Can You Eat Ontario Crayfish?

Over 15 years have passed since this article was published. Some information might not be up to date anymore.

Officials are debating whether the rusty crayfish will become the next popular freshwater seafood dish due to its continued expansion on Lake of the Woods in Northwestern Ontario.

One member of the province Ministry of Natural Resources fisheries assessment unit for the lake yesterday claimed that eating a crayfish like a little freshwater lobster requires nothing more than boiling it.

Gavin Olson, a unit technician who has tried the occasional rusty crayfish from the lake, stated, “I’d recommend if anyone is interested in eating crayfish to try it.” They are explosive.

Rusty crayfish are not subject to any laws that restrict their possession or capture. But starting in 2007, the ministry will implement regulations making it unlawful for anglers to catch crayfish in Ontario and transport them to other lakes for use as bait.

Catching and using crayfish for bait in the same lake will be permitted. Additionally, the ministry will permit private fishermen who want to consume crayfish, particularly rusty crayfish, as well as commercial crayfish gathering for food.

Chris Brousseau, a senior fish biologist for the ministry in Peterborough, said that although it has been attempted, it is not yet very frequently used.

According to Tom Mosindy, manager of the Lake of the Woods fisheries assessment section, there are enough of them to be harvested here.

Success, however, would depend on how well people would accept a new local fish option.

How you can help

  • Learn how to spot rusty crayfish and how to stop this invasive species from mistakenly spreading.
  • Crayfish can only be used as bait in the body of water where they were originally caught. It is forbidden to move them over land. You are permitted to keep a total of 36 live crayfish at any given time.
  • If you have any information about the illegal importation, distribution, or sale of rusty crayfish, contact your local ministry office during regular business hours or immediately call the ministry tips line at 1-877-TIPSMNR (8477667) toll-free. Calling Crime Stoppers anonymously is also possible at 1-800-222-TIPS (8477).

The native northern clearwater crayfish (O. propinquus), the natural virile crayfish (O. virilis), and the introduced cryptic crayfish are all crayfish species that can be mistaken for rusty crayfish (O. obscurus). None of these species feature a rostrum that is pinched, black claw bands, or shell patches that are rusted.

What do Cajuns pronounce: crawfish or crayfish?

Well, Cher, technically speaking, both crawfish and crayfish are correct. It is not surprising that these Southerners have strong feelings about how the word is pronounced given that 98% of the crayfish consumed in the US comes from Louisiana crawfish farms.

Crawfish, sometimes known as “crawdads,” possess parasites that can severely infect both humans and animals with lungworm disease. It’s okay to consume cooked crayfish.

Crayfish as a meal

A buffet of crayfish is offered at the Tukkutorin kala restaurant in Kalasatama, Helsinki, Finland.

Everywhere in the world, crayfish are consumed. Like other edible crustaceans, a crayfish’s body is only partially edible. Most prepared foods, like soups, bisques, and etouffees, only include the tail section for consumption. Other parts of the crayfish, including the claw meat, may be consumed at crawfish boils or other banquets where the full body of the animal is served.

Larger boiling species’ claws are frequently split open to reveal the meat inside. Another favorite is to suck the crayfish’s head, as the boiled interior’s fat can accumulate seasoning and flavor.

The tiny lobster-like organisms that live in Nose Creek and the Bow River should not be cooked, a biologist advises.

You can collect crayfish in Calgary’s waterways for entertainment purposes only; you shouldn’t consume them.

Lesley Peterson, a provincial biologist with Trout Unlimited Canada, said that when it rains, all the storm water from many of these areas “essentially dumps right into Nose Creek and within not very long time, it is high and dirty.”

So everything that is on the streets, lawns, or rooftops, including soap, oil, chemicals, and lawn fertilizer, winds up in Nose Creek.

The creek, which drains into the Bow River not far from downtown Calgary, has been teeming with tiny freshwater lobsters that have been reproducing like bunnies.

And that is luring some city dwellers to catch them and cook them up, claims a recent Reddit post.

Are all crayfish edible?

The head and all of the crawfish’s body flesh are both safe to consume. The shell, tail, and antennae are typically not eaten. You should test the crawfish meat for safety if any of them perished before being boiled. Avoid meat that has become mushy.

In Ontario, are crayfish protected?

Rouge National Urban Park is a protected area by Parks Canada for various animal and plant species. The removal of any of the protected plants or animals from the Rouge is prohibited. Only individuals with specific licenses given by the Park Superintendent or the Province of Ontario may collect any plant or animal inside the park.

Without a scientific licence given by the Ontario Ministry of Natural Resources and Forestry, or by Parks Canada if the authorization is for use in Rouge National Urban Park, it is illegal to transport crayfish over land in Ontario, regardless of the reason for the transfer or the destination. Crayfish can be used as bait in the same body of water where they are caught by anglers with a valid fishing license from the province of Ontario. This is only allowed if they are used right away after being caught and aren’t moved first. They have to be used in the same body of water that they were collected from.

