Feeding lionfish to sharks

  • A divemaster off the coast of St. Kitts spears lionfish (an invasive species in the Caribbean) and feeds them to sharks to teach them to seek out the fish as prey. The lionfish invasion is considered to be one of the most serious recent threats to Caribbean and Florida coral reef ecosystems. Culling by marine protection agencies and volunteer divers is an important element of control efforts. Adult lionfish have few identified natural predators, likely from the effectiveness of their venomous spines. Moray eels, bluespotted cornetfish, and large groupers have been observed preying on lionfish. During our diving at St. Kitts, we witnessed that sharks are also capable of preying on lionfish with no ill effects from their spines. Development of market-based approaches, which create commercial incentives for removals, has also been seen as a means to sustain control efforts. The foremost of these market approaches is the promotion of lionfish as a food item. When properly filleted, the naturally venomous fish is safe to eat. Another control method is the use of lionfish spines, fins and tails for jewelry and other decorative items. Lionfish jewelry production initiatives are underway in Belize, the Bahamas and St. Vincent and the Grenadines.

      @@FirstFamilyCharger No. Sharks aren't competitive. They are apex predators feeding. In my hundreds of dives with sharks, they have never behaved this way. Humans are not on the menu, and in fact the bubbles divers create are an annoyance. Sharks try their best to avoid people and also these very types of situations, but simply can't help themselves with injured prey on a harpoon.
      However, divers behaving this way is quite irresponsible, for reasons I posted directly to the video. I can post it here as well if you wish :)

      By the way, no diver should ever do this, for a variety of reasons, including but not limited to:
      1) It is dangerous for the shark. The extremely sharp harpoon poses a significant risk to an aggressively twisting shark.
      2) It is dangerous for all divers that frequent the general area. The fact that you are training the sharks to associate humans with feeding inevitably leads to sharks approaching future divers with feeding expectancy and aggression. This has been proven in all oceanic environments where chumming is common, from Jupiter, Florida to Isla de Cocos in Costa Rica to Bali in Indonesia.
      3) While I recognize the ecological impact of lion fish, sharks play a far bigger and more important role in ecological control. By training them to wait for their food, they stop performing their natural roles of population control on the reef.
      I understand how humans got ourselves into this mess with lion fish in the Caribbean, and how we feel we can fix our way out of it. However, throughout history we have made environmental disasters worse when trying to introduce extra variables or controls.
      It is generally accepted biological principle to leave natural habitats as they already are. In the case of the Caribbean, that is no longer possible. However, training the apex predator of the area to alter behavior is a disasterous idea. Human control of the population is the best regarded method until we can determine a way to prevent lion fish from spawning (introducing a genetic variant of lion fish that cannot spawn into only the affected areas, for example) or by luring only lion fish into traps.
      But please, for the sake of all stakeholders involved, including humans, sharks, and the general environment, please refrain from doing this.

    Very smart. Just looked it up, and sharks, groupers, and eels are natural predators of lionfish in their native habitats. Lot more efficient than having human divers hand pick them one by one ad infinitum in perpetuity.

    You're actually teaching them to take fish off of the spear of someone spearfishing. If another spearfisherman is spearing some other type of fish and then all of a sudden these sharks show up, they don't know that the sharks are used to it, they may actually think the sharks are being aggressive towards them.

      they compete with native predators, leaving them without food; they reproduce faster and due to their young not having as many predators, a much higher percentage reaches adulthood; once they are adults, lionfish are eaten by far less things (only large morays, groupers and sharks will take them); they eat a lot of native fish and crustaceans, applying pressure to their populations

      A lot of reef sharks interact with divers, the only issue is if they see someone spearfishing in the future theyll likely expect to be feed by them. If the divers are aware of this it shouldnt be an issue they might just have to give there catch to the sharks though haha
