One Lincolnshire business has started the UK's first warm water king prawn farm - helping to supply the British market with an ethical and environmentally approved alternative to imported products from overseas.

Those who regularly dig into food production issues will be aware of the concerns around human trafficking, pollution and habitat destruction which has become associated with conventional prawn farms.

However, the Marine Conservation society has approved this UK farm's methods of production. The farm uses renewable energy to heat its closed loop aquaculture system, even filtering out waste from the water to use as fertiliser. In addition, the prawns are fed on fish-meal which is made from off-cut products from the human food chain, rather than contributing to depletion of fish stock or illegal fishing.

As consumers continue to seek more sustainable and ethical alternatives to conventional food production, could farming practices such as this be the answer?
