#astacidae
- Astaciculture — A specialized branch of aquaculture and zootechnics dealing with the study, breeding, controlled growth, and commercial exploitation of freshwater crayfish (crustaceans of the Astacidae family); this technological process includes setting up artificial hatcheries, optimizing water quality, controlled feeding, and ecological species selection for economic capitalization or restocking natural hydrographic basins.
- Astaco- — A scientific combining form (prefixoid) extracted from the Greek language (from 'astakos'), used in rare scientific, zoological, and paleontological terminology to refer to crayfish, decapod crustaceans of the Astacidae family, or to describe anatomical and fossil structures belonging to or closely related to this group of aquatic organisms.
- Fossilized crayfish — The fossilized remnant, petrified imprint, or petrographic cast of a prehistoric crayfish or a part of the exoskeleton of a decapod crustacean from the Astacidae family; these structural fossil formations are used in stratigraphical geology as biofacial indicators for reconstructing ancient freshwater aquatic environments.
