* The estimated release number is twice the actual number needed because previous work has shown that at least 50% mortality occurs when fish are not acclimated in pens at the release site for 3 days prior to release (Brennan et al. Unpublished data). An unknown additional post-release mortality occurs with the hatchery snook - - even with acclimation, and therefore, as a rule of thumb, 2x the actual number needed was released.
