Development of a new midwater sampling trawl
Fisheries science, 2002 To collect he pelagic larval and juvenile fish, several kinds of midwater trawling gear have been developed.1-4) A common disadvantage of these trawls is that depth of the net changes greatly by the towing speed. In order to overcome the disadvantages of these sampling trawls, Hu et al.

Midwater Trawling Studies in the North Pacific1 [PDF]
Limnology and Oceanography, 1959 A modified version of the Isaacs‐Kidd midwater trawl was used for 149 exploratory hauls in the Northeastern Pacific at depths ranging from 20 to 250 meters. Catches are discussed in terms of such factors as diurnal migration, seasonal variation, patchiness, and geographic variation.There was wide difference between day and night hauls.

Journal of Control Science and Engineering, 2016 An improved backstepping control method for three-dimensional trajectory tracking of a midwater trawl system is investigated. A new mathematical model of the trawl system while considering the horizontal expansion effect of two otter boards is presented ...

Journal of Marine Science and Engineering, 2023 The authors have developed a method to estimate the catch efficiency of sampling gear using acoustic information. Since different sampling conditions will cause different sampling results, it is necessary to know more details about catch efficiency to ...
