>> Could these scenes from a mad scientist's laboratory represent environmentally friendly solutions to the very unenvironmentally friendly industry of fish farming? Maybe. This is Norway, one of the world's power houses of sea food production including from fish farms like this one, full of hungry fish. But the realities of climate change and environmental damage caused by aquaculture itself means the industry is starting to see the writing on the wall.
Find sustainable solutions, or there simply won't be an industry anymore. And this country is ahead of most peers. Enter this place, a startup called CO2BIO. It's developed a method whereby carbon dioxide from this refinery is captured and used to feed algae in these tubes. The algae is then used to feed the fish for farming, as opposed to say fish meal which is basically ground up dead fish.
Fish that's sourced from an already much depleted ocean.>> Here we are having a look into growing microalgae on waste streams, for example, or the left-over products from aquaculture as the poo of the fish, or the fish blood. And as well for municipality waste, organic liquids. Yeah, that's making it a lot sustainable if we manage actually to replace the pure chemicals that we need with those waste streams as nutrients.
>> Another possible answer, insects. It might seem obvious to anyone who's used it as bait on a fishing pole before. But according to the Institute of Marine Research in Bergen, one key upside to meal worms or fly larvae is that like the algae we just saw, they feed on human waste products.
The aquafly project, as it's called, says it's looking into how it can be scaled up.>> The insect production is a much more environmentally friendly production. So you use less water, less CO2 emissions, much less land needed to produce it. And they also use to feed that they eat very efficiently, so it's a a very efficient industry.
