People fishing in the Bay of Islands are being asked to keep a look out for a young hammerhead shark, nicknamed Orokawa. <\/p>\n
Orokawa is providing scientists with information on his whereabouts after becoming the first electronically tagged hammerhead to provide useful data in New Zealand waters. <\/p>\n
The young shark, just 137cm long, was tagged last Sunday near Deep Water Cove in the Bay of Islands by fisherman Scott Tindale. <\/p>\n
\"We were anchored within casting distance of the rocks and saw a hammerhead swimming towards us on the surface,\" Mr Tindale said. <\/p>\n
\"I cast a bait towards him and he took it straight away. Because he was small we were able to get him in the boat, oxygenate his gills with seawater from a deck hose, and tag and release him within five minutes.\" <\/p>\n
NIWA shark expert Dr Malcolm Francis has been contracted by the Ministry for Primary Industries to find out more about the biology, behaviour and stock status of hammerhead sharks in a bid to determine whether they are threatened by overfishing. <\/p>\n
Dr Francis and Mr Tindale plan to tag a number of hammerheads - recognisable by their bizarre head shape - in the coming year to determine whether they are resident or migratory and what they do. <\/p>\n
Little is known about the species, its habitat or abundance in New Zealand and Dr Francis says the young hammerheads are vulnerable to capture by set nets, longlines and trawls. <\/p>\n
\"They seem to be very sensitive to capture and most of them die before they can be ret <\/p>\n
urned to the sea.\" <\/p>\n
