Compiled by Aquairi from published sources · Published · Updated
Overview
Peninsular Crayfish (Procambarus paeninsulanus) is a North-American freshwater crayfish of the family Cambaridae, listed in the Aquairi knowledge base as an intermediate-level species. North American Procambarus from Florida, brownish with cream highlights. Burrowing species, requires hideouts and substrate to dig.
Taxonomy
- Family: Cambaridae
- Genus: Procambarus
- Scientific name: Procambarus paeninsulanus
- Common synonyms: Peninsula Crayfish
Habitat
Procambarus is a North-American crayfish genus (Cambaridae) with hundreds of described species from the south-eastern United States, Mexico and the Caribbean. Many species occupy shallow ponds, ditches and slow streams; several have been introduced to Europe and Asia and are now widespread invasive species. The Aquairi knowledge base records this entry from: Florida (USA).
Tank requirements
- Minimum tank volume: 80 L (21.1 US gal)
- Adult size: 8-12 cm
- Temperature: 18-26 °C (64-79 °F)
- pH: 7-8.5
- GH: 8-18 °dGH
- KH: 4-12 °dKH
- Lifespan: 3-5 years
Diet
An omnivore. Diet includes plant matter, biofilm, algae, detritus and protein in the form of carrion, small invertebrates or fish remains. In the aquarium a daily portion of sinking pellet, regular blanched vegetables and occasional frozen bloodworm or shrimp meet nutritional needs and reduce intraspecific aggression.
Compatibility
Aggressive predator. Adults are large enough to catch slow bottom-dwelling fish, prey on dwarf shrimp and clip soft plants; a species-only or fast top-dwelling community is preferred. Suitable tank mates listed in the Aquairi knowledge base: Solo recommended. Should be kept away from: All fish, Shrimp, Snails, Plants.
Breeding
Reproduces in fresh water without a planktonic larval stage. After mating, the female carries the eggs glued to her pleopods for several weeks; hatched juveniles cling to the mother for additional moults before becoming independent. Stable water chemistry and abundant shelter for the brooding female are required.
Peninsula Crayfish Breeding Guide
Overview
The Peninsula Crayfish (Procambarus paeninsulanus, Faxon 1914) is a North American crayfish of the genus Procambarus, which is native to North and Central America with most of its diversity in the southeastern United States. It is recorded from spring-fed rivers of northern Florida, such as the Wakulla and Silver rivers, the Aucilla drainage, and adjacent counties of southern Georgia.
Sexing
As in other Cambaridae, sexes are told apart by the abdominal appendages: males carry modified front pleopods used to transfer sperm, while females have a sperm-storage structure (annulus ventralis) between the legs. Mature males are needed for fertilization, so a mixed group is required for reproduction.
Breeding Setup
This is a burrowing species, so the breeding tank should provide a deep substrate to dig and ample caves or pipe hides; firm hardness and neutral-to-alkaline water suit it. Plenty of separate retreats reduce aggression and give a berried female a place to seclude herself while she carries the clutch.
Berried Female & Young
Crayfish reproduction is direct: the female carries her eggs attached beneath the abdomen, and after hatching the juveniles cling to the same pleopods before becoming free-living. There is no aquatic larval stage to manage, which is typical for freshwater crayfish of this group.
Juvenile Care
Once the young leave the mother they feed as omnivores on detritus, biofilm and prepared sinking foods. Crayfish are cannibalistic when crowded, so juveniles need abundant cover and should be thinned out into separate grow-out space as they grow.
