Walleye pollock (Theragra chalcogramma) behavior in midwater trawls

Fisheries Research, 2013
Abstract Trawls are standard tools for surveying fisheries resources, yet they are selective in what they retain, and thus provide potentially misleading information about fish populations. In order to evaluate the potential for selective retention in a midwater survey trawl used in conjunction with acoustic surveys of walleye pollock, fish behavior ...

Simple Closing Midwater Trawl for Small Boats

North American Journal of Fisheries Management, 1989
Abstract A closing midwater-trawl system for a small boat (7 m) was developed to apportion hydroacoustic population estimates among fish species by collecting vertically stratified limnetic fish samples. These stratified samples could also be used for providing biological data on the fish or for feeding and behavior studies.

One-boat midwater trawling with unequal panelled trawl [PDF]

, 1983
Results of the comparative efficiency studies with 10.5 m equal panelled and 10.3 m unequal panelled midwater trawls operated from 10.9 m wooden trawler are presented. Out of the two nets, the latter proved to be relatively good for the capture of off bottom and column fishes like pomfrets, seer, lactarius, catfish, silver bar, ribbon fish and an ...

Fish behaviour in response to a midwater trawl footrope in temperate reservoirs

Fisheries Research, 2015
Abstract 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.

Depth control of a midwater trawl gear using fuzzy logic

Fisheries Research, 1995
Abstract This paper describes the model of a simplified trawl system and the design of a control system that uses a fuzzy algorithm in controlling the depth of a midwater trawl net. The practicality of the control system was examined using computer simulation.
