Red Swamp Crayfish

The Red Swamp Crayfish is a species of cambarid freshwater crayfish. It is also known as the red swamp crayfish, Louisiana crawfish, Louisiana crayfish or mudbug. It is native to northern Mexico, and southern and southeastern United States. But it has also been introduced elsewhere (both in North America and other continents), where it is often an invasive pest.

The Red Swamp Crayfish was probably introduced through aquaculture, because it is a popular food throughout the world. It has also been introduced outside it’s natural range to some countries in Asia, Africa, Europe and elsewhere in the Americas. Read some more information about this crayfish below.

Breeding
The Red Swamp Crayfish live in a variety of permanent freshwater habitats. They prefer ponds, swamps, marshes and slow moving rivers and streams. But they can also become established in lakes. They are especially well adapted to areas with large water level fluctuations. They generally mate in autumn and lay eggs in spring to early summer, in their native range. The females burrow into soft sediment and lay eggs. Depending on the size of the females, the number of eggs can vary. The large female Red Swamp Crayfish can lay as much as 650 eggs at a time.






Uses
The Red Swamp Crayfish is used and cultivated mainly for food.

Special Notes
The Red Swamp Crayfish is a very important species for commercial aquaculture, and it account for a large majority of the crayfish produced in the United States and elsewhere. In the 18th century, crayfish farming began in Louisiana. But total production of these species has decreased in recent years due to an increase of imports from China. And China is now the world’s leading producer of crayfish. It has also been introduced in many other places for cultivation, such as Spain.

Red Swamp Crayfish is eaten in the Caribbean, New Zealand, Canada, Thailand, Australia, Africa, China, Europe, Cambodia and the United States. And about 98 percent of the crayfish harvested in the United States come from Louisiana. However, review full breed profile of this crayfish in the table below.
