Celebrating Crustaceans

Here at SMELTS we are developing new technology to support Line-Less Crab and Line-Less Lobster Rafts.

Creating a sustainable method to help fishermen continue to collect crabs while minimizing the possibilities of entanglement is one of our missions. 

Let's take a moment and learn more about these incredible crustaceans.

Dungeness crab have an oval-shaped carapace that is yellow-brown to purplish. They have four pairs of walking legs and a pair of claws. The claws have light-coloured tips, sharp serated teeth and a pronounced hook at the tips, distinguishing it from similar species. Dungeness crab can weigh up to two kilograms and have a shell diameter exceeding 200 millimetres, but crabs of this size are uncommon because of the intensity with which they are fished. Read more.

Snow Crab

Snow crab, also referred to as Queen crab, are found in the North Atlantic and North Pacific oceans. In the North Atlantic, they are found from Greenland in the northeast Atlantic and from southern Labrador to the Gulf of Maine in the northwest Atlantic. They prefer deep, cold-water conditions. Canada is the world’s largest producer of Snow crab, accounting for about two-thirds of the global supply. In 2011, almost 73 percent of all snow crab exports from Canada were destined for the United States. China and Japan are also major markets.

American Lobster

Like other crustaceans, the American lobster has a hard exoskeleton, or shell. It is brown to olive green and may be flecked with red, orange or black. It is long-lived and can grow to lengths of 60 centimetres and weigh over 18 kilograms. It has a total of five pairs of walking legs, including the great claws, or chelipeds, as well as two pairs of antennae, an abdomen bearing feathery appendages known as pleopods, and a tail with a central telson and four fins called uropods. The American lobster molts many times during its lifetime, usually in warmer waters. Read more.

Callinectes sapidus has many names such as the blue crab, Atlantic blue crab, or regionally as the Chesapeake blue crab. This crab is a species of native to the waters of the western Atlantic Ocean and the Gulf of Mexico, and introduced internationally.

The Blue Crab is of significant culinary and economic importance in the United States, particularly in Louisiana, North Carolina, the Chesapeake Bay, and New Jersey. It is the Maryland state crustacean and is that state's largest commercial fishery. Read more.

Thanks for taking the time to learn more about these creatures. We are excited to continue working on our Line-Less technology to help fishermen and marine life alike.
