| Abstract: | Synopsis Experimental data obtained on cyclostomes and fish concerning the levels of plasma fatty acids (PFA), their biological role as an energetic substrate, various factors affecting PFA and mechanisms involved in the control of their level are reviewed.It was shown that PFA levels in lamprey and fish depend strongly on season, circadian rhythm, nutritional state, age, sex, intrinsic activity of individuals and are regulated by some metabolites as well as hormones. The question concerning the nervous control of PFA in cyclostomes and fish needs further elucidation on account of scarce information available at present. |
