The project Arctic Tilapia, which was funded by the Technology Development Fund, was recently completed and was joined by Mat\u00eds, Arctic Tilapia hf., Iceprotein hf. of Fisk-Seafood hf. The aim of the project was to develop products that make tilapia whitefish farming in a closed fish farm that utilizes cooling water from a large steam power plant economically in Iceland.<\/h4>\n\n\n\n

In order for this to happen, market channels for products must be available and secure.<\/p>\n\n\n\n

The technical objectives were, firstly, to develop a cooling and storage method for fresh fillets that maintains a light reddish tinge and fresh fillets, and secondly, to develop a processing method for salted products for the Spanish market.

Project manager was Emil\u00eda Martinsd\u00f3ttir, Mat\u00eds ohf.<\/p>\n\n\n\n

The aim of the project was to develop products that make tilapia whitefish farming in a closed fish farm that utilizes cooling water from a large steam power plant economically in Iceland. In order for this to happen, market channels for products must be available and secure.<\/p>\n\n\n\n

The technical objectives were, firstly, to develop a cooling and storage method for fresh fillets that maintains a light reddish tinge and fresh fillets, and secondly, to develop a processing method for salted products for the Spanish market. Nile tilapia (Oreochromis niloticus) was raised in a renewable water cycle system and filleted and packed in 100% air and aerated packages for storage at 1\u02daC and -1\u02daC. The results of sensory evaluation and microbial counts showed that fillets packed in air had a shelf life of 13-15 days at 1\u02daC and 20 days at -1\u02daC. In fillets in aerated packages, the total number of micro-organisms was very small after 27 days of storage at both 1\u02daC and -1\u02daC. However, aerobic conditions adversely affected the color of the fillets shortly after packing, but the color of the fillets significantly affected buyers' choices. The best storage conditions for tilapia fillets are packing in air and storage at a constant low temperature of -1 \u00b0 C. The effects of injection and pickling on the utilization, shelf life and properties of tilapia fillets were investigated. Three product categories were produced: chilled products, frozen products (with insignificant changes in salt content) and lightly salted, frozen products. Utilization increased during spraying and pickling, there was a significant difference in weight changes in frozen fillets and lightly salted fillets due to differences in the salt content of these two product categories.<\/p>\n\n\n\n

Tilapia from Canada and China were used in the first experiments of the project. Tilapiu farming began in Iceland at the beginning of the project period after an assessment had been made of the available stocks, as it is important to have a good breeding stock. A strain grown at North American Tilapia INC. Was selected. (NATI) in Canada. The experimental station was commissioned on 15 May 2008 when the juveniles arrived in Iceland. The juveniles had reached slaughter size in November 2008 and the fish was used for experiments after that. The results that the storage capacity could be achieved for up to 20 days at a consistently low temperature during storage and that there was no significant change in the red color on the carcass during filleting during that period give the possibility to ship the product as fresh, refrigerated fillets by ship to the European market. also to USA. In parallel with this research project, a great deal of work has been put into feasibility studies and work on business plans and communication with potential investors and partners in the marketing field. The business plan is being finalized.<\/p>\n\n\n\n
