When using anchovies, I insert the hook thru both gill plates on the head. That is strongest area to keep the anchovies on the hook. The anchovies must be frozen to stay on the hook. The alternative is to use a piece of striper filet with the skin attached as bait instead of using an anchovie. That will stay on the hook better and be equally effective. The hook to use is a
2/0 Mustad wide gapped hook. Very few bites are missed using this hook even for people new to fishing. You can buy 100 at a time for about $12.00. Attaching the 2/0 wide gapped hook to a swivel will help prevent line twist.
The clarity of the water on Lake Powell requires using the most invisible fishing line known to mankind. If the fish can see your line, your are screwed no matter what is on the end of it. This time of year it is possible to see the lake bottom at 40 feet deep. Need to use a small diameter clear florocarbon fishing line. Do not use monofilament. I use 8 pound test clear florocarbon line for all species.
If the stripers are shallow (30 feet), I do not put any sinkers on the line and let the bait fall slowly. If they are deep (50+ feet), I'll add an 1/8 ounce split shot to the line so it sinks faster to the bottom.
Hope this helps. Good Luck!
