BUEU, Spain >> Whether it’s spiced in the Spanish style or sliced as Japanese sashimi, octopus as a dish is becoming a victim of its own popularity.

Prices for the tentacled mollusk have about doubled in the past two years due to a global boom in appetite for these classic dishes. And supplies have tightened, with fisheries not yet able to farm octopus and relying on ocean currents to yield a good harvest.

This year has been hard, with lower catches in major producing countries like Morocco and Spain.

“The price will rise even more,” says Carmen Torres Lorenzo, who has been selling fish for three decades in the market of Bueu in Spain’s northwestern region of Galicia, famed for its octopus dish. “I wish a lot of octopus would appear … and the price will come down, but that won’t happen.”

The price of a regular size, locally caught octopus has risen from $8 to $16 for 2.2 pounds in the last two years. The price is typically somewhat higher in other countries, like the U.S., that do not specialize in its fishing.

The Food and Agriculture Organization says prices are expected to continue to grow as demand has risen in all major markets, including Japan, the United States, China and Europe. Meanwhile, catches have been limited, even in the biggest producing countries, Morocco, Mauritania and Mexico.

Some scientists in Japan and Spain are working on techniques to farm octopus, but they are not ready yet for commercial purposes. Octopus eggs are laid on the ocean floor, where they are fertilized and transported by currents, a condition that is hard to reproduce in a controlled environment.

“There is a lot of demand for this product, and what we can offer is little, so the price skyrockets,” said says Jose Manuel Rosas, president of Bueu’s fishermen guild.

Increasing the fishing quotas is not an option, says Rosas. “This would kill the goose that lays the golden eggs. We have to pamper it, we have to take care of it. (Galician octopus) production is what it is.”
