The Florida crayfish is a native crayfish, and FWC lets you keep it in a home aquaponics system without a permit and collect it locally. Beyond that, no UF/IFAS, FWC or SRAC document on raising it was found, so its temperature, feeding and breeding sections are left blank here. The usual ways to go wrong are selling animals without an FDACS Aquaculture Certificate and collecting a protected crayfish by mistake.1, 2, 5

Our reading of the temperature facts below against UF/IFAS's three regions (North Florida north of State Road 40, Central between 40 and 70, South below 70). A tank with a heater, a greenhouse or a shaded sump changes the answer.
FWC's "Aquaponics Licenses & Permits" page lists "Florida crayfish (Procambarus alleni)" as a "Native species that may be used without permit in personal systems" and says it "Can be harvested from local areas" (page shows no revision date; read 2026-11-02). The species does not appear on FWC's "Conditional Nonnative Species List" or "Prohibited Nonnative Species List" (both pages show no revision date; read 2026-11-02).
Permit or certificate
None for a personal system, per the FWC aquaponics page, which also says "No permit needed if aquatic species are produced for personal use only (not sold) and acquired in Florida". For commercial systems the same page says "An Aquaculture Certificate of Registration is required for use in commercial systems"; the certificate is issued by the FDACS Division of Aquaculture.
Selling fish or fingerlings
FWC's aquaponics page says the FDACS Aquaculture Certificate of Registration covers "production and sale of aquatic animals (fish, crayfish, prawns) by commercial businesses or private individuals", and that an FDACS Division of Food Safety food permit is needed if selling products for human consumption. FDACS-P-01770 Rev. 12/25 says anyone operating an aquaponic facility as a business "producing and selling aquatic animals must apply for an Aquaculture Certificate of Registration."
Also
Collecting: FWC's freshwater fishing FAQ says "There are no seasons, gear, bag or size limits for freshwater crayfish," and no recreational or commercial license is needed, but "It is illegal to take Florida's state-listed crayfish (Panama City, Sims Sink and Black Creek crayfishes)" and "all cave-inhabiting crayfish" (page shows no revision date; read 2026-11-02). Release: the FWC aquaponics page says "Aquatic species that are left over from aquaponics projects may not be released into Florida waters."
Rules change and this is a summary; the agency page in the sources is the authority. Check it before you buy, breed or sell.
FWC allows this species in personal aquaponics systems without a permit, but that is a legal statement, not a growing guide. Neither SRAC 454 nor SRAC 5007, the two aquaponics fact sheets fetched, mentions crayfish, and no UF/IFAS or SRAC document on keeping this species was found.
What this page doesn't cover yet
No UF/IFAS EDIS, FWC or SRAC document describing the biology or culture of Procambarus alleni was found; searches turned up only Wikipedia, USGS, US Fish and Wildlife Service and aquarium-trade pages, which are not allowed sources. Temperature, regions, growing, breeding and eating are therefore null.
No allowed source links the name 'blue crayfish' to Procambarus alleni or describes its colour; the alias comes from the task. EDIS FA195 (fetched) shows an 'electric blue crayfish' among Florida aquaculture products but does not name the species, so it is not used here.
FWC's crayfish research page (https://myfwc.com/research/freshwater/invertebrates/crayfish/) was fetched but covers only the Black Creek crayfish.
The FWC aquaponics page does not say whether crayfish bred in a home system may be given away or traded without a certificate.
FAO 'Small-scale aquaponic food production' could not be fetched (HTTP 403 on every FAO URL tried).
Every fact above is restated in our own words from these documents, written 2026-11-02. Independent of the University of Florida and of every agency named.
