SPECIES PROFILE PROPOSAL FOR THE SCIENTIFIC BODIES OF SEAFO L.J. López-Abellán (1) , I. Figueiredo (2) and R. Sarralde (1) (1) Centro Oceanográfico de Canarias, Instituto Español de Oceanografía, Avda. Tres de Mayo nº 73, 38005 Santa Cruz de Tenerife, España; (2) Instituto de Investigação das Pescas e do Mar (IPIMAR - INRB),Av. Brasília, 1449-006 Lisboa, Portugal BACKGROUND Some regional organisations similar to SEAFO have promoted and adopted the creation of templates for compiling and summarising the best information about fisheries and species within their management areas (e.g. CCAMLR, SPRFMO). The aim of this species profile is to compile in a living document the current best available information about: i) the biology, ecology and population dynamics of the main species; ii) fisheries data; iii) facts or events affecting both the species and their environment; and iv) the evolution of their fisheries in the regional management area. This system would provide an easy and efficient form to update and consult the key information related to the target species that could be used in assessment models, management advice and ecosystem modelling. Thus, each organisation has decided its own model to develop such idea. Following the original model of standard template adopted by the South Pacific Regional Management Fisheries Organisation (SPRFMO), after several arrangements and simplifications, this paper presents a proposal to be analysed within the subsidiaries body’s of SEAFO in order to consider its suitability and the possibility of adoption. This proposal includes a species profile template (Annex I) which contains explanatory text to help to complete it, and two incomplete species profiles (Annex II) as an example of what we are proposing. 1 ANNEX I - SPECIES PROFILE TEMPLATE 2 <Species> Species Profile SEAFO South East Atlantic Fisheries Organisation <Insert picture> DRAFT (Updated: dd/mm/yy ) 3 Another situation of the sections Sec tion to be developed ….

Species characteristics 2.1 Distribution - Global and within South East Atlantic divisions and subdivisions . - Identification of potential straddling stocks. - Seasonal changes in the species distribution. 2.2 Habitat - General description of the ocean region where the species inhabits. - General description of the sea bottom which the species is related to. 2.3 Biological characteristics - Morphology, growth, longevity, natural mortality, fecundity, maturity, spawning season, food consumption and other life history characteristics …. 2.4 Population structure - General description of maximum size and weight, size structure, sex-ratio …. 4 - Identification of potential spatial structure changes. 2.5 Behavior and associated species - Aggregations, migrations, trophic level…. - Main species associated to the target species. 2.6 Resilience / productivity - Classification of fish population or species in relation to its resilience or productivity following Musick (1999) criteria: Parameter High Medium Low Very low Vulnerability threshold 0.99 0.95 0.85 0.70 rmax (1/year) >0.5 0.16-0.50 0.05-0.15 <0.05 k(1/year) >0.3 0.16-0.30 0.05-0.15 <0.05 Fecundity(1/year) >10 000 100-1000 10-100 <10 tm(years) <1 2-4 5-10 >10 tmax (years) 1-3 4-10 11-30 >30 2.7 Intrinsic vulnerability - Classification of the species vulnerability following Cheung et al (2005; 2007) criteria. Please note: - Effective conserv ation of threatened species requires timely identification of vulnerable species. Based on life history and ecological characteristics several authors (Cheung et al., 2005, 2007) presented a fuzzy expert system to estimate vulnerability to fishing, in which, four linguistic categories referring to the levels of intrinsic vulnerability: (1) very high vulnerability to extinction; (2) high vulnerability; (3) moderate vulnerability; and (4) low vulnerability are established. 3. Fisheries 3.1 Fleets - Description of fleets targeting the species and the fishing methods used. 3.2 Historical catch and effort data - Catch and effort review. - Differentiation should be made between data coming from data-mining from those obtained with the new SEAFO protocols. 3.3 Fishing activities - Description (temporal and spatial) of the current and past fishing activities taking place. - Consider here the yearly evolution of the fishing activities/operations in the area (e.g. by fleets, target resource, etc…). 3.4 Stock size 5 - Estimates of relative or absolute biomass. 3.5 Biological reference points - Estimates of relevant reference points based on fishing mortality (F); biomass (B); and others. (see http://www.fao.org/docrep/006/X8498E/x8498e0c.htm). 3.6 Fishery status and trends - Determination of the fishery status and trends in relation to relevant biological reference points. 3.7 Stock status - Estimation of the actual stock status Please note the FAO scale: - Current degree of exploitation of the stock, based on the following scale (FAO): ? (or blank) = Not known or uncertain. Not much information is available to make a judgment; U = Underexploited, undeveloped or new fishery. Believed to have a significant potential for expansion in total production; M = Moderately exploited, exploited with a low level of fishing effort. Believed to have some limited potential for expansion in total production; F = Fully exploited. The fishery is operating at or close to an optimal yield level, with no expected room for further expansion; O = Overexploited. The fishery is being exploited at above a level which is believed to be sustainable in the long term, with no potential room for further expansion and a higher risk of stock depletion/collapse; D = Depleted. Catches are well below historical levels, irrespective of the amount of fishing effort exerted; R = Recovering. Catches are again increasing after having been depleted or a collapse from a previous high. 4. Impact of Fishing 4.1 Incidental catch - Assessment of incidental catch of seabird, mammals, reptiles and protected fish species, in the fishing action targeting this species using pertinent observations. - Fishing impact has to be described by gears. 4.2 Habitat impact assessment - Assessment of habitat impact, in the action of fishing the species using pertinent observations. - Fishing impact has to be described by gears. 4.3 By-catch and discards 6 - Targeting studies on that matter should be referenced and also the results and conclusions. - Also analysis based on scientific observations should be used. 5. Management 5.1 Regulation measures - List of existing regulations measures adopted in relation to the stock. 5.2 Comprehensible fishery management - Detailed description on how the management measures are affecting the status of the stock. - Reflect when other aspects (exogenous factors, e.g. climate) that might contribute for changes on stock status are also considered. 5.3 Ecosystem-based vision - Trophic and associative implications should be considered. - Adaptative techniques and practices to reduce non-desirable impacts should be considered. 6. Research 6.1 Past and current research activities - Short description of target fisheries research, and research on resources and ecosystem conservation. 6.2 Further research proposal - Research priorities and how to implement them. 7.

