ISBN 978-4-87803-036-9 Corresponding editor: Hiroyuki Motomura (e-mail: [email protected]) v Preface Tropical seas in Southeast Asian countries are well known for their rich fish diversity found in various environments such as beautiful coral reefs, mud flats, sandy beaches, mangroves, and estuaries around river mouths. The South China Sea is a major water body containing a large and diverse fish fauna. However, many areas of the South China Sea, particularly in Malaysia and Vietnam, have been poorly studied in terms of fish taxonomy and diversity. Local fish scientists and students have frequently faced difficulty when try- ing to identify fishes in their home countries. During the International Training Program of the Japan Society for Promotion of Science (ITP of JSPS), two graduate students of Kagoshima University, Mr. -

All rights reserved A ‘Gempylids’ (snake mackerels) and trichiurids (cutlassfishes) are pelagic fishes characterised by slender to eel-like bodies, deep-sea predatory ecologies, and large fang-like teeth. Several hypotheses of relationships between these groups have been proposed, but a consensus remains elusive. Fossils attributed to ‘gempylids’ and trichiurids consist almost exclusively of highly compressed body fossils and isolated teeth and otoliths. We use micro-computed tomography to redescribe two three- dimensional crania, historically assigned to †Eutrichiurides winkleri and †Progempylus edwardsi, as well as an isolated braincase (NHMUK PV OR 41318). -
Distribution, Abundance and Biological Interactions of the Cutlassfish Trichiurus Zepturus in the Southern Brazil Subtropical Convergence Ecosystem
ELSEVIER Fisheries Research 30 (1997) 217-227 Distribution, abundance and biological interactions of the cutlassfish Trichiurus Zepturus in the southern Brazil subtropical convergence ecosystem Agnaldo Silva Martins a,* , Manuel Haimovici b a Departamento de Ecologia e Recursos Naturais-Universidade Federal do Espirito Sante-Au. Fernando Ferrari, s/n, Vithia-ES, 29060-900, Braril h Departamento de Oceanograjia, Funda@o Uniuersidade do Rio Grande. Caixa Postal 474, Rio Grande, RS 96201-900. Brazil Accepted 5 October 1996 Abstract The distribution, abundance and biological interactions of the cutlassfish Tn’chiurus lepturus in the southern Brazil subtropical convergence ecosystem were studied from demersal trawl surveys conducted along the continental shelf and upper slope from Cape Santa Marta Grande (28”36’S) to Chui (34”45’S) between 1981 and 1987. Trichiurus lepturus was more abundant at bottom water temperatures of over 16°C and in the 40-120 m depth range. From late spring to fall, juveniles of S-30 cm total length (TL) were found in coastal waters, subadults (TL 30-70 cm) mainly in inner shelf waters and adults (TL > 70 cm) in coastal, inner and outer shelf waters. Higher catches of subadults and adults were found associated with thermal fronts in the western boundary of the Subtropical Convergence or with a shelf break upwelling observed in summer. The standing stock in a 58 000 km2 shelf area estimated by the swept area method, ranged from 3066 t ( f 46% Cl) in September 1981 to 37 8 14 t ( f 22% CI) in January 1982. Correlation between occurrences of different size groups of cutlassfishes and other fishes caught in 250 bottom trawl hauls was analyzed. -
Fish in Disguise: Seafood Fraud in Korea
Fish in disguise: Seafood fraud in Korea A briefing by the Environmental Justice Foundation 1 Executive summary Between January and December 2018, the Environmental Justice Foundation (EJF) used DNA testing to determine levels of seafood fraud in the Republic of Korea. The results showed that over a third of samples tested were mislabelled. This mislabelling defrauds consumers, risks public health, harms the marine environment and can be associated with serious human rights abuses across the world. These findings demonstrate the urgent need for greater transparency and traceability in Korean seafood, including imported products. Key findings: • Over a third of seafood samples (34.8%, 105 of 302 samples) genetically analysed were mislabelled. • Samples labelled Fleshy Prawn, Fenneropenaeus chinensis (100%), Japanese Eel, Anguilla japonica (67.7%), Mottled Skate, Raja pulchra (53.3%) and Common Octopus, Octopus vulgaris (52.9%) had the highest rates of mislabelling. • Not a single sample labelled Fleshly Prawn was the correct species. • Mislabelling was higher in restaurants, fish markets and online than in general markets or superstores. • By processed types, sushi (53.9%), fresh fish (38.9%) and sashimi (33.6%) were the most likely to be mislabelled. • The seafood fraud identified by this research has direct negative impacts for consumers. It is clear that for some species sampled consumers were likely to be paying more than they should. For example, more than half of the eel and skate samples that were labelled domestic were actually found to be imported, which can cost only half of the price of domestic products. Swordfish mislabelled as Bluefin Tuna can be sold for four to five times as much. -

