| A cytoplasmic dsRNA virus, rotifer birnavirus (RBV), has recently been isolated from the rotifer Brachionus plicatilis and is associated with a high mortality rate. Histologically, the viral lesions consist of characteristic inclusions, particularly amorphous dense bodies containing occluded particles. Purified virions are about 59 nm in diameter, single-shelled and display four capsomers per edge. The purified virions have a buoyant density of 1.290 (full particles) and 1.250 (empty particles) in CsCI gradients. Four major structural polypeptides of Mrs 60K, 52K, 33K and 27K were detected by SDS-PAGE. The genome is composed of two linear segments of dsRNA with Mrs of 2.45 x 106 and 2.31 × 106; additionally, small circular ssRNA molecules were detected by... |

| The blue shark Prionace glauca, among the most common and widely studied pelagic sharks, is a top predator, exhibiting the widest distribution range. However, little is known about its population structure and spatial dynamics. With an estimated removal of 10 to 20 million individuals per year by fisheries, the species is classified as “Near Threatened” by International Union for Conservation of Nature. We lack the knowledge to forecast the long-term consequences of such a huge removal on this top predator itself and on its trophic network. The genetic analysis of more than 200 samples collected at broad scale (from Mediterranean Sea, North Atlantic and Pacific Oceans) using mtDNA and nine microsatellite markers allowed to detect signatures of genetic... |

| The scope of the European Union Plan of Action for Sharks covers directed commercial, by-catch commercial, directed recreational, and by-catch recreational fishing of any chondrichthyans within European Union waters. It also includes any fisheries covered by current and potential agreements and partnerships between the European Union and third countries, as well as fisheries in the high seas and fisheries covered by RFMOs managing or issuing non-binding recommendations outside European Union waters. Scientific advice for the purpose of the management of shark species in the high seas is carried out mainly via the Scientific Committees of the relevant Regional Fisheries Management Organisations (RFMO), as well as through specific projects by national... |

| Effective ocean management and the conservation of highly migratory species depend on resolving the overlap between animal movements and distributions, and fishing effort. However, this information is lacking at a global scale. Here we show, using a big-data approach that combines satellite-tracked movements of pelagic sharks and global fishing fleets, that 24% of the mean monthly space used by sharks falls under the footprint of pelagic longline fisheries. Space-use hotspots of commercially valuable sharks and of internationally protected species had the highest overlap with longlines (up to 76% and 64%, respectively), and were also associated with significant increases in fishing effort. We conclude that pelagic sharks have limited spatial refuge from... |

| ISSF, in collaboration with other bycatch mitigation projects, such as the EU MADE project and the ORTHONGEL bycatch project, has undertaken tagging experiments to quantify the fishery impact on silky sharks (Carcharhinus falciformis) incidentally captured in the global tropical tuna purse seine fishery. Silky sharks commonly associate with floating objects in the open ocean environment. This phenomenon has been observed throughout the species’ cosmopolitan distribution range. Several other pelagic and coastal species also display this behaviour, but its prevalence in three tropical tuna species (skipjack, Katsuwonus pelamis, yellowfin, Thunnus albacares, and bigeye T. obesus, tunas) has led to the commercial exploitation of this behaviour. Industrial... |

| Tuna fisheries have been identified as one of the major threats to populations of other marine vertebrates, including sea turtles, sharks, seabirds and marine mammals. The development of technical mitigation measures (MM) in fisheries is part of the code of conduct for responsible fisheries. An in-depth analysis of the available literature regarding bycatch mitigation in tuna fisheries with special reference to elasmobranchs was undertaken. Studies highlighting promising MMs were reviewed for four tuna fisheries (longline, purse seine, driftnets and gillnet, and rod and line – including recreational fisheries). The advantages and disadvantages of different MMs are discussed and assessed based on current scientific knowledge. Current management measures for... |

