The behaviour of fish was monitored in one of the lower reaches of the River Thames (England), using a BioSonics 102 dual-beam echosounder (420 kHz) with two transducers. One transducer was located in littoral (L) depths of the river whilst the other

Target strengths of brown trout, rainbow trout, roach, perch, dace and chub, crucian and common carp, bleak and bream were determined for two ultrasonic frequencies of 200 kHz and 420 kHz using dual-beam sonar directed horizontally at tethered indivi

During July and September 1993, the longitudinal distributions of fish communities in five reaches of the River Thames were obtained by mobile acoustic surveys at night, using a BioSonics dual-beam echosounder (420 kHz) with a transducer beaming hori

The 1992 survey of zooplankton structure in fourteen London supply reservoirs showed the overall dominance of large-bodied zooplankton, mainly species of Daphnia. These reservoirs can be considered as ‘anti-fish’ by virtue of their steeply slopin

Brown trout (Salmo trutta) populations of the three Orkney freshwater lochs—Boardhouse, Harray and Swannay—were studied in late September 1991 using horizontalll oriented sonar. Dual-beam echo counting during mobile surveys gave the following den

The London reservoirs sited in the lower Thames valley form part of a continuously flowing, drinking water supply system and as such have been wholly designed, constructed and operated by man for this sole function. This paper adds some information o
