Abstract
The article presents the first experimental data on the operation of a mid-depth trawl 18/95 m for catching vendace (Coregonus albula) in Lake Vishtynets, Kaliningrad Region. Lake Vishtynets is a testing ground for the study of industrial fishing gear. The trawl was towed taking into account the capacities of two interconnected (in a catamaran) motor boats: «Wellboat» (motor with a capacity of 25 l / s or 18,3 kW). When designing a mid-depth trawl 18/95 m, data from experiments with a floating anchor and software «Computer-aided design system for industrial fishing gear (CAD-OR)» were used. The technical characteristics of the 18/95 m trawl project were obtained. These experiments were carried out on the basis of previous studies in the Fishering Service hydrochannel.
