More Ocean Critters You Can't Eat

Today Oceana published a report showing that three trawl fisheries, calico scallops, rock shrimp and royal red shrimp, pose an increased threat to South Atlantic and Gulf of Mexico deep-sea habitat.

  1. Calico scallops are smaller and less expensive than bay scallops.  Because calico scallops are harvested in vast quantities they are not shucked by hand but are steamed to open their shells. Calico scallop meat can be identified by its whitened edges which have been partially cooked by the steaming. Because of their size, taste, and quality they are generally cheaper.
  2. Rock and Red shrimp are far more perishable than other shrimp. Therefore, most are marketed in the raw frozen state as either whole or split tails. Rock shrimp are purchased according to size, however the largest size generally available is 21 to 25 per pound. They are also lower in price than other shrimp

So with respect to these avoid cheap shrimp and scallops.  Your best bit is to avoid supermarkets and head to an experienced fish monger or seafood shop where you can ask question about exactly what you are getting.  The minimum wage fish counter help at Stop and Shop doesn’t know or care.

He has conducted deep-sea research for 20 years and published over 50 papers in the area. He has participated in and led dozens of oceanographic expeditions taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (, a popular ocean-themed blog that has won numerous awards. His writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web. His forthcoming book, Science of the South (, connects cultural icons of South such as pecan pie with the science behind them.

  1. Good info for me since I like both of these. I am sure our Walmart stores would be one of those places who don’t know where they come from. Would it say calico scallops or red or rock shrimp on the bags any where?

  2. I love eating fishies. Is it okay to eat fishies from artificial pools?

    Do you know any site that lists environmentally friendly and unfriendly products?
