Prophenoloxidase system activation in the crayfish Procambarus clarki

Developmental & Comparative Immunology, 1993
The prophenoloxidase system (proPO) was studied in primary cultures of hemocytes of the crayfish Procambarus clarki. Both zymosan and lipopolysaccharide (LPS) separately induced rapid degranulation and lysis of semigranular hemocytes, with concurrent release of proPO.

Population dynamics of Procambarus clarkii (Girard) and Procambarus acutus acutus (Girard) (Decapoda: Cambaridae) in commercial ponds

Aquaculture, 1989
Abstract Population dynamics of red swamp crayfish, Procambarus clarkii, and white river crayfish, Procambarus acutus acutus, were studied in two commercial ponds in southern Louisiana during one production season. Recruitment, growth, mortality and reproductive development of both species were surveyed from September through the following May ...

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 ...

Simultaneous determination of 16 herbicides in Procambarus clarkii

Food Chemistry
This study is focused on developing a sensitive and reliable analytical method for determining 16 herbicides in Procambarus clarkii using pass-through solid phase extraction coupled with high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS).

Light adaptation in the photoreceptor of the crayfish, Procambarus clarki

Vision Research, 1968
Abstract Receptor potentials of retinular cells in the eye of the crayfish, Procambarus clarki, were studied with the aid of microelectrodes. Recordings were obtained with the eye excised using intracellular leads or with the eye in situ, using an extracellular approach.

Hypoxia adaptation in the crayfish procambarus clarki

Comparative Biochemistry and Physiology Part A: Physiology, 1984
Abstract 1. 1. P. elarki is an oxyconformer, with an oxygen uptake rate of 144 ± 4 μl/g wet wt/hr at oxygen tensions above 90% saturation and an uptake rate of 18 ± 3 μl g wet wt/hr at 15 torr. 2. 2. Between 159 and 40 tort, blood pH decreases slightly from 7.77 ± 0.03 to 7.65 ± .04, and at 15 torr, blood pH drops to 7.36 ± 0.06. 3. 3. At

Subunits and Cooperativity of Procambarus clarki Hemocyanin

1991
Arthropod Hcs are comprised of six, or multiples of six subunits. For dodecameric and larger Hcs, it has recently been postulated that cooperative interactions between the hexameric structures must be taken into consideration in describing their cooperativity (1–3).
