The waters of northern Taiwan are one of the most productive neritic fishing grounds associated with favorable environment for marine community. This study is to investigate the biomass and distribution of zooplankton in this region. Two cruises (CR1097 and CR1142) of hydroacoustic survey, OPC measurement, net sampling with CTD observation were conducted from Ocean research No.2.
The biomass structure of zooplankton from net sampling (including abundance and biovolume) and waster mass from CTD observation (including temperature, salinity and density) in these two cruises sampling station could be classified into A and B types by using cluster analysis. While, the biomass structure within type A, had a high mean abundance and biovolume, was distributed in the type A water mass where is the eddy/upwelling area with low temperature and high salinity. Conversely, the biomass structure within type B, had lower mean abundance and biovolume, was distributed in the type B water mass where is affected by the Taiwan Strait Warm Current with high temperature and low salinity.
Furthermore, the regression analysis shows that the abundance, biomass and biovolume of zooplankton made by net sampling, hydroacoustic survey and OPC measurement are significant correlation between each other.
