Through the analysis of acoustic recordings of captive Pterois spp., this study has confirmed anecdotal evidence that Pterois spp. are soniferous. This report of sound production in Pterois spp. provides the foundation for future research into their specific acoustic capabilities including sound production mechanisms, the role of social behaviour a...

Species invasions in marine ecosystems pose a threat to native fish communities and can disrupt the food webs that support valuable commercial and recreational fisheries. In the Gulf of Mexico, densities of invasive Indo-Pacific Lionfish, Pterois volitans and P. miles, are among the highest in their invaded range. In a workshop setting held over a...

Numerous location-based diet studies have been published describing different aspects of invasive lionfish (Pterois volitans and Pterois miles) feeding ecology, but there has been no synthesis of their diet composition and feeding patterns across regional gradients. 8125 lionfish stomachs collected from 10 locations were analyzed to provide a gener...

The harmful algal bloom species, Karenia brevis, forms annual, often intense blooms in the Gulf of Mexico, particularly along the west Florida shelf. Though the ability of K. brevis blooms to cause mass mortalities in juvenile fish are well documented, the direct effect of bloom concentrations on larval fish has not been studied extensively. To bet...

This paper describes a non-traditional fisheries management concept and an indicator-based framework to encourage and guide management of invasive lionfish (Pterois spp.) fisheries in the temperate and tropical western Atlantic. We introduce the concept of optimum lionfish yield (OLY)—an extension of the concept of ecologically sustainable yield—wh...

Invasive lionfish (Pterois sp.) have the potential to affect reef communities in the western Atlantic through predation on native species. Lionfish are opportunistic generalist carnivores whose diet varies significantly among locations due to differences in local prey assemblages. As such, site-specific diet studies are needed to better inform loca...

Lionfish, native to reef ecosystems of the tropical and sub-tropical Indo-Pacific, were introduced to Florida waters in the 1980s, and have spread rapidly throughout the northwestern Atlantic, Caribbean Sea and the Gulf of Mexico. These invasive, carnivorous fish significantly reduce other fish and benthic invertebrate biomass, fish recruitment, an...

The goal of this study was to characterize lionfish diet and make inference about their potential ecological impacts in the Cozumel Marine Park (CMP), Cozumel, Mexico.

Invasive lionfish (Pterois volitans/miles) have spread across much of the tropical and sub-tropical Western Atlantic, and their range continues to expand along the east coast of South America. Their diet is composed primarily of teleost fish, followed by shrimp and then other crustaceans. At local scales, lionfish have been shown to reduce benthic...

The majority of invasive lionfish (Pterois volitans/miles) control has been through traditional diver-based removals. This strategy has been successful at reducing densities and, therefore, minimizing impacts at local scales (specific reefs). However, due to diving constraints, such as costs, limited bottom-time, and operable depths, this approach...

Invasive lionfish have proliferated throughout the Caribbean, causing extensive environmental damage to reef ecosystems. Given the high densities and extensive range, reef managers are developing local lionfish fisheries as a control strategy. Lionfish have a mild flavor, firm white meat, freeze well, and command high market prices, all factors tha...

Identification: Bothriocephalus acheilognathi is a cestode which parasitizes freshwater fish, particularly cyprinids (Marcogliese, 2008). It can be identified by a fleshy, arrow­head or heart shaped scolex (head region) with a relatively undeveloped terminal disc, and two anterolaterally directed bothria (slit­like openings) which are short and dee...
