Nr. 3 / August 2016
The first sea-reared broodfish that comprise the origin of a new generation of salmon eggs have been stripped at AquaGen. This is a generation better adapted to the challenges currently facing the industry, and eggs will be ready for delivery from the beginning of October 2016.
More mature broodfish early
From broodfish that have lived their whole lifecycle on land, there has been a successful and closely controlled production of so called “off season” eggs with great results. Approximately 20 million eggs will be delivered in the third quarter to farmers in Norway and Scotland from this production.
While “off season” eggs are transported to the hatcheries, the traditional early egg production of 2016/2017 season eggs has begun. Stripping of the first broodfish reared in the sea was conducted on 22nd August 2016 at both AquaGen Hemne and AquaGen Steigen (Figure 1). Stripping happened at around the same time as last season, however, this year more mature fish at both sites have been reported. This will produce greater amounts of eggs that can be delivered as early as week 41 and, as a result, AquaGen will be able to deliver eggs all year round from Norwegian broodstock sites (Figure 2). Increased flexibility and improved utilization of capacity in smolt production will be possible, at the same time as that optimal production of early S0 and large smolt will no longer be limited by the availability of eggs.
Production of large smolt
In order to have the best starting point for production of large smolt, it is an advantage to take in the eggs early. A large smolt with high growth potential will lead to a significantly reduced production time in the sea. Fast growth in both freshwater and seawater is generally strongly emphasized in the whole of AquaGen’s breeding material this season too. This very best genetic material that AquaGen offers combines these attributes with selection for lice resistance and handling tolerance.
Beginning this season, AquaGen’s product portfolio has developed with new, more sophisticated products that are adapted to the challenges facing the industry today. This places greater demands for the planning and logistics process connected to the testing and selection of broodfish, together with the production and distribution of eggs. We produce eggs to order and it takes a minimum of 7 weeks from the eggs are being fertilized until they are ready to be dispatched. To accommodate the egg orders in terms of quality, quantity and delivery time, we urge our customers to place the orders as early as possible and at the latest 10 weeks before desired delivery.
