Wouldn’t it be strange if China, the smog capital of the world, started assuming leadership on environmental causes like global warming, clean air, and … sustainable fish farming.
The PRI radio show Living on Earth recently explained how China was tackling the latter challenge.
“Consumer demand in both the U.S. and China for safe and healthy farmed fish is shaping aquaculture practices in the world’s most populous country. And fish farmers are using traditional Chinese medicine as well as high-tech monitoring systems as they strive to keep their fish healthy and their farming practices transparent. Jocelyn Ford reports from the Hainan Province. …
“HAN HAN: With such a huge population in China, if we didn’t have aquaculture, if we totally relied on the wild fishery. I guess we would already running out of all these wild fish, maybe 10 or 20 years ago.
“FORD: That’s Han Han, the founder of the China Blue Sustainability Institute, China’s first non-governmental, environmental organization focused on sustainable fishing and aquaculture. Today, aquaculture accounts for one of every two fish that land on the dinner table worldwide, and it’s growing faster than other sources of animal protein. China is the global aquaculture leader, and because of its expertise here, it wants to help other countries. …
“Aquaculture is expanding globally at about five percent a year, and that’s a plus for some of the Earth’s most pressing environmental issues. For example, compared to a pound of beef, a pound of fish has only about one-seventh of the carbon footprint. But large-scale aquaculture has created new problems. Naturally, farmed fish need to eat. And gone are the days when Chinese fish farms were all organic. Qi Genliu is a professor at Shanghai Ocean University.
“QI: Traditionally we used grass to culture grass carp.
“FORD: That changed with the growth of the fish feed industry and the need to feed carnivorous marine fish [and keep them disease free with antibiotics]. …
“The founder and president of The Fishin’ Company, Manish Kumar, started coming to Hainan to build a coalition for a safer, more environmentally sound and sustainable tilapia industry [using traditional herbal medicine instead of antibiotics]. His company is sponsoring trainings, and offering financial incentives to a few model farms that invest in improvements. The idea is, others will follow suit if they see it makes financial sense. …
“FORD: His ideas include increasing omega-3 levels in the tilapia, the fish oil that may help lower risk of heart disease, cancer and arthritis. To help reassure customers who are nervous about what their fish are eating, next year he’s planning a state of the art oversight system that involves cameras, QR codes, and consumer monitoring.
“KUMAR: We will now proceed to do something no one in the industry has done before. Put a camera system into the farm area. A customer buys a bag of fish. You have a QR code on the bag. Run your smartphone through our QR code on the bag, and you will have a chance to see the actual farm that raised this fish in your bag. And how it’s being raised.
“FORD: Customers can see the type of feed, and the plant where the feed was made, and the insomniacs can watch the fish grow 24/7. Manish Kumar says the extra cost will be negligible. As the largest supplier of tilapia, he expects to be able to take advantage of economies of scale.”
