Recently a short-term EU-project has been started to make a feasibility study on
the set-up and maintenance of a fishing gear selectivity database. Co-operating
countries are Belgium, Denmark, Finland, France, Germany, Greece, the
Netherlands, Norway, Portugal, Spain, Sweden, the UK and ICES (co-ordination by
The basic idea is that it is a pity that high amounts of selectivity data exist,
in offices under a layer of dust, which will never see the daylight again. These
data are of interest to many people dealing with fisheries. But before any
effort (and finances) is put into setting up a database, we need as much
information as possible on interested people and institutes, i.e. users and data
providers. We also would like to know about the degree of detail is requested
(raw data or results) and the type of database (central or not, available
through WWW etc., only Europe or unrestricted). Therefore a questionnaire has
been made to be distributed and for which we hope to get a high response.
We are convinced that initiatives like this one can be beneficial to the
management of fisheries and we hope that the outcome of the project will be
positive so that the effort you put in responding to us has not been a waste of
time. It is my intention to provide everyone who replied with an outline about
the outcome of the project (early 1998).
The questionnaire is part of this message. If you are interested you can fill it
out and e-mail it back to me ([log in to unmask]) or send a printout to "Hans
Polet, Grintweg 47, B-8400 Oostende, Belgium" (an answer sheet with the question
numbers + answers is OK as well). If you don't like questionnaires any comments
