ABSTRACT
The
diversity of aquatic resources in Thi Nai Lagoon decreased due to the lack of harmonious use and integrated long-term
planning on the use of living resources. There remained a lack of mechanisms and regulations for coordination of
activities in the lagoon by Binh Dinh
Provincial People’s Committee (PPC). The aim of the study was to investgate the aquatic
species and water quality in Thi Nai Lagoon, Vietnam.
Data were collected at 23
different points on Thi Nai Lagoon, with three replicates at each point. There were 106
species of fish presented on the lagoon and in different sizes, including 17 mollusc species and 15 crustaceans species. In the dry season, there were 167 phytoplankton species in five divisions, 10 classes in 39 orders in 59 families
including 77 genus. Zooplankton had eight chordata in 10 classes of 18 orders including
44 families, 64 genus and 102 species. Arthropoda had the largest number of species, 78
species, accounting for 76.5% of total species. In the rainy season, only 48
species of Arthropoda, Cnidaria, Annelida, Chaetognatha and
Rotifer were affected and some were not encountered in the wet season,
such as mollusca and chordata. While water quality variables were still good
for aquaculture, within permitted limits of TCVN standard and criteria, there
were still problems caused by production discharges and living activities of
inhabitants around the lagoon, such as sedimentary matters.
