In 2021, FISHBIO collaborated with Innovasea Systems Inc. to design and perform laboratory experiments to test the newest version of their smallest predation transmitter, the V3D As part of the study, largemouth bass (Micropterus salmoides) were fed a single rainbow trout (Oncorhynchus mykiss) tagged with a V3D tag each week for six weeks. Feeding trials were conducted at two temperature regimes (18.5 C and 23.5 C) to better understand the effect of temperature on tag performance. The tags activated faster in the warmer trials, with a median trigger time of 6 hours (compared to a median trigger time of 14 hours in the cooler trials), which was likely associated with faster metabolic processes. This study highlights the utility of this novel, commercially available technology, and provides context for future field efforts seeking to use these tags to directly measure the effect of predation in salmonid survival studies.
