To fish in Fort Lauderdale or any place in Florida, you are required to have a current fishing license. This is the law and fishing without one can lead to steep penalties.
If you want to fish in waters where both fresh and salt water fish live, you can purchase a combination license.
There are some exceptions to requiring fishing licenses in relation to freshwater fishing. These exceptions include residents of Florida who are 65 years or older and who possesses proof of age and residency or a Resident Senior Citizen Hunting and Fishing Certificate.
In addition, this certificate can also be used in the state of George, except for trout fishing, which requires and additional stamp on the license, residents of Florida who have proof of being totally and permanently disabled or who have a Florida Resident Disabled Person Hunting and Fishing Certification.
The proof for disability must come from any of the following: Florida Worker's Compensation, Railroad Retirement Board, Social Security Administration (SSI or SSDI also accepted), United States Armed Forces, United States Veterans Administration, children under the age of 16, Florida residents who possess a freshwater commercial fishing license, any person confirmed as a client by the Florida Department of Health of having developmental limitations, a Florida resident in the US Armed Forces not stationed in Florida but who is on leave for a minimum of 30 days (orders must be submitted), residents fishing from their own resident's county using natural or live bait, and poles or hand lines without reels as long as the fishing is for personal use, fishing from private ponds that sit on 20 acres or less, any person fishing from their own private residence, fishing at Lake Seminole or St. Mary's River with a valid George fishing license, and fishing during any special free fishing weekends offered in Fort Lauderdale.
In all other cases, if you want to enjoy freshwater fishing, you will need to purchase a fishing license, which can be found at any local sporting good store or a local discount chain.
Bottom line: Get your fishing license and enjoy some of the best fishing, either fresh fishing, saltwater, or both, in the entire southern United States!
