Biscayne in July: what the park service says

July brings lobster mini-season: two days over the last consecutive Wednesday and Thursday of the month, from 12:00 a.m. Wednesday until 11:59 p.m. Thursday. In Biscayne the bay side stays shut, because the sanctuary there bans taking lobster at any time of year, so the hunting happens east of the islands. Every person in the water must carry a measuring device. Lobsters may be caught only by hand or with hand-held nets or bully nets; spears, hooks and grabs are not allowed. Florida law also requires a 20 by 24 inch diver-down flag flown from the boat's highest point, and divers in open water must stay within 300 feet of it.
