Many countries whose fishing fleets catch large numbers of sharks have failed to meet a 10-year-old pledge on conserving the species, a report says.
The wildlife trade monitoring network Traffic and the Pew Environment Group say most of the main shark fishing nations do not manage fisheries well.
Ten years ago, governments agreed a global plan to conserve sharks.
An estimated 100 million sharks are killed each year, with nearly a third of species at risk of extinction.
Many fisheries target the fins for use in shark fin soup; and a number of countries, inclduing the US, have recently passed measures aimed at regulating the trade.
