Abstract
A fish farming pen for rearing fish 1 with a physostome swim bladder includes fish pen walls 14 forming a confined submersible fish residence volume 12 adapted to allow the submersible fish residence area to be submerged below a sea surface 15. The fish 1 is prevented from accessing the sea surface 15. An air releasing bubble generating element 9 is located in or below the confined submersible fish residence volume 12. Furthermore, the invention relates to a method of rearing fish 1 with a physostome swim bladder in a submerged fish pen 6 without access to a natural sea surface. The method includes generating air bubbles at a lower part of the submerged fish pen 6, whereby the fish 1 with a physostome swim bladder is enabled to replenish air to their swim bladder from said air bubbles 5.
Claims (18)
1 . A fish farming pen for rearing fish (1 ) with a physostome swim bladder comprising: fish pen walls (14) forming a confined submersible fish residence volume (12) adapted to allow the submersible fish residence area to be submerged below a sea surface (15), whereby the fish (1 ) is prevented from accessing the sea surface (15); and an air releasing bubble generating element (9) adapted to provide bubbles to the confined submersible fish residence volume (12).
2. The fish farming pen of claim 1 , wherein the air releasing bubble generating element (9) is adapted to generate bubbles (5) with a diameter of at least 20mm when they reach the fish to allow the fish (1 ) with a physostome swim bladder to ingest air to its swim bladder.
3. The fish farming pen of claim 1 , wherein the air releasing bubble generating element (9) is adapted to generate bubbles with a diameter of at least 100mm when they reach the fish to allow the fish (1 ) with a physostome swim bladder to ingest air to its swim bladder.
4. The fish farming pen of any of the preceding claims, wherein the fish pen walls (14) forming a confined submersible fish residence volume (12) are formed as a cage allowing circulations of water.
5. The fish farming pen of any of claim 4, wherein the fish pen walls (14) include a separate, releasable net portion forming a separate physical barrier (10) preventing the fish (1 ) from accessing the sea surface.
6. The fish farming pen of claim 5, further including a releasable joint (13), securing the separate, releasable net portion forming the separate physical barrier
7. The fish farming pen of any of the preceding claims, wherein the air releasing bubble generating element (9) is adapted to be supplied with compressed air from an air source (8) through an air-line (7).
8. The fish farming pen of any of the preceding claims, further including an air dome (11 ) adapted to form an artificial water surface (16) below the sea surface (15).
9. The fish farming pen of any of the preceding claims, further including: a monitoring system (22) adapted to monitor parameters indicating if the swim bladders are sufficiently filled with air; a control unit (21 ) connected to the monitoring system (22); and an air source (8) controlled by the control unit (21 ), the air source (8) being connected to an air releasing bubble generating element (9) to generate bubbles (5) if the swim bladders are insufficiently filled with air.
10. The fish farming pen of claim 9, wherein the monitoring system (22) includes a camera monitor swimming speed and fish tilt when swimming and thus if the fish (1 ) requires air to their swim bladder if the fish (1 ) at least one of tilts and swims with their heads high and swims at a higher velocity.
11 . The fish farming pen of claim 9 wherein the monitoring system (22) includes an echosounder indicating if the swimming bladder is filled with air.
12. A method of rearing fish (1 ) with a physostome swim bladder in a submerged fish pen (6) without access to a natural sea surface comprising: generating air bubbles at a lower part of the submerged fish pen (6), whereby the fish (1 ) with a physostome swim bladder is enabled to replenish air to their swim bladder from said air bubbles.
13. The method of claim 12, wherein the air bubbles are generated not more than 1 ,5-3 hours a day.
14. The method of claim 12, further including: monitoring the fish with monitoring system (22) to monitor if the fish (1 ) requires air to their swim bladder; feeding information from the monitoring system to a control unit (21 ); and controlling an air source (8) connected an air releasing bubble generating element (9) to generate bubbles (5) if the monitoring system indicated that the fish (1 ) requires air.
15. The method of claim 14, further including generating bubbles (5) if the fish (1 ) at least one of tilts and swims with their heads high and swims at a higher velocity, and the monitoring system (22) includes a camera monitoring swimming speed and fish tilt when swimming.
16. The method of claim 14, further including: generating bubbles (5) if an echosounder indicate that the swimming bladders are insufficiently is filled with air, wherein the monitoring system (22) includes the echosounder indicating if the swimming bladder is filled with air.
17. The method of claim 12, wherein the method further includes the step of: intermittently providing a surface access in addition to the air bubbles for up to three days to make the salmon accustomed to interact with air-bubbles while air releasing bubble generating element (9) and creates air bubbles (5) in the lower part of a submerged farming pen (6), and where the specified amount of compressed air (7) is sufficient for the fish to learn to refill the swim bladder (4) at the same time as it prevents the fish from getting too little air by immersing the farming pen (6) without access to a natural water surface.
18. The method of claim 17, wherein the surface access is to an artificial water surface (16) formed in an air pocket (11 ) of a submerged farming pen (6).
