Help - sharks

[ryane7]

so we launched at fwc then started fishing in 40' of water near a rig nothing but sharks so we continued hitting rigs we were eventually in 70' of water and still never caught any thing except sharks
what am i doing wrong we were bottom fishing carolina rigs with cigar minnows squid and pogies

the only fish i caught was king mackrel on the way in i was trying to find dolphin near the grass when this happened

any advice on avoiding sharks of finding dolphin would be helpfull
