Crayfish can be cooked more humanely by first freezing them unconscious for a few hours, then destroying the central nervous system along their abdomen by cutting the crayfish lengthwise with a long knife down the center of the crayfish before cooking it. [46] Global crayfish production is centered in Asia, primarily China.
While most Americans eat them warm, the Swedes and Finns normally eat them cold after letting them sit in a brine over night. [5] One traditional Swedish and Finnish practice is to eat crayfish with a vodka or akvavit chaser. Most crayfish in Sweden are fished by professional fishermen or by lakeside property owners.
Some may even change sex during the course of their life. [32] Parthenogenesis is also widespread among crustaceans, where viable eggs are produced by a female without needing fertilisation by a male. [30] This occurs in many branchiopods, some ostracods, some isopods, and certain "higher" crustaceans, such as the Marmorkrebs crayfish.
Histotrophic (tissue eating) viviparity means embryos develop in the female's oviducts but obtain nutrients by consuming other tissues, such as ova or zygotes. [10] This has been observed primarily among sharks such as the shortfin mako and porbeagle , but is known for a few bony fish as well such as the halfbeak Nomorhamphus ebrardtii . [ 12 ]
Faxonius shoupi, the Nashville crayfish, is a freshwater crustacean native to the Mill Creek Basin in Nashville, Tennessee. [2] Prior to August 2017, the species was called Orconectes shoupi . [ 4 ] Faxonius shoupi is protected under the Endangered Species Act (ESA) as an endangered species.
At both sides of their mouths their lips interlock, which allows them to use suction feeding. [7] They are carnivorous creatures and will eat almost anything they can get into their mouths. Typically they prey upon animals such as insects and their larvae, [18] mollusks, annelids, crayfish, [19] small fish, amphibians, earthworms, and spiders ...
The diet of the freshwater crayfish varies with age, but predominantly consists of decaying wood, leaves and their associated microbes. They may also eat small fish, insects, rotting animal flesh and other detritus when available. [2] A. gouldi is very long-lived, surviving for up to 60 years. It has previously been reported to attain weights ...
Procambarus zonangulus, the white river crawfish, [4] white river crayfish [5] or southern white river crayfish, [1] [6] is a species of freshwater crayfish. It is a distinct but closely related species from Procambarus acutus , which is also known as white river crayfish and has a wider range.