This evaluation is based on the most recent comprehensive estimates of IUU fishing and includes the worlds’ major commercial stocks or species groups, such as all those that are regularly assessed by the United Nations Food and Agriculture Organization (FAO). Based on WWF’s findings, the majority of the stocks, 54 percent, are categorized as at high risk of IUU, with an additional 32 perent judged to be at moderate risk. Of the 567 stocks that were assessed, the findings show that 485 stocks fall into these two categories. More than half of the world’s most overexploited stocks are at the highest risk of IUU fishing. Examining IUU risk by location, the WWF analysis shows that in more than one-third of the world’s ocean basins as designated by the FAO, all of these stocks were at high or moderate risk of IUU fishing. -

3.1.2 LONGLINE CHAPTER 3.1.2: AUTHORS: LAST UPDATE: LONGLINE Domingo A., Forselledo R., Miller March 2014 P., Jiménez S., Mas F. and Pons M. 3.1.2 General description of longline fisheries 1. General description of longline gear and vessels Longline is a fishing gear that is comprised of a main line, with secondary lines attached and hooks placed on the end of them. Longline is a very old gear, derived from “volantín” or “three hook line”, which was used by the Phoenicians and the Egyptians in the Mediterranean Sea (Canterla, 1989). The word “longline” is possibly of Catalonian origin, and derived from southern Italian or Greece (Prat Sabater, 2006; González García, 2008). Since their beginnings and up to the 15th century at least, the longlines that were used were fixed, anchored to the coast with stalks. Later, in the open sea, “jeito” and “vareque” net gears were used which drifted while remaining moored to the vessels, and which could have given rise to drift gears, one of which is longline (Canterla, 1989). 1.a General description of pelagic longline 1.a.1 Introduction Drifting pelagic longline is used worldwide to catch widely distributed pelagic and semi-pelagic fish. This gear is very effective in catching tunas, billfish and sharks, among others (Doumenge, 1998; Matsuda, 1998). It consists of a main line or “mother” line, suspended in the water by secondary lines called float lines, which carry the floats. The branch lines hang from the main line and carry hooks on the ends. The characteristics of the materials, dimensions, types of floats and hooks, as well as the configuration of the lines are quite variable, depending mainly on the origin of the fleets, the fishermen and the target species. -

Guide to the Coastal Marine Fishes of California
STATE OF CALIFORNIA THE RESOURCES AGENCY DEPARTMENT OF FISH AND GAME FISH BULLETIN 157 GUIDE TO THE COASTAL MARINE FISHES OF CALIFORNIA by DANIEL J. MILLER and ROBERT N. LEA Marine Resources Region 1972 ABSTRACT This is a comprehensive identification guide encompassing all shallow marine fishes within California waters. Geographic range limits, maximum size, depth range, a brief color description, and some meristic counts including, if available: fin ray counts, lateral line pores, lateral line scales, gill rakers, and vertebrae are given. Body proportions and shapes are used in the keys and a state- ment concerning the rarity or commonness in California is given for each species. In all, 554 species are described. Three of these have not been re- corded or confirmed as occurring in California waters but are included since they are apt to appear. The remainder have been recorded as occurring in an area between the Mexican and Oregon borders and offshore to at least 50 miles. Five of California species as yet have not been named or described, and ichthyologists studying these new forms have given information on identification to enable inclusion here. A dichotomous key to 144 families includes an outline figure of a repre- sentative for all but two families. Keys are presented for all larger families, and diagnostic features are pointed out on most of the figures. Illustrations are presented for all but eight species. Of the 554 species, 439 are found primarily in depths less than 400 ft., 48 are meso- or bathypelagic species, and 67 are deepwater bottom dwelling forms rarely taken in less than 400 ft. -
