there are still a couple guides that are using alewives. the bait gathering process right now is hardcore and very labor intensive with many consecutive throws bringing up zero bait. also the water used to fill the tank is being pumped from 60 feet deep in the lake to have cold lake water instead of room temp city water that only adds to the stress levels. yes you can use ice to chill the water but you have to know what the water temps are down at the depths the shad are staying right now to match that temp, so just look at the graph , note the depth of the bait schools and lower the pump to that depth.
a serious bait tank set up is going to get you through for a couple/few hrs at best in the morning. you will need to keep at least 75+ alewives for a 2-3 hr trip, heres the math;
8 rods= 8 pcs of bait
total bait changeout every 20 minutes= 24 pcs of bait per hr
3hrs fishing time X 24shad/hr= 72
this doesnt count short fish, catfish, gar bites and short hits
unless...you hit a big school and get done in 10 minutes
i will use shiners if i have to, and as soon as my boat is back up and on the water....i will use shiners or suckers, a lot less work
