Abstract

A device designed for rapid deployment around a floating fish cage net. Deployed as a floating packaged impermeable nonorganic membrane that drops to form a curtain by releasing draw ropes (4) which run through a series of rings mounted on the vertical plane (5) and fully encloses the bottom of the fish cage net by pulling on a lanyard (7) which runs through a series of rings (6) mounted along the bottom and end of the impermeable nonorganic membrane (1). Rapid retrieval of thisdevice is facilitated by reversing the above procedure which causes the impermeable nonorganic membrane (1) to form a floating elongated concertinaed package.

Description

RAPID DEPLOYMENT FISH CAGE ENCLOSURE
This invention is a device designed for enclosing floating fish cages located in the sea, in a river or in a lake. Designed mainly for but not exclusively for the chemical bath treatment of fish being held in those cages.
The chemical treatment to medicate fish held within floating cage nets requires deployment of a tarpaulin enclosure around the floating cage. A measured amount of medication solution can be added to a known volume of water. The fish are held within this solution for a timed period, the tarpaulin is then removed to allow a fresh supply of water and oxygen to the fish. Currently available are tarpaulin curtains and full enclosures but the deployment and retrieval of these devices is time consuming necessitating boats, cranes and men working for a considerable period of time to enclose a single cage net. This operation is time critical due to the tides and currents.
To overcome the above problem this invention makes possible the quick deployment and retrieval of a packaged impermeable nonorganic membrane. With a floatation collar at the top and a weighted lead-rope at the bottom it is concertinaed along the horizontal plane. This elongated concertinaed impermeable nonorganic membrane is held in shape by draw ropes, pulled tight. These draw ropes run through a series of rings mounted on the vertical plane. The floatation collar and the compact nature of this concertinaed package allows for quickly deployment around the fish cage net. One or more concertinaed membranes may be required to encircle the fish cage net completely. By releasing the draw ropes the lead-rope sinks taking the bottom of the membrane down and forming a curtain. The bottom and ends of this impermeable nonorganic membrane incorporates a series of rings with a lanyard running through them, designed in such a way that allows the bottom of a fish cage net to be completely enclosed when the lanyard is pulled tight. Once the medicated treatment of the fish is complete the impermeable nonorganic membrane can be simply retrieved by releasing the lanyard allowing it to form a curtain again then concertinaing it along the horizontal plane by pulling up on the draw ropes. The floating concertinaed package can now be quickly retrieved from the water.
An abrasion panel is attached to the top of the impermeable nonorganic membrane to prevent chaffing of both the impermeable nonorganic membrane and the floatation collar against the side of a fish cage. The invention will now be described by way of reference to the
accompanying drawings.
Figure 1 on page 1/3 being the front or back elevation of the impermeable nonorganic membrane 1 hanging in the water as a curtain, open from its concertinaed state. The floatation collar 2 giving it buoyancy. The draw ropes 4 have been released allows the weighted lead-rope 3 to sink pulling the draw ropes 4 through the series of rings mounted on the vertical plane 5. Figure 2 on page 2/3 being the side elevation of a fish cage 9 with its fish containment net 10 attached.
Figure 3 on page 2/3 is the side elevation of a fish cage 9 with its fish containment net 10 attached and the impermeable nonorganic membrane 1 partially encircling the fish containment net 10 as a curtain. The abrasion panel 8 can now be seen protecting the impermeable nonorganic membrane 1 and the floatation collar 2 from chaffing against the fish cage 9. Figure 4 on page 3/3 is the side elevation of a fish cage 9 with its fish containment net 10 attached and the impermeable nonorganic membrane 1 fully encircling the net as a curtain. This figure shows how the impermeable nonorganic membrane 1 overlaps prior to having the bottom of the fish containment net 10 fully enclosed.
Figure 5 on page 3/3 is the side elevation of a fish cage 9 with its fish containment net 10 attached and the impermeable nonorganic membrane 1 fully encircling the fish containment net 10. In this figure the lanyard 7 has been pulled tight through the bottom and end rings 6 fully enclosing the fish containment net. The chemical treatment to medicate the fish can now safely commence.
There is herein described a rapid deployment fish cage enclosure comprising of a floatation collar that keeps a packaged elongated concertinaed impermeable nonorganic membrane afloat and that can completely enclose the cages fish containment net within the water by way of releasing draw cords and tightening a lanyard.
The device, when deployed around a floating fish cage, can form a curtain from its packaged elongated concertinaed state by releasing draw ropes which allows its weighted lead-rope attached along the bottom of the impermeable nonorganic membrane to sink pulling the draw ropes through a series of rings that are mounted on the vertical plane of the impermeable nonorganic membrane. The device, from deployment in its curtain state, can form a total enclosure of a cages fish containment net within the water by pulling a lanyard through a series of rings mounted along the bottom and end of the impermeable nonorganic membrane which tightens the bottom of the impermeable nonorganic membrane and closes off the bottom of the fish containment net.
The rapid deployment fish cage enclosure device can also have an abrasion panel along its top to prevent chaffing of the floatation collar and the impermeable nonorganic membrane against the side of a fish cage.
The rapid deployment fish cage enclosure device can also be rapidly retrieved from the water by releasing a lanyard and allowing it to run through a series of rings mounted along the bottom and end of the impermeable nonorganic membrane thus forming a curtain from the total enclosure position.
The device can be rapidly retrieved from the water by pulling tight draw ropes which run through the series of rings that are mounted on the vertical plane of the impermeable nonorganic membrane causing the weighted lead-line to rise, thereby concertinaing the impermeable nonorganic membrane along the horizontal plane to form an elongated package.
