The
National Institute of Water and Atmospheric Research (NIWA) is conducting
research on the West Coast to determine how strong snapper stocks are. The
research is being conducted to determine if “rebuild measures” that were
implemented after the last count 10 years have worked.
The tags
have been inserted into the guts of 27,000 snapper. The tags are around 10mm
long and 3mm wide and NIWA promise the wound heals quickly and the device causes
no harm if digested by people or pets.
The snapper
were caught in successive trawls taking around 200 at a time. The fish were then
held in tanks and were later tagged and released
