Sec. 529.1150 Hydrogen peroxide

Specifications. Each milliliter of solution contains 396.1 milligrams (mg) hydrogen peroxide (a 35% w/w solution).

Conditions of use

Freshwater-reared finfish eggs

Amount

500 to 1,000 mg per liter (/L) of culture water for 15 minutes in a continuous flow system once per day on consecutive or alternate days until hatch for all coldwater and coolwater species of freshwater-reared finfish eggs or 750 to 1,000 mg/L for 15 minutes in a continuous flow system once per day on consecutive or alternate days until hatch for all warmwater species of freshwater-reared finfish eggs.

Indications

Control mortality in freshwater-reared finfish eggs due to saprolegniasis.

Limitations

Initial bioassay on a small number is recommended before treating the entire group. Eggs: Some strains of rainbow trout eggs are sensitive to hydrogen peroxide treatment at a time during incubation concurrent with blastopore formation through closure, about 70 to 140 Daily Temperature Units, [deg]C. Consider withholding treatment or using an alternate therapeutant during that sensitive time to reduce egg mortalities due to drug toxicity.

Freshwater-reared salmonids

100 mg/L for 30 minutes or 50 to 100 mg/L for 60 minutes once per day on alternate days for three treatments in a continuous flow water supply or as a static bath.

Indications for use.

Control mortality in freshwater-reared salmonids due to bacterial gill disease associated with Flavobacterium branchiophilum.

Limitations

Initial bioassay on a small number is recommended before treating the entire group.

Fingerlings and adults of coolwater species of freshwater-reared finfish (except northern pike & paddlefish) and channel catfish

Amount

50 to 75 mg/L for 60 minutes once per day on alternate days for three treatments in continuous flow water supply or as a static bath. Coolwater species of freshwater-reared finfish fry (except northern pike, pallid sturgeon & paddlefish) and channel catfish fry: 50 mg/L for 60 minutes once per day on alternate days for three treatments in continuous flow water supply or as a static bath.

Indications

Control mortality in freshwater-reared coolwater finfish and channel catfish due to external columnaris disease associated with Flavobacterium columnare (Flexibacter columnaris)

Limitations

Initial bioassay on a small number is recommended before treating the entire group. Use with caution on walleye.
