Workshop to promote Norway-Spain cooperation in the fisheries research field
Vigo, May 20th– 21st of 2014
The cooperation between the Fisheries Ecology Group from the Institute of Marine Research (IIM-CSIC, Spain), the Oceanographic Center of Vigo and A Coruña from the Spanish Institute of Oceanography (IEO, Spain) and the Demersal Fish Group from the Institute of Marine Research (IMR, Norway) in the field of the biology and ecology of demersal exploited fish started many years ago and was materialized in several European projects (REDFISH, RASER, BECAUSE, FINE, EFIMAS, FRESH), working groups (WG NAFO on Fish Reproductive Potential, ICES WG and WS) and cooperation for pre and postdoctoral researchers training. These three institutions are fisheries research models in their respective countries and share common interest around different scientific topics. The present workshop focused on the identification of synergies between IMR, IIM-CSIC and IEO to promote stable cooperation research lines that lead not only to development of project proposals, but also, to the exchange of researchers and technician to share knowledge and experience in different fields of fisheries research.
During these years of cooperation, three main topics of interest have been identified:
- Standarization and validation of ageing methods in demersal species: The three institutions count on experts on otolith reading and fish ageing. Currently, there are some species in which ageing methods are under debate, for example Atlantic cod or European hake. Standarization of ageing protocols, exchange exercises as well as group analysis and discussion would be very interesting to solve these questions.
- Reproductive and spatial ecology of demersal species: The three institutions have broad experience in fish reproductive ecology and more recently in spatial ecology. Sharing knowledge and experience of these research groups could shed light on demersal ecosystem functioning to determine the “key-factors” are affecting stocks dynamic.
- Ecosystem approach to fisheries assessment and management: The three institutions have experts on fisheries assessment with experience on ecosystem modelling. Knowledge exchange and comparative studies could lead to develop new ecosystems models or improve the existents to be applied in fisheries assessment.
Besides these three hot topics, there is a fourth new cooperation field. Maximum abundances of European hake have been recently recorded in Norwegian waters, both in fjords and coastal waters. The biology and ecology of this species in its Northern limit of distribution has been barely studied, however, the increasing abundance as well as its inclusion in the list of Norwegian commercial species urge to investigate Norwegian hake ecology for an adequate management and preservation. In this framework, the long experience of the Fisheries Ecology Groups from the IIM-CSIC on reproductive ecology of European hake, and the expertise of the O.C. of Vigo from the IEO on hake growth, could be helpful for IMR researchers to increase the knowledge about Norwegian stock of European hake.
This workshop was born around these topics and its main objective was to promote new links and strengthen the existing ones between the IMR, the IIM-CSIC and the IEO in the field of fisheries research. The chairmen of the workshop were Rosario Dominguez-Petit from the IIM-CSIC and Olav S. Kjesbu from the IMR.
The first day was in plenum. The day was divided into three sessions concerning modelling, recruitment and otoliths. Each institute had two presentations in each session to show a broad perspective of the work done on the different subjects.
The second day started with a plenum with an introduction to the work done on hake and ballan wrasse at each institute. Afterwards, two parallel sessions took place: one session for scientific discussion about potential research cooperation and another technical session on ageing and otolith reading.
