Star-Oddi is introducing the world's smallest DST measuring  temperature and depth. The tag is named DST micro. Its size in Diameter is only 8,3 mm and length 25,4 mm, weighing 1,9 gram in water. The product has been available in Star-Oddi development department for more than one year, but with recently made contracts for tagging salmon smolt, the tag is being transferred into volume production. Besides being used for tagging juvenile fish, on species that have already been tagged, the tag will also be used for tagging species that have not been possible to tag previously, due to small size of the fish. The tag will be available for delivery in spring 2005.
Please see more information on the tag.
In May 2004 the Marine Research Institute in Iceland was the first institute in the world to take into use the pioneering DST GPS fish positioning system made be Star-Oddi and Simrad. For the last few months some of the tagged cods have been recaptured and three of them had recorded GPS code sent from a research vessel carrying a Simrad sonar. The cods that carried the three tags provide invaluable information about the fish migration pattern and the fish behavior, information that is not possible to obtain by other means for reasonable cost. The DST GPS tags store information about the fish GPS position that is sent from a vessel in parallel with temperature and depth.
The picture shows the recaptured GPS tags that had received a GPS code sent from a research vessel that transmitted the code with a Simrad sonar. The three tags are displayed with different color, and with date.
More information about the GPS system.
In October 2003 the Marine Research Institute of Iceland tagged approximately 200 redfish at depth of 500 m with the Underwater Tagging Equipment (UTE) made by Star-Oddi. Today, one year later, altogether ten (10) fish have been recaptured from this cruise. The last three recaptures provide very valuable information about the migration pattern of redfish in Icelandic territorial waters.
The redfish were tagged SW of Iceland on the Reykjanes ridge in October 2003 but two were recaptured in mid August 2004 after carrying a tag for 10 months and the last one was recaptured few days ago after carrying the tag for twelve months . A fishery boat named Sunbeam from Shetlands Islands (UK) recaptured two tagged redfish on fishing grounds east of Iceland, specifically on the western slope of the Iceland - Faeroe Islands ridge, approximately 180 nautical miles from the release site last august and the last one was recaptured by an Icelandic fishing boat west of Iceland.
This behavior is especially valuable where it proves that the redfish wanders around Icelandic territorial waters. This information helps the scientist to understand the migration behavior pattern of the redfish, and ultimately help the institution to accomplish one of its goals; to improve sustainable management of the redfish stock.
