Biometry, estimates of production and seasonal variation in the biochemical composition of Mesopodopsis slabberi (Van Beneden, 1861) (Crustacea: Mysidacea)

摘要: Morphometric relationships in Mesopodopsis slabberi (Van Beneden, 1861) were determined using freshly caught specimens from the Mondego estuary (western Portugal). Significant positive correlations between total length (TL) and cephalic (CL) (TL = 2.5 CL + 0.012) dry weight (DW) (ln DW 3.0298 ln TL ‐ 6.0229) found. The annual production was 13.17 mg ⋅m‐3 ⋅year‐1, P/B ratio 9.32. This turnover rate supports hypothesis that M. plays an important role estuary’s food web. Contents of proteins, carbohydrates, chitin, lipids, phospholipids, cholesterol juveniles, males, females throughout year. Statistical analysis (ANOVA) revealed significant seasonal differences biochemical composition, as well among females, males. Environmental conditions (e.g., trophic conditions) reproduction appeared to be main processes influencing patterns variation composition.
