Raising Blue Crabs In Freshwater

Raising Blue Crabs In Freshwater, The most effective way of catching blue crabs in freshwater is to first deal with the most common problem encountered by those who would capture them – their escape.

As one crabber stated: “If you can’t stop them from running away, then you might as well forget about catching any.”

But it can also be done with various kinds of traps and baits. And other methods are available that will result in dead crabs. It may even be possible to use saltwater bait if you intend to kill crabs, but this is a hazardous method.

Blue crabs can be kept alive and fresh in a bucket or even in the water for hours if they cannot escape.

1. Bait the crabs and keep them running with your finger in their mouth:

The secret behind this method is for you to keep the crabs running with your finger in their mouth.

If you are not careful, you may lose a finger if they snap shut or fall off the dock into the water. But that would not be a problem if you have another finger to replace it!

2. Keep them in a covered box:

This is a widespread and straightforward method. Collect as many crabs as you can hold in the box and keep them tightly shut inside for at least an hour.

This will give all of them a chance to relax, settle down and accept these new surroundings.

3. Keep them in a small bucket:

This is another common and very effective method. Place the crabs in a small bucket (or pail) and fill it with cold water.

Please make sure the crabs can’t jump out and seal the top with a piece of cloth and put them in a box to prevent them from escaping.

In about one hour, all of the crabs will settle down and stop moving around.

If you have never kept blue crabs in a bucket before, it’s OK to try this method but keep the lid loose so you can easily pick them up whenever needed.

But as things become more comfortable for them, the lid can be tightened and sealed off. It’s a good idea to have a small opening in the cover so they can breathe.

4. Keep them in a shallow pan of water:

If you have many crabs, this method is suitable for holding a lot of them. A small wooden crate is ideal for this purpose, but any shallow pan will do.

Just fill it with water and contain the crabs inside. This method works incredibly well in saltwater, where the abundance of crabs quickly overcomes any resistance they may have to be confined.

Rules for keeping blue crabs:

  • Blue crabs can be kept in a freshwater tank, as long as it is at least 5 gallons or larger.
  • You will need to make sure the water stays at a good level of cleanliness.
  • If you want to keep more than one crab, they must be put on opposite sides of the tank. This is because blue crabs may fight if placed near each other.
  • Blue crabs can be kept in a safe tank for one or two weeks.
