S. oceans and coasts and the Great Lakes. Taken together, the nine action plans will help create a framework around which the White House's new National Ocean Policy will be built. The policy, which President Obama set in motion with an executive order last year, is aimed at improving coordination and planning for a wide range of issues -- from preparing for climate change impacts on coastal communities to regulating offshore wind farms and oil drilling. In a presidential proclamation today celebrating June as National Oceans Month, Obama praised the policy as a way to more effectively use federal resources. "While we embrace our oceans as crucial catalysts for trade, bountiful sources of food and frontiers for renewable energy, we must also recommit to ensuring their safety and sustainability and to being vigilant guardians of our coastal communities," Obama said. The release of the strategic plans today comes ahead of a 12-city listening tour that experts from the National Ocean Council will conduct next week through July 1. The council, made up of representatives of 27 agencies with oversight roles in the oceans and Great Lakes, is looking for public feedback before finalizing those plans sometime early next year. The first listening session will take place on June 9 in Arlington, Va. "I think the people who are interested and care about the oceans and depend on the oceans have a lot to tell us, and we have a lot to learn from them, so I think these listening sessions will be very helpful," said Council on Environmental Quality Chairwoman Nancy Sutley, who also serves as a co-chair of the National Ocean Council. "We've done our best to try to identify issues, but there are things that really do affect communities -whether it's how we manage fisheries, how we manage energy production, even things related to shipping and air pollution. So that's what we're trying to get from these sessions," Sutley said.

The action plans include several efforts that have garnered broad-based support, such as better educating the public about oceans, coasts and the Great Lakes. But one of the plans involves the somewhat controversial practice called coastal and marine spatial planning, a process that would take some principles of zoning to the sea. Ocean experts and the Obama administration have been pushing for a marine planning effort to address growing demand to use the ocean for activities that can conflict, such as drilling, shipping, fishing, aquaculture, renewable energy development and recreation. The draft action plan that was released today calls for a regional approach to the marine planning effort to allow the unique geographic, economic and social aspects of different regions of the country to guide the development of those plans. But the plan also acknowledges that preparing spatial plans "may create a level of anxiety" among those who rely on the oceans' resources and that frequent engagement among the public, stakeholders and the government will be essential to making the effort a success. "It's a concept that evokes strong emotions on both sides of the argument," said Michael Conathan, who serves as director of ocean policy for the Center for American Progress. "It's something that is somewhat in need of further definition because it means different things to different people." For example, the fishing industry has expressed concerns that the process could force fishermen out of areas they have long considered open. But some offshore wind energy developers view the process as an opportunity to overcome some of the hurdles and red tape that come with developing their projects. "When you have different people vying for the use of ocean space, you have to find a way to balance the needs of those potentially conflicting user groups," Conathan said. But Conathan suggested that spatial planning works best when it is used as more of a philosophy, applied on an "as needed" basis. "When you are dealing with an area larger than the (Continued on page 13)

A F S F i s h C u l tu r e S e c ti o n (Continued from page 12)

landmass of the country, you can't plan for every inch," he said. Another concern that some ocean industry groups have raised about the National Ocean Policy effort is the fear that it might add another layer of red tape for those industries that already deal with a vast amount of federal regulation. "We believe that a key challenge for any ocean policy is to implement policy that fully recognizes and works with the many existing laws and regulations that govern activities in the marine environment," said Rick Ranger, senior policy adviser for the American Petroleum Institute. Ranger said that better coordination among the many agencies that share jurisdiction over ocean activities is certainly a desirable goal.

"But we don't think there's either the need or legal authority for a program that would reinvent the wheel in particular for offshore oil and gas activities," he said. The National Ocean Policy "should work within the existing framework and not try to superimpose new and more restrictive policies on top of it." But Sutley said that the status quo has some real limitations. "We're not looking to develop a whole separate regulatory process," she said. "We believe we can do this under current authorities and current regulations." What the action plans are trying to accomplish is "getting folks together to talk about issues before they get too far to try to reduce potential conflict," Sutley said.

Two Pesticides -- Rotenone and Paraquat -- Linked to Parkinson's Disease, Study Suggests Science Daily (Feb. 15, 2011) — New research shows a link between use of two pesticides, rotenone and paraquat, and Parkinson's disease.

Fish Oil's Impact On Cognition and Brain Structure Identified in New Study Science Daily (Aug. 17, 2011) — Researchers at Rhode Island Hospital's Alzheimer's Disease and Memory Disorders Center have found positive associations between fish oil supplements and cognitive functioning as well as differences in brain structure between users and non-users of fish oil supplements. The findings suggest possible benefits of fish oil supplements on brain health and aging.

Daiello says, "In the imaging analyses for the entire study population, we found a significant positive association between fish oil supplement use and average brain volumes in two critical areas utilized in memory and thinking (cerebral cortex and hippocampus), as well as smaller brain ventricular volumes compared to non-users at any given time in the study. In other words, fish oil use was associated with less brain shrinkage in patients taking these The results were reported at the recent International supplements during the ADNI study compared to Conference on Alzheimer's Disease, in Paris, France. those who didn't report using them." The study was led by Lori Daiello, PharmD, a research scientist at the Rhode Island Hospital Alzheimer's Disease and Memory Disorders Center. Data for the analyses was obtained from the Alzheimer's Disease Neuroimaging Initiative (ADNI), a large multi-center, NIH-funded study that followed older adults with normal cognition, mild cognitive impairment, and Alzheimer's Disease for over three years with periodic memory testing and brain MRIs.

Daiello continues, "These observations should motivate further study of the possible effects of long -term fish oil supplementation on important markers of cognitive decline and the potential influence of genetics on these outcomes." The research team included Brian Ott M.D., director of the Rhode Island Hospital and Memory Disorders Center, Assawin Gongvatana Ph.D., Shira Dunsiger Ph.D. and Ronald Cohen Ph.D. from The Miriam Hospital and the Brown University Department of Psychiatry and Human Behavior (Gonvatana and Cohen), and Department of Behavior and Social Sciences (Dunsiger).

The study included 819 individuals, 117 of whom reported regular use of fish oil supplements before entry and during study follow-up.
