There were 184 fish species from 44 families found, with some species recognized to extirpate from the Mun River. Shannon’s diversity index ranged from 1.92 to 3.14. Catch per unit of fishing effort ranged from 0.38 to 1.70 and 0.61 to 2.71 kg set-1 night-1 in down- and up-stream, respectively. Fish upstream migrations during the rainy season were observed. Incomes from fishing activities were 16,366 Thai Baht yr-1 per household. Traditional activities, especially related to fisheries, returned and income from fishing also increased during the study period. |

From the catch composition in each gear and the current market values of individual species, the current incomes that the fishers obtained from their fisheries were 37.4, 54.4 and 52.7 baht kg-1 for gillnet, longline and trap fisheries respectively. According to fishing costs per one fishing season, CpUE and number of fishing days, it was estimated that the break-even prices in the respective fisheries were 10.1, 14.8 and 10.3 baht kg-1, which indicated that the fishers have made a profit. The monitoring program and community based management on lake environments and fisheries resources as well as the fish stock enhancement program are recommended to sustain the fisheries. |
