I understand that many of the shrimp that we collect originally came from the rivers of China. Further, I read that some of China's rivers are polluted. Is there a connection? Are the shrimp in danger anywhere?

Those shrimps like bee, tiger are 'mountain' shrimps, they are high up in the mountain streams, which are not affected by poluted rivers.

However, even those species are at risk from montane logging and the like. Within China - as across much of the world - many freshwater shrimp of all varieties are threatened (some gravely so) by agriculture (large-scape shifts in landscape composition, pesticide and fertilizer use, silt runoff, etc.), industrial byproduct contamination, direct and indirect sewage injection, introduction of non-native species, damming, mining, etc. Estuary and maritime pollution - especially mangrove destruction - impacts those species requiring high salinity for larval development.

China is a huge country. There should be polluted and non-polluted rivers. Not all are polluted. :D
