Data & Monitoring
Monitoring fisheries to collect data is an essential component of fisheries management. Fisheries managers are using the data to monitor fishery status, for example changes in catch rates, recruitment, biomass and a range of other important indicators. Data collected are used to make informed management decisions in setting fisheries rules such as catch limits, effort limits, minimum lengths, and fishing gear that can be used.
Common types of data collected include catch weight or number, the amount of effort used (e.g. number of hooks used or hours fished), the size and age of fish caught, the amount of bycatch and interactions with protected species. These data can be collected by fishermen in logbooks, by observers working on fishing boats, in ports or undertaking creel surveys, during scientific surveys or using electronic monitoring such as video cameras and vessel monitoring systems (VMS).
