On Independence Day 2016 the Tag team aboard the Shogun actually made some real history. We have struggled to learn how to capture tag and release the largest Pacific bluefin tuna we have seen in our lifetime and this day proved more successful then the previous two. Today aboard the shogun, a long range recreational fishing boat out of San Diego we were able to catch three Pacific bluefin that taped twice on two fish to 184 cm (72-73 inch fish) above the 200 lb class of Pacific bluefin and get them to the swim step. Two of the three fish were in excellent condition for double tagging with pop up satellite archival tags and an implantable archival tag went in surgically in both. The tasks were challenging for the team from the hook up on a kite with a surface bait to the fight on heavy stand up tackle in the open ocean.The coordination and capacity for our team to capture in a sling and lift a large fish and the water draining from the sling to the deck for tagging. Led by Robbie Schallert of TAG and Dr Luke Gardner of Stanford the men with help from many others were able to place the large fish in a sling and move it to the deck placed Mats for tagging. Pacific bluefin older the six years of age hold a secret we want to know: Where and when do they breed in the Pacific. The excitement aboard the Shogun is that this is a challenging operation and we are succeeding and improving daily. Five of these large fish have been hooked successfully and three to date tagged and one sampled intensively. These fish hold a secret to he life history of bluefin we all seek to understand. This tagging trip working out the techniques to handle large bluefin for this realm reminds me of our work over twenty years ago off North Carolina in 1996 when a small team from the TRCC went out with Captain Bob Eakes to figure out how to tag and release this similar class of fish on the east coast. From the 1996 work we went on to tag 1300 Atlantic bluefin most bigger then the fish we are working on today. Our goal as we go forward is to satellite tag the larger bluefin we can catch in the Pacific but it's very hard to access these large fish.
But confidence grows from catching three and releasing two large Pacific bluefin on the fourth of July and we are all excited about what we are seeing. The fish are packed full of red tuna crabs and anchovy. More bait and whales and Albatross and shearwaters making a hot spot on tthis region of our blue Serengeti of the California Current.
