I have already met participants from Australia; Kotzebue, Alaska; Lincoln, Nebraska; Hawaii; Florida; Texas; andOF Maryland, to name a few of the more distant places. I especially want to welcome our distinguished panel of speakers who represent the finest minds available on their respective topics in the United States. We value your contributions and appreciateOUT your willingness to share your expertise with us. We hope your stay here will be rewarded with new knowledge, new friendships, and continuedIS enthusiasm for the study of sharks. A conference like this doesn't just happen. It takes lots of planning and working on details. I want to acknowledge our organizing committee chaired by Bob Jacobson, Marine Agent in Newport, Oregon, and including Sid Cook, Marine Biologist with Argus-Mariner Consulting Biologists who master-minded the program of speakers; Tom Gentle, Communications Specialist with our Extension/Sea Grant Programinformation: in Corvallis who handled all of the fliers, programs, and news releases; and Bob Schoning, Senior Policy Advisor, Northwest and Alaska Fisheries Center, National Marine Fisheries Service, who kept a burr under our collective tails and insisted that we leave nothing to chance. We received outstanding staff support from Ginny Goblirsch who recorded registration details, Sandy Enschede who administered travel and financial details, Mary Gosla whocurrent assembled the displays, and others of our staff who contributedPUBLICATION in many ways. This conference is sponsored by the Pacific Association of Sea Grant Colleges including the University of Alaska Sea Grant College Program, the University mostof Hawaii Sea Grant College Program, the Oregon State University THISSea Grant College Program, the University of Washington Sea Grant College Program, and the University of Southern California Sea Grant College Program.

OF OUT IS information: PUBLICATIONcurrent most THIS For http://extension.oregonstate.edu/catalog Why Are We Talking About Sharks? Robert W. Schoning Senior Policy Advisor Northwest and Alaska Fisheries Center National Marine Fisheries Service Oregon State University Corvallis, OR 97331 DATE. Who cares about sharks? Many people all over the world do and for a great variety of reasons. So do all of you fine people in thisOF room. I will highlight a few of the reasons and the 24 speakers following me will give you more detail. Sharks are found all over the world and are increasing in importance and use. We are talking about them during these two days because it has been several years since there was a significant national conference on such a broad range of shark related subjectsOUT as this one. Much is being discovered about sharks and we felt it would be very worthwhile to have many of the nation'sIS recognized authorities on sharks meeting together and report on some of their latest findings and provide material for a published proceedings for use by scientists, commercial and recreational fishermen, marine water sport enthusiasts, fish processors, and consumers. In all fairness, you are not goinginformation: to learn all there is to know about sharks in these two days, notwithstanding the array of experts we have assembled, but you will be exposed to much extremely interesting information and be afforded the opportunity to talk with these recognized authorities on matters of particular interest to you. Have you looked at the program in detail? We have 24 different individuals talking about their specialties. They include by profession: six professors of biology, ichthyology, or zoology, six marine biologists,current five marine extension agents, one each of clinical PUBLICATIONphychotherapist, assistant editor, fisheries marketing specialist, marine business specialist, seafood consumer specialist, fish processor, research manager, sport fishing tackle shop operator, charter boat fisherman, and a chef. Ever sincemost the movie "Jaws," there has been greater public interest in THISsharks and potential shark attacks on swimmers. We have six speakers covering various aspects of shark-man relationships, including a newspaper man (how the mediaFor covers such incidents). You will learn that verified shark attacks are not nearly as common as many people think, but it is important that we discuss them to learn more about their frequency, severity, and actions we can or should takehttp://extension.oregonstate.edu/catalog to minimize danger and injury. Sharks are not the ferocious man-seeking, man-eating monsters too often portrayed in the media. Most of the people in this country are spending more time in pursuit of leisure activities including fishing, swimming, and surfing. Depending on the part of the country in which we live, we may encounter sharks in any or all three of these activities. We will learn about diving with them and fishing for them. We have people who have devoted significant parts of their lives to doing those things and learning much from their experiences. They will share their knowledge with us and I am sure you will find it most interesting and particularly useful if you participate in similar activities. The present annual world commercial catch of fish is about 76 million metric tons. There is an increasing demand for more marine proteinDATE. for human food. Present annual world landings of sharks, rays, and ratfishes is about 600,000 metric tons or 0.8% of the total. In some parts of the world these species are fished heavily and are overfished. In other areas they are underutilized for various reasons. OF Little is known about their abundance or distribution, or how to catch them, prepare them, find a market for them, and sell them at profit. Those aspects do not in any way detract from the nutritional benefits of many species of shark meat. More people should knowOUT how tasty shark can be. Those who were at the cocktail party last night were fortunate in being able to try mako, angel, sixgill, and dogfish sharksIS prepared in various ways. I assume they found them to be as delicious as I did. I am convinced one of the reasons a lot more people don't eat shark is that they don't know how good it tastes and how good it is for them. If more people would ask their butchers or restauranteurs for it they would be able to enjoy it more often. I am reminded of an ad for Kaiser aluminum foil, a sponsor of the Bonanza show that used to be on TV years ago.

