“…Now there are new populations in the areas where the species was never cultivated proving that this alien species can colonize new locations. This highlights the potentially invasive nature of the giant freshwater prawns [103]. And brings again an example in which the introduction of a species, voluntarily or not, in a region where it is not native and where its proliferation causes ecological damages threatening natural biodiversity [104].…”

“…Despite the export market success in 1989, commercialization was facing problems due to unreliable production fluctuation, and concurrent Asian production.

This is a review of the importance of inland water fisheries and fish farming as a food source in the Amazon basin. Small-scale fisheries resources have been depleted and climate change poses a growing threat, failure to address the issues confronting the sector places the food safety and livelihoods of millions of people at risk. The governments should form partnerships with the communities for them to assist in managing the resources. The fishers would gain in this co-management but also have to assume responsibility for their decisions and actions. Co-management is always far better than no-management. From the landings, trade, and consumption of fish, it has been estimated that the total fish catch in the Amazon basin is above half a million tonnes/year in live weight. However, this figure is very rough given that 75 per cent of represented landings come from Brazil with no updated official statistics after 2010 on commercial landings. Aquaculture offers the largest potential to increase fish supplies in the long term but the rapid growth is unevenly distributed among countries. Three major aquaculture producers are Ecuador, Brazil and Colombia but Amazon basin aquaculture has some importance also in Peru. Aquaculture development in the region is facing many challenges including to combat against diseases and epizootics, the need for better hatchery and grow-out technology, brood stock improvement, appropriate and most economic feed production and water-quality management. This paper pays also attention to the unwanted spread of alien fish species often as escapees from aquaculture. Annual per capita fish consumption in kg/capita in the Amazon basin countries varies between 2.6-25.3 kg/year, the three leading countries being Guyana, Peru and Suriname. The consumption is fairly low compared to the European Union and the global averages which are around 27 and 22 kg/capita/year, respectively. However, in all Amazonian countries, 50 up to almost 100 per cent of artisanal freshwater fishing takes place for personal consumption, implying that it may not be fully recorded in official consumption statistics. Ornamental fish culture and trade have had an important role in the Amazon basin countries, the three biggest producers and exporters of aquarium fish being Brazil, Colombia and Peru. In 2008 economic crisis hit Brazil and started the decline of the ornamental fish trade. One reason for the decrease in the trade was the competition with neighbouring Colombia and Peru with less bureaucratic systems and fewer restrictions on which species can be exported. International pressure to stop the commerce of wild-caught fish intensified and the increase of husbandry practices and reproduction in Southeast Asia caused the downturn of the Brazilian Amazonian market. Thousands of families lost their livelihoods and many fishermen were forced to start working in sport fishing and commercial fisheries.

Background This is the first record of the alien shrimp Mierspenaeopsis sculptilis in Brazil. The invasion was detected within Marine Extractive Reserves based on eight specimens accidentally caught by local fishermen using trawlnets focused on fisheries of native species. These specimens were transported to the Laboratory of Applied Genetics and morphologically identified as Mierspenaeopsis sculptilis (rainbow shrimp). The taxonomic status of analyzed samples was confirmed by DNA barcoding using a 627-bp fragment of the Cytochrome C Oxidase Subunit I (COI) gene. Results A single haplotype was recovered from the eight specimens, being identical to a haplotype reported in India, where this species naturally occurs, and in Mozambique, where the rainbow shrimp is considered an invasive species. The present analyses indicated a putative invasive route (i.e., India-Mozambique-Brazil) mediated by shipping trade. Conclusions This study presents the first record of Mierspenaeopsis sculptilis in Brazil, in areas of extractive reserves on the Amazon coast. Notably exotic species can cause imbalance in the ecosystem, harming native species. In view of this, the registration of new invasions is essential as they contribute to the implementation of control plans.
