Snook at Sebastian Inlet — Sebastian, Florida

Snook and Sebastian Inlet are closely linked. The Sebastian Inlet District calls the snook (Centropomus undecimalis) and the redfish two of the most renowned game fish of Sebastian Inlet, and describes snook as arguably the rock stars of game fish at the inlet. The man-made channel at the Brevard and Indian River county line connects the Indian River Lagoon with the Atlantic Ocean, and snook use both sides of it at different stages of life.

One record ties the species to the town by name. The Florida Fish and Wildlife Conservation Commission species profile lists the Florida state record snook at 45 lbs 12 oz, caught near Sebastian. The same profile describes a fish that grows up to 48 inches and 50 pounds, larger than other snook species, with a protruding lower jaw, a sloping forehead and a black lateral line that extends onto the tail.

The Sebastian Inlet District groups snook with redfish, black drum, menhaden and striped mullet as fish that regularly migrate between Sebastian Inlet and the Indian River Lagoon and spawn in both the Atlantic Ocean and the lagoon's shallow estuarine waters. According to the District's 2023 fish series, snook spawn near reefs, wrecks and the jetties at Sebastian Inlet. Their eggs are the size of pinheads, hatch in less than 20 hours, and the larvae settle in the shallow waters of the Indian River Lagoon.

The young fish stay close to shore. The District reports that juvenile snook hide out in mangroves and in the nearby Sebastian River, start eating other fish at about one-half inch, and begin leaving the mangroves for the open lagoon by about six inches. In one three-hour sampling set at Jack Island Preserve State Park, researchers caught 1,500 one-inch juvenile snook. The District describes the shoal side of Sebastian Inlet, with shallow water, mangrove prop roots and seagrass beds, as ideal habitat for juvenile snook.

Biology adds two more details that matter at Sebastian. The FWC states that snook begin life as males and that between 18 and 22 inches some become females, that they form schools during spawning season, and that they cannot tolerate water temperatures below 60 F. Temperature is also one of the metrics the FWC now uses to evaluate the snook fishery in the Indian River Lagoon Region.

Sebastian Inlet falls inside the FWC's Indian River Lagoon Region. According to the FWC snook regulations page, the region's northern coastal boundary is Lytle Avenue/South Causeway in New Smyrna Beach and it extends south to the Martin and Palm Beach county line, including all waters of the Kissimmee River and Lake Okeechobee. As of October 2026, the FWC lists these rules for the Indian River Lagoon Region:

Closed season: December 15 to January 31, and June 1 to August 31. Slot limit: not less than 28 inches or more than 32 inches total length. Bag limit: one fish per person per day. These Indian River Lagoon Region rules are the ones that apply on the jetties, in the inlet channel and on the lagoon flats around Sebastian.

Other statewide conditions also apply to snook caught near Sebastian. The FWC states that no commercial harvest or sale of snook is permitted, that a snook must remain in whole condition until landed ashore, that captain and crew on a for-hire trip may not retain a bag limit, and that the only allowable gear is hook and line. Anglers need a snook permit and a recreational fishing license. The FWC notes that snook permit sales are final and that permit fees are not refunded even when the species is closed to harvest.

The current regional system started with public meetings, one of them in Sebastian. Sebastian Daily reported that the FWC held a snook workshop on March 23, 2023, at Sebastian City Hall, reviewing habitat, fishing effort and stakeholder feedback to evaluate the fishery at a more local scale. At that time FWC staff proposed ten new management regions with rules based on the status of the fishery in each.

At its October 2023 meeting, the FWC approved nine snook management regions, with the new rules taking effect January 1, 2024. For the Southeast, Indian River Lagoon and Northeast regions, the open seasons are February to May and September to December 14, with a bag limit of one fish and a slot of 28 to 32 inches. In other words, the closed seasons that anglers at Sebastian Inlet already knew were kept for the Indian River Lagoon Region, while Gulf coast regions received different seasons and a 28 to 33 inch slot.

The FWC describes the 2023 approach as using multiple metrics, including spawning potential ratio, relative abundance, habitat, harmful algal blooms, fishing effort, temperature and stakeholder feedback, to evaluate the fishery region by region. It publishes an annual review for each region, including a 2025 Indian River Lagoon Snook Annual Review. According to the FWC, snook regulations in the Indian River Lagoon Region could be changed each year in response to those reviews.

The snook fishery at Sebastian depends on an inlet built by people. The Sebastian Inlet District records that settlers first tried to cut an inlet at the site in the 1880s, that the District was formed on May 23, 1919 to maintain the channel, and that in 1948 the inlet was blasted open with surplus U.S. Navy demolitions and has remained open ever since. From 1968 into 1970, the North Jetty was overhauled and extended 500 feet and the South Jetty was extended and capped, creating the structures where snook spawn today.

Harvest rules came later. The FWC states that snook harvest has been regulated since the mid-1950s and that in 1985 snook were considered severely depleted. Over the following decades, Florida prohibited commercial harvest or sale, required a snook stamp, and refined seasons and slot limits. According to the FWC, snook stocks have since rebounded and exceed its management goal of a 40 percent spawning potential ratio on both coasts, a statewide result that includes the Indian River Lagoon fish passing Sebastian Inlet.

Research money comes partly from anglers. The FWC reports that the snook permit fee funds tagging work and monthly fisheries-independent sampling in four estuaries where common snook are abundant: Tampa Bay, Charlotte Harbor, and the southern and northern portions of the Indian River Lagoon. The Sebastian Inlet District has also monitored seagrass in the inlet flood shoals since a 2007 channel realignment, continuing beyond the five years its permit required.

Snook range well beyond the jetties. At Pelican Island National Wildlife Refuge, in the lagoon off Sebastian, the U.S. Fish and Wildlife Service permits fishing in the open water areas of the refuge and lists redfish, snook, sea trout, flounder, mangrove snapper and jack crevalle among the sportfish there. On the refuge's trail system, Bird's Impoundment Trail allows bank fishing on the lagoon side, and the Service names blue crab, red drum, snook and tarpon among the most popular catches. State snook rules for the Indian River Lagoon Region apply in these refuge waters as well.
