Description

Pelagic sea fishing cage.

Technical sector

The invention falls within the technical sector of Fishing and marine aquaculture.

State of the art

Fishing for pelagic species and more specifically the fishing of large migrants, such as tuna, mainly uses four spare fishing gear known and about which there is extensive descriptive literature. It is, first of all, the fixed type or traps; second, from longline fishing; third, of fishing with rod; and, fourth, of fishing to the fence.

Until recently, these four systems of fishing did not allow the temporary establishment of catches; already That the fish was immediately slaughtered.

Recently new techniques have been developed of transport and housing of live fish that allow transfer a school from an unencumbered fence network to a floating cage with enough draft to accommodate inside a biomass captured of about 150 tons.

Specifically, in the tuna fishing sector in Japan, Australia and in the Mediterranean, tuna is transferred I live from encirclement arts to transportation and housing cages, following the sequence of maneuvers described to continuation.

Once the tuna vessel is openwork, the transfer cage is towed to the position, with the net surface boring to avoid hydrodynamic resistance to the advance. When in position, the net of the cage is released and the fence of the fence art is tied to the floating structure of the cage The transfer gates of the encirclement network and the transport cage and housing are allied. Ship tuna fishing vessel near the turn maneuver of the corchera and azocado of its art, reducing of such luck the volume in which the captured school is found. The latter will go to inside the cage through the transfer doors when it no longer supports its density inside the art of fishing. Once the transfer is made, the doors are closed, the fence art cage is disconnected and the cage is ready to be towed to its holder where it will be properly anchored

The aquaculture and / or housing industry of Live fish uses a host of different types of cages. The two types that are used with greater extension are the cages of submerged type and gravity cages whose floating structures They are usually made of high density polyethylene (HDPE) or metallic.

Description of the invention

The technical problem posed is that what characterizes the types of cages described in the state of the technique is that they are only transport and containment mechanisms of live fish These are cages that can be described as passive since they don't have the ability to fish, that is, to be the art of fishing while transport and containment mechanism of the captured biomass

The technical advantages provided by this invention is that the pelagic sea fishing cage is the unique in its kind that allows, at the same time, capture, transport and Stable any type of pelagic fish. Its low cost, in I take 20% of the value of a purse-seine fishing vessel or longline, make it the most profitable fishing art and easily amortizable. Your ability to maintain a biomass established, will allow its operator, a more effective management of the quality of your fishing, greater added value and an increase in the degree of direct control over the times and rates of fished and production.

The pelagic sea fishing cage is a novel fishing system, housing and transport of live fish applicable to all kinds of pelagic species, from tuna, Horse mackerel, sardine and / or mackerel, even cephalopods such as squid.

The operation of the cage system of Live fish of the present invention is inspired by techniques of Fishing used by whales and dolphins. This operation is briefly described below.

The pelagic marine fishing cage is towed to the deep sea fishing area. To allow a trailer Quick and easy, the cage is towed with its floating structure, its network curtain system and its submerged structure of ballasted, collected and surface drilled.

Depending on the species that you want to fish, the mono-tubular structure is submerged ballast connected to the tri-tubular structure Floating through cables. The operators of this type of cage they can choose the length of the connection cables and, therefore, the Cage work level. This is done by actuation. of lifting and lowering apparatus of mechanical, electrical type, pneumatic or oil-pneumatic such as windlasses, drums, toners and / or winches, located on the surface.

Once deployed to the desired dimension, the cage, in its fishing position, it maintains its curtain systems retracted network verticals. The upper net curtain is folded to the submerged keel of the structure tri-tubular floating while drapery lower is folded to the structure mono-tubular submerged ballast.

The mono-tubular structure of weighted submerged to a predetermined level, it also serves as rack to a network of circular shape and that will serve as background of the cage once it is closed.

In order that the fish cannot detect any human presence on the structure tri-tubular floating and / or central turret floating maneuver, a water pump, located in said turret, distributed through a properly perforated pipe, a sufficient seawater flow so that this in turn is sprinkled on the surface of the sea, inside and outside from the perimeter of the cage, making it impossible for the fish to see through of the water surface.

Systems are positioned and operated attraction of fish from the floating central turret of maneuvers in the center of the cage as follows:

?

It is placed to a previously established depth, a light source, whose characteristics have been determined based on the species of pelagic fish that you want to attract by bait light;

?

a submersible speaker whose technical characteristics have been established according to the power and volume required for each  species of pelagic fish that you want to attract by bait sonorous;

?

a closed basket with live bait previously determined based on the species of pelagic fish that you want to attract.

