Cultivated Cod
Several growth trials were carried out with wild fish collected in Faxabay, e.g. to study how growth rate varied with temperature and how optimal temperature for growth varies with fish size. It was also studied how stocking density and maturity affected growth rate. There were also carried out some feed-, larval- and breeding studies.

Egg quality was studied with respect to size and age of females. Since 1994 a few thousand juveniles have been produced each year for research purposes. Rotifers and Artemia have been used as feed for the larvae. In the year 2002 about 25 000 cod juveniles were produced and most of them sold to three Icelandic companies. Many experiments have been carried out to study how optimal temperature for growth changes with fish size. The results have also been used to develop a mathematical model for food-unlimited growth rate of cod. Feed and immunological studies have also been carried out.

The main aim has been to introduce this valuable species to the mariculture industy in Iceland by obtaining a spawning stock and developing efficient larval production techniques. Only a few turbot are caught annually in Icelandic waters. The MRI has paid local fishermen a premium for live turbot to establish a viable spawning stock. A total of 1500, 10 000, 30 000, 25 000 and 130 000 juveniles were produced in years 1998, 1999, 2000, 2001 and 2002, respectively. Most of the juveniles have been sold to two Icelandic companies. Growth and survival has been good and a high price obtained for the fish, slaughtered at a weight of 2 kg. In the year 2002 yolksac larvae and live feed were also sold to one of the companies, resulting in additional 25 000 juveniles. A feasibility analysis of turbot farming in Iceland carried out by MRI gave positive results. Currently experiments are being carried out to study the relationship between growth rate and temperature for different sizes of fish.

In the year 1988 MRI carried out feeding trials of red abalone imported from California in cooperation with an Icelandic entrepreneur. A few years later the staff managed to produce several thousand juveniles. There are currently two companies in Iceland that cultivate red abalone. MRI has also participated in studies of optimal temperature and dry feed for abalone in cooperation with private companies.
