You don't need a fishing license in order to fish at the Naples Pier or the Ft. Myers Beach Pier. All you need is some sort of a fishing pole and some lures or even live baits. Therefor, you will see quite a few "fishermen" on the pier at all times. Some are tourists, some are locals, some are kids, some are adults, and of course some are birds.
The most prevalent fish in this area of the gulf are what they call catfish. They are not your average catfish that weigh 2-7 pounds (1-3 kg) and are found fried at local restaurants in Illinois. But rather they are the gafftopsail catfish. They have the same silvery-grey color and are often found in the same schools as the hardhead catfish but they are somewhat a nuisance. Their pectoral and dorsal fins are poisonous; a sting can cause horrible pain that lasts a long time. They are also difficult to handle as they tend to excrete a toxic slim coating from their skin when caught. But it is said that once they are cleaned thoroughly they are a good eat.
I have never eaten a gafftopsail catfish and after listening to the banter of some of the regular fishermen (especially when one of them decided to filet his catch) I don't think I am interested in tasting one. Nevertheless, I did enjoy listening to the bants, watching people and taking some candid shots of the environment.
