 branchs in activity. 



2. Physiological traumas associated with capture and confinement. 



These are not distinct in their overall effects, but each is associated with a 

 somewhat different complex of factors. 



Sharks that struggle on a longline for a time often fail to survive for more 

 than a few hours, even with minimal blood loss and tissue damage sustained
