Stepped-Oblique Midwater Trawling as an Assessment Technique for Rainbow Smelt
North American Journal of Fisheries Management, 1991Abstract Discrete-depth midwater trawling for rainbow smelt Osmerus mordax at night in Lake Champlain revealed a delayed vertical migration of smaller fish and size partitioning vertically within the water column. These behavioral observations led to the development and evaluation of a nighttime stepped-oblique midwater trawling technique.

Fish behaviour in response to a midwater trawl footrope in temperate reservoirs
Fisheries Research, 2015Abstract This study addresses fish behaviour at the mouth of a midwater trawl in two temperate reservoirs. Fish distribution and behaviour were monitored using a SIMRAD EK60 (38 kHz) split-beam echosounder with the transducer deployed at the water surface, attached to the surface trawl headrope.
