Experimental investigation and numerical analysis to develop low-energy large-midwater trawls
China Ocean Engineering, 2017 Fuel consumption in fisheries is a primary concern because of its effects on the environment and the costs incurred by fishermen. Many studies have been conducted to reduce the fuel consumption in fishing operations. Fuel consumption due to fishing gear during a fishing operation is generally related to the hydrodynamic resistance on the gear.

A Midwater Trawl Net with Mouth Opening Canvas Devices for Stock Assessments.
NIPPON SUISAN GAKKAISHI, 1996 The purpose of this work is to develop a midwater trawl net to survey fish stock. A constant net mouth opening is necessary in order to measure fish stock densities accurately. For this purpose, canvas kites were attached to the midwater trawl net, instead of floats and weights.The area of canvas kites attached to the headrope and groundrope was ...

Comparisons of measured volume backscattering strengths with predictions based on midwater trawls [PDF]
The Journal of the Acoustical Society of America, 1981 Volume backscattering strengths have been measured close in space and time to midwater trawls in which small deep-sea fishes were caught. The acoustic experimental method was to deploy both an omnidirectional and a directional hydrophone and to detonate small explosive charges.
