The Marine Board was established in 1995 to facilitate enhanced cooperation between European marine science organizations towards the development of a common vision on the research priorities and strategies for marine science in Europe. Members are either major national marine or oceanographic institutes, research funding agencies, or national consortia of universities with a strong marine research focus. In 2015, the Marine Board represents 36 Member Organizations from 19 countries. The Board provides the essential components for transferring knowledge for leadership in marine research in Europe. Adopting a strategic role, the Marine Board serves its member organizations by providing a forum within which marine research policy advice to national agencies and to the European Commission is developed, with the objective of promoting the establishment of the European marine Research Area. www.marineboard.eu European Marine Board Member Organizations UNIVERSITÉS MARINES Irish Marine Universities National Research Council of Italy Consortium MASTS Delving Deeper: Critical challenges for 21st century deep-sea research European Marine Board Position Paper 22 This position paper is based on the activities of the European Marine Board Working Group Deep-Sea Research (WG Deep Sea) Coordinating author and WG Chair Alex D.

Another essay of relationships between CPUE and environment. 4. REFERENCES APPENDIX List of tables. Tables. List of figures. Figures. INTRODUCTION Jack mackerel (Trachurus murphyi) is part of a multispecies pelagic fishery in northern Chile, which together with anchovy (Engraulis ringens) and sardine (Sardinops sagax), account for more of 75% of the weight and 90% of the value of the entire Chilean fishery. Catches of anchovy, which are used mainly for fish meal production, have decreased appreciably since 1970, while catches of the jack mackerel have increased. In 1978 jack macke rel comprised 33% by weight of the fish catch of Chile. This report reviews previous studies and presents original data on the biology, habitat, fisheries biology and fisheries oceanography of the jack mackerel fishery of Chile, and has been written as a contribution for a fu ture management of this fishery. General biology of Trachurus murphyi Trachurus is one three closely related genera (with Decapterus and Selar) of the carangid subfamily Carangidae.

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.

A pesar de la importancia económica de este recurso, se desconocen aspectos críticos de su biología, como las características y la dinámica de la atresia, que pueden afectar el rendimiento reproductivo. Hembras deT. murphyi capturadas en distintas estaciones de desove fueron analizadas para describir los patrones de prevalencia e intensidad de atresia. Se realizaron modelos lineales generales (GLM) usando prevalencia e intensidad de atresia como variables de respuesta e índice gonadosomático, factor de condición, temperatura de la superficie del mar, folículos postovulatorios y mes/año como variables predictoras.

  • SC-04-JM-04 Analysis of Jack Mackerel Otolith Microstucture
    4th Meeting of the Scientific Committee The Hague, Kingdom of the Netherlands 10 - 15 October 2016 SC-04-JM-04 Analysis of jack mackerel otolith microstucture Francisco Cerna & Guillermo Moran Fisheries Development Institute (IFOP) 9 Sept 2016 SC-04-JM-04 Analysis of jack mackerel otolith microstructure Francisco Cerna & Guillermo Moyano Age and Growth Section, Resource Assessment Department, Fisheries Research Division, Fisheries Development Institute (IFOP). ABSTRACT The microstructure analysis of juvenile jack mackerel (Trachurus murphyi) collected in the northern coast (Arica to San Antonio) off Chile was carried out. The otoliths were examined on posterior sagittal plane (postrostrum) by light microscopy. The general pattern of jack mackerel otolith growth shows the formation of secondary primordium (SP) that divided the sagittal plane of the otolith into a primary and secondary growth zone (PGZ and SGZ). The SP was formed between 23 to 51 days after hatching, and the SP formation in sagittal otolith is the same of the T. japonicus pattern, where the PGZ was enclosed by the SGZ in the dorsal, posterior and ventral areas, but not anteriorly (rostrum). The increment width profile along the post-rostrum radius of sagittae showed the characteristic curve of fish on early stages. The increment width increased gradually from 3,4 um of the first increment, peaked about of 20 um ranged 50 to 80 days, then became progressively narrow until they reached a value of 2,1 um at 170 days old. The relationship between length of fish and post-rostrum radium of otolith was described by a linear regression than explained the 90% of variance.

  • How Fish Are Caught
    How fish are caught Wild fish can be caught in a variety of different ways, from the traditional rod and line to traps and trawl nets large enough to capture a passenger airplane. Fishing gears can be categorized as either mobile/active or static/passive depending on whether they are towed across the seabed or fixed to it. Mobile/active gear includes any trawls, trolling and drifting nets or lines whereas static/passive gear includes fixed nets, traps and rod and line. Generally static /passive gear has a lower impact on the seabed. Here are the most commonly used fishing methods with a brief explanation of how they work and their environmental impacts. Beam trawl In this type of trawl, the mouth or opening of the net is kept open by a beam, which is mounted at each end on guides or skids which travel along the seabed. The trawls are adapted and made more effective by attaching tickler chains (for sand or mud) or heavy chain matting (for rough, rocky ground) depending on the type of ground being fished. These drag along the seabed in front of the net, disturbing the fish in the path of the trawl, causing them to rise from the seabed into the oncoming net. Electrified ticklers, which are less damaging to the seabed, have been developed but used only experimentally. Work is also being carried out to investigate whether square mesh panels (see below) fitted in the ‘belly’ or lower panel of the net can reduce the impact of beam trawling on communities living on or in the seabed.
