Autores: Masse, Jacques; Mehault, Sonia; Beillois, Pierre; Duhamel, Erwan; Planque, Benjamin; Petitgas, Pierre; Biseau, Alain.
An acoustic survey was carried out in the bay of Biscay from May 1st to May 30th  on board the French research vessel Thalassa. The objective of PELGAS06 survey was to study the abundance and distribution of pelagic fish in the Bay of Biscay. The target species were mainly anchovy and sardine and were considered in a multi-specific context. The results have to be used during ICES working groups in charge of the assessment of sardine, anchovy, mackerel and horse mackerel and in the frame of the Ifremer fisheries ecology program "resources variability"

What can be expected of a T90 extension piece to improve selectivity in bottom trawl multispecific fisheries in the Bay of Biscay?
Provedor de dados: 5
Autores: Kopp, Dorothee; Morandeau, Fabien; Mouchet, Maud; Vogel, Camille; Mehault, Sonia.
In the Bay of Biscay, the selective properties of otter trawls have mainly been studied with regard to single species. However, for bottom trawl multispecific fisheries targeting fish, it remains challenging to find a selective device capable of limiting catches of small individuals of several species without commercial losses. The present study focuses on an innovative technical solution to reduce catches of undersized individuals in a multispecies bottom trawl fishery in the Bay of Biscay. We tested a cylinder made of 100-mm diamond meshes turned at 90°, namely T90 inserted in the extension piece. We present the selectivity results obtained for six commercial species. This device allows the escape of small Solea solea, Trachurus trachurus and...

Survival of European plaice discarded from coastal otter trawl fisheries in the English Channel
Provedor de dados: 5
Autores: Morfin, Marie; Kopp, Dorothee; Benoit, Hugues P.; Mehault, Sonia; Randall, Peter; Foster, Robert; Catchpole, Thomas.
Species that have a high likelihood of surviving the discarding process have become great concern since the European Union reformed the Common Fisheries Policy and enacted a landing obligation prohibiting the discarding any individuals of species under quota. Among species presenting an elevated survival potential, plaice (Pleuronectes platessa) is one of the most discarded in the coastal otter trawl fishery in the English Channel. The objective of this study is to provide the most reliable estimates of plaice survival after release in commercial conditions, and to identify the factors that influence survival rates. A captivity experiment was conducted in January–February in the English fishery to assess the survival of discarded plaice as a function of a...

Impact of egg production and stock structure on MSY reference points and its management implications for southern hake (Merluccius merluccius)
Provedor de dados: 5
Autores: Cervino, Santiago; Dominguez-petit, Rosario; Jardim, Ernesto; Mehault, Sonia; Pineiro, Carmen; Saborido-rey, Fran.
Spawning stock biomass (SSB) is one of the most common measures of stock status. However recent research on reproductive potential has shown that alternative variables may be an improvement over SSB. In the case of European hake (Merluccius merluccius), it is known that large individuals produce more eggs by unit of body weight, and their quality is better than those of small individuals. Under these circumstances, application of reproductive potential may be pertinent in the implementation of the Johannesburg agreement, since it is not only the spawning biomass but also its age or length structure that defines stock productivity and its ability to achieve maximum sustainable yield (MSY). In this contribution we used an age-length structured population...

Essais de dispositifs sélectifs par les flottilles chalutières du golfe de Gascogne. Programme REDRESSE
Provedor de dados: 5
Autores: Mehault, Sonia; Larnaud, Pascal; Rimaud, Thomas; Cuillandre, Jean-pierre; Morandeau, Fabien; Simon, Julien; Vacherot, Jean-philippe.
The landing obligation implemented under the Common Fisheries Policy promoted the development of fishing gear selective devices. The REDRESSE project conducted in the Bay of Biscay was the opportunity for trawl fleets targeting cephalopods, Nephrops and demersal fish to continue to test various selective configurations to reduce their discards levels. The sea trials were carried out onboard of commercial fishing vessels and the experimental tows were sampled by an observer. Most of the selective devices were tested under the twin trawl method, with on one side the gear to be tested and on the other, the standard commercial gear. Other devices were tested with the parallel or alternate haul method. The data obtained were used to describe the catch species...

