Cast nets are not allowed.
And yes, for larger fish like tuna or amberjack you need a boat.
But you can get bonito or snapper from shore.
Bonito can be cought on spinning or shore jigging tackle, you can use rods up to 60g, no need for stronger if you ask me.
And snapper... Well you can cast live or dead bait from shore, or go with shore jigging gear.
Here people often cast dead bait, mostly Adriatic squid (not imported).
Squid you can buy at local fish market or source from local fisherman. Just avoid frozen one from supermarkets.
I personally preffer shore jigging just because I love this technique.
Whatever you do, have one thing in mind. This is not ocean and we have a lot less fish, especially big predators.
Also, people are veeeery secretive about their fishing spots, so don't be shocked if you ask someone "is there any fish here?" and they try to tell you "NO"
If you get ultralight or light spinning setup for lures/jigs with rod rating up to maybe 20 or 25g you can have a lot more action from ports and docks catching mackerel in the morning and at sunset. Maybe even some seabass.
What we have in abundance close to your area are bluefish. Rod up to 40-45g is more than enough for our bluefish.
I think dorados will come here later in the year, maybe october. Not sure.
If you want more action, go light for mackerel type of fish

If you are happy if you catch nothing, choose whatever you want 😅
And sorry for jumping around, I was just brainstorming
