Factors influencing mortality estimates in post-release survival studies
Campana et al. (2009; Mar Ecol Prog Ser 387:241-253) explored the survival Of blue sharks Prionace glauca captured and released from the North Atlantic commercial longline fishery. We think that their comments and comparisons do not accurately reflect a previous survival study of blue sharks in Hawa...
