Employing exotic animals and plants can help the fight against hunger and power economic development. UJAT’s Mike Mitchell reports.
Is there more that can be done with so-called ‘invasive’ species?
The introduction of ‘alien’ or ‘non-native’ species varies greatly around the world and through history. From stowaway rodents on cargo ships rodents, seeds or pollen clung to clothing or deliberately introduced as with Japanese knotweed, to pets released to unexpectedly thrive in the wild like lionfish, they are usually considered pests or weeds in their new homes.

A think-tank suggests that all fishing in Europe should cease to let stocks recover. Credible plan or silly talk? Stefano Mariani tests the bait.
Would a complete ban on all fishing in Europe for up to nine years be an effective way to replenish fishing grounds?
That’s the conclusion of the report ‘No Catch Investment’ from the UK-based think tank New Economics Foundation (NEF) that looked at 54 northeast Atlantic fish stocks, 49 of which are overfished. They say that halting current overexploitation would allow fish stocks the time to recover. And that the long-term increase in their monetary value as populations bounce back (£14.63Bn per year) will offset the short-terms costs (£10.4Bn) of not fishing (compensating fisherman etc.) which they suggest should be paid for by the private sector – the people who will make the estimated £4Bn profit later – not the public purse.

Harvesting plants from the sea is an essential part of successful marine agronomy, says John Forster.
Aquaculture has been the subject of two recent high profile reports. The first, entitled Blue Frontiers, begins by asserting ‘There is a pressing need to elevate the debate on the future of aquaculture and to place this in the context of other animal food production systems, including wild capture fisheries’. The second report made the front cover of Time Magazine and poses the question ‘Can farming save the last wild food?’
Both reports make important points. Between 1970 and 2008, global aquaculture production grew (PDF) at an average rate of 8.4% per year, and aquaculture remains one of the fastest growing food producing sectors measured in terms of year-on-year percentage gain. Furthermore, because the world’s fisheries are yielding all they can, there is simply no option but to farm seafood if growing human demand for animal protein is to be met.
