Increased mortality from fishing is expected to favor faster life histories, realized through
earlier maturation, increased reproductive investment, and reduced postmaturation growth …

In aquaculture, feeding is the primary factor determining efficiency and cost, so it is important
to know when to stop feeding to maximize efficiency. Until now, fish feeding has been mostly …

Mesopelagic fishes occur in all the world's oceans, but their abundance and consequently
their ecological significance remains uncertain. The current global estimate based on net …

It is often assumed that visual survey data provide more accurate fish counts than
conventional extractive gear. As a result, use of underwater vehicles to assess the …

the efficacy of noise-reduced vessels: a review.–ICES Journal of Marine Science, 70: 34–45 …

Change in behaviour is usually the first response to human‐induced environmental change
and key for determining whether a species adapts to environmental change or becomes …

Paul D. Winger, Steve Eayrs, and Christopher W. Glass visual and auditory stimuli produced
by the vessel, doors, sand clouds, sweeps, footgear, and trawl netting. We review the typical …

There is increasing evidence that intense fishing pressure is not only depleting fish stocks
but also causing evolutionary changes to fish populations. In particular, body size and …

Ecosystem-based management (EBM) requires more extensive information than single-
species management. Active underwater acoustic methods provide a means of collecting a …

We deployed an upward-facing echo sounder mounted on the bottom and cabled to shore in
a~ 400 m fjord location for long-term studies of small mesopelagic fish and their potential …
