Abstract
Presence of the Australian redclaw crayfish Cherax quadricarinatus (von Martens, 1868) (Parastacidae, Astacoidea) in a freshwater system in the Caribbean drainage of Costa Rica
Highlights
Freshwater crayfishes represent more than 600 species naturally occurring worldwide except in continental Africa, the Indian-subcontinent and Antarctic, and every year more species are being described (Crandall and Buhay 2008; Loughman et al 2017; Lukhaup et al 2017; McCormack and Ahyong 2017; Schuster and Kendrick 2017)
The present study reports on the first record of C. quadricarinatus inhabiting a natural freshwater system on the Caribbean drainage of Costa Rica, with voucher specimens having been deposited at a museum
Sampling was carried out during a nocturnal biological survey developed as a Cherax quadricarinatus in Costa Rican Caribbean drainage complementary activity for a course of Servicios y Actividades Ecoturísticas of Escuela Técnica Agrícola e Industrial (ETAI)
Summary
Freshwater crayfishes represent more than 600 species naturally occurring worldwide except in continental Africa, the Indian-subcontinent and Antarctic, and every year more species are being described (Crandall and Buhay 2008; Loughman et al 2017; Lukhaup et al 2017; McCormack and Ahyong 2017; Schuster and Kendrick 2017). The species has been reported in many countries, such as South Africa, Swaziland, Italy, Israel, continental USA, Mexico, Ecuador, Puerto Rico, Argentina, New Caledonia, China, Taiwan, Japan, Malaysia, Singapore and Indonesia There are currently two non-native crayfish species introduced into Costa Rica: the red swamp crayfish Procambarus clarkii (Girard, 1852) introduced in 1966 and presumably occurring in most Costa Rican regions (Huner 1977; Cabrera Peña 1994), and C. quadricarinatus, introduced in 1985 and present in the northwestern Pacific drainage The present study reports on the first record of C. quadricarinatus inhabiting a natural freshwater system on the Caribbean drainage of Costa Rica, with voucher specimens having been deposited at a museum
