And do you suspect HSB are still in your pond or you think somehow they died in the 'kill' event? . Nate and I discussed that. His experience is HSB are not very tolerant of low oxygen sats, so were likely the first casualties of the winter kill. There could be a monster HSB lurking but seems unlikely. . In addition HSB are more active (higher metabolism) at cooler temps so they also use up more O2 being active in winter. That plus low O2 during possible winter kill will often get the more active fish first. Also (likely not an issue here) HSB can metabolize carbohydrates from fish food that BG and LMB can't so they can become morbidly obese on fish food carbs. This makes them more apt to have O2 problems.
