"aquaculture" news and stories

For a nice Catholic girl like moi, Lent means several weeks of fish-focused Fridays. Sometimes that means grabbing a fish sandwich on the run. While there's no shortage of fast-food spots ready to fill that need, it's not always clear what kind of whitefish is sandwiched between those seeded buns. Frequently it's made from swimmers like pollock, hake or, as Wendy's latest Lenten promotion brags, North Pacific cod. But plenty of fish sandwiches, fish sticks and fish-'n-chips are made with a fish you probably haven't even heard of: hoki.

Like many issues surrounding fish and sustainability, things are often complicated. Environmental groups like the Blue Ocean Institute and Greenpeace give New Zealand hoki (also known as blue grenadier, whiptail and blue hake) a poor rating.

"We're in the process of updating our hoki report now," says Alan Duckworth, research scientist for the Blue Ocean Institute, "but the biggest concern with hoki is very low abundance compared to what it used to be."

A fish better known for its contribution to the American songbook than the American dinner plate is being touted as a sustainable alternative to grouper and red snapper. Southern conservationists are now championing red porgy, the fish that was once so ubiquitous on low-country docks that it lent its name to the hero of George Gershwin's opera, "Porgy and Bess."

While the effort has been slightly hampered by chefs' reluctance to tinker with unfamiliar proteins and the lingering social stigma associated with eating red porgy, backers believe the fish's taste and history make it an excellent candidate to diversify coastal diets.