Survie des rejets de langoustine après chalutage.
Provedor de dados: 5
Autores: Mehault, Sonia; Morandeau, Fabien; Kopp, Dorothee.
Le taux de survie des langoustines rejetées après chalutage est estimé aujourd’hui à 51% contre 30% dans les années 70-80. Cette valeur estimée expérimentalement est donc un majorant du taux de survie réel qui est impacté par de nombreux facteurs difficilement quantifiables. La mortalité des rejets peut être réduite par l’utilisation de table de tri et de goulotte d’évacuation lors du traitement de la capture. Cependant, la survie des langoustines au-delà du moment de leur remise à l’eau est difficile à évaluer, mais il est certain que leurs chances de survie sont réduites si elles sont rejetées en dehors des secteurs où les individus pourront retrouver un habitat qui leur est favorable.

Survival of discarded Nephrops norvegicus after trawling in the Bay of Biscay
Provedor de dados: 5
Autores: Mehault, Sonia; Morandeau, Fabien; Kopp, Dorothee.
The new Common Fisheries Policy may exempt some species from the landing obligation if a high survival rate can be demonstrated among discards. This study focuses on the survival capacity of Nephrops norvegicus discarded from trawlers of the Bay of Biscay (France). Three sea trials were conducted on board 3 commercial trawlers and 15 fishing operations were sampled. The vitality of Nephrops was classed into three categories (healthy, moribund or dead) before release at sea and samples of healthy and moribund individuals were kept in captivity on Nephrops grounds for three days. A Generalised Linear Model was used to examine the variability in the proportion of healthy Nephrops discarded, which was significantly influenced by tow duration, duration of air...

Some expected impacts of the Common Fishery Policy on marine food webs
Provedor de dados: 5
Autores: Kopp, Dorothee; Robert, Marianne; Chouvelon, Tiphaine; Mehault, Sonia.
For the ecosystem approach to fisheries management, understanding population dynamics and ecosystem resilience in response to the landing obligation acted by the reform of the European Common Fishery Policy (CFP) is currently an important avenue of research. This study attempts to assess the impact of the new CFP on marine food webs. Total carbon and nitrogen loss induced by a discard ban were estimated for the ecosystem of the Bay of Biscay based on French At-Sea Observer data and carbon and nitrogen content of discarded fish. Changes in predator diets were estimated by comparing two Bayesian mixing models, one mimicking the current situation and the second the application of the new CFP (removing the discarded species that would be landed from the...

Survivability of discarded Norway lobster in the bottom trawl fishery of the Bay of Biscay
Provedor de dados: 5
Autores: Merillet, Laurene; Mehault, Sonia; Rimaud, Thomas; Piton, Corentine; Morandeau, Fabien; Morfin, Marie; Kopp, Dorothee.
In the context of the landing obligation set by the new Common Fisheries Policy (CFP), Norway lobster Nephrops norvegicus was identified as a species likely to have high survival rate when discarded in the bottom trawl fishery of the Bay of Biscay. Previous studies in this area reported a survival rate between 30% and 51%, but the experiments were done on a limited monitoring period and the seasonal variations were not investigated. This study was designed to obtain a reliable value for survival rate after a 14-day monitoring period in onshore tanks allowing considering delayed mortality. The study also tested the effect on the survival rate of using a discarding chute system, a sorting device that was made mandatory on the 1st of January 2017 for Nephrops...

Are trawl marks a good indicator of trawling pressure in muddy sand fishing grounds?
Provedor de dados: 5
Autores: Merillet, Laurene; Kopp, Dorothee; Robert, Marianne; Salaun, Michele; Mehault, Sonia; Bourillet, Jean-francois; Mouchet, Maud.
The development of the vessel monitoring system (VMS) in the recent years has offered high-resolution data to map the distribution and intensity of fishing activities and contributed to enhancing the potential identification of fishing impacts. However, impacts could vary at very small scale and the resolution of VMS data might not be fine enough. Other proxy could be used, such as trawl marks visible on the seabed observed by underwater video or side-scan sonar to evaluate small-scale trawling effort. In the Bay of Biscay, an underwater video survey of the Nephrops norvegicus fishing ground was conducted and provided environmental characteristics such as depth and number of trawl marks at 152 transects. The relevance of observed trawl marks as a...

From discard ban to exemption: How can gear technology help reduce catches of undersized Nephrops and hake in the Bay of Biscay trawling fleet?
Provedor de dados: 5
Autores: Vogel, Camille; Kopp, Dorothee; Mehault, Sonia.
On January 1st, 2016, the French mixed Nephrops and hake fishery of the Grande Vasière, an area located in the Bay of Biscay, fell under the discard ban implemented as part of the new European Common Fisheries Policy. The fleet records historically high levels of discard despite numerous gear selectivity studies. Together with high discards survival, new technological solutions to minimize catches of undersized individuals could justify local exemptions from the discard ban. Our study focuses on the effects of two selective devices, a square mesh cylinder (SMC) and a grid, on the escapement of undersized individuals and discard reduction. Relative catch probability of the modified gear compared with the traditional gear was modelled using the catch...

