WGFAST holds state-of-the-art expertise in advanced
acoustic-trawl survey techniques, and employs these techniques on a wide
range of platforms including research vessels, ships of opportunity, and observatories.
The working group was created in 1984 following a
recommendation from the ICES Fish Capture Committee in 1982. It has been a key
group internationally in developing acoustic trawl surveys and throughout its
lifetime the focus has shifted from solving the technical challenges of reliable acoustic measurements to the use of acoustics to observe key
biological parameters such as biomass indices, behavioural metrics, and
acoustic species classification. The group has recently expanded its
core activities to include the use of acoustics to study marine ecosystems on a
wide range of observation platforms.
At approximately 5-7 year intervals, WGFAST organizes a symposium to facilitate information exchange
among fisheries acousticians, physicists, engineers, biologists, and
ecologists. Six previous symposia have been held:
proceedings from these conferences reflect the historical development
from acoustic-trawl surveys to addressing broader interests in applied aquatic observation
