Fish catch monitoring in Kang Speu, Koah Snaeng, Krabei Chrum, Samkhouy, Srae Sranok Village, Stung Treng Province, Cambodia

The objective of the research on Fish Catch Monitoring was to analyze the Catch Per Unit Effort (CPUE) specifically related to gillnet operations in six villages in Stung Treng province. The research was conducted in Kang Speu, Koah Snaeng, Krabei Chrum, Samkhouy, Sdao 1, and Srae Sranok villages. Data on fish catch were collected twice a month from two fishers in each village. The findings of the research revealed variations in CPUE values across different villages and months. In Kang Speu village, both the project site and control site exhibited fluctuating CPUE values, indicating varying levels of fishing productivity. The CPUE in the project site ranged from 50.34 in August to 30.22 in October 2022, while the CPUE in the control site ranged from 26.76 in August to 53.27 in October. The total CPUE, combining both sites, ranged from 38.55 in August in 2022 to 41.74 in October 2022. Similarly, in Koah Snaeng village, the CPUE values also varied between the project site and control site. The combined CPUE for both sites ranged from 28.16 to 47.22 over several months. In Krabei Chrum village, the CPUE values fluctuated in both the project site and control site throughout the monitoring period. The CPUE in the control site ranged from 48.62 in May 2022 to 8.75 in November and December. In the project site, the CPUE ranged from 29.08 in May 2022 to 8.22 in December 2022. In Sdao 1 village, the CPUE values showed variations, with some months exhibiting higher CPUE values and others showing lower values. The CPUE in the control site ranged from 103 in January to 8.43 in December. In the project site of Srae Sranok village, the CPUE also varied throughout the monitoring period, with the CPUE ranging from 72.8 in May 2022 to 8.80 in December 2022. Based on these findings, it is recommended to conduct fish monitoring (CPUE) in all six villages using consistent fishing gear to provide a more comprehensive understanding of fish abundance and fishing efficiency across a wider area. This will allow for more reliable comparisons between the project site and control sites. Additionally, extending the research duration to cover a full year and collecting data consistently throughout all seasons will capture seasonal variations and provide a more complete assessment of CPUE dynamics. These measures will contribute to the effective management and sustainability of fish catch in Stung Treng province
