The overall aim for statistics on catch and landings is to report on the contribution of capture fisheries to national and regional economies, to the provision of food (subsistence) and on the total removal of fish and other organisms from...

Data collection
Where possible, logbooks are recommended for use in capture fisheries to record inter alia the components of the catch used to derive catch statistics. Care is needed when quantifying the catch components at-sea as the accuracy of the measurements...

Diagrammatic presentation of catch concepts and relationships in a generalized capture fishery. Concepts are defined in the glossary and represent the components of catch which may result from fishing operations. Note that nominal catch approximates the amount of biomass that...
