Result of electric peaches

The tables show the number of fish by species and by operation, on a given station, observed from electric fisheries. A stand of fish is the result of many factors, intervening at various scales of space and time. In addition to the information on the presence or absence of a particular species, the analysis of the results of the various samples makes it possible to approach the qualification of the aquatic environment. Fish is an integrative organism of environmental conditions, i.e. stands are able to withstand when environmental conditions become less favourable, and apart from acute mortalities, there are not necessarily large immediate changes in stand. On the other hand, if the aggression is serious (e.g. acute pollution) or if environmental conditions change permanently, the settlement will change, in the first case by the brutal disappearance of certain species, in the second by the establishment of a new balance of species. Thus, fish observation is a means of assessing the state of the aquatic environment. __Origin__ Data from electric peaches. __Partner organisations__ ONEMA, ONEMA [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/9c909171c9599840af3e94b8ad7bb673d8d3ed97) The tables show the number of fish by species and by operation, on a given station, observed from electric fisheries.
