Coastal fisheries are very essential for supporting the livelihoods of many rural poor in the coastal areas, particularly coastal community fisheries members. They serve as sources of food, employment and income generation for many coastal families. "Coastal Community Fisheries Catch Monitoring" Project which was conducted from April to November 2011 provides some data which indicates the importance of small-scale fisheries. The project was financially supported by the Regional Fisheries Livelihoods Programme, Cambodian component (RFLP/CMB) and was activity 1.5 of the approved RFLP CMB 2011 activity work plan and budget. For this catch monitoring study, 26 small-scale subsistence fishers, including 05 women, from five community fisheries (CFi?s) in the RFLP CMB area of geographic coverage from the four coastal provinces of Cambodia were selected and following appropriate training collected specific catch data and recorded it in fisher's logbook on a daily basis for the purpose of getting a better understanding of catch per unit of effort (CEPU), the health of inshore fish stock and the contribution of aquatic products to small-scale fisher households along the coast of Cambodia. The key data items recorded included total catchweight, catch weight by species, total catch sale price, fish price of the main species and total lengths of some key species. The study involved designing logbooks, training the selected 26 fishers as data collectors on data collection methods, collecting data from all the selected fishers, designing a database and entering all the collected data into the database, checking for errors and analyzing the collected data for final reporting and preparing report.
