Instrumentation that uses underwater acoustics to monitor the behaviour and growth of
salmon and trout in open water fish farms has been successfully developed. The vertical …

The purpose of this project was to determine the practicality and characteristics of a remote
monitoring system for an open ocean aquaculture fish cage. The Open Ocean Aquaculture …

A challenge for the aquaculture community has long been the development of harmless
techniques for monitoring fish in a tank. Acoustic telemetry has been used to monitor fish …

This paper describes a hydroacoustic system for monitoring and feeding control in cage
rearing of Atlantic salmon. An echo-sounder, linked to an upward-facing transducer mounted …

A self-contained data collection system is described that was used to investigate the
behavior of Atlantic cod (Gadus morhua) in an offshore net pen (Sea Station 3000) located …

The fisheries profession is not immune to the pressures for increased efficiency which have
characterized the history of human society. Currently, much of fisheries research and …

In 2001 the US Army Corps of Engineers, Portland District (OR, USA), started developing the
Juvenile Salmon Acoustic Telemetry System, a nonproprietary sensing technology, to meet …

Two novel acoustic transmitter tags intended to reflect feeding behaviours in farmed Atlantic
salmon (Salmo salar L.) were developed and tested in this study. Using information from the …

Small acoustical transmitters may be used to obtain data from tree swimming fish. The main
principles behind this technique are described together with some of the equipment …

The health and welfare of farmed fish are highly dependent on environmental conditions.
Under suboptimal conditions, the negative impact on welfare can cause changes in fish …
