On 15-19 January 2024, Anguillid eel data was collected under the project entitled "Development of stock assessment methods and strengthening resource management measures of tropical Anguillid Eels in Southeast Asia," funded by the Japan-ASEAN Integration Fund (JAIF). This study was conducted in Palabuhan Ratu, West Java, Indonesia, and led by the Chief of SEAFDEC Inland Fishery Resources Development and Management Department (IFRDMD), Mr. Andi Soesmono. This was a monthly routine monitoring in which the fishers deploy some gear in the Cikaso and Cimandiri Rivers to support the continuation of eel catch data.
