Abstract
The present invention provides a kind of frequency modulation acousta induction electric propulsion purse seiner and fishing methods, the frequency modulation acousta induction electric propulsion purse seiner is mainly made of the lash ship and unmanned boat that are driven by electricity, lash ship is equipped with the device for use in fishing trawl of control platform, fish detector and other professions, and canoe is equipped with the adjustable acousta induction transmitter of frequency.The purse seiner that the present invention is traped by the way of frequency modulation acousta induction, the excessive influence acousta induction effect of ordinary diesel oil engine luggine noise is considered simultaneously, lash ship and unmanned boat are driven using the lesser electric propulsion mode of noise, to ensure that with good fishing result.
Description
Technical field
The present invention relates to aquacultures, and in particular to a kind of frequency modulation acousta induction electric propulsion purse seine fishing for ocean operation
Ship and fishing method, power are provided by electric propulsion motor, detect the shoal of fish in conjunction with fish detector, treat the shoal of fish of fishing using tune
Frequency acousta induction mode targetedly selects specific acoustic wave and is oriented trapping, is caught using purse seine combination clingfish pump mode.
Background technique
It is a kind of important physiological phenomenon that fish, which drive light reaction,.Existing purse seiner mostly drives light reaction using fish to carry out
Trapping, referred to as light-seine fishery fishing boat.Light-seine fishery fishing boat generallys use conventional diesel as power, in conjunction with the poly- fish of lamp above water with
The mode of underwater lamp attracting carries out purse seine fishing.Because of daylight impression on daytime, which can only carry out attracting work after darkness
Industry, daytime can not effectively trap encountering the shoal of fish.
Through studying, the shoal of fish also has reaction to specific frequency sound, and every kind of the shoal of fish can be by different frequency entrainment.And with
The development of fish detector, can be analyzed for the shoal of fish feature explored, judge the type of the target shoal of fish.Certain meats
Property fish can also make a response to smell, and for example shark can chase the smell of blood.
Therefore attracting by the way of light in addition to also can be used the modes such as sense of taste attracting, sound attracting.Sense of taste attracting exists
Because ocean current flow velocity is excessive in ocean, bait taste can scatter quickly, this mode also can not effective attracting.In sound attracting is usually used in
Korneforos trapping, because interior korneforos noise is smaller, trap effect is good.Conventional marine fishing fishing boat mostly uses propulsion powered by conventional energy, fishing boat
Noise itself is larger, limited using sound attracting effect.With the development of host technology, can be subtracted significantly using electric propulsion mode
Few Ship Noise, is significantly reduced the negative effect to acousta induction.Acousta induction mode can prolong significantly the activity duration compared with lamp attracting
It is long, once encountering the shoal of fish can trap, without waiting until darkness operation again.
Summary of the invention
It is an object of the invention to overcome the problems, such as that the existing light-seine fishery fishing boat activity duration limited, provides a kind of use
