About Lionfish Fishing in Grand Case
The invasive lionfish has become both an ecological concern and a unique fishing target throughout the Caribbean. These venomous but delicious fish are found on reefs and wrecks from 1 to 1,000 feet deep. Many Caribbean destinations now encourage lionfish harvesting through spearfishing and specialized traps. The white, flaky meat is considered a delicacy, and removing them helps protect native reef fish populations.
Lionfish (Pterois volitans and Pterois miles) are venomous invasive species from the Indo-Pacific that have colonized the entire Caribbean and Western Atlantic since the early 2000s. With no natural predators in Caribbean waters, lionfish populations have exploded, devastating native reef fish populations by consuming enormous quantities of juvenile fish and crustaceans. Lionfish are now the subject of aggressive removal efforts across the Caribbean, and many islands encourage anglers and divers to harvest as many as possible. Despite their venomous spines, lionfish have firm, white, delicately flavored flesh that is considered excellent eating — often compared to hogfish or grouper. Removing and eating lionfish is one of the few cases where harvesting a species is a conservation act.
Scientific name: Pterois volitans

How to Catch Lionfish in Grand Case
Techniques & Bait
Spearfishing while scuba diving or freediving is the primary harvest method — lionfish are slow-moving and relatively easy to approach on the reef. Purpose-built lionfish spears (pole spears with paralyzer tips or Hawaiian slings) are standard equipment. Containment devices (ZooKeeper or similar puncture-proof tubes) keep harvested lionfish and their venomous spines safely contained underwater. Lionfish are also caught with small hook-and-line rigs baited with shrimp or cut bait dropped directly in front of them on the reef. Some Caribbean islands host lionfish derbies — competitive removal events that can harvest thousands of fish in a single day. Specialized lionfish traps designed to attract them with structure are being developed and deployed in some areas.
Recommended Tackle
Spearfishing: pole spear (3-6 ft fiberglass or carbon fiber) with a paralyzer or trident tip, puncture-proof containment tube (ZooKeeper), puncture-resistant gloves, and dive gear. Hook-and-line: ultralight or light spinning rod, 1000-2500 reel, 6-10 lb line, small hooks (size 2-1/0) baited with cut shrimp. The key safety equipment is puncture-resistant gloves — lionfish spines deliver an extremely painful venom that causes intense pain, swelling, and potential allergic reactions. The venom is heat-labile and is neutralized by hot water immersion (110-115 degrees Fahrenheit) if stung.
Best Bottom Fishing Fishing Spots in Grand Case
Top spots where local captains target lionfish and other bottom fishing species.
Grand Case Bay
Grand Case Bay is a calm, horseshoe-shaped bay on the French side of Saint-Martin where tarpon, barracuda, and jacks cruise the sandy shallows and reef edges. The bay's clear water and protected orientation provide excellent sight-fishing conditions for wading anglers targeting fish along the grass beds.
Petite Plage Cove
Petite Plage is a small, secluded cove north of Grand Case where rocky shoreline meets sandy bottom, creating habitat for mangrove snapper, yellowtail snapper, and barracuda. The cove's sheltered waters and nearby reef provide diverse inshore fishing within walking distance of Grand Case village.
Anse Marcel Mangroves
The mangrove-lined shores of Anse Marcel bay east of Grand Case provide sheltered inshore habitat for tarpon, snook, and juvenile barracuda. The enclosed bay's calm waters and overhanging mangrove branches create ambush points where predators concentrate during tidal movements.
Grand Case Reef Edge
The shallow reef edge fronting Grand Case beach holds bar jacks, yellowtail snapper, and needlefish in 5-15 feet of clear water. Shore anglers cast to fish cruising the reef-to-sand transition, while the reef's deeper outer edge attracts barracuda and larger jacks.
