Well, I think this coffee has done away with my caffeine habit. I’m down to a half cup diluted with water and that is only because I needed to wake up. I’ve noticed that most of the people on this ship are tea drinkers. Now, I know why.
our shark
Our watch began with sailing to the next plankton station. A squall began, so it was time to get my raingear on. During the squall birds seemed to be attracted to the ship. Toward the end of the storm a little warbler landed on deck. He kept trying to find a place to land away from people. Finally, he was so tired, he landed at my feet. After a few seconds he flew to the edge of the stern. He contently waited out the storm there.
I asked Laurie, one of the marine biologists if she had any ideas on why the birds were following us. Apparently, there was a birder on the last trip that explained because we are close to shore (one of my favorite spots, Corpus Christi) the insect were attracted to our lights and the birds are attracted to the insects.
Again we had problems with the plankton tow. After they got the equipment fixed another squall started and the deployment of the equipment was delayed, once again, until the end of the storm.
Taking Samples
We finally got to the Shark Station. Not too exciting tonight. We only caught two dogfish sharks. I didn’t even take pictures because it paled to what we have all ready done.
We are at the last Shark Station for our watch. I guess we saved the best for last. Hook number 82 gave an 16 foot Sand Shark,. Too big to be brought on deck, she was measured and weighed in her basket. Tissue samples were taken and she was tagged before we let her go. Exciting!!!!

As we started our watch we were on our way to the next Shark Station. The other shift had already baited the hooks, so all we could do was wait. Before lone we were deploying our hooks, but the real excitement began when we started pulling in fish. Our first two fish were Gaff Top Tailed Catfish. These very ugly fish are one of the only saltwater catfish species.
Rainbow
We started to pull in Black Tip Reef sharks, followed by a Stingray. The end was the most exciting. The crew pulled in the top half of a Black Tip shark following right behind was a very large Bull Shark. He was so large that he bent the hook and was able to free himself.
We are just off South Padre Island Texas because we can see the lights from the town. Hey, Spring Breakers that come here…this is where we pulled out Black Tip Reef Sharks, a Bull Shark and half of a Black Tip. Enjoy!
Sunrise
During wait time this evening I have been trying to edit my blog. The internet is very sporadic, it will go down in the middle of loading pictures, On some days I can only get text and on other just pictures. I think I have it fixed but I’ll check it again later.
God has really been putting on a show. First, the fireworks, the sky was just lit up with beautiful flashes of lightening. Just after a fabulous sunrise, He placed a rainbow over our stern.
Gaff Top Tailed Catfish
Our last run was fantastic, catching 25 sharks. Two of them were large Hammerheads as well as, numerous Black Nose and Black Tip. At times there were three sharks waiting on deck to be measured and weighed. The last thing we do before our shift ends is bait and drop the hooks for the next shift.

Groupers
My biorhythm clock has been reset; I didn’t wake up until my alarm rang at 11:00pmWhat an exciting start to the shift. The day shift caught nothing all day. Within a few minutes of our arrival the fish just kept coming. There were so many that the day shift stayed on to help us measure, weigh, and tag the sharks before we returned them to the sea.. Besides the sharks we also caught a large red snapper.
measuring a shark
Next Cassidy and I helped out with the bongos. These are twin plankton tows that stay at a certain angle based on controlling the angle of the line. The depth is determined by the amount of line that is let out. The first time we got the baskets a little too deep in the water. So we brought up two containers of mud. We rinsed out all the mud and tried again. This time we were successful. Cassidy and I rinsed the baskets into sieves and washed down the plankton before putting it in specimen jarsWe then proceeded to bait one hundred more hooks and once again began out quest for sharks. After dropping the line and waiting an hour we were ready to pull in more sharks. I .worked the computer for this catch The computer logs in the exact location of each fish caught We caught NO sharks this time. We did catch three huge Groupers.I intended to watch the sun rise but it was behind a cloud bank. We had an hour before our next station, so we had breakfast. I’d like to give a big thanks to our cooks. You can have pretty much what you want for breakfast made to order
We arrive at the next station at 8:00am. It is another plankton tow, but this time we caught a moon jelly. It takes up about an hour then on to our next station, sharks! Unfortunately, its going to take us two hours to get there. I don’t think our shift will have the opportunity to land the sharks.

Me, tagging the shark
Finally, my first taste of shark.! My shift started at midnight. We baited 100 large hooks with mackerel. Then at a precise location the hooks were released one by one on a long line. The hooks were left in the water for one hour. Then the hooks were pulled out in the same order they were put in the water.
My first shark
We cleaned up everything because it is really good to wash fish slime off before it smells too bad. After our shark adventure, we did another plankton tow. This time we collected pounds of sea grass. A piece of discarded plastic about the size of a Frisbee blocked the plankton shoot so that grass accumulated.
We arrived at our next site and once again baited 100 hooks, released them and waited an hour. Our luck was a little better this time. We got two large sharks, one of which I got to tag, a couple small ones and a remora.
