Resumo: | IFREMER aims at digitalizing trawl gear in order to reach two goals: on the one hand, participating in the realisation of a computer assisted trawl conception software; on the other hand, being able to study quickly and easily the influence of different adjustment parameters on the shape of the trawl in order to indicate to the skipper, if possible in real time, the optimal adjustment for the conditions he's in. From an international point of view, there are only two strategies to approach this problem: - the first strategy is based on statistical studies on the existing nets (almost limited to their reproduction on different scales), but this approach does not leave much room for innovation as it can only be applied to the same type of nets as those that have been tried before. - the second strategy consists of an "assemblage" of different parts that have been tried separately. Trials are realised with rectangular net panels or net frustums, rigidified with plaster or through artificial tensions. There is no similarity law and, consequently, no generalization of the results. The solution we propose is a digital model, based on an original and more general approach of the problem.
