gave OP a good response in PM...basically fish meal, clay, baiting license if going to use the fishmeal....cast net..recommend 4-6 footer at most if never thrown one before...at night and rising tide with lights shining on water.
if not baiting, rising tide...watch shore birds or predator fish chasing them....throw net, empty, try again. Takes some practice to get a full bloom on your net....and even then wind and stuff can mess it up but lots of fun done off floating dock or deck of boat with no rails or accessories to get caught in net. Otherwise standing knee deep in water is good way...
some videos on youtube that are helpful in learning to throw a net....otherwise drive around and look for locals and ask them to teach you to throw the net then buy them a beer....win win
born and raised here in charleston....so grew up running tidal creeks in canoe...shrimping off docks....fishing...hunting....enjoying outdoors.
