What is the potential for severely traumatized cetaceans to survive
at sea? The question has been asked specifically about animals and
groups released after strandings and entanglements, but here is
directed to animals subjected to capture in shallow water, and
released after other individuals in the group have been killed under
permit. The question is relevant to meeting permit requirements
where certain species are not to be killed: If they are captured
with permitted species, subjected to the trauma and released will
they survive or die?
On 13 November 20 Risso's dolphins, Grampus griseus, and two
rough toothed dolphins, Steno bredanensis, were driven out
to sea after a nine-hour period where a still-unknown number of
Risso's dolphins of the mixed group were killed and processed in a
bay at Taiji, Japan. This is a request for data from any source
relating to the potential survival of the released cetaceans,
specifically trauma-induced responses known to affect the potential
for the group or the individuals to survive.
