2.1. Field study in two community-based protected areas
Fish specimens were collected from two community-based protected areas managed by local villagers of
Nampratai village, Nampang sub-district (18º39´23.9´´N, 101º01´20.2´´E) and Hadrai village, Saannanongmai
sub-district (18º33´25.7´´N, 100º55´43.0´´E) (Fig. 1). These two villages are selected because they have been
conserved fish for more than 12 years. For the management practice, fishing is not allowed in these two
protected areas according to the common agreement of all villagers in each village.