Once the fish has been attracted to the center of the cage is baited with bait from the central floating turret of maneuvers until he loses his sense of danger. I accomplished this, they are operated together from the floating central turret of maneuvers,

?

a compressor high pressure air, which is connected to a system of bottles of compressed air that in turn feeds by high pressure air hose, a bubble curtain system of air composed of perforated pipe sections, installed in the upper part of the lower net curtain;

?

a fountain of laser light that feeds a series of fiber optic cable of laser light bulbs installed in the submerged ballast tube. These bulbs activate a virtual curtain of laser beams, outside the curtain of air bubbles. The combined effect of the ascending air bubbles and the laser light beams is the of a virtual wall that the fish will not cross.

When, after a few seconds, the first bubbles reach a certain level, it is operated from the turret floating control unit, the quick-release system of the upper and lower systems of vertical net curtains, using a vacuum boiler connected to a compressor of air.

The superior vertical curtain system of net, heavily ballasted and composed of materials negative buoyancy, submerges at a certain speed depending on the amount of ballast used.

The ballast tubes of the upper system of vertical net curtains and curtain system pipes of air bubbles from the bottom system of vertical net curtains they are connected, like a lanteon, by halyards that run on toothed sheaves housed in each section of the floating tri-tubular structure like a motor, so when the upper system of vertical net curtains submerges, the weight of the latter drags in reverse the lower net curtain.

The circulating air inside the pipes that make up the installed air bubble curtain system at the top of the lower vertical curtain system network, purge these pipes from the water inside giving it positive buoyancy to the lower vertical curtain system of net.

In a few seconds, the upper systems and bottom of vertical net curtains that have the same dimensions, are halfway, thus closing a net cylinder and catching the fish inside it, unable to leak because the bottom of the cage, consisting of a ballasted submerged mono-tubular structure, is closed by a circular network sponsored to said structure.

Depending on the species of pelagic fish that if you want to capture this guide, the mesh lengths will be chosen of the networks to be used. Thus, to fish tuna nets will be chosen with a minimum mesh 7 centimeters long by \ diameter5mm Of thread. For smaller species these will be reduced measurements.

       \ newpage
    

In the same way it can be expanded or reduced by equal proportion of the diameters of the structure tri-tubular floating and structure mono-tubular submerged ballast, increasing or reducing the number of sections that make up the structure tri-tubular floating and in the same proportion, the perimeter of the submerged mono-tubular structure ballast.

So, the principle of fishing through the cage Pelagic fishing marine is invariable, it's just about resize some aspects of the cage and adapt the baits lighting and sound in order to better adapt their capabilities Fish to the desired species.

Embodiment of the invention

For all purposes, the description of the cage pelagic fishing marina set out below corresponds to that of a cage for fishing, transportation and tuna housing live and species of equal size; which is not intended to be limiting of its scope, in the sense that said cage can be adapted Easily fishing for pelagic species of smaller size. To do this, simply resize the diameter of the cage, the maximum draft of the same, the net mesh light and the diameter nominal of the thread as well as adapting the light and sound baits to the pelagic species that you want to capture.

For all purposes, the description of the cage Pelagic marine fishing set out below, does not claim be limiting of its scope, in the sense that its dimensions they can be extended, allowing greater catches. For this will be enough to resize among others and in equal proportion:

?

the diameter of the floating tri-tubular structure by adding as many sections as necessary,

?

The number of vertical upper and lower net curtains,

?

the draft maximum pelagic marine fishing cage,

?

the perimeter of the submerged mono-tubular structure of ballasted

For all purposes, the marine fishing cage pelagic must be towed to a deep-sea fishing area previously determined based on the pelagic species that Want to capture. To allow a quick and easy trailer, the cage it is towed with its floating tri-tubular structure (1), its upper and lower vertical curtain systems of net (2) and its submerged mono-tubular structure of ballasted (3), collected and drilled on the surface, offering in this way a lower hydrodynamic resistance to the advance and by both higher towing speed.

Once you have reached the fishing area and depending on the pelagic species that you want to capture, from the amount of fish that you want to contain in the cage and / or the probe of the fishing ground where the marine fishing cage is located pelagic, operators of this type of cage may hoist or submerge the ballast mono-tubular structure (3) connected to the floating tri-tubular structure (1) by means of cables (101), determining in this way the draft of the cage and therefore its work level. This is done through the operation of lifting and lowering apparatus (102) of type mechanical, pneumatic and / or oil-pneumatic control the movement of the cables (101) and at the same time serve as this by the same while they are not used.

