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

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

The estimated level of catch in this fishery may be imprecise because the fishery is patchy and sporadic.
