Academic literature on the topic 'Crayfish pond'

It is aimed to inoculate the species called Turkish crayfish (freshwater crayfish) in the artificial ponds located by the Fırat River in Surtepe village of Birecik district and to provide training to the disadvantaged groups selected from the region on the fishing of these crayfish and to provide new skills and income to the target groups. The species called Turkish crayfish (Astacus leptadactylus) will form a permanent population in the vaccinated ponds. With the crayfish vaccination practice, the suitability of crayfish breeding to the region and climate will be proven and the breeding of this species will be developed.

Crayfish have been in demand as desirable food items around the globe for centuries, and entrepreneurs have capitalized on this demand by developing and applying aquaculture principals for the intentional culture of this freshwater crustacean. The current state of the art has advanced within the last half century and is centered on a handful of species, represented by three different families, with some level of commercial production occurring on all continents except Antarctica. Procambarus clarkii (family Cambaridae), a native of south central USA, is cultured in the USA and China and easily forms the bulk of farm-raised and wild-captured crayfish globally. One North American species (Pacifastacus leniusculus) and two European species (Astacus astacus and A. leptodactylus) constitute the main cultured species from the family Astacidae and are grown in small operations throughout Europe and parts of Asia. Four species (Parastacidae), all natives of Oceania, are cultured in their native ranges and were also introduced for aquaculture in several locations around the globe. Cherax destructor and C. albidus, both commonly referred to as yabby, are medium-size crayfish and share similar life histories, whereas C. quadricarinatus (redclaw crayfish) and C. cainii (smooth marron) are larger and more valuable but have very different geographical origins. While commercial crayfish aquaculture is typically based on an extensive or semi-extensive production approach in earthen ponds, more intensive approaches may involve selective breeding, improved strains, brood or nursery phases, and use of raceways or recirculation systems. Pond size can range from 0.05 to 80 ha, depending on the species cultured. Harvesting is accomplished mainly by baited trap, although other gear and techniques are sometimes employed. Global crayfish aquaculture production has expanded significantly in the last decade, due largely to the integration of Procambarus clarkii with that of rice production in the USA and China. This integrated system of production works well because rice farming has similar requirements as crayfish aquaculture, such as clay soils, irrigation systems, and suitable climates; furthermore, the rice crop residue provides the base of the food web for furnishing sustenance to growing crayfish.

Abstract Crustaceans are aquatic arthropods that grow in steps rather than continuously by moulting (i.e. by replacing their exoskeleton). Although they are taxonomically highly diverse only few species from the order Decapoda are used for commercial seafood production. Small crustaceans from the order Branchiopoda are used as live food in aquaculture hatcheries. Aquaculture of crustaceans is mostly based on semi-intensive pond culture that utilizes coastal wetlands and has been developed unsustainably during the initial period of rapid growth. Crustacean aquaculture ranks second after fish in terms of value and third after fish and molluscs in terms of production yield. The Western whiteleg shrimp (Litopenaeus vannamei) accounts for more than half of all crustacean aquaculture. Other important species include euryhaline crabs, freshwater prawns, and freshwater crayfish. Shrimps and prawns develop by succession through planktonic nauplius, zoea, and mysis larval stages, while crab development includes planktonic zoea and megalopa larval stages. However, crayfish lack any planktonic larval stages, which simplifies their culture. Hatcheries operating in intensive production mode and nurseries producing juveniles are increasingly utilized for aquaculture of crustaceans before transferring juveniles to grow-out systems. Opportunities for increasing the ecological sustainability of crustacean aquaculture include utilization of recirculating aquaculture systems (RAS) for grow-out, reduction of water used by semi-intensive pond aquaculture, treatment of waste and sludge generated in aquaculture ponds instead of disposal into wild habitat, increased utilization of by-products, improved polyculture systems, increased biosecurity, and utilization of indigenous species.

The article presents the results of commercial cultivation of Australian red-clawed crayfish in the Astrakhan region in different years. The paper evaluates the productivity and mass of commercial crayfish. The differences in the results of cultivation in the same ponds when using feed and on a natural feed base are given.
