Webber Biología waste water eutrophic zooplankton Kingston Harbour Previous extensive studies of zooplankton distribution in the eutrophic Kingston Harbour established that it was being continuously contaminated. We assessed the community in 2011, 17 years after a previous study and five years after the introduction of a tertiary waste water system. Sampling was conducted for four weeks at eight stations identical to those sampled in a previous study. We used horizontal surface tows with a 200μm net. A total of 73 zooplankton taxa were identified and copepods dominated with 20 species. Mean total abundances were high, ranging from a minimum of 2 383 animals m -3 in the southern region of Hunts Bay to 194 166 animals m -3 at the Inner Harbour. Five zooplankton taxa ( Acartia tonsa, Paracalanus spp., Temora turbinata, Penilia avirostris and Lucifer faxoni ) that were previously identified as indicators, were again important in the Harbour. The overall zooplankton abundances were similar and in some cases higher than the previous study. There was no significant improvement in the water quality since the introduction of the treatment system at Soapberry. This may be a result of unknown nutrient inputs or of nutrient remaining in the sediments. 2014 artículo científico 0034-7744 https://www.redalyc.org/articulo.oa?id=44932432022 en http://www.redalyc.org/revista.oa?id=449 Revista de Biología Tropical application/pdf Universidad de Costa Rica Revista de Biología Tropical (Costa Rica) Num.3 Vol.62 |
