- Oviduct transmitters were either ‘inserted’ into the body cavity via the oviduct or ‘implanted’ surgically just anterior to the genital pore. Values are the number of lake trout that reached each stage and percentages in parentheses are based on the number of lake trout that made it to the previous stage.
