    Bee Products Prevent Agrichemical-Induced Oxidative Damage in Fish
    In southern South America and other parts of the world, aquaculture is an activity that complements agriculture. Small amounts of agrichemicals can reach aquaculture ponds, which results in numerous problems caused by oxidative stress in non-target organisms. Substances that can prevent or reverse agrichemical-induced oxidative damage may be used to combat these effects. This study includes four experiments. In each experiment, 96 mixed-sex, 6-month-old Rhamdia quelen (118±15 g) were distributed into eight experimental groups: a control group that was not exposed to contaminated water, three groups that were exposed to various concentrations of bee products, three groups that were exposed to various concentrations of bee products plus tebuconazole (TEB; Folicur 200 CEâ„¢) and a group that was exposed to 0.88 mg L[SUP]−1[/SUP] of TEB alone (corresponding to 16.6% of the 96-h LC[SUB]50[/SUB]). We show that waterborne bee products, including royal jelly (RJ), honey (H), bee pollen (BP) and propolis (P), reversed the oxidative damage caused by exposure to TEB. These effects were likely caused by the high polyphenol contents of these bee-derived compounds. The most likely mechanism of action for the protective effects of bee products against tissue oxidation and the resultant damage is that the enzymatic activities of superoxide dismutase (SOD), catalase (CAT) and glutathione-S-transferase (GST) are increased.

    Thanks ABK for finding and presenting us with a link to this article. Most interesting are the concluding remarks of the authors (Daiane Ferreira,


    Helio Carlos Rocha, Luiz Carlos Kreutz, Vania Lucia Loro, Alessandra Marqueze, Gessi Koakoski, João Gabriel Santos da Rosa, Darlan Gusso, Thiago Acosta Oliveira, Murilo Sander de Abreu, Leonardo José Gil Barcellos)


    "Our data opens new possibilities for the usage of honeybee products as nutritional goods for their enhanced antioxidant properties and in aquaculture to protect fish from oxidative damage caused by environmental exposure to pro-oxidant contaminants. In addition, integrated family-based agriculture, where fish, bees and other animals are husbanded together, might facilitate the development of honeybee products for consumption and enhance aquaculture."

    ​I wonder, to what extent the antioxidant properties seen in aquaculture, are indicative of honey's influence on humans who regularly consume honey?
