[Percent composition of fatty acids in Tigriopus fulvus from rocky pools on the Ligurian coast (Copepoda harpacticoida)].

The study concerns the Tigriopus fulvus specimens fatty acid composition, sampled in Ligurian coast rockpools from September 1980 to June 1981. By the study of frequency distribution it was observed that the fatty acid found in greater quantity was the palmitic one, followed by the palmitoleic, the oleic and stearic acids. Short and long chain fatty acids are less frequent. Investigation about each fatty acid concentration shows that the seasonal trends between males and females are different and the trend of some fatty acids (e.g. linolenic and stearic acid) is characteristic.
