Cependant, l'étang a aussi un effet favorable en constituant une réserve d'eau. Il se présente souvent comme un régulateur de débit et de niveau de base et peut retenir des matières en suspension et des composés azotés provenant des bassins versants. Dans le cas d'une pisciculture intensive moderne en étangs créés de novo, il existe une tendance a la réutilisation de l'eau dans la pisciculture elle même, sans rejet dans la riviere. Les effluents piscicoles sont ainsi recyclés in situ dans l'écosysteme aquatique et n'affectent pas l'environnement, ce qui constitue une originalité par rapport aux autres élevages hors sol. En cas d'intensification très forte en petits bassins, le recyclage des matieres organiques non réalisables dans ces derniers, peuvent en revanche s'effectuer à proximité dans de grands étangs traditionnels qui se trouvent ainsi fertilisés. Les effluents d'élevage hors sol (lisiers, fientes de volailles) sont aussi classiquement recyclés dans des étangs, avec production extensive (grands étangs) ou plus intensive en petits étangs aménagés (acces aux berges, aérateurs). Le recyclage de plus grandes quantités d'effluents d'élevage peut être pratiqué en lagunage compartimenté avec production séparée d' algues et de daphnies. Ces dernières sont soit distribuées vivantes directement aux poissons, soit séchées et incorporées aux aliments pour animaux. La pisciculture en étang, ou associée aux étangs, qui recycle à la fois ses propres effluents et ceux provenant d'élevages hors sol, est donc, sous réserve d'une bonne gestion, une forme d'élevage qui n'apporte pas de perturbations à l'environnement.","AbstractOtherLang":"The negative and positive impacts of pond fish farming on the environment. The culture of fish in ponds may have negative impacts on the environment in particular on the river, upstream and downstream because of fish escapes, and downstream because of the release of slightly degraded water. However, ponds also have a favorable impact, i.e. storing water, regulating the flow rate and the basal level; they may retain suspended solids and nitrogen compounds coming from the watershed. In the case of new intensive production units, the tendency is to reuse the water in the fish farm, without release in the river. Fish manures are then recycled in situ in the aquatic ecosystem with less damage for the environment, compared to other out of soil production units. In case of strong intensification of production in small ponds with limited recycling capacity, water must be recycled in large traditional ponds which become fertilized. Various farm animal manures also are traditionally recycled in ponds with extensive or intensive production. A more sophisticated way for recycling manure is to separate production of algae and Daphnia in different pools. Daphnia can be distributed directly to fish or harvested, treated and incorporated to animal feeds. Fish farming in ponds, or in structures associated to ponds, is able to recycle its own manure and animal manure and represents a rearing form not harmful to the environment.","BibLvlCode":"AMS","StandardTitle":"Les impacts négatifs et positifs de la pisciculture d'étang sur l'environnement","OrigTitleLangCode":"fr","OrigTitleLangCodeExtended":"fre","OrigTitleLangID":22,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1993,"MonPub":null,"DateUpdate":"2019-09-10","DateCreate":"2001-08-02","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":14660,"PubliDate":1993,"Pagination":"17-29","XtraPublOfAnaID":null,"ISBN":null,"Volume":"18","Issue":null,"BRefMon":14655,"BRefMonRR":"Barnabé, G.; Kestemont, P.