These regulations were put in place to reduce the possibility of the highly invasive Rusty Crayfish (Orconectes rusticus) spreading to other parts of Ontario. The Ohio River Basin in the United States is home to the rusty crayfish, which were originally noted in Ontario in the 1960s. Because they are bigger, more aggressive, and reproduce more quickly than their native counterparts, rusty crayfish are better able to defend themselves from predators and outcompete native crayfish for food and habitat. Even if one female bearing eggs is carried to another aquatic body, she alone can carry enough eggs to start an entirely new population. Females are able to carry hundreds of fertilized eggs under their tails.

In order to maintain environmental protection, Parks Canada keeps controlling invasive species like the rusty crayfish in Rouge National Urban Park. The Rusty Crayfish is an invasive species, and our team is working to raise awareness about it. We are asking for your help to stop it from spreading further. Please follow park rules so that everyone can take part in their favorite Rouge activities and the park’s fauna is kept safe.

Are land crayfish edible?

In ponds, lakes, streams, marshes, and other aquatic habitats, crayfish play a significant role as a favored food source for a variety of aquatic and terrestrial animals. Bullfrogs, egrets, herons, kingfishers, ducks, larger sportfish (trout, bass, and sunfish), and mammals (raccoons, otters, and mink) all eat a lot of crayfish. Crayfish contribute to the reduction of decaying debris and hence to the improvement of water quality since they will consume both living and dead plant and animal material. The majority of crayfish are not active predators and struggle to catch moving prey. Worms and insects that live in the bottom muds make up around 40% of their food. Aquatic vegetation, both alive and dead, makes up the remaining portion. In fact, crayfish have been proposed as biological waterweed pest treatments.

In addition to their significant ecological advantages, crayfish are also valued economically as laboratory organisms for biological research and as a commercially produced food item for human consumption. Freshwater crayfish are highly prized as a luxury food item in southern states, particularly Louisiana, and in European countries, such as France, despite not having the same widespread popularity as their saltwater relative, the lobster. Commercial trappers or rice field ponds are used in these regions to cultivate or collect wild crayfish. Every year, Louisianan crayfish farms harvest around 10 million pounds of red-swamp crayfish, which are worth $5 million. Fish bait frequently comes in smaller crayfish sizes. Even though practically all freshwater crayfish are edible and are regarded as table delicacies on par with lobster, man rarely uses them. Therefore, should you be fortunate enough to experience burrowing crayfish issues, simply eating them away would be an immediate cure!

Despite being important elements of aquatic ecosystems and a major economic resource, some species of crayfish that burrow can seriously impede man’s numerous uses of inland waters. As previously mentioned, large water losses may occur when earthen dams are weakened or water leaks are caused by the digging operations of burrowing crayfish. Crayfish frequently cause harm to agricultural crops, lawns, and gardens. Landowners who have spent the time and money to build small water impoundments should thus take some safety measures to guard against potential damage from burrowing crayfish. In order to take precautions, shorelines should periodically be inspected, especially those close to the dam, for the existence of high concentrations of crayfish and signs of extensive digging. Some crayfish species are well-known for digging, whereas others do not. Unfortunately, it is challenging to distinguish between crayfish that burrow and those that do not.

Are freshwater crayfish edible?

Many home cooks steer clear of buying and preparing live crabs and crustaceans due to a lack of knowledge on how to do so, fear of contracting a foodborne illness, or even a desire to avoid killing the animal during the cooking process. Because they are smaller and easier to handle than lobster and less likely to have food safety issues than shellfish, crayfish are a wonderful spot to begin your culinary journey. If you’re weak of heart, you can even buy frozen crayfish meat, but fresh crayfish provide the sweetest and juiciest meat.

Which crayfish species can you find in Ontario?

The Rusty Crayfish and the Obscure Crayfish are two crayfish species that are classified as Exotic by Canada. Both currently exist in Quebec after being imported as fish bait into Ontario. In Ontario, the rusty crayfish has expanded quickly, eradicating native crayfish from numerous lakes and rivers.

Does Ontario have blue crayfish?

For many years, we have been searching the Maitland River for queensnakes. In addition, we have been researching crayfish. The snakes’ virtually exclusive reliance on recently molted crayfish in their food is the cause of this. This occurs after mating once a year for adult males and numerous times a year for young, rapidly growing crayfish. In addition to the three native crayfish species in the river, we also keep a look out for the rusty crayfish, which is an invasive species. It’s good that we haven’t seen it yet.

Crayfish are often a dull shade of olive and brown, but every so often we get one that is a vivid sky-blue all over. This always prompts a discussion about the cause among the researchers. Is there a connection between it and their nutrition, their living situation, or another factor? This has been a mystery up to this point. A Queensnake Training Day was recently held, with the Maitland River serving as the site of the program’s practical component. They have to master the necessary protocols because there will be numerous teams of researchers investigating queensnakes in numerous different watersheds. Dr. Premek Hamr, the foremost authority on crayfish in Ontario, was in charge of the training’s crayfish component.

I couldn’t help but inquire about the blue crayfish while the “crayfish man” and I were wandering through the shallow water and looking for crayfish among the rocks. Premek answered that it was a very uncommon genetic characteristic, perhaps occurring once in a million. They are highly desired for aquariums, he added. A few steps later, I noticed a vivid blue claw on the river’s bottom. The other crayfish parts were discovered a minute later. Premek looked it over and said, “It’s a shame anything took it. In a tank, it would have been fantastic.” I now know more about one of the many intriguing creatures that inhabit the Maitland River.
