Tough Fishing

[basstech]

Lately the fish seem deep and inactive. I was catching fifteen or so fish a Day with three or four keeps A month ago...but now am only catching 4 or 5 and one good keeper in the last three weeks. I see mostly stuff in deeper water yesterday sitting in 15 to 20 ft. watter at 15' to 25' depth of water. I didn't seen any thing out in 30ft' of watter...or from 15' shallower . The fish we caught were shallow. Anyone got any ideas where I could find a concentration of keepers? I threw a deep diving fat free shad and covered the water where I did see fish/ baitfish and other's. The sonar is too crappy to tell what species was down there other than the obvious bait balls. Didn't get a strike though. We didn't catch a thing or even get a bite untill we started fishing the shallower weed lines. Mostly on jig and trailer. I caught two small ones on a chrome/blue back bomber 7a. Nothing on anything else...but they were damn near swallowing the jig. Was a long time between bites too. Anybody got any ideas?
