of Reference As indicated in the ICES Annual Report for 2002, ICES Council Resolution 2002/2G01 stated that the Working Group on Cephalopod Fisheries and Life History [WGCEPH] (Chair: Dr .J.P. Robin, France) would meet in Lisbon, Portugal from 4-6 December 2002 to: a) update currently available landing statistics and information on fishing effort and discards and gear selectivity; explore existing resource survey databases for information about sampled cephalopods in the ICES area; b) compile methods and results available for stock identification and estimation of population size of fished cephalopods; c) identify possible precautionary approaches to the management of these cephalopod resources; and provide management options. d) compile available data and identify relationships between abundance and environmental conditions, factors affecting recruitment, migration and distribution patterns of juveniles and adults, and trophic interactions; e) review cephalopod culture techniques and results and their interest in the understanding of biological phenomena. f) update the bibliographic database of cephalopod literature relevant to fisheries, including grey literature; WGCEPH will report by the end of April 2003 for the attention of the Living Resources Committee, ACFM and ACE. 1.2 Attendance The WGCEPH meeting at the Tivoli Tejo Hotel, Lisbon, 5-6 December 2002, was attended by 11 of the currently appointed WGCEPH members.

En total, achéganse nomes galegos para 534 especies de moluscos. A estrutura En primeiro lugar preséntase unha clasificación taxonómica que considera as clases, ordes, superfamilias e familias de moluscos. Aquí apúntase, de maneira xeral, os nomes dos moluscos que hai en cada familia. A seguir vén o corpo do documento, onde se indica, especie por especie, alén do nome científico, os nomes galegos e ingleses de cada molusco (nalgún caso, tamén, o nome xenérico para un grupo deles). Ao final inclúese unha listaxe de referencias bibliográficas que foron utilizadas para a elaboración do presente documento. Nalgunhas desas referencias recolléronse ou propuxéronse nomes galegos para os moluscos, quer xenéricos quer específicos. Outras referencias achegan nomes para os moluscos noutras linguas, que tamén foron tidos en conta. Alén diso, inclúense algunhas fontes básicas a respecto da metodoloxía e dos criterios terminolóxicos empregados. 2 Tratamento terminolóxico De modo moi resumido, traballouse nas seguintes liñas e cos seguintes criterios: En primeiro lugar, aprofundouse no acervo lingüístico galego. A respecto dos nomes dos moluscos, a lingua galega é riquísima e dispomos dunha chea de nomes, tanto específicos (que designan un único animal) como xenéricos (que designan varios animais parecidos).

Thank you for always believing in me. ii ACKNOWLEDGMENTS I would like to thank all of the people who helped me collect the specimens for this study, braving the rocks and the waves in the middle of the night: Leigh Ann Boswell, Shannon Evers, and Steffiny Nelson, you were the hard core tako hunters. I am eternally grateful that you sacrificed your evenings to the octopus gods. Also, thank you to David Harrington (best bucket boy), Bert Tanigutchi, Melanie Hutchinson, Christine Ambrosino, Mark Royer, Chelsea Szydlowski, Ily Iglesias, Katherine Livins, James Wood, Seth Ylitalo-Ward, Jessica Watts, and Steven Zubler. This dissertation would not have happened without the support of my wonderful advisor, Dr. Les Watling. Even though I know he wanted me to study a different kind of “octo” (octocoral), I am so thankful he let me follow my foolish passion for cephalopod sexual selection. Also, he provided me with the opportunity to ride in a submersible, which was one of the most magical moments of my graduate career.

