Nowadays, many fish protected areas have been established, but there is still a lack of scientific research on their role of
species diversity protection, especially in Northern Thailand. To fill the knowledge gap, species diversity of fish was
carried out in the two fish protected areas located in Nampratai and Hadrai villages, Wa River, Nan province. The study
sites are managed by common agreement among villagers. Fishing is not allowed in these protected areas. Fish specimens
were collected using standard technique in March, July, and November 2013, representing dry, wet and cold seasons,
respectively. Fish scientific names were checked against the fish database and the IUCN Red List of Threatened Species.
In Nampratai village, there were 7 orders, 19 families, 47 genera, 52 species, and 1 unidentified species, while there were
7 orders, 19 families, 43 genera, 48 species, and 1 unidentified in Hadrai village. Most of the fish are in the family
Cyprinidae (47.17%). According to the conservation status, there were 4 near threatened species, 42 species of least
concern, 4 data deficient species, and 2 species not yet evaluated according to the IUCN Red List. Moreover, there were 4
endemic species under the Thailand Red Data Fishes. We also found an introduced species, Oreochromis niloticus
(Linnaeus, 1758), or Nile tilapia in both sites. Compared with the total of 60 species reported by studies in Wa River, 85%
of fish can be found in these two fish protected area. Our results showed the important role of community-based protected
area in biodiversity conservation. Knowledge from our findings will be transferred to villagers in other tributaries in Nan
that have no fish protected area in order to promote biodiversity conservation, food security and sustainable resource
utilization
