Abstract
Laboratory growth studies and field work based on statoliths provide differing growth data for cephalopods. The goal of this study was to determine if visible implant elastomer (VIE) tags impact growth or mortality rates of Caribbean reef squid, Sepioteuthis sepioidea, Blainville. Five tanks with six tagged and six untagged squid in each were tested. There was no statistical difference in the growth rates between tagged and untagged squid in any of the treatments ( p > 0.35). Mortality was equal across all experiments. We found no evidence that the injection of VIE tags had an impact on the growth rate of S. sepioidea, making these tags applicable for studying the growth rates of individual wild squid. This technology should be used to compliment statolith work by allowing scientists to directly investigate size and temperature specific growth rates in free ranging cephalopods.
