Abstract

1. 1. Bile pigments from spiny dogfish (Squalus acanthias), small skate (Raja erinacea) and winter flounder (Pseudopleuronectes americanas) were quantitated after chromatography of tetrapyrroles and azopigment analysis. 2. 2. Bilirubin monoglucuronide, unconjugated bilirubin, bilirubin diglucuronide and unidentified pigments were present in decreasing order of abundance. 3. 3. UDPglucuronate glucuronyl transferase and bilirubin glucuroniside glucuronosyl transferase activities were present in all three fish livers, and had temperature optima of 37°C. 4. 4. The distribution of the two enzyme activities were different in liver fractions of the three fish.
