Lionfish (Pterois miles and Pterois volitans) are known for their invasive success in the western Atlantic and Caribbean. With few marine fish invasions of similar magnitude being documented, the introduction of lionfish in this area has been deemed one of the fastest and most ecologically harmful introductions to date. Furthermore, this invasion is thought to be caused by negligent aquarists who released ornamental lionfish off the coast of Florida in 1985. Interestingly, lionfish are rare in abundance throughout their native waters of the Indo-Pacific and factors controlling lionfish’s native populations are little studied and not clearly defined. Through the analysis of the Marine Aquarium Biodiversity and Trade Flow database for the years 2008, 2009, and 2011, it was determined that approximately 137,723 lionfish were exported to the United States with Los Angeles, CA being the most popular point of entry. Of this total, 45.5% originated from the Philippines, 27.7% from Indonesia, and 14.5% from Kenya. Pterois volitans was exported from 15 different countries and on average 19 times more than Pterois miles which was exported only from three countries. This paper questions: 1) if the ornamental aquarium trade is affecting lionfish’s native populations and 2) if the lionfish imports could be leading to more introductions in non-native waters. Ultimately, this paper acts as a short communication identifying a need for further research and attention towards this

ABSTRACTThe global aquarium trade can introduce alien freshwater invaders, potentially impacting local aquatic ecosystems and their biodiversity. The role of the aquarium trade in spreading freshwater red macroalgae that hitchhike on ornamental aquatic plants and animals is unassessed. We investigated this human-mediated phenomenon via a broad biodiversity survey and genetic analysis of freshwater red algae in the field and aquarium shops in East Asia. Using rbcL-based DNA barcoding, we surveyed 125 samples from 46 field sites and 88 samples from 53 aquarium shops (213 samples in total) mostly across Taiwan – a key hub in the global aquarium trade – as well as in Hong Kong, Okinawa (Japan), the Philippines, and Thailand. We augmented our rbcL sequences with GenBank rbcL sequences that represent 40 additional countries globally. We found 26 molecular operational taxonomic units (mOTUs) in Taiwan, some of which are cryptic. Phylogeographical analysis revealed three potential introduced mOTUs in Taiwan, which exhibit no local genetic variation in Taiwan and are distributed across continents. Also, we posit that some presumably endangered freshwater red algae may be preserved in aquaria, an unintentional ex situ conservation site for these organisms that are vulnerable to water pollution from anthropogenic disturbances. Collectively, these data suggest that freshwater red algae have been hitchhiking and dispersed via the aquarium trade, an important and overlooked mechanism of introduction of these organisms across the globe.