  • Sylvia Earle Background Information
    Sylvia Earle Background Information Birth and Childhood Home She was born in Gibbs town, NJ on August 30, 1935. Her early childhood years were on a farm where there were many woods to explore. One of her favorite places was a pond. Her parent, particularly her mother was very influential in teaching her respect for animals. She always emphasized putting animals back where they were found after observing them. Sylvia took notes as a young child on the things that she observed. They also taught her not to fear the unknown. Horseshoe Crab Story Sylvia as a little girl at the beach was curious about the horseshoe crabs and how they moved. She was also concerned that they were stranded on the beach. She tried to pick them up, turn them around and sent them back to the ocean, not realizing that they were coming up on shore to lay their eggs and that she was really interfering with their mating. (see additional notes on horseshoe crabs) Reading As a child she liked to read. She liked science fiction, fairy tales, and animal stories. As she got a little older, she found that she liked non-fiction books even better. One of her favorite books was by William Beebe name Half Mile Down. He wrote about going down in the ocean in a vehicle like a submarine. In her book Sea Change and some of her other writings and interviews she refers to it frequently. After reading that book she started reading more non-fiction books and began liking the encyclopedia.

    A5 By-catch Species APPENDIX 5: BY-CATCH SPECIES A.5 By-catch species By-catch is the unintentional/incidental capture of non-target species during fishing operations. Different types of fisheries have different types and levels of by-catch, depending on the gear used, the time, area and depth fished, etc. Article IV of the Convention states: "the Commission shall be responsible for the study of the population of tuna and tuna-like fishes (the Scombriformes with the exception of Trichiuridae and Gempylidae and the genus Scomber) and such other species of fishes exploited in tuna fishing in the Convention area as are not under investigation by another international fishery organization". The following is a list of by-catch species recorded as being ever caught by any major tuna fishery in the Atlantic/Mediterranean. Note that the lists are qualitative and are not indicative of quantity or mortality. Thus, the presence of a species in the lists does not imply that it is caught in significant quantities, or that individuals that are caught necessarily die.

  • Tiger Shark (Galeocerdo Cuvier) on the East Coast of Australia
    The biology and ecology of the tiger shark (Galeocerdo cuvier) on the east coast of Australia. Bonnie Jane Holmes BSc (Hons) A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2015 School of Biological Sciences ABSTRACT The tiger shark (Galeocerdo cuvier) (Péron and Lesueur 1822) is the largest of the carcharhinids, with a circumglobal distribution in both tropical and warm temperate coastal and pelagic waters. In the western Pacific, G. cuvier movements are wide-ranging, encompassing the east coast of Australia and south Pacific Islands. Throughout the region, G. cuvier is exposed to a range of commercial, recreational, artisanal and illegal foreign fishery impacts, as both a target and by-product species. Listed as ‘near threatened’ on the International Union for Conservation of Nature (IUCN) Red List, suitable long term species-specific catch, catch rate and biological data are seldom available for large shark species like G. cuvier, particularly where historical commercial fishery logbook reporting has been poor. Shark control programs targeting large sharks along Australia’s east coast have been in operation for over 60 years, using relatively standardised fishing gear in nearshore waters all year round, with historical catch and effort data recorded by shark contractors. Historical catch, catch rate and biological data collected through the Queensland Shark Control Program (QSCP) since 1993 were investigated, which revealed significant declines (p < 0.05) in catch rates of G. cuvier at some tropical and all sub-tropical locations along the Queensland coast. Significant temporal declines in the average size of G. cuvier also occurred at four of the nine locations analysed (p < 0.05), which could be indicative of fishing reducing abundance in these areas.

Bull. 37(5) 709–721 (2014) 709 Review Total Purine and Purine Base Content of Common Foodstuffs for Facilitating Nutritional Therapy for Gout and Hyperuricemia Kiyoko Kaneko,*,a Yasuo Aoyagi,b Tomoko Fukuuchi,a Katsunori Inazawa,a and Noriko Yamaokaa a Laboratory of Biomedical and Analytical Sciences, Faculty of Pharma Sciences, Teikyo University; 2–11–1 Kaga, Itabashi, Tokyo 173–8605, Japan: and b Department of Health and Nutrition, Kagawa Nutrition University; 3–9–21 Chiyoda, Sakado, Saitama 350–0288, Japan. Received December 14, 2013; accepted February 17, 2014; advance publication released online February 20, 2014 Purines are natural substances found in all of the body’s cells and in virtually all foods. In humans, purines are metabolized to uric acid, which serves as an antioxidant and helps to prevent damage caused by active oxygen species. A continuous supply of uric acid is important for protecting human blood vessels. However, frequent and high intake of purine-rich foods reportedly enhances serum uric acid levels, which re- sults in gout and could be a risk factor for cardiovascular disease, kidney disease, and metabolic syndrome. In Japan, the daily intake of dietary purines is recommended to be less than 400 mg to prevent gout and hy- peruricemia. We have established an HPLC method for purine analysis and determined purines in a total of 270 foodstuffs. A relatively small number of foods contained concentrated amounts of purines. For the most part, purine-rich foods are also energy-rich foods, and include animal meats, fish meats, organs such as the liver and fish milt, and yeast.
