Whale Sharks

Here is a picture of the tag from this year that came off after only a few weeks. This was the 3rd shark we tagged this year. We tagged it on 21 February and it came off on 3 March. As you can see if you look really carefully, you can see that about half the dart tip is sticking out.

I think we were having trouble with the pressure charge on the speargun about then which might explain why it didn’t penetrate deeply.   Brent had made notes in his log stating that he wasn’t sure that it was a good penetration, just from seeing how much of the tether was exposed when looking at it underwater.    In any event, it did stay on for about 2 weeks so we will get some data on movements and diving and of course a real plus on the recovery as we can use it again. 

Here are the GPS positions that helped us find it.
