Fishing for science: Tagging and studying sailfish and marlin habits

I recently helped a group of scientists, led by Dr. Larry Crowder from the Hopkins Marine Station at Stanford University, catch fish to better understand and manage ocean pelagics like sailfish and marlin.

It was a good day for fishing and science. There was enough fish for the scientists to be selective with the ones they tagged. They placed satellite tags in three marlin and nine sailfish They chose the healthiest looking fish to place the tags. The tags cost around $4,000 a piece, so it pays to be careful. The tags they use have a “double loop” system which limits the drag in the water and keeps the tag close to the body. It’s black so predator fish won’t be attracted to it. . . .
