Pacifastacus fortis (known as the Shasta crayfish or placid crayfish) is an endangered crayfish species endemic to Shasta County, California, where it is found and first described in 1914, only in isolated spots along the Pit River and Fall River Mills. [4] It is estimated that there are a total of roughly 4000 of the species still alive today. [5]
Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
In 1990, Louisiana produced 90% of the crawfish in the world and consumed 70% of it locally, [13] but by 2003, Asian farms and fisheries produced more, outpacing American production rapidly. By 2018, P. clarkii crawfish production in the Americas represented just 4% of total global P. clarkii supply. [14]
The signal crayfish (Pacifastacus leniusculus) is a species of crayfish indigenous to North America. Introduced to Europe in the 1960s to supplement the North European Astacus astacus fisheries, which were being damaged by crayfish plague , it was subsequently discovered that the signal was itself a carrier of that disease.

Procambarus clarkii, known variously as the red swamp crayfish, Louisiana crawfish or mudbug, [3] is a species of cambarid crayfish native to freshwater bodies of northern Mexico, and southern and southeastern United States, but also introduced elsewhere (both in North America and other continents), where it is often an invasive pest.
California produces almonds worth $5.3 billion every year. That is 100% of commercial almonds in the United States, 100% of all of North America, and 80% of commercial almonds around the world. Agriculture is a significant sector in California's economy, producing nearly US$50 billion in revenue in 2018.
The global annual production of freshwater prawns (excluding crayfish and crabs) in 2007 was about 460,000 tonnes, exceeding 1.86 billion dollars. [47] Additionally, China produced about 370,000 tonnes of Chinese river crab. [48] In addition astaciculture is the freshwater farming of crayfish (mostly in the US, Australia, and Europe). [49]
