CUSTOM-MADE DEEP-WATER BAG SEINE NETS AVAILABLE
Deep-Water Bag Seine Net is a specialized commercial fishing net designed for deep-water surrounding operations with a large net body and dedicated bag-type catching section.
In the Chinese fishing industry, this type of net is commonly referred to as a “Sanjiaohu Net”. It is used in selected single-vessel surrounding and light fishing operations, with net dimensions and construction customized according to the vessel, fishing ground, target species and operating method.
The net is designed to surround and concentrate fish within a large fishing area before directing the catch toward the bag section. In selected fisheries, artificial lights may also be used to aggregate fish before the net is set.
Net depth and overall dimensions can be designed for commercial fishing in deeper operating areas.
The main net body can be customized to surround a substantial fishing area according to vessel and fishery requirements.
A dedicated bag section is designed to concentrate and retain the catch during the final stage of the operation.
Suitable configurations can be produced for fisheries using artificial light to concentrate schooling fish.
Deep-water bag seine nets are highly customized fishing systems. The correct specification depends on the target species, vessel size, fishing depth, existing net design and operating environment.
We can manufacture according to:
Nylon provides flexible handling and elasticity for suitable sections of large commercial fishing nets.
Polyethylene netting is available for buyers requiring different handling, weight and net construction characteristics.
Different parts of the net may use different mesh sizes and twine specifications according to their position and function.
Custom mesh, twine, depth and dimensions can be selected for the main surrounding section.
The catching bag can use different mesh and twine specifications according to the target catch and existing design.
Selected areas can use different constructions or reinforcement according to handling requirements.
Complete net assembly can be produced according to existing net plans, drawings or customer requirements.
A standard Purse Seine Fishing Net is generally described around surrounding schooling fish and closing the lower part of the net through a pursing system.
The Deep-Water Bag Seine Net described here emphasizes a deep-water operating configuration and a dedicated bag-type catching section. For this reason, existing drawings and complete net specifications are especially important when confirming production.
