![]() However, another study, completed in 2015, showed that the particular practices of farming geoducks may have a negative impact on species, such as birds, since the netting used to protect geoducks also serves to protect the prey those birds might otherwise forage, such as small crabs. ![]() In fact, there’s evidence that geoduck farming may even work to recruit* eelgrass, an endangered species. One study showed no net negative ecological impacts of geoduck (although there has been a shift of species in areas with geoduck farms-for instance, halibut and flounder, which prefer uninterrupted bottom areas are scarcer, but other animals that like to congregate (and hide) around structures have increased in population). There have been some concerns, however, from environmentalists and property owners about the impacts of these geoduck farms on coastal ecology. The goal is to grab geoducks by their shell (so as not to damage the siphon) and then quickly wrap a rubber band around them to keep their shell closed. At that point, the geoducks are harvested by essentially super-saturating the surrounding sand with water and then extracting the geoduck by reaching one’s arm down into the pipe. Each pipe is seeded with a couple juvenile geoducks, which will remain in those pipes for a few years until they reach maturity (the exact timing of this depends on a number of factors, including water temperature). Geoduck farms may look like a bunch of pipes plunged into a beach, which at low tide, may be exposed. Like oysters, and many other mollusks, geoducks are a facet of the aquaculture/mariculture industry. Geoducks being held closed with rubber bands (Photo from USDA) If you’re diving, you might only see the siphon, which resembles certain types of sea sponge (such as Alpysina archeri). If you see one on the beach, in the wild, most likely you’ll notice it because it spurts a little fountain of water out occasionally, from its siphon. The meat from a geoduck tastes best when it’s cooked by boiling for about 20 minutes. Geoducks are large and have an interesting texture that people either love or hate. They are harvested and eaten in many different ways. It has a very long siphon, which it uses to filter water. Additionally, the pressure from the sand helps them keep their bivalve closed (the muscles which do this in other bivalves, like oysters, are not strong enough in geoducks to do this naturally). Geoduck is a type of clam that can be found in the Pacific Northwest. As they grow, they can bury themselves deeper, which provides additional protection from animals-including people-that might enjoy a tasty geoduck snack. When they begin to settle onto the substrate, they start to bury themselves, as deep as their siphons will allow. Geoducks, like other bivalves spend the first weeks of their life in a larval state, floating around on ocean currents. Like other bivalves, the geoduck filter feeds-which means it likely has some impact on water quality, although there don’t appear to be published studies on how much water an adult geoduck can filter a day or the degree to which it cleans the water relative to other bivalves. Lower a geoduck into the boiling water for 10 seconds, then ice it. It’s the Pacific geoduck (pronounced gooey duck Panopea generosa) clam, which has been reported to live more than 125 years. The average size of a geoduck is 2.07 lbs (0.94 kg) and the siphon can be as long as a baseball bat 2. Use a pot that’s large enough to hold enough water to cover an entire geoduck. ![]() You might imagine that leaves it vulnerable to predators because its tender parts are so readily exposed (tender parts that are, apparently, lightly sweet and crispy). 1.Fill a large pot with water, and bring it to a boil. There’s a marine clam so large that it can’t stuff itself in its shell. 663 views, 14 likes, 0 loves, 1 comments, 8 shares, Facebook Watch Videos from Geoduck from Canada: The tip of a Geoducks siphon from a divers perspective. you're in the presence of a geoduck when you spot two of its siphon holes.
