The long-term effects and detection ranges of passive integrated transponders in white-clawed crayfish Austropotamobius pallipes
This is an Open distribution, Abstract – Individual identification of the endangered white-clawed crayfish (Austropotamobius pallipes) can provide valuable information when assessing long-term survival of animals released into the wild; currently the most effective method is the use of passive integrated transponders (PIT) tags. A 360 days ex situ experiment was undertaken on 20-month, captive-...
متن کاملThe British freshwater crayfish Austropotamobius pallipes
lives in streams or pools that are liable to dry up or become stagnant, and these animals are known to leave water voluntarily to forage or to invade neighbouring habitats (Huxley, 1896; Taylor and Wheatly, 1980). When placed in air, the gills collapse and the crayfish suffer continuously from systemic hypoxia and hypercapnia. Associated with an initial virtual anoxia and a switch to anaerobic ...
متن کاملResistance to the crayfish plague, Aphanomyces astaci (Oomycota) in the endangered freshwater crayfish species, Austropotamobius pallipes
The pathogen Aphanomyces astaci Schikora 1906 is responsible for the decline of the native crayfish species of Europe, and their current endangered status. This pathogenic species is native to North America and only colonizes aquatic decapods. The North American crayfish species have a high resistance to this pathogen, while species from other regions are highly susceptible. However, recent fie...
متن کاملThe electrical potential difference across the epithelium of isolated gills of the crayfish Austropotamobius pallipes (Lereboullet).
There has been a considerable amount of work on the electrical potential differences and active transport processes of ions across various vertebrate epithelia (Ussing, i960). Little work of this type has been attempted on invertebrate material. As the crustacean gill epithelium has only a single layer of cells separating the body fluid and the external medium, it should be particularly suitabl...
متن کاملRespiration in relation to ion uptake in the crayfish Austropotamobius pallipes (Lereboullet).
1. O2 uptake was determined for periods of 23-46 h in salt-depleted crayfish held in deionized water (DW) or Na-free media at 10 degrees C. These media were replaced by artificial lakewater media (ALW) containing 0-2-0-6 mM Na and O2 uptake was again determined for periods of 24-66 h. 2. During net ion uptake in ALW the metabolic rate was either elevated or depressed. Standard metabolism in ALW...