Improving gear selectivity of whiting ( Merlangius merlangus ) on board French demersal trawlers in the English Channel and North Sea
Provedor de dados: 5
Autores: Vogel, Camille; Kopp, Dorothee; Morandeau, Fabien; Morfin, Marie; Mehault, Sonia.
In the English Channel and Southern Bight, French demersal trawlers target a mix of demersal species including whiting (Merlangius merlangus). The discard ban to be implemented in January 2016 motivated fishermen to look for technical measures to reduce unwanted catches of undersized individuals (&lt;27 cm). From 2008–2014, 18 different gear configurations were tested for bycatch reduction on board fleets of vessels of 16–20 m and 20–24 m. Selective devices tested included grids, square mesh panels (SMP), square mesh cylinders (SMC), various combinations of these devices and large mesh trawls. Using the catch comparison method, our results focus on six devices that proved efficient to reduce catches of undersized whiting, equally divided between the two...

Narrowing down the number of species requiring detailed study as candidates for the EU Common Fisheries Policy discard ban
Provedor de dados: 5
Autores: Morfin, Marie; Mehault, Sonia; Benoit, Hugues P.; Kopp, Dorothee.
By 2019, the Common Fisheries Policy will prohibit discarding in all European fisheries of any pelagic, demersal or shellfish species for which removals are managed by TACs and quotas or minimum sizes. However, the regulation allows for exemptions from the prohibition for species for which scientific evidence demonstrates high survival rates associated with discarding. Producing reliable evidence of high survival typically requires long and costly studies involving tagging or captivity. This paper proposes to use the capacity to resist air exposure, a key stressor for discarded animals, as a proxy for survival that can be used to prioritize candidate species for more in-depth discard survival studies. The time required to induce mortality (TM) in...

A bio-economic analysis of experimental selective devices in the Norway lobster (Nephrops norvegicus) fishery in the Bay of Biscay
Provedor de dados: 5
Autores: Raveau, Adriana; Macher, Claire; Mehault, Sonia; Merzereaud, Mathieu; Le Grand, Christelle; Guyader, Olivier; Bertignac, Michel; Fifas, Spyros; Guillen Garcia, Jordi.
Several fleets with various fishing strategies operate as a mixed fishery in the Bay of Biscay. Among the main fleets, bottom trawlers target Norway lobster (Nephrops norvegicus) and, together with gillnetters, they also catch hake (Merluccius merluccius). Trawling leads to average-size catches that are below the minimum landing size (MLS); such catches are discarded since they cannot be sold. These discards result in negative impacts on stock renewal, as most of them do not survive. This also results in an economic loss for both bottom trawlers and gillnetters since these discards represent a future loss of rent. This study, based on the 2009 and 2010 selectivity experiments at sea, assesses the short- and long-term bio-economic impacts of four...

Baltic Sea Benthic ecosystem impacts from demersal fishery in the western Baltic is assumed to come mainly from Nephrops trawling in the central and southern Kattegat, mussel dredging in the Belt Sea, and mixed cod trawling in the western Baltic Sea.These fisheries both impact the seabed, as well as produce substantial amounts of discards. The western Baltic Sea offer a unique opportunity to analyse the benthic effects of fishingthanks to the closure of Øresund to towed gears since the 1920s, and the introduction of the Kattegat MPA in2009 (including cod closure) and the western Baltic Sea Natura-2000 areas. Furthermore an extensive benthic nationalmonitoring and data collection effort has taken place in the area over a number of years, which can be usedto...

In the context of the reform of the Common Fishing Policy (CFP) undertaken by the European Union and implemented since 1st January 2014, the discarding of unwanted catches will gradually be forbidden. Article 15 of the CFP lays down a landing obligation for all species subject to European quotas and will come into force between 2015 and 2019 according to the species and the zones. The Regulation allows several exemptions including one for "species for which scientific proof shows high survival rates, due to the characteristics of the fishing gear, the fishing methods and the ecosystem" (EU Regulation No. 1380/2013). In particular, Nephrops were identified by the International Council for the Exploration of the Sea (ICES) as one of the species having the...
