Lionfish – Why and How
Understanding why we need to bring down the number of lionfish and how they effect our surroundings in a negative way will help us all understand the right steps to take to fix the lionfish problem on Bonaire.
There is a lot of research available online and through other media that can help you understand the effect of the lionfish phenomenon.
How to Identify if it’s a Male or Female Lionfish
Lionfish have a spectacular appearance with distinctive fins and striped patterns that make them an ideal candidate for home aquariums. They are also known as scorpionfish, dragonfish, tigerfish and butterfly cod. There are about 22 species of lionfish in two genera. All are tropical fish with venomous spines.
Lionfish species reach different sizes ranging from 2 to 18 inches. Different species have different markings, different length fins and a different number of fin spines. They all tend to be solitary animals who come together to mate and form small groups with one male and two to seven females. Males are highly territorial and some species are more aggressive than others, with males more likely to kill each other rather than chase the other away.
The easiest time to tell male lionfish from female ones is when they are ready to mate. The males turn darker and the stripes are less visible, while the female’s patterns lighten. Mating usually occurs just after sunset. The belly, mouth and throat of the female turn silvery white so she is easier to see. The male circles the female and they ascend to the top of the water where she trembles her fins and releases her spawn, which he fertilizes.

Why are lionfish considered such a problem? Are lionfish really all that bad?
Yes. Non-native lionfish are a terrible problem in the Western Atlantic Ocean, Caribbean Sea and in the Gulf of Mexico. They are not a problem in their native ranges of the Indian Ocean, Southern and Western Pacific Ocean, and in the Red Sea. The world is still waiting to see how bad the problem with non-native lionfish in the Mediterranean is going to get since it is a relatively “new” invasion.
Invasive lionfish are out-breeding, out-competing and out-living native fish stocks and other marine species. The consequences impact food security and economies affecting over a hundred million people.
