ABSTRACT

Ben Tre is a coastal province in the Mekong Delta The local people live in knit and depend largely on nature especially on the fishery However, in recent years, the catch and growth of fishery and aquaculture in Ben Tre are facing many difficulties Their quantity and productivity are continuously decreasing The main reason is due to the impact of global climate change The environment of creatures

close-in mangrove forests close-in Ben Tre is changed because of the direct impact of climate change The saline intrusion in this area is serious and complicated The project which has conducted on Ba Lai and Rach Con Bung river belongs in 3 coastal districts in Ben Tre studies the level of zooplankton diversity and the impact of climate change through the saline level in the surveyed area from June 2018 to September 2019 The analysis of regional zooplankton diversity is based on the calculation of the number of species of Margalef (d), Shannon ± :LHQHU +¶  -¶ DQGWKHFRUUHODWLRQEHWZHHQWKHQXPEHURIVSHFLHVDQGZDWHU¶VVDOLQLW\,QWLPHVRIresearches, 58 taxa zooplankton were found and recorded with the dominant species DUH&RSHSRGDDQG5RWLIHUD+¶VLQGH[UDQJHVIURPRQWKH5DFK&RQ%XQJULYHU

to 1.96 on the Ba Lai river The increase in water salinity is the reason for the growth in the number of taxa in the saltwater environment In consequence, the biodiversity and zooplankton density is reduced in the estuaries and it threatens to the survival and growth of valuable aquatic larvae From the evaluation results, people should make the suggestion of measures to manage and maintain biodiversity in the mangrove forests in Ben Tre to have the most suitable and long ± term action plan for adaption to climate change
