A topic that rarely, if ever, has made our pages, the sea cucumber’s moment in the spotlight has arrived:

Are Sea Cucumbers a Cleanup Solution to Fish Farm Pollution?

Seafood farm operators are breeding and deploying sea cucumbers to vacuum up the massive amounts of fish waste that pose a major problem for their industry. It is part of an effort to redesign fish farms with multiple species so that they work more like natural ecosystems.

Off the coast of the Hawaiian Island of Kauai, an underwater metropolis bustles. Sea turtles glide lazily through the surf while schools of fluorescent yellow butterflyfish weave between basketball-size sea urchins and sharp corals.

But Dave Anderson isn’t distracted by the otherworldly charm of the coral reef — he’s here on a mission. Around 70 feet below the surface, he finds his prize: a red sea cucumber. Continue reading →

Sustainable Seafood, from Dock to Dish

You’ve heard of farm-to-table. At its heart, farm-to-table means that the food on the table came directly from a specific farm. Also emphasizes a direct relationship between a farm and a restaurant or store. The vocabulary of the movement is changing now to include produce from the seas, giving birth to the concept of dock to dish.

The pile of fish marks an important step toward a fundamentally different way that prominent chefs are beginning to source American seafood: the restaurant-supported fishery. Call it an evolutionary leap from community-supported-agriculture programs, which support local farmers, and community-supported fisheries, which support small-scale fishermen. Both models rely on members who share the risks of food production by pre-buying weekly subscriptions.

What’s Behind the Prawn Sandwich?

A swelling appetite for shrimps and prawns in America, Europe and Japan has fuelled industrial farming of shellfish in the past few decades. The industry now has a farm-gate value of $10 billion per year globally and the prawn in your sandwich is much more likely to have come from a pond than from the sea. While the industry is dominated by the likes of China, Vietnam and Thailand, a large number of other countries have invested heavily in cultivation too.

 One is Sri Lanka, which saw the industry as a passport to strong economic growth and widespread employment. Just outside the world’s top ten producers, it accounts for approximately 50% of the total export earnings from Sri Lankan fisheries. More than 90% of the harvested cultured prawns are exported, going mostly to Japan.

Prawn aquaculture has been likened to slash-and-burn cultivation—find a pristine spot, remove the vegetation and farm it for a few years before moving on. But the analogy is misleadingly benign. Slash-and-burn systems on a small scale can be sustainable, since the cut plots can recover afterwards.
