Aquacen Formaldehyde

FORMALDEHYDE

QUALITATIVE AND QUANTITATIVE COMPOSITION

Active substance:
Formaldehyde 380 mg
Excipients, c.s.p. 1 ml

Indications

Fish: Sea bream , Turbot. Control of external parasitosis of Microcotilae spp. and Philasterides dicentrarchi. At the recommended dose and posology, the mortality of infested animals is reduced, but the infestation is not completely eliminated. The treatment is not effective once the parasite has penetrated inside the fish.

Contra-indications

Do not apply the medicinal product in water at a temperature of more than 27ºC or when there are large concentrations of phytoplankton or when the oxygen concentration is less than 5 mg/litre, as the product may kill the phytoplankton and cause a depletion of dissolved oxygen. If oxygen depletion occurs, new well-aerated water should be added to dilute the solution and provide oxygen.

Do not use the medicinal product if it has been subject to temperatures below 5ºC or freezing, as cold causes the formation of paraformaldehyde which is a toxic substance for fish. Paraformaldehyde can be recognized as it is seen as a white precipitate at the bottom or on the walls of the container.

Withdrawal period

Fish (Sea bream , Turbot): Meat, Zero degree-days.

Special warnings

Special warnings for each target species 
Fish with very high levels of parasite infection or sick fish may present a lower tolerance to treatment. Tolerance to formaldehyde may vary with different batches or species of fish. Whenever possible, testing on a small number of fish is recommended to detect any case of sensitivity before applying the medicinal product.

Special precautions for use in animals
Fish with very high levels of parasite infection or sick fish may present a lower tolerance to treatment. The fish should be observed during treatment in case signs of stress appear, in which case the treated water should be discarded and replaced with non-treated and well-oxygenated water.

Overdose
Do not exceed the recommended dose or application time.
In the event of overdose or if the fish show signs of stress, the treated water should be discarded and replaced with non-treated and well-oxygenated water.
