GEORGE TOWN, Cayman Islands -- Scientists in the Cayman Islands are conducting a census of stingrays at a popular tourist spot to determine if their numbers are still declining.
Previous censuses at Grand Cayman's North Sound found that the number of southern stingrays had dropped by about 40 per cent in recent years. It is unclear why the numbers are diminishing.
An average of 100 stingrays were reported from 2002 to 2008.
Officials with a local dolphinarium released six stingrays into the North Sound on Friday following an amendment to a marine conservation law aimed at further protecting stingrays.
