Fish for the Future

According to the UN DESA report, “World Population Prospects: The 2015 Revision”, the current world population of 7.3 billion is expected to reach 8.5 billion by 2030, 9.7 billion in 2050 and 11.2 billion in 2100.

Humans need seafood. The benefits of eating seafood are well documented, the most well known are Omega 3 EPA and DHA fatty acids.

On 7 July 2016, the FAO advised that global per capita fish consumption rose to above 20 kilograms a year for the first time.

Supply-chain and other improvements have also raised the share of world fish production utilised for direct human consumption to 87 percent or 146 million tonnes in 2016. Up from 85 percent or 136 million tonnes, in 2014.

Farming seafood is one of the most effective ways of producing dietary protein because marine animals do not have to expend energy on fighting gravity as is the case with land animals.

In my opinion, the way to make the necessary leap forward  in aquaculture production in order to meet the increasing demand is to develop integrated multi species ecosystems rather than continue to copy land based monoculture farming.

In this way consumers will be able to continue to obtain a variety of species.  If not, the choice in future may become limited.
