Fishtive

“All the fish in a lake in Bristol are to be removed and destroyed in a bid to discourage fishing.” (http://www.bbc.co.uk/news/uk-england-bristol-35134740)

The removal of the fish will be carried out by specially trained fishers over the next ten years.

Fly-fishing

“If the invasive goldfish escape into waterways downstream, they pose a threat to native species such as channel catfish, pumpkinseed and blue gill sun fish. … Authorities are seeking the public’s help in finding out who dumped the goldfish.” (http://uk.reuters.com/article/2015/04/11/us-usa-colorado-goldfish-idUKKBN0N12BA20150411)

The pumpkinseed originally drew the canaryfish. The catfish had to be sent in after it, but became distracted by the magpiefish that were following the blue gill sun fish. Thankfully this bungled trophic cascade was halted before helpful local residents released dogfish, lionfish or human angler fish.
Next week: more non-native nonsense here on Channel Catfish.

Plastish

“Filter feeders and sediment feeders and organisms that feed on the surface layer of the lake, all swallow these plastic particles mistaking them for food. … [then] when fish are feeding on these organisms they accumulate these particles also in their tissue.” (http://www.bbc.co.uk/news/science-environment-24434378)

Human populations using fresh water for drinking and agriculture are concerned, but supermarkets are delighted that fish are self-wrapping.
