I was concerned due to the extremly cold weather in the south this year that I would loose my threadfin. Water temps hit 42 for a few days but I never saw any threadfin floating, I did find about 20 around the ponds edge during this time and that was it thus I assumed that they made it.I assume if the died they would have floated up. Now the water temps are mid to upper 60s and all looks good but I dont see any signs of threadfin. I cant even catch any in a cast net. If the cold weater got them would they have floated or sank? What temp do threadfin spawn, I thought it was about 65. Thanks Jake
