To Tag a Shark

Shark, commonly known as flake, is a widely accepted seafood. It comes from several species of cold water shark.

But in the tropical waters north of Australia, there''s another shark fishing industry. Here, Taiwanese and Australian fishermen have been catching the Blacktip shark.

In order to establish sound management practices for developing this industry, CSIRO researchers from the Division of Fisheries have undertaken a series of cruises in Northern Australia to study the biology and reproductive behaviour of the Blacktip species.

Some one thousand sharks are caught and tagged on each cruise and much depends on the co-operation of Taiwanese and Australian fishermen in reporting the capture of tagged sharks.

Meanwhile food tasting experiments are looking at the acceptability of northern sharks to southern palates.

Produced in 1986.
