Biometría, estimaciones de producción y variación estacional en la composición bioquímica de Mesopodopsis slabberi (Van Beneden, 1861) (Crustacea: Mysidacea)
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 length (CL) (TL = 2.5 CL + 0.012) and between dry weight (DW) a...

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