Mycoflora on the cuticle of the invasive crayfish Procambarus clarkii

Fundamental and Applied Limnology, 2012
A total of 18 genera and 22 fungal species was detected on adults of the red swamp crayfish Procambarus clarkii of both sexes collected in Lake Trasimeno from June 2007 to June 2008. The most frequent fungal species was Phoma glomerata, isolated from 67.82 % (N = 59) of the analyzed individuals.

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,

Eyestalk movements in the crayfish, Procambarus clarkii

Comparative Biochemistry and Physiology Part A: Physiology, 1985
Abstract 1. 1. Eyestalk movements of the crayfish ( Procambarus clarkii ) were recorded with a capacitative sensing device under various visual conditions. 2. 2. The eyestalk movements were conveniently classified into four types of visually evoked movement (tracking movement, optokinetic nystagmus movement, “on” movement, apparent movement ...

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.
