DAGENS TEKNIKKTODAY'S TECHNOLOGY
I dagens landbaserte oppdrettsanlegg er pumpehøyde,e11 er løftehøyde for den nødvendige vannti 1 før se 1,forbundet med store kostnader.Dette gjelder primært strømutgifter til drift.-Dagens metoder for å redusere disse kostnadene består i reduksjon i høyde på oppdrettskarene,samt tilføring av luft eller oksygen for å redusere vannmengden. Reduksjon i høyden på oppdrettskarene kan ofte virke negativt,både i forhold til investeringskostnadene og miljøet for fisken.Senking av bunnivå vil oftest medføre tildels kostbart undervannsarbeid,samt at sikring mot virkningen av oppdrift ved tapping av karene representerer et stort problem,som er kostbart å sikre seg mot. Tilsetting av luft/oksygen kan bare gjøres i begrenset måleståkk,av hensyn til opphoping av avfa 11stoffer ved redusert vannutskifting. In today's land-based farming facilities, the pump height, e11 is the lifting height for the necessary water 1 before see 1, is associated with large costs. This primarily applies to electricity costs for operation. - Today's methods for reducing these costs consist of reducing the height of the breeding vessels, as well as adding air or oxygen to reduce the amount of water. A reduction in the height of the breeding tanks can often have a negative effect, both in relation to the investment costs and the environment for the fish. Lowering the bottom level will often entail partly expensive underwater work, and that protection against the effect of buoyancy when draining the tanks represents a major problem, which is expensive to secure against. The addition of air/oxygen can only be done in limited quantities, due to the accumulation of waste substances in the case of reduced water exchange.
BESKRIVELSEDESCRIPTION
Tørrdokkbasert oppdrettsanlegg består i at en enten i fjell eller andre egnede grunnforhold etablerer en tørrdokk med bunn i det ønskede nivå,i forhold til utenforliggende sjø/vann.-Deretter plasseres oppdrettskarene i tørrdokken og tilknyttes rør fra sjø/vann(i nn 1øp-ut1øp kar). Overvann/lekasjevann pumpes ut av dokken enten kontinuerlig, eller når behovet er til stede ved eksempelvis tømming av oppdrettskar . Forøvr ig "v i ses'." t i 1 f i g . 1 i bilag 3 og til bilag 2. A dry dock-based breeding facility consists of establishing a dry dock either in the mountains or in other suitable ground conditions with a bottom at the desired level, in relation to the outside sea/water. vessels). Storm water/leakage water is pumped out of the dock either continuously, or when the need is present, for example when emptying breeding tanks. Instead of "see you." t i 1 f i g . 1 in appendix 3 and to appendix 2.
