Ocean fish numbers on ‘brink of collapse,’ WWF reports

The amount of fish in the oceans has halved since 1970, in a plunge to the “brink of collapse” caused by over-fishing and other threats, the WWF conservation group said on Wednesday.

Populations of some commercial fish stocks, such as a group including tuna, mackerel and bonito, had fallen by almost 75 per cent, according to a study by the WWF and the Zoological Society of London (ZSL).

Kate Humble: Aquaponics is the answer to our growing food crisis

Kate Humble: Aquaponics is the answer to our growing food crisis

A collective “ooh” went up as the condensation cleared from a new 12 x 7 metre structure to reveal the UK’s first aquaponic solar greenhouse, in the perhaps unlikely environs of Kate Humble’s 117-acre ex-council farm in Monmouthshire, Wales.

Inside, you can make out the blue of the fish tanks containing male tilapia (a species chosen as they grow rapidly to harvest size and as one of yesterday’s visitors put it “taste lovely on a barbecue”) and the raised beds full of fledgling vegetable crops. Of course, there is also much that you can’t see – which is rather the point with a closed-loop food production system that needs little interference; the vegetable beds fill and drain, twice an hour, sustained by nutrient-rich water from the fish tanks.

According to the latest edition of FAO’s The State of World Fisheries and Aquaculture, global fisheries and aquaculture production totalled 158 million tonnes in 2012 – around 10 million tonnes more than 2010.
