Blue Crab Facts

The blue crab is one of the most important crab species in the United States and there is an extensive fishery based around this tasty crustacean.

Where do blue crabs live
Distribution
The blue crab is native to the western edge of the Atlantic ocean (including the gulf of Mexico) from about Nova Scotia in Canada through to Argentina. Overfishing has caused the population boundaries to decline somewhat, but they are still regularly encountered within these areas. Unfortunately the blue crab has been introduced into Japan and European waters possibly through the ballast water from ships.

Habitat
Blue crabs are found in brackish water near the mouths of rivers and they spend most of their time in muddy shores and bottoms.

Fishing for blue crabs
In certain states of the US fishing for blue crabs is a popular pastime and like other crabs the best way to capture a feed is by using a crab pot of some form with a tasty bait inside. They can also be caught using dip nets (to scoop the crabs up) and on handline by gently lifting the crab to the surface. One of the most popular baits is chicken , but any fresh fish bait will also catch crabs. Many serious crabbers have their own favorite baits, which are a closely guarded secret.

It is easy to tell between a male and female crab. You simply turn the crab over and look at the apron (see pictures)






Always check your local crabbing regulations.

What do blue crabs eat?
Like most crabs blue crabs are omnivores (and not that picky I might add). They eat both plants and animals and prefer their animals as fresh as possible.

Eating qualities
Like most crabs the blue crab makes superb eating and requires only a simple cooking method and the slightest of seasoning to make a delicious meal.

Interesting blue crab facts

• They can deliver an extremely painful pinch and are noted for being particularly aggressive (even out of the water) and difficult to handle safely.
• A mature fertilized female produces about 2 million larvae.
  
• Blue crabs malt at various stages during their life cycle.
• You can also tell the sex of a blue crab via the color of its claws.

Where do sharks live

Sharks hold a certain fascination for many people and I have been pleasantly surprised by the amount of people visiting my shark posts so far. I have been watching some of the shark week on the discovery channel lately and I thought I would share some of what I have learned.

Where do sharks live?
Contrary to popular belief sharks are only found in 30% of the world oceans making 70% shark free. However, most coastal areas will be home to at least one species of shark. Research shows that sharks cannot live in water deeper than 1500 meters and this makes them susceptible to overfishing.

Great White Sharks are found in almost all coastal waters with temperatures from 12 and 24° C. There are large concentrations in Australia, South Africa and California.

Tiger sharks can be found close to the coast in almost all tropical and sub-tropical waters and will sometimes stray into temperate and cool waters.

Mako sharks are found in almost all tropical and temperate waters worldwide.

Interesting shark facts

• The bull shark is well known for its ability to live in both fresh and salt water - imagine the surprise if one made its way into your local bass lake!
• In the 16th century sharks were usually referred to as "sea dogs"
• Sharks never stop swimming, even to sleep, otherwise they would fall to the sea floor.
• Black-tip reef sharks have swum the Suez canal to colonize the Mediterranean Sea.
• While snorkeling in Australia, Luke Tresoglavic was bitten by a small wobbegong that didn't let go. He had to swim to the shore and drive to get help with the shark still attached to his leg.
• During an experiment a scientist plugged on nostril of a shark - it swam in a circle.

Fishing
Sharks are susceptible to overfishing and many species are now on the endangered list. As you might expect sharks are very good fighters and can grow to enormous sizes. Some sharks are also good eating. However the fact that they are under so much fishing pressure and can be downright dangerous near a boat means that you should think carefully before purposely targeting sharks.
