Air China bans shark fin cargo, reflecting dramatic shift in attitudes

January 9, 2017 — BEIJING — Air China has become the first airline in mainland China to ban shark fin cargo, marking a dramatic shift in attitudes toward trade in endangered wildlife here and throwing a lifeline to shark populations threatened with imminent extinction.

The news, released late Friday, came just a week after China announced plans to ban its domestic ivory trade, a landmark decision of vital importance in ending an epidemic of elephant poaching in Africa.

It marks the country’s gradual transformation from being the biggest source of the problem — as the largest market in illegal wildlife products — to becoming a major part of the solution.

“Scientists estimate that fins from up to 73 million sharks a year are used for shark’s fin soup, with much of the trade in shark fin destined for China,” said Alex Hofford, a wildlife activist from the conservation group WildAid in Hong Kong, which applauded Air China for taking “an ethical stance” to help protect sharks and oceans. “It’s a bold move, and this is likely to have a huge and lasting impact on shark populations and marine ecosystems worldwide.”

Hofford said the decision by China’s national flag carrier “puts FedEx to shame” — the U.S. multinational courier company has resisted repeated calls to take a similar step, despite a petition signed by 300,000 people, and an appeal from a coalition of animal welfare conservation groups who expressed concerns that its service could be used to carry fins of endangered shark species. That would be a violation of the Convention on Trade in Endangered Species (CITES).

Could a Partnership Born of Fish 2.0 Become the Red Bull of Seafood?

January 9, 2017 — There’s a global divide at the heart of the seafood industry: the businesses that most need new technologies are often continents away from the businesses creating them.

Small-scale seafood operations in Asia, Latin America, and Africa catch and farm most of the seafood we eat. Startups in the U.S., Canada, and Europe are developing most of the technologies that promise to improve logistics, traceability, fish feeds, and aquaculture production. But distance and limited resources mean these businesses rarely meet. Bridging this divide is an essential step toward both healthy oceans and a healthy, equitable food supply.

That’s one reason we open Fish 2.0 to a diverse range of seafood enterprises from around the world. The Fish 2.0 competition process not only helps ventures improve individually but builds trust and gives technology and product innovators the chance to find and connect with investors as well as other fishing businesses, seafood farmers, and technology creators. Finalists gain insights into parts of the supply chain previously hidden from them and are able to form relationships with like-minded entrepreneurs they otherwise would not have met. The result is new business partnerships that offer unique growth opportunities for investors, as well as solutions to the seafood industry’s most difficult problems.

Aquaculture innovators click

My favorite recent example is the new joint venture between 2015 Canadian finalist and track winner SabrTech and Thailand based runner-up Green Innovative Biotechnology (GIB). SabrTech’s RiverBox system reduces pollution from farm runoff and grows an algae-based feed from the captured wastewater. Bangkok-based GIB has developed a feed supplement that boosts the immune systems of farm-raised fish and shrimp, leading to higher growth rates, greater resistance to diseases such as early mortality syndrome, and lower feed costs. Both technologies solve aquaculture production and cost issues using naturally derived solutions.

Mather Carscallen, president and CEO of SabrTech, and Karsidete Teeranitayatarn, chief innovation officer of GIB, met during the pitch practice session for the Fish 2.0 finals at Stanford University last fall.  Mather helped Karsidete polish his delivery, and the two learned enough about each other to want to stay in touch.

Indigenous peoples of the world’s coastlines are losing their fisheries — and their way of life

December 5th, 2016 — The world loves seafood. According to some estimates, people consumed about 102 million tons of it last year.

A new study released Friday by the Nippon Foundation-Nereus Program, based at the University of British Columbia, shows that indigenous people who live on the world’s coasts are definitely hooked. They consume 15 times more seafood per capita than people in other parts of the world, about 2.3 million tons, or about 2 percent of the global catch, the study said.

They don’t simply catch and eat fish and other seafood. It’s the heart of communities, the center of culture and religion, a gift from the heavens. Seafood is crucial to the cultures of coastal indigenous people in the Americas, Asia, Africa and the Arctic, among other places, and overfishing and the ocean-wide movement of fish due to climate change could wipe those resources out.

On the coast of Africa at the equator, huge commercial ships are starting to encroach on native fishing areas as ocean stocks diminish. In places such as Madagascar, the stocks of community fisheries have been nearly lost.

“These big industrial fisheries are chasing the fish. In West Africa, larger vessels are moving closer and closer to shore,” said Andrés Cisneros-Montemayor, research associate at the University of British Columbia and an author of the study published in PLOS One. “A lot of these indigenous communities, all they have are dugout canoes.”

Why one lake contains more than 1000 species of the same fish

December 7, 2015 — The poster child for evolution may have finally revealed its secret. More than 1000 closely related but different species of cichlid fish live in Lake Malawi in south-east Africa – more than in any other lake in the world.

“They are remarkable,” says Christopher Scholz at the University of Syracuse in New York. The huge number of closely related species living together has meant they feature prominently in models of species diversification. But what made them so diverse has remained a mystery.

Some think environmental forces drove the diversification, others that the underlying cause was biological, says Scholz. For example, some females are colour-blind to males that are a different colour to them, which can drive sexual isolation between different groups of fish.

To try and settle the debate, Scholz and his team examined sediment records from the lake covering 1.3 million years. They found that over this period the water levels dropped by more than 200 metres around 24 times.

Forced diversification

These dramatic changes would have changed the habitat, says Scholz, as less water in the lake would shift the rocky shoreline inwards, alter the pH and salt levels of the water, and even separate the lake into smaller ones. This would ultimately force the fish to adapt to the new conditions and diversify.
