Investigation of the effects of rainbow trout (Oncorhynchus mykiss) skin mucus against indomethacin-induced gastric damage in rats.

A peptic ulcer is a stomach lesion. It is generally caused by malnutrition, the use of anti-inflammatory medications, and an imbalance between mucosal defense systems. In fishes, the lubricous substance that called mucus secreted from the skin, prevents the entry of microorganisms that can enter the body through the skin.

Supplementation of sea buckthorn (Hippophae rhamnoides L.) oil in the diets of freshwater rainbow trout (Oncorhynchus mykiss W.) led to enhanced growth and better meat quality.

In this study, sea buckthorn oil (SBO) was added to rainbow trout fish diets at 0.25%, 0.5%, and 1% rates in order to determine the effects on growth, feed conversion rate, survival rate, fillet quality, and physiological, biochemical and histopathological parameters.
