Seasonal variation of the lipid content in Trigriopus californicus (Backer) (Copepoda, Harpacticoida)

Seasonal variations of the body weight, water content and lipid amount in adult individuals of Tigriopus californicus (Backer) from peninsula Foca, Puerto Deseado (Sta. Cruz) were studied. Correlations among them were found. Experiences were realized during 1978 and 1979, using 100 individuals as op...

Seasonal variations of the body weight, water content and lipid amount in adult individuals of Tigriopus californicus (Backer) from peninsula Foca, Puerto Deseado (Sta. Cruz) were studied. Correlations among them were found. Experiences were realized during 1978 and 1979, using 100 individuals as optimun number for each test, taking them at random. Maximun values for body weight and for water content are observed during the spring and minimun values at the end of the summer. In relation to the lipid percentage (based in the dry weight) it reaches its maximum values during the spring, existing an inverse correlation with the former parameters. It was also proved the influence of the ovigerous female on the lipid content of the adult population during 1978. Maximun values were obtained in summer and minimum ones in spring, according to the population movement of the species (Lombardo y Pallares, 1981). Complementary data of nitrogen and protein percentages (based in the dry weight) during 1979 were given. In addition to the lipid and protein percentage, the calorific contenta owing to them are expressed in Kcal/g of dry weight.
