Abstract
Использование: в промышленном рыболовстве при траловом лове. Сущность изобретени : в процессе перемещени оруди лова контролируют концентрацию гидро- бионтов на входе в накопитель. При накоплении гидробионтов перед входом равномерно снижают скорость перемеще-- ни оруди лова. При траловом лове регулируют глубину хода трала при снижении скорости тралени путем изменени длины вытравленных ваеров. 1 з.п.ф-лы, 1 ил.Usage: in industrial fishing with trawling. The essence of the invention: in the process of moving a fishing instrument, the concentration of hydrobionts at the entrance to the reservoir is controlled. With the accumulation of aquatic organisms in front of the entrance, evenly reduce the speed of movement of any fishing gear. In the case of a trawl, the depth of the trawl is adjusted while reducing the speed of trawling by changing the length of the etched warp. 1 hp ff, 1 ill.
Description
Изобретение относитс к промышленному рыболовству, в частности, к лову тралами . This invention relates to industrial fishing, in particular, to trawl fishing.
Цель изобретени - повышение эффективности лова путем периодического уменьшени подпора у входа в мешок оруди лова.The purpose of the invention is to increase the efficiency of fishing by periodically reducing the backwater at the entrance to the bag of fishing gear.
Дл этого в процессе перемещени оруди лова после накоплени гидробионтов у входа в мешок скорость перемещени оруди лова снижают до захода гидробионтов в мешок, а затем ее вновь увеличивают до номинальной.For this, in the process of moving a fishing instrument after accumulation of hydrobionts at the entrance to the bag, the speed of movement of the fishing instrument is reduced to the entry of hydrobionts into the bag, and then it is again increased to the nominal value.
На чертеже изображено устройство дл реализации способа на примере тралового лова.The drawing shows a device for implementing the method on the example of trawling.
Устройство включает трал 1, на котором установлен прибор 2 дл контрол концентрации гидробионтов у входа в мешок, кабели 3, траловые доски 4, ваера 5.The device includes a trawl 1, on which the device 2 is installed to control the concentration of hydrobionts at the entrance to the bag, cables 3, trawl boards 4, warps 5.
СпосоЬ осуществл ют следующим образом .The method is carried out as follows.
В процессе тралени у входа в мешок образуетс подпор, который преп тствует заходу в мешок гидробионтов. За концентрацией гидробионтов в этой зоне наблюдают с помощью прибора контрол In the process of trawling at the entrance to the bag, a backwater is formed, which prevents entry into the bag of aquatic organisms. The concentration of hydrobionts in this zone is monitored with the help of a control device.
концентрации гидробионтов, например эхолота . После образовани у входа в мешок плотного скоплени скорость тралени снижают (уменьша тем самым подпор) до тех пор, пока с помощью прибора контрол не установ т, что гидробионты зашли в мешок. Чтобы в результате уменьшени скорости глубина хода трала не увеличилась более, чем на 5-7 м, врем снижени скорости и врем на заход гидробионтов в мешок не должно превышать 2-3 мин. В необходимых случа х вли ние снижени скорости тралени на глубину хода трала компенсируют уменьшением длины ваеров.concentrations of aquatic organisms, such as sonar. After the formation of a dense cluster at the entrance to the bag, the speed of trawling is reduced (thereby reducing the backwater) until it is determined with the aid of the control device that the hydrobionts have entered the bag. In order that, as a result of a decrease in speed, the depth of the trawl does not increase by more than 5-7 m, the time of decrease in speed and the time required for the entry of hydrobionts into the bag should not exceed 2–3 minutes. In necessary cases, the effect of reducing the speed of trawling on the depth of the trawl is compensated for by reducing the length of warp.
Рассмотрим пример конкретного осуществлени способа на примере лова мелкой ставриды с судов типа РТМС. Номинальна скорость тралени 2,2 м/с. Концентрацию гидробионтов у входа в мешок определ ют одним из датчиков улова прибора контрол процессов тралового лова SIMRAD FR-500, установленным в конце мотни трала.Consider an example of a specific implementation of the method on the example of fishing for small scad from ships of the RTMS type. The rated trawling speed is 2.2 m / s. The concentration of aquatic organisms at the entrance to the bag is determined by one of the catch sensors of the SIMRAD FR-500 trawl fishing process control device installed at the end of the trawl winder.
По результатам наблюдений за работой прибора установили, что у входа в мешок образовалось плотное скопление ставриды. За 1,5 мин скорость тралени снизили доAccording to the results of observations on the operation of the device, it was established that a dense accumulation of scad formed at the entrance to the bag. 1.5 min speed trawling reduced to

1,3 м/с. По показани м прибора установили , что при такой скорости скоплени ставриды зашло в мешок. Затем за 1,5 мин скорость тралени увеличили до номинальной . Так как за 3 мин снижени скорости тралени глубины кода трала увеличилась не более, чем на 5 м, длину вытравленных ваеров не уменьшали.1.3 m / s According to the testimony of the device, it was established that at such a speed the accumulation of scad went into the bag. Then, in 1.5 minutes, the trawling speed was increased to nominal. Since the trawl code depth increased by no more than 5 m in 3 min. Of decreasing trawling speed, the length of the etched wargs was not reduced.
