Black Mussels vs Green Mussels

If you love seafood, there is a high chance you know about mussels. They are popular dishes, owing to their amazing taste, availability, and nutritional value.

Mussels live in both freshwater and saltwater, making them widely available. It is, therefore, a common ingredient in several fine dining cuisines. A possible reason is their compatibility with several dishes.

If you are a fan of these mollusks, you know that there are several types. In this article, we will touch on black and green mussels to understand their differences.

Black Mussels Explained

We start by looking at black mussels, which are the most common type. Many people confuse them with blue mussels due to their similarities. Both are small and have elongated lips. Also, they have a rich ocean taste, though some people claim the black mussel is milder.

The main difference between the two is their colors. The blue mussel has a fading bluish hue, while the black one is entirely black, with a slight shiny tinge.

Black mussels inhabit the North Pacific, North Atlantic, and Arctic coasts. They are available in North America, Europe, and parts of Asia. On the Pacific Ocean side, their range extends from California to Alaska in the USA. In Asia, they are abundant in areas north of Hokkaido in Japan. On the North Atlantic side, they are present from Maine to Canada. Their habitat extends to Northwest Greenland.

The cool waters in these regions favor the growth of this seafood.

Farming

The rearing of black mussels is almost entirely natural. It involves the use of ropes, with juvenile mussels seeded into them. The vertically set ropes act as the substrate. The mollusks will grow on them, using their byssus threads for anchorage.

The rope length varies depending on food availability and water depth. As the black mussels grow naturally, farming them is pretty effortless. Typically, mussels take less than 2-years to develop fully. You harvest them at this point. For a sustained supply, you seed the ropes every month.

Black mussel farmers have to be vigilant against predators, especially in small-scale settings. Predators include sea birds, snails, and starfish. Otters, raccoons, and geese prey on freshwater mussels.

Characteristics

Black mussels are bivalve mollusks featuring two shells hinged together. A distinguishing feature of mussels is their asymmetrical and elongated shells. Their average length is 6-centimeters; however, some may reach up to 15-centimeters.

The fleshy interior has a creamy hue, with touches of silver on the outer edges. When cooked, the flesh takes on an orange-yellow appearance. The black mussel’s meat is tender, intense, and rich.

Availability and Cost

Farming black mussels is a simple task. Coupled with their wide distribution, they are available all year round. Easy access to this mussel type translates to affordability.

You get them in a preferred form, mostly fresh or frozen. Moreover, there are fully and half-shelled varieties. The former is common in restaurants and eateries, where you eat the flesh straight from the shell.

The shell-less type has no shell, only the flesh, which may be in a can or plastic wrapping. Often, such mussels have preservatives or marinade to improve their life.

Green Mussels

On the other side of our discussion, we have the green mussels – another common mussel type in the USA. It is native to New Zealand and the Indo-Pacific coasts.

Also known as the green-lipped mussel, it is easy to distinguish from the black mussel. It is larger, growing up to 6-inches long. At the lips, it is dark-green, with the color fading towards the hinges. Near the point of attachment, it has a brownish to a yellowish tinge.

These mussels prefer areas that are about 2-meters deep, with plenty of food.

Farming

While the green-lipped is native to New Zealand, countries like India and the USA rear them. However, farming of these mussels adheres to strict regulation and requires keen monitoring. Areas of concern are water and feed quality.

A possible reason for such a move is their fast growth rate. The mollusks grow fast and may outcompete other creatures. In addition, they are bottom feeders and can ingest toxins. The toxins can be hazardous when consumed by humans.

Characteristics

A distinguishing attribute of the green mussel is its color. It is green, with some parts appearing brown or yellow. The shell is smooth and firm. Also, compared to most mussels, the green-lipped is pretty large. On average, it can grow up to 6-inches.

On the inside, the shell has a silver to fading brown appearance. The flesh is firm, with a solid cream appearance. When cooked, it looks yellowish. The meat is chewy and tender but less intense than that of the black mussel.

Availability and Cost

Green mussels have a higher price tag than most mussel varieties. Among the reasons is its exclusive natural growth in New Zealand. As such, it may not be present at all times due to seasonal changes.

Furthermore, they are large, offering you a decent serving of its flesh – It is roughly twice as large as the black mussel.

You can find them frozen or fresh in the seafood market. Plus, there are the canned types, which may have preservatives. In restaurants, you may get the meat only, fully or half-shelled varieties.

Difference between Black and Green Mussels

An obvious contrasting point between the two mussel types is their appearance. Black mussels are dark, with a slight shininess. Their body is smooth and small, with many people suggesting that they resemble blue mussels.

On the other hand, green mussels are green at the lips. The color takes on a dull brown to a light shade of yellow near the hinges. They are also large. When put side to side with black mussels, the green mussels appear to be more prominent.

The other variation is the meat. Green mussels have more meat, but it is chewy. There is some tenderness to it, with the taste being mild. Some suggest that it is sweet. Black mussels have little flesh, described as somewhat rich to intense. It is tender but not chewy.

Many culinary experts vouch for black mussels, as their intensity makes them diverse. However, the green-lipped is also diverse, but not to its counterpart’s degree.

The black mussel is readily available as it inhabits different environments. They can live in saltwater and freshwaters. Farming them is effortless as it is a natural process.

Green mussels mostly occupy the Indo-Pacific regions, with large populations in New Zealand. Their range is increasing due to farming in countries like India. Rearing is subject to strict monitoring and regulations. The scarcity of green mussels reflects on their costly price tag. The black ones are readily available hence their affordability.

A similarity the two mussel varieties share is their packaging and presentation. You can get them fresh, frozen, fully-shelled, half-shelled, or meat only. In addition, there are canned varieties with a long shelf life.
