First Call for abstracts to ICES/FAO WGFTFB23

The International ICES/FAO WG on Fishing Technology and Fish Behaviour (WGFTFB) taking place 13-17 February 2023 (Kochi, India) will be the first physical meeting since 2019, and as such will be an important event for relaunching the groups primary function of exchanging important research findings, innovations and building of dynamic new networks and collaborations.

Call for Abstract(s)

Oral and poster presentations are the main mechanism for the exchange of information.  This mail serves as a first call for abstract submissions. We invite proposals for two types of presentations:
1. Oral Presentations (formal presentations and slides) (*)
2. Poster Presentations

(*) if time slots for presentations are limited, some abstracts for oral presentation may be accepted for poster presentation.

Topic Areas.

There is no limitation to the topic of your abstract – apart from relevance for WGFTFB. Topics could include for example:

– research related to fishing gears

– modelling approaches

– implementation and implications for fisheries management

– behaviour of animals related to the catch process

– new ideas and projects

– technical solutions to help investigations

– technical issues that need addressing

Proposal Submission

Interested presenters should submit an abstract using the form:, summarising the proposed presentation and indicating to which (if any) Topic Group the abstract relates to. Submissions will be judged on relevance to the working group themes, clarity of thought, data/documented results, fit within the meeting program and other criteria.

NOTE: The deadline for abstract submission is 12th December 2022.

Meeting Registration

All presenters are required to register online at:

Registration is free of charge for WGFTFB members (Regular and Chair-invited members).

Underwater footages in bottom trawling

I am involved in a project focused on understanding, through underwater footage in bottom trawling, the efficacy of selection grids and gaining basic information on the behaviour of fish/shrimps towards them. Hauls will be performed at depths ranging from 100 to 200 m.

In my institute, we have always worked with GoPros and deepwater housings associated with lights (see the images attached), but sometimes, especially in dark and/or high turbidity environment, the footages are not usable.

Do you have any alternative or advice on the best solution to obtain useful footages during trawl hauls to monitor escapees from selection devices and some behaviour information?

We use these devices on commercial vessels, so we need easy-handling equipment.
Best regards,

Potential producer for MiniSeine system

Several of you know about the work on the MiniSeine as potential alternative gear for some gillnet fisheries in areas with high seal depredation rates on gillnets like the Baltic Sea.

Some work on the gear is ongoing in Sweden (SLU), some work has been done in Denmark (DTU), and the first trials in German waters (Thünen; finished some weeks ago.

Although the catches in the German trials were rather promising, several major issues with the gear (e.g., slow retrieval speed due to weak drum engines) could be identified. Therefore, we are considering/planning to procure a more professional system and would like to make use of our “swarm intelligence” to find out if anyone can recommend any company being able to provide us with such gear.

Besides Kynde & Toft in Denmark (, whose service catalogue covers mainly larger systems, I am in touch with Lorentzen Hydraulikk in Norway (, who offer more or less exactly what we need:

Anyway, I would like to know if you have experience, suggestions, or ideas for other companies that could produce or even offer such gear.

Offshore wind installations for electrical generation

Request for Expressions of Interest

More and more countries are developing offshore wind installations for electrical generation. Some already have installed large numbers of turbines. The existing and proposed installations often overlap with existing commercial fisheries. In some regions, the fishing industry has expressed concern that fishing will be completely displaced due to several concerns, primarily involving safety and mobile gears. The installations will also interfere with the monitoring of fish resources by impairing trawl-based resource surveys.

Mike Pol is interested in a closer examination of several topics related to the accessibility of wind farms for commercial fishing and for surveys. His interest was spurred because he was asked to create scaled drawings of mobile gears within a wind farm (see an example in Figure 1), and he was surprised at the relative size of the gear, as well as a lack of relevant literature.

He thinks would be interesting to:

  • Investigate potential for the safe operation of otter trawls within a wind farm based on improved knowledge and modelling of movement and behaviour of doors, nets, and cables.
  • Investigate potential adjustments to design parameters of wind installations (particularly floating turbines) to improve accessibility to fishing
  • Investigate current adaptations by commercial fleets and stock surveys to installed wind farms
  • Understand the potential for the development of alternative exploitation methods
  • Understand the potential for the development of alternative survey approaches.

At an informal discussion after the Annual Meeting of WGFTFB recently, Mike Pol was pleasantly surprised to find several of the WG members are similarly interested. It was suggested a blog post on the WGFTFB website would be a good way to inspire a discussion that could lead to a topic group or similar effort.

He would be interested in any and all feedback.
