Lisbon ’07

Reproductive and Recruitment Processes of Exploited         

Marine Fish Stocks

Lisbon, October 1-3

Introduction

The COST Action FA06001 “Fish REproduction and FiSHeries”, FRESH onward, started on June 2007. During the kick-off meeting, the first Management Committee, there was several discussions about the best procedure to initiate the work in each of the three working groups through the preparation of the state of the art reports. The MC agreed that revising the scientific literature together with a large workshop where gathering front research results was the best option. The MC saw the best opportunity allowing FRESH to participate in the local organization of the NAFO-ICES-PICES (Northwest Atlantic Fisheries Organization – International Council for the Exploration of the Sea – North Pacific Marine Science Organization) symposium “Reproductive and Recruitment Processes of Exploited Marine Fish Stocks”. The MC endorsed, thus, this symposium as the first workshop of FRESH.

The workshop was held in Lisbon, at Hotel Altis, during October 1-3. Right after the workshop it was celebrated the second MC and the first meeting of the FRESH Working Group 1 “Identifying the causes and consequences of variation in stock reproductive potential”. A great advantage was the fact of Portugal being member of FRESH, so most of the organization was developed by the FRESH Portuguese delegate, Dr. João Pereira.

Goal

The main goal of the workshop was to provide a scientific forum to present and discuss study findings on reproduction, early life history and recruitment of exploited marine finfish and invertebrate stocks and the implications in stock assessment and fisheries management.

Two objectives were addressed, in one side bringing together FRESH members to continue the discussions, but especially allow FRESH members to gather front research from the international community in order to initiate the work of the Action with a better and clear state of the art in the field of the reproductive ecology and fisheries.

Finally, and not less important, it was considered as a perfect forum to disseminate the goals and expectations of FRESH among the scientific community.

The goals of the workshop were achieved dividing it into four oral sessions:

SESSION 1 – Age and Size at Sexual Maturity

SESSION 2 – Fecundity and Spawning Success

SESSION 3 – Survival of Eggs and Larvae

SESSION 4 – Stock Assessment and Management Implications

This fitted with the three working groups of FRESH:

  • WG 1.- Identifying the causes and consequences of variation in stock reproductive potential.
  • WG 2.- Improving estimates of stock reproductive potential: Standardising sampling procedures and methods across North Atlantic.
  • WG 3.- Linking biology and assessment: Improving stock assessment through implementation of stock reproductive potential.

Also one poster session was held on Monday 1st from 18:00 to 21:00. A reception took place during the poster session along which it was disseminated general information about COST and specific information about FRESH, which included the presentation of a poster and the distribution of brochures.

Participants

A total of 160 registered participants attended to the workshop; from those 25 were FRESH members, which also participated in the Action WG1 held right after the workshop.

FRESH members contributed with 21 oral presentations out of 52, i.e. 40% of the presentations; and 31 out of 90 posters, i.e. 34%.

This reflects very much the importance of FRESH members in the field of reproductive ecology.

Achievements

The attendance to the workshop, both in terms of number of participants, oral and poster contributions, as well the wide variety of studies presented was a complete successful.

The quantity and quality of the contributions exceeded the expectations as reflected in the high number of questions and discussions raised during the workshop but also after each session.

The whole community participating in the workshop agreed that this will be a key workshop and an inflection point in the field of the fisheries management and fish reproduction. FRESH, as an important network dealing with these topics is now the responsible to progress further from this point collecting the information provided in the workshop and designing the lines to be developed in the near future. The chairs of the three FRESH Working Group, all of them participating in the workshop, together with the members of FRESH, have now the sufficient information to advance with the different goals of FRESH.
