Makos in the north, baby Blue Sharks in the South. That’s part of the pattern we’re seeing.
The Mako—a tough customer—got outfitted with the two kinds of electronic tags, as I described earlier in the trip. The combined price of the two tags is $5,500 per shark. It’s a commitment to science that must not be wasted when it comes time to use the information to manage fisheries.
This morning’s breathless dawn found us in a slick molten-looking sea 40 miles off San Diego. The overcast that had broken yesterday returned; turning the water slate gray under a dense ceiling.
Whales and dolphins have kept us in good company all week. While we were setting this morning a pod of big, blunt-headed, high-finned Risso’s Dolphins followed a Minke Whale’s appearance. The afternoon brought Short-beaked Common Dolphins.
We’ve moved south of most Makos and are into water where swim the tiniest Blue Sharks I’ve ever seen. Many of our hooks came back bare or with bait bitten in half, apparently from sharks too small to get hooked. The 21 sharks we caught were mainly less than three feet. And though we lost the largest Blue of the trip—nearly nine feet long—we also caught perhaps the smallest Blue Shark of this tagging project: less than two feet from nose to tip of tail—virtually newborn.
In all we tagged 21 Blue Sharks today.
