Fishing for Compliments

It has been reported that only 2/3rds of fish taken commercially by fishing fleets is eaten by people (https://www.theguardian.com/environment/2018/jul/09/one-in-three-fish-caught-never-makes-it-to-the-plate-un-report). The rest (in spite of many fish species being over-fished) is dumped at sea or rots before sale. The UN report suggests that there is an increasing reliance on farmed fish but this may not be a complete answer to the problem of over-fishing as they may generate disease in nearby fish stocks and are often fed with organisms removed from the seas (e.g. smaller fish and crustaceans) that wild fish (and other animals e.g. puffins) may need.
