| Sumario: | In order to assess the patterns of variation in the biochemical composition of Mesopodopsis slabberi (Van Beneden, 1861) in a temperate estuary, we determined the protein, carbohydrate, chitin and lipid contents of freshly caught immature individuals (juveniles), adult males, and adult females during two annual cycles. Statistical analysis (anova) revealed significant differences in the biochemical components between months and development stages for the months analysed. All of the biochemical components showed significant differences between months. Environmental and trophic conditions were the main processes determining seasonal patterns of variation in biochemical composition. The results of complementary experiments carried out to estimate the effects of starvation on biochemical composition showed that the process of starvation consumed mostly carbohydrates, and also that these compounds, together with lipids, were the most affected during the refeeding period. Our findings also indicate that all body reserves were almost fully replenished during refeeding, except for carbohydrates and lipids in adult females and immature individuals (juveniles) and protein content in immature individuals (juveniles). These results indicate that responses to fasting in M. slabberi may be dependent on individual development stages, an observation that is corroborated by the significant differences in the biochemical components observed between development stages for the months analysed. Reproduction was also found to influence patterns of variation in biochemical composition. |
