An ornamental freshwater shrimp, Neocaridina davidi, is popular as an aquarium hobby and, therefore, a potentially invasive species. There is a growing need for proper management of this species to determine not only their optimum breeding conditions, but also their ability to colonise novel environments. We tested habitat preferences of colour morphs (brown, red, white) of N. davidi for substratum colour (black, white, grey shades, red) and fine or coarse chess-board patterns to recognise their suitable captivity conditions and predict their distribution after potential release into nature. We conducted laboratory choice experiments (n = 8) with three individuals of the same morph exposed for two hours to a range of backgrounds. Shrimp preferred dark backgrounds over light ones irrespective of their own colouration and its match with the background colour. Moreover, the brown and red morphs, in contrast to the white morph, preferred the coarse background pattern over the finer pattern. This suggests that the presence of dark, uniform substrata (e.g., rocks, macrophytes) will favour N. davidi. Nevertheless, the polymorphism of the species has little effect on its total niche breadth, and thus its invasive potential.

Marine ornamental fish production is still in its infancy compared with its freshwater ornamental counterpart. With ~1,800 wild caught fish species imported into the US each year, there is clear need for the expansion of marine ornamental production to include new species and families of fish. Distinct behavior and a wide range of colors makes blennies a popular choice in the aquarium hobby. These hardy fish are small and rarely aggressive to other reef species making them great for beginning aquarists, or fishes that can be added to an established reef community. The Blenniidae family is particularly common in the reef keeping community not only for their active nature, but also for their substrate cleaning and algae eating abilities.  According to a 2012 report on marine ornamental fish, the family Blenniidae is 11th most imported group into the United States by volume with over 75 distinct species being traded (Rhyne et al. 2012).  Due to this popularity many species of blennies are currently cultured and sold worldwide, with additional research underway to bring new species to market. A summary document highlighting culture protocols for members of the Blenniidae family is lacking and would provide valuable information to potential producers as well as the general public. This publication briefly covers: description and taxonomy, natural history, culture techniques, as well as diseases and marketing ornamental Blennids.

ABSTRACT Short-tailed pipe fish (Microphis brachyurus) is a freshwater organism with high economic potential for the aquarium hobby, so it is necessary to implement methods to promote its culture through studies of digestive physiology. General activities of acid and alkaline proteases were evaluated, as well as the effect of pH, temperature and inhibitors. The optimal pH of stomach proteases was 2, while the optimal pH of intestinal proteases was 10. Optimal temperature for the acidic proteases was 35 ºC, while for alkaline proteases it was 45 ºC. Thermal stability showed high resistance at 35 ºC for both acid and alkaline proteases (above 100% residual activity). Acid proteases are resistant at pH 2 (50% of residual activity), meanwhile alkaline proteases were highly resistant at pH 10 (90% of residual activity). Acid proteases were inhibited by 80% with pepstatin A and alkaline proteases were inhibited with TLCK and TPCK for trypsin (75%) and chymotrypsin (80%), respectively. Finally, metallo-proteases were 75% partially inhibited some serine proteases by 75% with EDTA. In conclusion, M. brachyurus has a good digestive capacity, since they can degrade a wide variety of proteins due to their greater proteolytic activity.

The trade of marine ornamental animals for home and public aquariums has grown into a major global industry. Since the 1990s, the aquarium hobby has shifted focus from fish to miniature reef ecosystems. Millions of marine fish and invertebrates are removed from coral reefs and associated habitats each year, and the majority are imported into the United States, with the remainder imported by Europe, Japan, and a handful of other countries. This shift in aquarium complexity demands increases in not only the volume but also the diversity of species harvested by collectors, who now must supply the trade with species sought for both aesthetics as well as ecosystem services (e.g., species that benefit the life support services of aquariums). Despite the recent growth and diversification of the aquarium trade, to date, data collection is not mandatory, and hence comprehensive information on species volume or diversity is wanting. The lack of this information makes it impossible to study trade pathways. Without species-specific volume and diversity data, it is unclear how importing and exporting governments can oversee this industry effectively. It is also unclear how sustainability should be encouraged given the paucity of data. To expand our knowledge and understanding of this trade, and to be able to effectively communicate this new understanding, we introduce the Marine Aquarium Biodiversity and Trade Flow online database (https://www.aquariumtradedata.org/). This tool was created as a means to assess the volume and diversity of marine fishes and/or invertebrates imported into the US over four years (2005, 2008, 2009, and 2011) and one month of additional data in 2000. It is available online for perusal by the public which will help communicate this new understanding in the trade of aquatic wildlife. To create this online tool, invoices pertaining to shipments of live marine fish and invertebrates were scanned and analyzed for species name, quantity, country of origin, and city of import destination. The results for October 2000 as well as the year between June 2004 and May 2005 have been published (Rhyne et al. 2012, http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0035808; Balboa 2003). Here we focus on the later three years of data and also produce an estimate of fish to create complete calendar years for 2000, 2004, and 2005. The three-year aggregate totals indicate that just under 2,300 fish and 725 invertebrate species were imported into the US, even though each year, just shy of 1,800 fish and 550 invertebrate species were traded. Overall, the total number of live marine animals decreased between 2008 and 2011. In 2008, 2009, and 2011, the total number of individual fish (8.2, 7.3, and 6.9 million) and invertebrates (4.2, 3.7, and 3.6 million) assessed by analyzing the invoice data are roughly 60% of the total volumes recorded through the LEMIS dataset.
