Carbon, nitrogen and phosphorus stoichiometry of crustacean zooplankton in the Baltic Sea: implications for nutrient recycling
The carbon (C), nitrogen (N) and phosphorus (P) contents (% of dry weight) of some crustacean zooplankton were studied in the Baltic Sea. The copepod Acartia sp. had a stable C and N content (48.3 ± 0.8% C, 12.4 ± 0.2% N, C:N ratio 4.5 ± 0.1). The P content was variable (1–2%), probably depending on...

The carbon (C), nitrogen (N) and phosphorus (P) contents (% of dry weight) of some crustacean zooplankton were studied in the Baltic Sea. The copepod Acartia sp. had a stable C and N content (48.3 ± 0.8% C, 12.4 ± 0.2% N, C:N ratio 4.5 ± 0.1). The P content was variable (1–2%), probably depending on developmental stage and season. Copepods accumulating fat, like Pseudocalanus minutus elongatus , had higher and more variable C content (50–60%), and lower N and P content (7–12% N, 0.6–1.5% P). The highest C and lowest N and P contents were found in adult Limnocalanus macrurus . However, the N:P ratio was apparently independent of fat content and between 14 and 27 for all copepods. The cladocerans Bosmina longispina maritima and Evadne nordmanni had lower N content (9.3–10.8%) and higher C:N ratio (5.1–5.7) than Acartia sp.
