Developments in Fish Culture: Enhanced Diffusion of Calcein into Rainbow Trout211 Fry Using Cavitation Level Ultrasound

摘要

Enhanced diffusion of calcein into rainbow trout, Oncorhynchus mykiss, fry was211u001eachieved using cavitation level ultrasound for the purpose of mass marking. Three 211u001evariables, consisting of two voltage amplitudes, two calcein concentrations, and 211u001etwo treatment durations were examined. Overall mean diffusion of calcein ranged 211u001efrom 0.4 to 36.6 ng/fish. Highest absorption level was achieved when highest 211u001eamplitude, 120mV was applied for 15 min in 900 mg/1 of calcein solution. The 211u001eleast amount of diffusion resulted from 90 mV for 5 min in 600 mg/1 solution.