  • Mercury Levels of Seafood Commonly Consumed in Taiwan
    373 Journal of Food and Drug Analysis, Vol. 14, No. 4, 2006, Pages 373-378 藥物食品分析 第十四卷 第四期 Mercury Levels of Seafood Commonly Consumed in Taiwan Y. C. CHEN1,2 AND M. H. CHEN2* 1. Department of Food Nutrition, Chung Hwa College of Medical Technology, Jen-Te Hsiang, Tainan 717, Taiwan, R.O.C. 2. Department of Marine Biotechnology and Resources, National Sun Yat-sen University, Kaohsiung City 80424, Taiwan, R.O.C. (Received: February 14, 2006; Accepted: June 26, 2006) ABSTRACT In this study, the mercury level in 25 commonly consumed seafood species was identified and used to evaluate the mercury intake for Taiwan population. Total mercury concentrations were determined by using furnace-gold amalgation mercury analyzer. The results indicated that mercury concentrations of the 25 seafood species ranged from 0.002 to 0.198 mg/kg wet wt. and varied significantly across species (p < 0.05). All mercury concentrations of the 25 seafood species were below the safety standards, 0.5 mg/kg, set by TWDOH, EC and FAO/WHO. Mercury intake from seafood consumption for female and male adults in Taiwan was estimated to be 21 and 30 μg/week, respectively, which was well below the PTWI. Among the seafood items tested, fish was the major source of total mercury intake for Taiwan population (74-83%). The marine fish contributed the most, followed by shellfish and freshwater fish. The highest mercury level was found in tuna. The mercury intake could be within the PTWI if general popu- lation weighted 65 kg consumed daily 90 g of seafood with mercury concentration as 0.17 mg/kg.

BOX 297, Concepcio´n, Chile In this research we studied the diet of Enteroctopus megalocyathus from three principal locations of the octopus fishery (Ancud, Quello´n and Melinka) in southern Chile. The gastric contents of 523 individuals, collected between October 1999 and September 2000, were examined and statistically analysed. Diet composition was described using detrended correspon- dence analysis and analysed as a function of predator gender, body size and fishing area. Food items were found in ~50% of the octopuses examined and a total of 14 prey items were recognized. The diet of E. megalocyathus consisted primarily in brachyuran and anomuran crustaceans, fish and conspecifics. The diet differed in composition between fishing zones and mantle length of the specimens and size of octopuses varied between locations. After adjusting for octopus mantle length, diet composition was found to be different between fishing areas. Large octopuses fed on large crabs at Ancud, while in Quello´n and Melinka small octopuses fed mainly on small crustaceans. There were no differences in prey composition between the gender and the size of octopuses was a better predictor of the variance in the diet composition (16%) than the fishing zone (6%).

  • Feeding Habits of an Exotic Species, the Mediterranean Green Crab Carcinus Aestuarii, in Tokyo Bay
    Feeding habits of Car cinus aestuarii RB Chen et al. 10.1046/j.1444-2906.2004.00822.x Original Article430435BEES SGML FISHERIES SCIENCE 2004; 70: 430–435 Feeding habits of an exotic species, the Mediterranean green crab Carcinus aestuarii, in Tokyo Bay Rong Bin CHEN, Seiichi WATANABE* AND Masashi YOKOTA Department of Aquatic Biosciences, Tokyo University of Marine Science and Technology, Minato, Tokyo 108-8477, Japan ABSTRACT: Feeding habits of an exotic species, the Mediterranean green crab Carcinus aestuarii, in Tokyo Bay, Japan, were studied based on the analysis of stomach contents. Monthly samples were taken from May 2000 to October 2001 at stations near the Keihin Canal along the northern shore of Tokyo Bay. Stomach contents of 367 crabs (male n = 200, female n = 167) were examined. Carapace width ranged from 18.50 mm to 60.67 mm. Eleven food categories were identified: Bivalvia (mostly Mytilus galloprovincialis), other Mollusca, Cirripedia, Amphipoda, Brachyura, other Crustacea, Poly- chaeta, Pisces, unidentified animal materials, plant materials, and unidentified materials. The results showed that C. aestuarii is an omnivorous predator and that its diet depends greatly upon the availability of local prey species, especially in intertidal areas. Moreover, the analysis found no significant differences in the feeding habits of crabs of different sizes or sexes. KEY WORDS: Carcinus aestuarii, exotic species, feeding habits, stomach contents, Tokyo Bay. INTRODUCTION that they were scavengers and predators. The bulk of their prey consisted of slow-moving and sessile Many exotic species have established natural invertebrates, with algae comprising only a small populations in Japan in recent years.
