Carotenoids of Cavernicolous Crayfish

Science, 1964
Small amounts of β-carotene and lutein were found in Orconectes pellucidus pellucidus . Cambarus bartonii tenebrosus from the same cave contained much less carotenoid than surface crayfish. Astaxanthin, the principal carotenoid of most Crustacea, was absent from O. p. pellucidus

Procambarus clarkii (Girard, 1852) and crayfish plague as new threats for biodiversity in Indonesia

Aquatic conservation, 2018
Numerous freshwater crayfish species are known to become successful invaders when introduced to new territories. One of the most invasive species in this group is the red swamp crayfish, Procambarus clarkii (Girard, 1852).

Crayfish extinctions and crayfish plague in central Ireland

Biological Conservation, 1988
Abstract The white-clawed crayfish Austropotamobius pallipes (Lereboullet) has been losing ground in Western Europe but remains widespread in Ireland, whose stocks are well-studied and of European conservation importance. Crayfish fungal plague, fatal to white-clawed crayfish, has affected all other European countries; it was first diagnosed in an ...

Crayfish and Drosophila NMJs

Neuroscience Letters, 2020
Many synaptic studies have utilized the experimental advantages of the Arthropod NMJ and the most prominent preparations have been the crayfish and Drosophila larval NMJs. Early cellular studies in the crayfish established the framework for later molecular studies in Drosophila.

Crayfish immunity – Recent findings

Developmental & Comparative Immunology, 2018
Freshwater crayfish is an important commodity as well as a successful model for studies on crustacean immunity. Due to the ease with which they are kept and the available methods for hemocyte separation and culture they have proven to be very useful.

Curve Walking in Crayfish

Journal of Experimental Biology, 1996
ABSTRACT Curve walking of crayfish Astacus leptodactylus was investigated by exploiting their optomotor response. The animal walked while spatially fixed on a motor-driven treadmill and turning behaviour was induced by an optical stimulus, a pattern consisting of vertical stripes moving in a horizontal direction.

Architectonics of crayfish ganglia

Microscopy Research and Technique, 2003
AbstractThe central nervous system of crayfish consists of a chain of segmental ganglia that are linked by cables of intersegmental axons. Each ganglion contains a highly‐ordered core of longitudinal tracts, vertical tracts, commissures, and synaptic neuropils.