| There is a need to better understand the survivorship of discarded fishes, both for commercial stocks and species of conservation concern. Within European waters, the landing obligations that are currently being phased in as part of the European Union's reformed common fisheries policy means that an increasing number of fish stocks, with certain exceptions, should not be discarded unless it can be demonstrated that there is a high probability of survival. This study reviews the various approaches that have been used to examine the discard survival of elasmobranchs, both in terms of at-vessel mortality (AVM) and post-release mortality (PRM), with relevant findings summarized for both the main types of fishing gear used and by taxonomic group. Discard... |

| Bycatch in fisheries can have profound effects on the abundance of species with relatively low resilience to increased mortality, can alter the evolutionary characteristics and concomitant fitness of affected populations through heritable trait-based selective removals, and can alter ecosystem functions, structure and services through food web trophic links. We challenge current piecemeal bycatch management paradigms, which reduce the mortality of one taxon of conservation concern at the unintended expense of others. Bycatch mitigation measures may also reduce intraspecific genetic diversity. We drew examples of broadly prescribed ‘best practice’ methods to mitigate bycatch that result in unintended cross-taxa conflicts from pelagic longline, tuna purse... |

| Commercial longline fishing data were analyzed and experiments were conducted with gear equipped with hook timers and time-depth recorders in the Reunion Island fishery (21 degrees 5'S lat., 53 degrees 28'E long.) to elucidate direct and indirect effects of the lunar cycle and other operational factors that affect catch rates, catch composition, fish behavior, capture time, and fish survival. Logbook data from 1998 through 2000, comprising 2009 sets, indicated that swordfish (Xiphias gladius) catch-per unit of effort (CPUE) increased during the first and last quarter of the lunar phase, whereas albacore (Thunnus alalunga) CPUE was highest during the full moon. Swordfish were caught rapidly after the longline was set and, like bigeye tuna (Thunnus obesus),... |

| This report describes the June, 2019 ICCAT workshop on swordfish biology studies for growth, reproduction and genetics, hosted by the Instituto Português do Mar e da Atmosfera, Olhão, Portugal . The major objectives of the workshop were to 1) refine sampling and biological data collection protocols, 2) develop protocols and start the sample processing and analysis, and 3) plan for the project future steps. The biological sampling program was established by ICCAT’s Swordfish Species Group in 2018, aiming to improve knowledge of the stock distribution, age and gender of the catch, growth rate, age at maturation, maturation rate, spawning season and location and diet. This work will contribute to the next major advance in the assessment of swordfish status,... |

| More than ten years after its launching, an evaluation of the results of the FADs programme carried on in Reunion Island has been made. Its implementation and its impact on artisanal fishery in Reunion Island have been analysed. This analysis demonstrates that, following a continuously ascending phase, the production of fish caught on fads has reached a plateau. Parallel to the FAD-associated fishery, the longline fishery has developed since 1991. This type of fishery includes production units whose operating zone is bordering the FAD installation area. Analysing the evolution of the small longliner sector is based on general activity indicators (number of ships, production, fish selling prices). Besides, a synthesis of the interactions between those two... |

| Contrary to the situation in Europe, Réunion Island is the only French department whose fishing has increased considerably for five years, as far as artisanal fishing linked to DCPs (Fish Concentration Plans), but also semi-industrial longline fishing and industrial fishing in southern oceans are concerned. Two capital events contribute to the quick development of tuna fishing and provide Reunion Island with access to its pelagic resources. The setting up in 1988 of the first DCPs by the French Research institute for the exploitation of the sea (Ifremer) resulted in a real upheaval of artisanal fishery and relaunched a sector which had been slowing down since 1980. In 1991, witnessing the success of Asian longline boats unloading on Reunion Island, a local... |

| The Mediterranean Large Elasmobranchs Monitoring (MEDLEM) database contains over 3000 records (more than 4000 individuals) of large elasmobranch species from 20 different countries around the Mediterranean and Black seas, observed from 1666 to 2017. The main species included in the archive are the devil fish (1 813 individuals), the basking shark (939 individuals), the blue shark (585 individuals) and the great white shark (337 individuals). In the last decades other species such as the shortfin mako (166 individuals), the spiny butterfly ray (138) and the thresher shark (174 individuals) were reported with an increasing frequency. This was possibly due to an increased public awareness on the conservation status of sharks, and a consequent development of... |
