Abstract

Primary assessments of fish catch from AR sites are done by ICAR-CMFRI, following a multistage stratified random sampling (MSSRS) technique introduced by the Institute to assess marine fish landings in the maritime states of India (Srinath et al., 2005). Hooks and lines and gillnets operated from traditional boats and motorized FRP boats are usually the chief gears monitored for fish catch assessments from AR sites. The villages or landing centres having AR are surveyed on a fortnightly basis as per MSSRS and the fishes landed by boats fishing in the AR site are identified and quantified. For comparison, the landings from non-AR sites (either in the same village or in the adjacent village without AR, if the former does not happen) are also surveyed simultaneously. The monthly catch from AR and non-AR sites are compared over a year or more. The catch from an AR site is also compared with the catch recorded in the previous year from the same site before the deployment of AR, obtained from the database of ICAR-CMFRI.
