Catch Assessment Survey
CAS
Fisheries Catch Assessment Surveys (CASs) play a pivotal role in generating essential information concerning fish catches and fishing effort. These surveys provide a comprehensive set of indicators, including catch per unit effort (CPUE), catch volume, catch value, and the fishing effort, such as the number of boats and fishing gears used by size. Additionally, CASs offer valuable insights into changes in the abundance of key fish species. The information gathered through CASs is indispensable for several critical purposes, including development planning, policy formulation, and effective fisheries management.
