It’s hard to tell whether you have set a record if you don’t know what the old record was. It is even harder when you don’t know what your new claim is. But let us allow none of that to keep us from plunging recklessly forward because the implications are definitely worth cheering about.
But what was the previous record? That’s the first murky bit. It definitely sounds like it should be a record so I will call it a new record until someone proves it isn’t.
It does get a bit murkier, however. Some fishermen release their fish without tagging them, so calling the total “tag and release” isn’t exactly accurate if you think the “tag” part matters. And others release fish without telling us about it. Our weekly report is as good as we can possiblly make it but never really complete.
Why release without tagging? The release part is pure conservation of the species.
The no-tag part is a sign of frustration over the very low percentage of tags that are recovered. Re-captures hover around the 1% mark, which is good news or bad news depending on the low-recapture significance. On the good side, it may mean the marlin population is so huge that the chances of recapture are minimal. After all, with the great number of tags deployed here over the last weeks, months, and years, we might have expected one of those fish to be recaught right here.
On the bad side, it means the tags are being shed. Marlin might shed tags like you and I shed splinters.
On the even worse side, it could be that the fish are being recaptured by major commercial fishing operators who don’t want the recaptures to be known.
Against the odds of recapture, more fishermen are willing to put in the effort to tag, fill out the information card and send it to one of the data gathering agencies in hopes of doing something meaningful to the study of marlin habits and biology.
The 2014 Billfish Newslater of the Soutwest Fisheries Science Center (SWFSC) gives you a sense of the frurstration caused by the lack of recaptures.
You would think that with all of the problems plaguing traditional tagging methods, someone would have come up with a more effective way of gathering information about migration patterns and the ability of fish to survive fishing operations. In 2013, the most recent available year, only 3 blue marlin were recapture. Two of those were recaptured here in Hawaii and the third was tagged here.
The first was recaptured by Capt. Gene Vanderhoek after it had been at liberty for 36 days, SWFSC said. I was tagged her by Jack Leisher and Paul Cantor and ha travelled only 16 miles. Capt. Dave Bensko caught the other recapture here, but the release card was never returned. The chance for to learn about movement and time was lost. The third fish was tagged her by Sam Kossak and Chris Wong and then took off at a rapid rate. It was recaptured 885 nautical miles away after only 37 days.
Aha, they have. It’s the “PSAT,” the Pop-up Satelite Archival Tag. It’s a minature information-gatherin computer that attaches to the fish with a leash. After a programmed period, the leash is broken, the PSAT pops up to the surface and relays the data to a satellite and from there to a lab at Stanford University. The data includes a track showing where the fish has travelled during the time the tag was attached. The fact that it has moved a great distance tells that the fish has survived. The tracks themselves are remarkable for what they say about where the fish go and how fast they get there.
But don’t believe me. Visit http://greatmarlinrace.org and you will see the tracks of marlin tagged here over the last 6 years. The “Great Marlin Race” started here at the HIBT in 2009 and has now branched out to include competitions around the globe.
Tagging began here in Kona way back aroun 1970 when Capt. Jack Ross used a screwdriver to attach a protype traditional plastic “spaghetti tag” to a marlin and then released it. The fish and tag were never to be seen again but it was a start. Then scientist Heeny Yuen began poking around the Hawaiian International Billfish Tournament to encourage fishermen to help him in his efforts to get more tags in more fish. The effort expanded from then to know when we see the numbers posted here last week.
Right from the first, we were sending tagging information to the Southwest Fisheries Science Center in La Jolla, California. Back then, the few blue marlin tags from Hawaii were dwarfed by the huge mass of data being generated from tags of striped marlin in the Eastern Pacific. As the numbers grew here, the ratio began to reverse. By the year 2000, the SWFSC was getting more blue marlin tags from Hawaii than from anywhere else. Quietly, without a lot of fanfare, Hawaii has become the blue marlin tagging center of the Pacific.
If you don’t believe it, just look at the tagging numbers from last week, alone.
