Venture capital firm BP Ventures, an arm of the British multinational oil and gas company BP, is investing $30 million (€26.3 million) in US-based alternative feed ingredients company Calysta to accelerate the company's development of natural gas fermentation plants that produce ingredients for fish feed.

"When you talk about moving the needle in terms of food security, you're talking substantial scale, but one of the biggest bottlenecks for aquaculture is access to feed, and we need alternative protein -- we can't keep ripping down the rain forest planting more soy," Calysta CEO Alan Shaw told IntraFish.
