Abstract:Individual rainbow trout Oncorhynchus mykiss were held in a specially constructed tank that enabled water to be collected separately from the anterior and posterior ends of the fish. Measurement by radioimmunoassay showed that >95% of the cortisol and melatonin released into the water originated from the anterior end (dominated by the gills). High performance liquid chromatography confirmed the identity of both hormones.
