Non-native species have accounted for approximately one-third of global annual aquaculture production, with this proportion exceeding 35% nowadays. While offering economic opportunities and sustaining livelihoods, non-native production also pose significant environmental risks.

According to the proportion of species donated and received, Asia and North America were the primary donors of non-native species, while Europe and South America receive a large number of species. Asian species have been extensively translocated both inter- and intra-continentally for aquaculture

This total production is largely driven by a handful of commonly farmed species (see Table 2 in the paper), many of which are farmed outside their native ranges and are recognised as high-risk invaders once established in non-native areas with monetary costs

Over the past decades, production volumes have risen rapidly, with native production being several orders of magnitude higher than its non-native counterpart, but the annual growth rate for non-native species' production (and economic value) is currently surpassed that of native one.

While the production of native fish and molluscs remains higher than that of non-native ones, algae—and especially crustaceans—are predominantly produced outside their native ranges. The latter with a rate of change exceeding 11,000% since 2000 compared to the previous two decades

The majority of production quantity has come from farming species within their native range (67.0% of the total global production; 1160.1 million tonnes), but 33.0% (571.6 million tonnes) has stemmed from the species farmed outside their native range, amounting to USD 1.17 trillion

We used FAO data, species' distributions, and the InvaCost database to quantify the global production and value of non-native farmed species (also native production) and their available monetary costs from 1950 to 2022 🌍🐟🦞