Piscat. 46 (4): 287–291. Background. The study is a contribution to Project CELFISH which involves genetic identifi cation of populations of fi sh species presenting a particular economic importance or having a potential to be used in the so-called commercial substitutions. The EU fi sh trade has been showing a distinct trend of more and more fi sh species previously unknown to consumers being placed on the market. Molecular assays have become the only way with which to verify the reliability of exporters. This paper is aimed at pinpointing genetic markers with which to label and differentiate between two populations of splendid alfonsino, Beryx splendens Lowe, 1834, a species highly attractive to consumers in Asia and Oceania due to the meat taste and low fat content. Material and methods. DNA was isolated from fragments of fi ns collected at local markets in Japan (MJ) (n = 10) and New Zealand (MNZ) (n = 18). The rhodopsin gene (RH1) fragment and 16 microsatellite DNA fragments (SSR) were analysed in all the individuals.

RANDALL 2 ABSTRACT: The following fishes represent new records for the Hawaiian Islands: the moray eel Lycodontis javanicus (Bleeker), the frogfish Antennarius nummifer (Cuvier), the jack Carangoides ferdau (Forssk::U), the grouper Cromileptes altivelis (Cuvier) (probably an aquarium release), the chubs Kyphosus cinerascens (Forsskal) and K. vaigiensis (Quoy and Gaimard), the armorhead Pentaceros richardsoni Smith, the goatfish Upeneus vittatus (Forsskal) (a probable unintentional introduction by the Division of Fish and Game, State of Hawaii), the wrasse Halichoeres marginatus Ruppell,' the gobies Nemateleotris magnifica Fowler and Discordipinna griessingeri Hoese and Fourmanoir, the angelfish Centropyge multicolor Randall and Wass, the surgeonfish Acanthurus lineatus (Linnaeus), the oceanic cutlassfish Assurger anzac (Alexander), and the driftfish Hyperoglyphe japonica (Doderlein). In addition, the snapper Pristipomoides auricilla (Jordan, Evermann, and Tanaka) and the wrasse Thalassoma quinquevittatum (Lay and Bennett), both overlooked in recent compilations, are shown to be valid species for the Hawaiian region. Following Parin (1967), the needlefish Tylosurus appendicu­ latus (Klunzinger), which has a ventral bladelike bony projection from the end of the lower jaw, is regarded as a morphological variant of T. acus (Lacepede).
