High densities of exotic fish are negatively correlated with native species richness. Dams tend to affect upstream species richness, that is, the number of fish species in the ecological community. Rarity may be defined by very narrow (albeit totally absolute) criteria; for example, while most koi retail for $10 to $20, exceptionally well-bred individuals often sell for tens of thousands of dollars at auction.
