Abstract

FIELD: industrial fishery. SUBSTANCE: device has selective and guiding members, cylindrical carcass defined by longitudinal and transverse ropes. Selective and guiding members are shaped as truncated conical parts and form insert. Truncated conical parts are connected with their smaller ends to define large fish passage leading into trawl sack. First conical part is defined by selective grids alternating with net inserts. Second conical part is made netted. Insert is fixed within carcass so that larger bases of conical parts are fixed at junction point of carcass and trawl netted web. Trawl has selective buffer belt defined by the system of longitudinal and transverse ropes. Selective grids positioned in alternation with net inserts are attached to the system of ropes. Trawl may be further equipped with selective grids, which may be fastened on trawl netted web between selective buffer belt and device for releasing small-sized objects, such as young fishes. Number of young fish releasing devices may be more than one and devices may be fixed in trawl sack in spaced relation one with respect to the other. EFFECT: increased efficiency, simplified construction and retention of young fishes. 4 cl, 4 dwg

Изобретение относится к промышленному рыболовству. Устройство содержит селективный и направляющий элементы, снабжено каркасом в виде цилиндра, выполненного из системы продольных и поперечных канатов. Селективный и направляющий элементы образуют вставку и выполнены в форме усеченных конусообразных фигур, соединенных между собой меньшими основаниями с образованием прохода для крупной рыбы в траловый мешок. Первая конусообразная фигура образована селективными решетками и чередующимися с ними сетными вставками, а вторая - сетная. Вставка закреплена внутри каркаса таким образом, что большие основания конусообразных фигур закреплены в месте соединения каркаса с сетной оболочкой трала. Трал содержит также селективный буферный пояс, выполненный из системы продольных и поперечных канатов и прикрепленных к ней селективных решеток и чередующихся с ними сетных вставок. Трал может быть дополнительно оснащен селективными решетками, которые закреплены на сетной оболочке трала между селективным буферным поясом и устройством для выпуска маломерных объектов промысла. Устройств для выпуска молоди может быть установлено в трале более одного, при этом они закреплены в траловом мешке последовательно на расстоянии друг от друга.The invention relates to industrial fishing. The device contains selective and guiding elements, equipped with a frame in the form of a cylinder made of a system of longitudinal and transverse ropes. Selective and guiding elements form an insert and are made in the form of truncated cone-shaped figures interconnected by smaller bases with the formation of a passage for large fish into a trawl bag. The first cone-shaped figure is formed by selective gratings and alternating net inserts, and the second is net. The insert is fixed inside the frame so that the large bases of the cone-shaped figures are fixed at the junction of the frame with the net shell of the trawl. The trawl also contains a selective buffer belt made of a system of longitudinal and transverse ropes and selective gratings attached to it and alternating mesh inserts. The trawl can be additionally equipped with selective gratings, which are mounted on the net shell of the trawl between the selective buffer belt and the device for releasing small objects of fishing. Devices for the release of juveniles can be installed in the trawl more than one, while they are fixed in the trawl bag sequentially at a distance from each other.
