It’s great that lots of people use Porirua Harbour for different activities, but I’m starting to get a little frustrated as I’ve had one of my routers knocked over by a yachtie, one of my tracking tags stolen by a water-skier, and now a fisher has caught one of my tagged sharks!

I’m guessing that there are between several hundred to several thousand rig sharks in Porirua Harbour during the spring and summer, so what are the chances that the ONE I have tagged gets caught? I’ll do some simple math for you it’s between 0.00002% and 0.000005%, that’s a pretty low.

What made it even more unlikely was that I was talking to the fishers at the time, telling them about my research, and if they ever caught one of my tagged sharks could they please return the tag to me. Then one of them caught my rig shark.
