Description
Denne oppfinnelse vedrører en fremgangsmåte ved fremstilling av f6r for f6ring av fisk i saltvann. This invention relates to a method for the production of feed for feeding fish in salt water.
Det er særlig to f6rtyper som er blitt brukt hittil. There are two types of fire in particular that have been used so far.
Den ene typen, såkalt våtf6r, består av finmalt fersk eller frosset fisk som tilsettes vitaminer og bindemiddel, og som blandes til en grøt som kastes ut til fisk i oppdrett. One type, so-called wet feed, consists of finely ground fresh or frozen fish to which vitamins and binders are added, and which is mixed into a porridge that is thrown out to fish in farming.
Den andre typen, såkalt tørrf6r, består av finmalt kraft-f6r som er presset sammen til faste pellets, som kastes ut til fisk i oppdrett. The second type, so-called dry feed, consists of finely ground kraft feed that has been pressed together into solid pellets, which are thrown out to fish in farming.
En ulempe ved bruk av våtf6r, som inneholder 25 - 35 % tørrstoff og 65 - 75 % vann, er at det må tilføres relativt store volummengder for å dekke fiskens næringsbehov. Våtf6r-behovet er ofte så stort at det er vanskelig å få tilført de nødvendige mengder næringsstoffer som skal til for en optimal vekst og utvikling på grunn av den store lagerkapasitet som kreves. En annen ulempe ved bruk av våtf6r er den sammenfrys-ing som lett vil skje om vinteren. Om sommeren er ulempen med våtf6r forspill som skyldes oppsmuldring. A disadvantage of using wet food, which contains 25 - 35% dry matter and 65 - 75% water, is that relatively large volumes must be added to meet the fish's nutritional needs. The moisture requirement is often so great that it is difficult to supply the necessary quantities of nutrients required for optimal growth and development due to the large storage capacity required. Another disadvantage of using wet fodder is the freezing that will easily occur in winter. In the summer, the disadvantage of wet feed is pre-spill due to crumbling.
Ulempen ved bruk av tørrf6r er at dette ikke inneholder vann. Fisken må derfor dekke sitt ferskvannsbehov ved å av-spalte saltvann som den drikker. Denne fysiologiske prosess fungerer bra ved vanntemperaturer over ca 10 grader Celcius, The disadvantage of using dry fodder is that it does not contain water. The fish must therefore meet its fresh water needs by breaking down the salt water it drinks. This physiological process works well at water temperatures above about 10 degrees Celcius,
men den fungerer gradvis mindre bra ved lavere temperaturer. Følgen av denne fysiologiske prosess er at fiskens vekst og utvikling vil hemmes gradvis i takt med synkende vanntemperatur siden denne diettypen ikke inneholder ferskvann. but it works progressively less well at lower temperatures. The consequence of this physiological process is that the fish's growth and development will be inhibited gradually as the water temperature drops, since this type of diet does not contain fresh water.
Oppfinnelsen har til formål å eliminere de ulemper som The purpose of the invention is to eliminate the disadvantages which
er nevnt ovenfor. are mentioned above.
Formålet oppnås i henhold til oppfinnelsen ved en fremgangsmåte hvorved det til en ferdig f6rblanding i melform, som er tilsatt et vegetabilsk og/eller animalsk bindemiddel, under omrøring i en f6rblander blir tilsatt 60 - 80 % ferskvann når sjøtemperaturen er mindre enn 5° Celcius, 40 - 60 % ferskvann når sjøtemperaturen er mellom 10°og 5° Celcius og mindre enn 40 % ferskvann når sjøtemperaturen er over 10° Celcius. The purpose is achieved according to the invention by a method by which 60 - 80% fresh water is added to a ready-made premix in flour form, to which a vegetable and/or animal binder has been added, while stirring in a premixer when the sea temperature is less than 5° Celcius, 40 - 60% fresh water when the sea temperature is between 10° and 5° Celcius and less than 40% fresh water when the sea temperature is above 10° Celcius.
For at blandingen skal få en hensiktsmessig størrelse og form, kan den presses gjennom en vanlig f6rkvern med passende hullskive, og hvor en utvendig roterende kniv kapper f6ret i passende lengder, såkalte pellets. In order for the mixture to have an appropriate size and shape, it can be pressed through a regular square grinder with a suitable perforated disc, and where an external rotating knife cuts the wood into suitable lengths, so-called pellets.
Ved bruk av denne oppfinnelsen vil fiskeoppdretteren ved å avlese oppdrettvannets temperatur kunne produsere pellets med By using this invention, the fish breeder will be able to produce pellets by reading the temperature of the breeding water
riktig ferskvannsinnhold, noe som vil gi en optimal vekst og utvikling ved forskjellige vanntemperaturer. I forhold til våtf6r, som er den i dag anvendte f6rtype ved lave vanntemperaturer, vil en f6rtype i henhold til oppfinnelsen også redusere utgiftene til transport, lagring og utf6ring. correct fresh water content, which will give optimal growth and development at different water temperatures. In relation to wet fodder, which is the currently used fodder type at low water temperatures, a fodder type according to the invention will also reduce the costs of transport, storage and handling.
