Zooplankton of Tikehau atoll (Tuamotu archipelago) and its relationship to particulate matter

The standing stock and taxonomic composition of zooplankton ( > 200 mu m) were monitored in the lagoon of Tikehau atoll from April 1985 to April 1986. The biomass of animals > 200 mu m comprised 50% of the total biomass of all organisms from 35 to > 2000 mu m. The zooplankton populations we...

Description
Summary:The standing stock and taxonomic composition of zooplankton ( > 200 mu m) were monitored in the lagoon of Tikehau atoll from April 1985 to April 1986. The biomass of animals > 200 mu m comprised 50% of the total biomass of all organisms from 35 to > 2000 mu m. The zooplankton populations were characterized by successive blooms of copepods, larvaceans, pteropods and salps, probably arising from the periodic input of detritus from the reef during windy periods. Using the C:N:P ratio method, net growth efficiencies, K sub(2), were calculated for total mesozooplankton, mixed copepods, and two planktonic species, Undinula vulgaris) and Thalia democratica . Combined with nitrogen and phosphorus excretion rates, these K sub(2) values enabled the assessment of production rates. On a 24 h basis, P:B ratios (%) were close to 100 for the total zooplankton and 54, 34 and 800 for mixed copepods, U. vulgaris) and T. democratica , respectively. These ratios are 5.7 times lower than that recorded for phytoplankton.
