| The dynamic of zooplankton community and its relationship with dissolved oxygen were studied at the Soho area of Gamak Bay from 22 August to 15 September in summer. We found that zooplankton were in low abundance or absent from bottom waters when oxygen concentrations were <3 mg $L^{-1}$. The relationship between summer low-oxygen in bottom-layer and zooplankton community structure was discussed at vertical abundance in Soho area of Gamak Bay. To examine effects of bottom-layer low-oxygen on abundance and vertical distributions in the stratified Soho area, zooplankton was surveyed near-surface, within the near-bottom in the study area under a range of near-bottom dissolved oxygen conditions. There were vertical variation in total zooplankton abundance in the study area (ANOVA, P<0.05). Overall abundance of zooplankton: copepod nauplii, Oithona sp. and tintinnids were lower throughout the water column when bottom-layer DO was low (${leq}3mg;L^{-1}$). In this context it was postulated that zooplankton distribution in the Soho area of Gamak Bay might be controlled by dissolved oxygen condition. |
