How to Tag a Redfish

Tagging redfish is an important piece of the puzzle providing information to marine biologists out of Iceland. From traditional to advanced methods, tagging has evolved over the years by equipping the fish with an electronic data-storage tag. These tracking tags help researchers study the behavior of redfish and the crucial role the fish have in our deepwater ecosystem.



Successful tagging encouraged the biologists from Iceland to consider tagging other deepwater fish. Information about specific species, migration and reproduction would be a valuable resource to declining populations.

      Catching the fish manually takes patience and a stealthy approach since redfish frighten easily in shallow or clear water. Redfish can be found near areas where an abundance of mollusks, crustaceans and small fish find shelter in shallow waters. When high tide recedes, redfish are close by feeding on shrimp and small crabs. Redfish weights vary between 40 to 90 lbs. Shrimp and small fish, such as pinfish, are excellent bait to catch a redfish. If using live bait does not appeal to you there is a variety of artificial lures available to entice redfish. Once you feel that nibble at the end of your fishing line -- reel it in. Using a net will ensure the redfish does not break free off the hook and get away.

      Place the redfish on a measuring board keeping a firm hold. A pair of pliers will efficiently remove the hook from the mouth. Lay the fish on its side. With a scalpel, carefully cut a ¼-inch incision along the abdomen area so no internal organs are touched or damaged. Insert the streamer tag. The incision will quickly heal in 2 to 3 days, and then the redfish is released back into the water.

      Scientists or researchers control tagging programs, however, any angler can play an important role in the research of redfish by returning tags and information about the status of the captured fish. The information provided helps with movement patterns, mortality rates and future fish populations.
