Sustainable fishing, Wednesday 10th of October

 09:00 / 09:15 Introduction

SESSION 1 Detection of organisms and population assessment

09:15 / 09:30 Verena TRENKEL, Ifremer, France
DNA and sustainable exploitation of marine living resources
All living organisms have DNA (deoxyribonucleic acid). It contains the building code for the structure and functioning of organisms. While a large part of the DNA is identical for all organisms, certain DNA sequences are species-specific and others trace the family history. Recent scientific advances in measuring biodiversity and estimating species abundance are making use of these characteristics of DNA. In this talk I will present the state of the art, recent results and potential future applications. The use of DNA for supporting sustainable exploitation offers many opportunities but raises also a number of practical, logistic and technical challenges.
09:30 / 09:45 Jean-Baptiste ROMAGNAN, Ifremer, France
Imaging for the analysis of plankton
The presentation starts with a short movie to introduce the plankton to non-specialists, and show nice images of plankton. The planktonic context in the framework of fish biology will be briefly reminded. Then, imaging for the scientific analysis of plankton will be presented: plankton-specific technical issues to address, instruments and analytic methods and tools. I will briefly explain why imaging is now considered a relevant method to analyze plankton regarding current scientific concerns in the marine ecology field. Finally, I will conclude the presentation by a short discussion on the needs and perspectives of development in the field of imaging for plankton.

The annual survey (since 2014) Langolf-TV aims at estimating the abundance of Nephrops norvegicus in the Bay of Biscay by counting their burrows using a submarine video camera set up on a sled. It replaced the Langolf trawling survey until 2013. Six scientists work 24h/24h to get video footages on the sea floor. These videos are analyzed onboard by accredited observers who then compare their countings of Nephrops burrows.
The results of this survey are used, after processing, in the Bay of Biscay Nephrops stock assessment.
10:00 / 10:15 Laurent BERGER, Ifremer, France
Mapping fish resources using acoustics: a review of latest developments implemented in Ifremer fish stock assessment survey.
Acoustics has been used for several decades by fishermen and fishery scientists for detecting fish schools and estimating abundance at large scale for exploited fish stocks.
The technology has moved from single beam, single frequency to multibeam and broadband acoustics allowing for better identification of species and enabling to detect not only fish but also mapping lower trophic levels and physical environment of the fish.
Based on data acquired during annual stock assessment surveys, illustration on new insights in scattering layer composition of plankton organisms using broadband acoustics will be given, together with seafloor habitat mapping using absolute measurement of seabed backscatter.
10:15 / 10:30 Rolf J KORNELIUSSEN, Institute of Marine Research, Norway
Use of acoustics in Norway for sustainable fishery
Sonars and echosounders are widely used for remote sensing of life in the marine environment. Two challenges of reducing the uncertainty of acoustic abundance estimates are detection of fish close to the surface and species identification. Detection of fish from close to the surface and down in the water column can be done with a high-resolution sonar combined with echosounder data. Species identification can be based on multi-frequency or broadband echosounder data or by optical means. We used data from Simrad MS70 scientific sonar combined with EK80 echosounder data and methods of species identification to reduce uncertainty of abundance estimates.

SESSION 2 Various approaches in fishing gears selectivity

Selective baiting for longlines

Real-time acoustic fishing selectivity for sustainable practices
Preservation of underwater environment with sustainable fishing practices requires accurate ecosystem assessment tool to provide more realistic quantitative and qualitative data.
To reach this goal, iXblue proposes a new generation of “3D MBES” based on steerable symmetrical Mills Cross acoustic array. Configuration of “SeapiX” allows to image water column and sea bottom in both athwart ship and fore-and-aft direction with steering capability, covering 120◦ × 120◦ under ship and describing whole ecosystem.
By combining high spatial “voxel” resolution and large water Colum coverage, statistical processing of new proxy allows to describe the ecosystem in full. It ensures real-time habitat description including seabed classification and biomass species classification.
SeapiX is deployed onboard 60 modern vessels worldwide, and demonstrates daily its capability to provide relevant biomass discrimination for demersal and pelagic fisheries. It enhances dramatically real time biomass resource management and compliance with fishing regulations.
11:45 / 12:00 Pascal Larnaud, Ifremer, France
T90 meshing to improve trawl selectivity
The focus on fishing gear selectivity, mainly on otter trawls, increased with the landing obligation, defined by the European Commission in the CFP 2013. The T90 configuration, when normal mesh is turned through 90 °, tested for the first time in the middle of the 90s, was tested again recently in Europe. The results obtained with two different T90 devices, in Celtic Sea and in the Western Channel, within the CELSELEC and REJEMCELEC projects, will be summarized. The discussion will include a reflection on the implementation of these devices in terms of management.

Improve the innovation performance of the seafood sector
SAFER (Smart Atlantic seaFood clustER) is an european initiative (Interreg Atlantic program) that aims to improve the innovation performance of the seafood sector by increasing technology adoption and transnational cooperation, providing opportunities to introduce new processes, improve efficiency and communication between actors in the seafood value chain.
Launch in november 2017, partners are currently setting up pilot actions in 5 atlantic regions to test the network and its suite of innovation services in real living labs. First results and coming actions will be presented and discussed with SAFER partners and stakeholders.


SESSION 3 Video observation and sensor data acquisition to improve selectivity and for a better knowledge of fishing activities

15:15 / 15:30 Julien SIMON Underwater video techniques to study fish behaviour in fishing gears
Underwater video techniques are becoming more and more used in the field of fisheries research. Indeed, video recordings can provide very helpful information in understanding the behaviour of fish towards fishing gears. Therefore, hundreds of hours are recorded and must be analysed, which is a time-consuming task.
Thus innovative technologies for observing fish do not rely only on the acquisition system but also on post processing system. Considerable advances in computer vision have been made in the last decade. Automated images processing software are new tools that can increase the data analysis capabilities of videos and pictures while reducing the time required to analyse these data.

Data transmission and sustainable fishing
Demonstration of the decisive position of satellite communications in the development of sustainable fishing with the presentation of the OceanBox solution (Monitoring and management tool for ship-to-shore and shore-to-ship satellite data flows) and two examples of solutions associated with fishing data flows:
OceanLive solution: On board video monitoring system allowing the supervision and the recording of fishing operations and in particular bycatch,
ORBIT buoy: Drifting buoy equipped with a high resolution on board sounder allowing the biomass evaluation and species discrimination (PHARE Project).
16:15 / 16:30 Emilie LEBLOND, presented by Loïc QUEMENER, Ifremer, France
The Recopesca project: an example of participative approach to collect fisheries and in-situ environmental data
Face to the lack of data to assess precisely the spatial distribution of catches and fishing effort and for the environmental characterization of the fishing area, Ifremer has implemented the Recopesca project, consisting in fitting out a sample of voluntary fishing vessels with sensors and beacons recording data on fishing effort and physical parameters such as temperature or salinity. For scientific purposes, Recopesca aims to collect data to improve resources assessment and diagnostics on fisheries, and environmental data required for an ecosystem approach to fisheries (EAF) or to feed oceanographic models e.g. for circulation of water masses. It is a concrete achievement of participative approach.
