FISHERIES
INDEPENDENT DATA
What
Is It and Why Is It Important?
Fisheries-independent
data are collected through scientific surveys and are a critical
component of fishery stock assessments. This type of data, combined
with fishery dependent data collected through fishermen reports,
provides a more accurate picture of stock status. Since it is
not influenced by specific management measures (i.e., size and
bag limits, season closures, mesh sizes), it presents an unbiased
accounting of stock health. Specific information includes recruitment,
juvenile and adult abundance, habitat characteristics, and environmental
factors. Fisheries independent surveys also provide an excellent
platform for gear studies to aid in bycatch reduction efforts.
