An inexpensive tag for short-term studies in milkfish (Chanos chanos Forsskal) and in seabass (Lates calcarifer Bloch)

Abstract

An opercular tag for marking adult milkfish (Chanos chanos Forsskal) and seabass (Lates calcarifer Bloch) is described. High tag retention and relatively low mortality rates were observed in adult fish handled two to ten times during 14-to 60-day tests. The features and advantages of the tag for marking large-sized fish in short-term studies are discussed.
