The Life History of Procambarus hayi

American Midland Naturalist, 1972
The- life history of Procambarus hayi (Faxon) was studied for 2 years near State College, Miss. Seasonal and temporal changes within the populations were determined from periodic field samples and laboratory observations. The known geographic range of the species was defined and its preference for lentic and sluggish lotic waters was in- dicated.

Ultrastructure of the sinus gland of the crayfish, Procambarus clarkii

General and Comparative Endocrinology, 1967
Abstract The crayfish sinus gland contains five types of granules (A, B, C, D, and E) which differ in electron density, shape, dimensions, and response to “staining” procedures for the electron microscope. It is suggested that each of these granule types, which are not mixed within individual axon terminals, may contain one of the six or more ...

Sex Recognition in the Crayfish Procambarus clarkii

Science, 1975
Male crayfish, Procambarus clarkii , show different behaviors toward males (aggression) and females (submission, courtship). Behavioral and neurophysiological tests with water in which the crayfish had been held demonstrated the existence of sex pheromones. The inner rami of the antennules are the site of reception,

Hemodynamics of the Crayfish Procambarus clarkii

Physiological Zoology, 1994
Crayfish (29.8 g) maintained at 25° C were examined with regard to their cardiovascular pressure-flow relationships. Pulsatile arterial hemolymph flows were simultaneously recorded in the three major arteries leading from the heart. Hemolymph pressures were measured throughout the cardiovascular system. Tail movements were also monitored.
