Do not ever support the sale of shark fin soup

Many folks love thresher and mako sharks for eating. Check out a local fish market on pricing to confirm. You will also see them on the menu at many fish restaurants. Most are juveniles in the LJ area if I am not mistaken. I used to fish thresher out of Oceanside and average was 200+ with some going close to 400.

FWIW:

"Shark fins can fetch up to $650 USD per kilogram. A single Whale Shark pectoral fin can sell for up to $20,000 USD and a Basking Shark pectoral fin can fetch up to $50,000 USD."
http://www.sharktruth.com/learn/shark-finning/

"The majority of sharks caught for their fins are the blue sharks, threshers and hammerheads"
"Records from fisheries published in 2003 revealed that numbers of thresher sharks have fallen by 75% in just 15 years through overfishing."
http://www.theguardian.com/environme....frontpagenews

California ban on sale or possession of detached shark fins enacted in 2011 and went fully into effect in 2013.

Restaurants in violation of ban are being targeted

Appeals Court Dismisses Challenge to California Shark Fin Ban (July, 2015)

32 tons of shark fins seized at sea. This one 85' boatload of shark fins allegedly represents the death of 30,000 sharks.

My two cents. Threshers are good eating
Threshers are really really strong - don't fish for them alone
Threshers are dangerous to catch on a kayak even if you are prepared - watch out for the tail and the jump.
They get really big and there is little chance of bringing a big one in on a kayak - 200# I"m impressed. any bigger and you will be out there for hours and probably not get them.
If you can find a copy of Fred Archers Book on threshers, It's a great read. He also shows how to butcher them.

Selling any sport caught fish is illegal....

Lots of local research is being done on t-sharks.....

Sustainability Status/ Fishing Mortality

Based on analyses of productivity, CPUE, and catch data, fishing
mortality is estimated to be below the rate that would produce maximum sustainable yield; thus, overfishing is not occurring
(PFMC 2010)

Biomass is estimated to be above that required for maximum sustainable yield
and the stock is reportedly not overfished
(PFMC 2010)

Bycatch
Thresher sharks are taken incidentally in the swordfish DGN fishery.
Historically, there have been concerns about the level of bycatch of marine mammals and turtles in this fishery; however, after changes in fishing practices to minimize interactions with protected species, NMFS believes there is currently only a remote likelihood of incidental mortality or serious injury to marine mammals based upon the most recent information

www.nmfs.noaa.gov/pr/interactions/lof/

Common thresher sharks are also targeted by recreational anglers
(Heberer et al. 2010) The number of threshers caught annually by recreational anglers, including those released, is estimated from angler surveys and dockside interceptions.
Recreational catch varies widely from year to year but has averaged roughly 20 mt annually in recent years
www.pcouncil.org/bb/2008/1108/E3b_SUP_CDFG_1108.pdf
The estimated level of catch in this fishery may be imprecise because the fishery is patchy and sporadic.

This is my opinion.........

I am against the harvest of threshers on our stretch of coast south of PC. A lot of threshers I see harvested do not appear to be of the age/size of sexual maturity.

The info below on the subject of reproduction is something I have heard and read in the past from other sources.

"Thresher sharks are slow to mature; males reach sexual maturity between seven and 13 years of age and females between eight and 14 years in bigeye threshers. They may live for 20 years or more" (wikipedia.com).

People are gonna do what they want regardless of anyone's opinion. I'm sure it is a difficult trick to land one from a kayak, but You won't get any merit from me for doing so (not that is matters).

Shark fishing is kind of like cat-fishing. If you put food in front of them, they will eat it. They aren't like yellows or WSB where you can have days where you will have every bait in the tank/tackle box in front of them and they just won't go.

Have fun with them while they are here.

One of the coolest things I saw on my kayak was my mac getting tail slapped and then eaten by a nice sized thresher right underneath me as I was checking my bait. A very short battle then ensued as I promptly thumbed the spool to break him off. I have released or broken off all the sharks I have hooked. You guys can do as you please, it is not for me to judge. As a surfer, I always felt that if I don't mess with sharks, they won't mess with me.
