摘要: Abstract Recent studies have demonstrated the feasibility of using passive integrated transponder (PIT) tags for tracking crayfish spatiotemporally in streams. PIT can be inserted internally long-term tracking, assuming low tagging mortality, or attached externally shorter-term until individual molts. To date, practical use internal cephalothorax has been limited to individuals >30 mm carapace length (CL). The efficacy small-bodied species juveniles large-bodied remains poorly understood. We conducted with Orconectes compressus (Slender Crayfish) assess whether placement small (8.5 long, 2.12 diameter) was a viable methodology future ecological work. In field, we tagged 63 and monitored them portable transceiver system 1.5 weeks. laboratory, 21 maintained control 12 Crayfish averaged 1...
