Uncooperative Salmon Slam Taggers

Barb Block, salmon-tagging in Alaska. Well, yesterday was not the day we shark taggers dream of. It was the day that reminds me why few have done this work before. It was a bit cooler and rained heavily all morning. I lost the sharks I hooked. We had been given some large silver salmon to entice them and it was tough to keep the salmon sharks on the gear. Eventually, we got in a groove, hooked some sharks from the skiff, which we use to get closer to shore, and brought them to the R/V Solstice for tagging.

By mid-day, Dawn Treader with Captain Dave Pope and his wife, Diane, transferred a salmon shark to a research vessel for tagging. A second transfer came from a group of men who were trying to set a light tackle record.

Later, we had a batch of fish that in every way tested the research team. Some just said no to tagging by escaping from our stretcher just before we brought them into the tagging station. Others fought hard once they were in the tagging station. We irrigated all the sharks with sea water so that they could keep breathing, and with some persistence into the evening, tagged 6 sharks. Two of those we put all three types of tags on.

So far, we've tagged 14 sharks. It's hard to describe the precision it takes with a team to do this. If it were not for TOPP's Stanford graduate students Chris Perle and shark soother Aaron Carlise; Dan Madigan and associates Alessandro and Mike; and Dr. Joe Bonaventura, this could not be done!

We've got one more day to go. Last night, the members of the tagging team were literally licking their wounds. Lots of broken skin from handling big sharks. Maybe the record runs of pink salmon are filling up these fish, because they're larger than we've handled before.

Salmon shark identification

Barbara recently helped NOAA Alaska Sea Grant and scientists at the NOAA Alaska Fisheries Science Center track down photographs of sharks to use in a new, first-ever field guide to Alaska sharks, skates, and ratfish. The book is authored by NOAA's Duane Stevenson, Gerald Hoff, and James Orr, with John McEachran of Texas A&M University. The water-resistent book includes color photos and keys to identification of nine shark, 15 skate, and one ratfish species known to occur in Alaska waters. Well-known Alaska fish artist, Ray Troll, created original art for the cover. More information about the field guide is at: http://seagrant.uaf.edu/bookstore/pubs/SG-ED-57.html
