The observer programme (previously referred to as discard programme) commenced in 1975 as a result of an ICES resolution (ICES Council Resolution 1975/4:22) which stressed the importance of the collection of discard data as an aid to improving the assessment of fish stocks.
Data on fish discarded at sea are collected aboard commercial fishing vessels. The original aim of the sampling scheme was to sample each of the main sea areas (as per ICES regions) once per quarterly period for the five main gears - heavy trawl, seine net, light trawl, pair trawl and Nephrops trawl. However, this is continually being revised in light of changes to fishing patterns and also changes in effort by gear types.
