POST-SMOLT FACILITY

Smolt is a salmon that has undergone smoltification. The smoltification process causes major physiological and morphological changes in the fish to enable it to tolerate life in saltwater. The fish is called post-smolt from the moment it is adapted to the sea and the first growth phase in the sea. Post-smolt facilities enable the fish to grow bigger, more robust and have shorter production time in the sea.
The first construction phase of Tytlandsvik Aqua was finished in 2019 and consists of two separate halls with a total of eight tanks and a production capacity of 3000 tonnes of large smolt for delivery to fish farmers. In the long term, the plan is to increase production capacity to 10,000 tonnes - adding four new halls with four tanks each. The water is extracted from wells and reused after being filtered for particles, purified for CO2, aerated and fed with new oxygen.

Tytlandsvik Aqua is built with recycling technology (RAS). All process equipment is provided by AKVA group.

"From the building was raised until biomass was introduced it took about 5 months. It was done in record time which we are very pleased with - considering the size of the plant," says Project Manager Troels Gade.

"We have developed some new solutions; a special lime system to adjust the pH value in the water, a salt system that can add salt to the water and a new type of FTC (Fish Tank Cleaner). In the process, we have also acquired useful knowledge in how to optimize both design, logistics and the procurement process for even smoother project execution," says Gade.

Tytlandsvik Aqua AS is located in Hjelmeland municipality in Rogaland, Norway, and is owned by Bremnes Seashore AS, Grieg Seafood Rogaland AS and Vesthavbruk AS with three equal parts.

Balance and design

The production unit design is imperative for a successful land based fish production facility, and the solution depends highly on the behavioral pattern of the species.
