our 
study had this 
issue, 
after its release is remarkably good. 
It is worth noting the negative buoyancy aspect of 
the tag harness rigging design. Musyl et al. (2015) 
emphasized the importance of testing for tag buoy¬ 
ancy with the tether and anchor mechanism attached; 
however, they found that most researchers failed to 
indicate whether these tests were conducted prior to 
future researchers should take note. It may also be 
necessary to consider whether some presumed mortali¬ 
ties in prior PSAT studies could actually have been in¬ 
stances when tags equipped with negatively buoyant 
harnesses were shed. 
No other estimates of release survival for bluefin
