Accumulation of fluorescent age pigments (FAP) was measured in pike, Esox lucius, during embryogenesis and larval development at different temperatures. Chloroform- as well as methanol-soluble age pigments from eggs and larvae were quantified. Chloroform-FAP accumulated linearly with embryonic and larval development. After yolksack resorption, FAP concentrations reached a maximum and declined thereafter. Chloroform-FAP accumulation was not temperature dependent. Similar patterns of methanol-soluble pigment accumulation were found but accumulation of methanol-FAP was, in contrast, significantly temperature dependent. As a result, methanol-FAP concentrations increased in direct proportion to the rising incubation temperature, but the maximum methanol-FAP fluorescence was found at 15° C and not at 18° C.
