“…Adams et al () described histological changes in Atlantic salmon gills following H 2 O 2 treatments including lamellar clubbing, thickening and fusion of lamellar tips, and some epithelial lifting. Similar observations have also been recorded in rainbow trout ( Oncorhynchus mykiss ), where epithelial hyperplasia and lamellar fusion were common in the gills within the first 2 weeks following H 2 O 2 treatment (Speare, Carvajal, & Horney, ). In Atlantic salmon, H 2 O 2 ‐induced gill damage appears to increase with increasing dose rates and treatment temperatures (Kiemer & Black, ).…”

Hydrogen peroxide (H2O2) is a commonly used treatment for a range of parasitic diseases of marine finfish, including amoebic gill disease (AGD). While this treatment is partially effective at reducing parasite load, H2O2 can have detrimental effects on the host under certain conditions. Treatment temperature and dose concentration are two factors that are known to influence the toxicity of H2O2; however, their impact on the outcome of AGD treatment remains unclear. Here, we investigated the effects of treatment temperature (8, 12 or 16°C) and dose concentration (750, 1,000, 1,250 mg/L) on the efficacy of H2O2 to treat AGD. We demonstrated that a 20‐min bath treatment of H2O2 at all doses reduced both parasite load and gross gill score significantly. Parasite load and gross gill score were lowest in the 1,000 mg/L treatment performed at 12°C. At the high dose and temperature combinations, H2O2 caused moderate gill damage and a significant increase in the plasma concentration of electrolytes (sodium, chloride and potassium). Taken together, our study demonstrates that higher H2O2 treatment temperatures can adversely affect the host and do not improve the effectiveness of the treatment.

“…As a result it is generally accepted that hydrogen peroxide use is safest when water temperatures are lower (\13°C). Speare et al (1999) also demonstrated gill lesions in rainbow trout with exposure to hydrogen peroxide at 1,000-1,500 mg/l for 20 min and also at 750 mg/l. The pathology was characterised by foci of epithelial hyperplasia with lamellar fusion, pillar cell necrosis and pillar channel aneurysms.…”

Gill disorders present a significant challenge in salmon (Salmo salar and Oncorhynchus sp.) farming regions throughout the world. This review of gill disorders and diseases of marine fish is focused on the non-infectious causes of gill disease in marine stage salmonids and these are grouped into harmful algae, such as Karenia mikimotoi, harmful zooplankton, such as Pelagia noctiluca, other environmental challenges, such as pollutants, as well as nutritional and genetic or congenital causes. The present level of understanding of these gill disorders is reviewed with regard to risk factors, potential impacting factors, methods of best practice to mitigate non-infectious gill disease and disorders, as well as knowledge gaps and avenues for future research.

“…Sea lice treatments, which should be delivered to fish in a stress-free manner (Rae 2002), range from bath treatments (e.g., hydrogen peroxide (Speare et al 1999)) to the more recent development of in-feed drugs (e.g., SLICE (Health Canada 2007)), but their effectiveness is questionable. Lice may quickly reappear after a purported successful first round of treatment with compounds such as dichlorvos (Rae 2002), an organophosphorus pesticide, which fail to kill juvenile stages of sea lice, for example.…”

The principles of organic farming espouse a holistic approach to agriculture that promotes sustainable and harmonious relationships amongst the natural environment, plants, and animals, as well as regard for animals' physiological and behavioral needs. However, open aquaculture systems-both organic and conventional-present unresolved and significant challenges to the welfare of farmed and wild fish, as well as other wildlife, and to environmental integrity, due to water quality issues, escapes, parasites, predator control, and feed-source sustainability. Without addressing these issues, it is unlikely that open net-pen aquaculture production can be compatible with the principles inherent to organic farming.
