Abstract
An arrangement and a method for treatment of fish, comprising a pipe (1) extending from an inlet (2) to an outlet (3), a supply of treatment liquid into an upstream section (1a) of said pipe (1). Said pipe (1) comprises a carbon dioxide aerator (14) downstream of said upstream section (1a).The pipe (1) may said upstream section (1a), an intermediate section (1c) and a downstream section (1b) where the upstream and downstream sections (1a, 1b) are elevated with respect to the intermediate section (1c). There may be a second supply of treatment liquid (15, 14d) immediately upstream of or into said carbon dioxide aerator (14). Some of the treatment liquid may be replaced during recirculation.
Claims (20)
1. An arrangement for treatment of fish, comprising a pipe (1 ) extending from an inlet (2) to an outlet (3); further comprising a supply of treatment liquid into an upstream section (1a) of said pipe (1), characterised in that said pipe (1) comprises an in-line carbon dioxide aerator (14) downstream of said upstream section (1a).
2. The arrangement of claim 1 , characterised in that the pipe (1 ) has said upstream section (1a), an intermediate section (1c) and a downstream section (1b), said intermediate section (1c) connecting said upstream and downstream sections (1a, 1b) and said upstream and downstream sections (1a, 1b) being elevated with respect to said intermediate section (1c), said supply of treatment liquid supplying liquid into said pipe (1) upstream of said intermediate section (1c).
3. The arrangement of claim 1 , characterised in that it comprises a counter-flow unit at a downstream end of the pipe (1 ).
4. The arrangement of claim 1 , 3 or 3, characterised in that the carbon dioxide aerator (14) comprises a walled structure (14a) attached to said pipe (1), said walled structure (14a) having an opening into the interior of said pipe (1) and an opening to the environment or to a suction unit.
5. The arrangement of claim 4, characterised in that the pipe (1 ) is perforated within the walled structure (14a).
6. The arrangement of any of the preceding claims, characterised in that the aerator comprises an air supply.
7. The arrangement of claim 4 and 6, characterised in that said air supply comprises an air duct (14b) with a fan (14c).
8. The arrangement of any of the preceding claims, characterised in that it comprises a second supply of treatment liquid (15, 14d) immediately upstream of or into said carbon dioxide aerator (14).
9. The arrangement of claim 8, characterised in that said second supply (15) is directed at an angle with the flow of treatment liquid in the pipe (1).
10. The arrangement of claim 4 and 8, characterised in that said second supply (14d) is into an upper part of said walled structure (14a) of said aerator (14).
11. The arrangement of claim 10, characterised in that said walled structure (14a) comprises a grate (14e) extending across the walled structure (14a) below said second water supply (14d).
12. The arrangement of any of the preceding claims, characterised in that the intermediate section (1c) of the pipe (1 ) has a length of at least 50 meters.
13. The arrangement of any of the preceding claims, characterised in that it has an outlet (12) for waste treatment liquid and an inlet (13) for replacement treatment liquid.
14. A method of treatment of fish, where the fish is conveyed through a pipe (1 ) together with a treatment liquid, where said treatment liquid is supplied into said pipe at a first location along said pipe (1), characterised in that carbon dioxide is aerated from said pipe (1) at a second location downstream from said first location.
15. The method of claim 14, characterised in that additional treatment liquid is supplied into said pipe immediately upstream of or at said second location .
16. The method of claims 14 or 15, characterised in that a portion of the treatment liquid is continuously replaced.
17. The method of claim 16, characterised in that at least 15 % of the treatment liquid is replaced per hour of operation.
18. The method of any of the claims 14-17, characterised in that said treatment liquid is warm water having a temperature of 28-34°C when it is supplied.
19. The method of any of the claims 14-18, characterised in that oxygen is supplied into the treatment liquid.
20. The method of any of the claims 14-19, characterised in that the fish is rinsed with seawater downstream of said pipe (1).
