Summary: | The potential of catch per unit effort (CPUE) analysis based on statistics of local fisheries in Tonle Sap Lake in Cambodia was evaluated. The fishery statistics system was improved through a cooperative project conducted by the Department of Fisheries and the Mekong River Commission between 1994 and 2000, especially in the seven provinces adjacent to Tonle Sap Lake. However, the fisheries statistics were not effectively utilized for sustainable stock management. After the cooperative project, fish catch data sorted by species or species group were collected at the province level in the seven provinces. Another recent project also revealed the numbers of fishing gears that operated in the seven provinces. The CPUEs of ten species in Kampong Thom Province—including
Channa micropeltes
and
Cirrhinus
spp.—could be calculated from 1994 to 2007, because these are caught solely using bamboo fence systems or barrages. CPUE analysis clarified that stocks of high-price fishes such as
Ch. micropeltes
,
Hampala
spp., and
Pangasius
spp. have deteriorated while those of relatively low-price fishes such as
Cirrhinus
spp.,
Cirrhinus microlepis
,
Cyclocheilichthys enoplos
, and
Channa striata
have increased in recent decades. |
