Summary

The article deals with the use an approved aquaculture sanitizer: sodium-percarbonate (SPC).The substance is an easy to use powder containing hydrogen peroxide; when added to fish ponds hydrogen peroxide gets dissolved and subsequently decomposed into oxygen and water. This article presents the results from measurements in January 2017 in connection with practical application at an organic fish. The study showed that SPC leads to an evenly distribution of hydrogen peroxide in the water and maintained for a few hours. The water treatment causes oxygen liberation at the same time but also a significant pH increase which has to be taken into account for optimal management.

Summary translation

Artiklen omhandler brugen af det godkendte akvakultur hjælpestof natriumpercarbonat.
Stoffet er et brintoverilteholdigt pulver der er let at anvende og har vandrensende effekt; når det tilsættes kummer eller damme opløses brintoverilten som efterfølgende nedbrydes til ilt og vand. I artiklen præsenteres resultater fra målinger i januar 2017 i forbindelse med praktisk anvendelse af stoffet på et økologisk fiskeopdræt. Undersøgelserne viste, at stoffet giver en god fordeling af brintoverilte i vandet der opretholdes i et par timer. Vandbehandlingen medførte udvikling af ilt men også en samtidig betydelig pH stigning som der skal tages særligt hensyn.
