In the period from week 45, 2007 to week 3, 2008, 52 reception controls have been carried out at the time of delivery of salmon eggs to the Norwegian market. This adds up to control of 86 % of a total of 98 million eggs sold so far. There has been an average of 1.34 % non-viable eggs in the deliveries which were controlled, of which 0.77 % were small-eyed eggs.
AquaGen provides ongoing information to subscribers about the status of salmon- and trout egg production through the publication of AquaGen EGG UPDATE.
The eggs which are produced are a result of breeding and genetics, and also of the production of brood fish which has begun 3-4 years before. In the course of this period the brood fish are managed so that the client receives eggs at the agreed-upon time, with the proper quality and quantity.

The point in time for hatching of salmon eggs is often calculated to occur at 500 day-degrees after fertilization. This applies if the eggs have been incubated at between 6 and 8°C. However, in the course of a normal production cycle eggs are often stored at controlled temperatures of less than 6°C. This is sometimes necessary to deliver eggs according to the customers required point in time.
We wish to collect data from all egg deliveries on hatching success, yolk sac- and start feeding phases. In this way we can gain knowledge about our the performance of our product under different commercial conditions and the factors which are important for survival, growth, and quality.
The final stripping day for the production of late eggs was at Aqua Gen Tingvoll on 11th Feb 2008. These eggs will be delivered at the end of May, 2008, this delivery date represents an extension of the season by about one month in comparison to last year.
This year’s start feeding for fry from the earliest deliveries is in full swing. Reports so far have been very positive. Facilities which have reported the most successful start feeding have used a rapid temperature rise from 8-9 °C to 12-14 °C over a 3-4 day period.
