Whether the fish is marketed fresh at 1,5 – 2,5 kg, or even larger specimens are produced for smoking purposes, or live fish for stocking of fishing ponds etc., large, well pigmented rainbow trout produced in freshwater is a valuable cost effective supplement to the more traditional freshwater product: pan size rainbow trout.
Depending on general farming conditions and temperature range in particular, the production of large rainbow trout in freshwater may require more than two winter periods. To reduce the risk of pre-slaughter maturation, AquaSearch ova is offering all female eggs from 4 or 5 year old maturing brood stock.

Because of the genetic correlation between late maturation and low specific growth rate (SGR) it is a delicate balance to breed for high growth rate and late maturation, but with AquaSearch LATE, we are offering “the best of both worlds”.
4 or 5 year or older maturing brood stock are used
General stress and disease tolerance
High growth rate
Low feed conversion rate
Elongated body shape
Aggressive feeding in fry as well as on-growers
Depending on feeding rate and local conditions, maturation during the period required for production of large rainbow trout should not be an issue.
*Provided hatching technique and environmental conditons are not compromising in any way.

The production of large, well-pigmented rainbow trout!
Becoming more and more a valuable cost effective supplement to the traditional pan-size, whatever the fish is to be used for smoking purposes or for stocking in fish ponds.
Growing the large trout requires more than 2 winters without the setback of maturation. The AquaSearch LATE is based on offspring from 4 or 5 year old first time maturing broodstock.
Along with the family based selection, AquaSearch ova ApS is also carrying out an implementation of genetic and genomic selection. This type of selection is more precise and allows for selection on hidden traits such as resistanceagainst specific diseases.
