CAUTION – Hydrogen Peroxide H2O2 for livewell oxygenation can damage fish gills
A continuous safe supply of dissolved oxygen at delivered at 100% DO saturation continuously and the right dose of non-iodized salt trumps mechanical aeration, livewell pumps and livewell chemicals used in boat livewells and bait tanks. For freshwater tournament fish and live bait fish, non-iodized salt supplementation aids in reducing the work of osmoregulation improving fish health during transport. Saltwater specie transported in saltwater livewells do not need supplemental salt or additives containing salt. Saltwater contains plenty of salt. Salt is an electrolyte. Providing the best livewell water quality for tournament fish care and live bait care is always the fisherman’s choice.
Providing enough dissolved oxygen for large livewell stocking densities is the most important livewell water parameter in any livewell or bait tank when keeping fish alive and healthy during transport. Overcrowded livewell require more dissolved oxygen than livewells with normal stocking densities. There are numerous oxygen delivery systems available for sport fishermen and commercial fishermen that will insure continuous optimal safe dissolved oxygen saturations for overstocked livewells and bait tanks.
Hydrogen Peroxide (H2O2) livewell supplementation is often recommended in bass tournament world as a cheap, cost effective livewell chemical that will insure safe livewell oxygenation all day for a large limit of bass on a hot summer tournament day in June/July.
Hydrogen Peroxide H2O2 – the fishery science and scientific facts about using this chemical to insure minimal sale livewell oxygenation is diametrically opposed to U-tube promos touted by bass tournament pros, promotional bass fisherman testimonials, recommendations by bass tournament organizers and advertisement promoted by many livewell chemical companies.

There is no livewell chemical in the world that trumps a continuous supply of pure compressed oxygen delivered in a sufficient doses, volume and concentration delivered and dissolved into a hot a summer livewell full of fish or live bait during transport.

The Use of Hydrogen Peroxide in Fin Fish Aquaculture by Roy P.E. Yanong
Hydrogen peroxide is commonly used as a disinfectant for cleaning wounds in people. Hydrogen peroxide has also been used in aquaculture as an immersion (bath) treatment against many different disease-causing organisms, including external parasites, bacteria, and fungi, on different species and life-stages of fish. The U.S. Food and Drug Administration (FDA) recently approved a hydrogen-peroxide-based aquaculture product, which has spurred greater interest in its use.
Is hydrogen peroxide legal for use in aquaculture? In 2007, 35% PEROX-AID® (Eka Chemicals, Marietta, Georgia) was approved by the FDA for control of mortality in (1) freshwater-reared finfish eggs due to saprolegniasis (a common water mold), (2) freshwater-reared salmonids due to bacterial gill disease (Flavobacterium branchiophilum), and (3) freshwater-reared coolwater finfish and channel catfish due to external columnaris (Flavobacterium columnare) disease. No other forms of hydrogen peroxide, including those sold for human use, are approved for use with fish.
Can hydrogen peroxide be used on other warmwater finfish species intended for human consumption and for other indications not on the label?
A veterinarian can prescribe 35% PEROX-AID® for an extralabel use provided that all the provisions in Title 21 Code of Federal Regulations Part 530 (21 CFR 530) http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?CFRPart=530 are followed. In brief, the client must be working with a veterinarian within the context of a valid veterinarian-client-patient relationship (see description below), and there must be no residues that pose a public health risk. Research using food fish species is much more common in the literature, and biotests will most likely be required to determine the best dose and treatment time for specific disease problems. A summary of unapproved doses and indications used by researchers in foodfish species is outlined in Table 2. As for approved uses and species, follow label instructions and contact the appropriate regulatory authorities regarding discharge of treated water.
21 CFR 530:
A valid veterinarian-client-patient relationship is one in which:
(1) A veterinarian has assumed the responsibility for making medical judgments regarding the health of (an) animal(s) and the need for medical treatment, and the client (the owner of the animal or animals or other caretaker) has agreed to follow the instructions of the veterinarian;
(2) There is sufficient knowledge of the animal(s) by the veterinarian to initiate at least a general or preliminary diagnosis of the medical condition of the animal(s); and
(3) The practicing veterinarian is readily available for follow-up in case of adverse reactions or failure of the regimen of therapy. Such a relationship can exist only when the veterinarian has recently seen and is personally acquainted with the keeping and care of the animal(s) by virtue of examination of the animal(s) and/or by medically appropriate and timely visits to the premises where the animal(s) are kept. http://edis.ifas.ufl.edu/fa157

[LIVEWELL] CHEMICALS – pg 21
Another chemical that has sometimes been used to treat livewell or holding tank water is Hydrogen Peroxide (H2O2). Hydrogen Peroxide breaks down into oxygen and water in the presence of organic matter. However, this chemical can injure fish and should not be used. Most people have used this colorless, odorless, tasteless liquid to disinfect a cut or scratch. You can see it fizzing and bubbling on the skin as it oxidizes. Now imagine what it does in a livewell full of bass. The bass’ mucus coating protects its skin from the oxidation reaction, but there is no such protective coating on the delicate gill filaments. Unfortunately, anglers that use Hydrogen Peroxide think that is a little is good, a little more should be better. Wrong! Damage to gill filaments, suffocation, and death may result.
DO NOT USE HYDROGEN PEROXIDE IN THE LIVEWELL