H.

A background network (eleven). The bottom network (11) is circular. Your radio is the same as the inner radius of the mono-tubular structure submerged ballast (3). The type of network used for your confection is without knot (72). The diameter of the thread used as well as the mesh length of the network vary depending on the species that Want to capture. Thus, for example, to capture tunas, you will use a \ diameter5mm thread and a mesh length of 7 to 9 cm. The backbone network has a negative buoyancy. The pesos Specific materials used for making are higher than seawater (1,015-1,028) depending on the fishing ground in which the marine cage is going to be used Pelagic fishing This network is ballasted by ropes radial (73) and concentric perimeter of ballasted cape (74 and 75). The cage operators tie the perimeter reling outside (75) of the backbone network (11) to each of the rings mooring (70) of the mono-tubular structure of submerged ballast (3), thus achieving that the background network (11) It is fully extended and tensioned.

How to use the invention

Once in the fishing area and depending on the species that you want to fish, you proceed to submerge the structure ballast submerged mono-tubular (3) connected to the floating tri-tubular structure (1) by cables (101). Operators of this type of cage can choose the length of the connection cables and therefore the work level Maximum of the cage. This is done by the drive (120 and 121) of lifting and lowering devices of mechanical type (102). A once deployed to the desired level (122), the marine fishing cage pelagic in its fishing position maintains its inferior system of vertical net curtains (10) and its superior curtain system Vertical net (9) folded: The upper curtain system vertical network (9) is folded to the submerged keel tube (12) of the floating tri-tubular floating structure (1), while the lower system of vertical net curtains (10) is folded to the mono-tubular structure submerged ballast (3). The structure mono-tubular submerged ballast (3), submerged to a predetermined dimension, serves as mooring frame for the network of bottom (11) that will act as the bottom of the cage once it It is closed.

In order that the fish cannot detect any human presence on the structure tri-tubular floating (1) and / or the central turret floating maneuver (8), a water pump distributed by a perforated pipe, a sufficient flow of seawater to that this in turn be launched by sprinkling on the surface of the  sea (inside and outside the perimeter of the cage), making it impossible to fish see across the sea surface (123).

Systems are positioned and operated Fish attraction from the maneuvering turret in the center from the cage (123):

?

It is placed to a previously established depth, a light source whose features have been determined based on the type of pelagic that you want to attract through light bait.

?

A submersible speaker whose technical characteristics have been established according to the power and volume required for each type of pelagic that you want to attract by bait sonorous.

?

A closed basket with live bait previously determined according to pelagic that you want to attract.

Once the fish attracted to the center of the cage (124), it is primed until it loses its sense of danger (125). Once this is achieved, it is activated, from the maneuvering turret and joint way (126 and 127):

?

A compressor high pressure air (141), connected to a bottle system of compressed air (140) that are fed by hose (111) of high pressure air, an air bubble curtain system composed of perforated sections of pipe (93), installed in the top of each of the curtains that make up the system bottom of vertical net curtains (10).

?

A fountain laser light (152) that feeds by fiber optic cable (169), a series of laser light bulbs installed in the tube submerged in ballast. These bulbs activate a virtual curtain of Beams of lasers, outside the curtain of air bubbles. Air bubbles act as a magnifying glass.

The combined effect of bubbles and light laser is that of a virtual wall that the fish will not pass through (127).

When after a few seconds, the first bubbles reach a certain level, the system is activated zapped upper net curtain (128).

The upper system of vertical net curtains (9), composed of negative buoyancy materials, is submerged at a certain speed depending on the amount of ballast to be used

With the ballast tubes (87) of the system upper vertical net curtains (9), connected, by lanteon rigs, at each of its ends to each of the perforated tube ends (93) of the lower system of vertical net curtains (10), the top curtain system vertical network (9), in its immersion movement, lifts towards surface the bottom system of vertical net curtains (10)

Once the pressurized air is injected into the inside the tubes (93) of the bubble curtain system of air, an air chamber will be formed inside said tubes (93), giving the lower system of vertical net curtains (10) positive buoyancy enough to ascend without major difficulty.

In a few seconds, both draperies meet halfway (129), thus closing a network cylinder and catching the fish inside him, unable to escape due to that the bottom of the cage is closed with a circular net.

Once the fish caught and the cage closed, the standard tow tubes for said cage (130) are placed. The properly equipped cage is towed 5 (131) to destination. Trailer tubes (132) and tow pole (133) prevent deformation from the vertical network walls (134) to the bow of the cage, avoiding this way the live transported fish feels squeezes during the blast.
