Variations in serum constituents of the blue crab, Callinectes sapidus: glucose

AMESON MICHAELIS(MICROSPORIDA) IN THE BLUE CRAB,CALLINECTES SAPIDUS:PARASITE-INDUCED ALTERATIONS IN THE BIOCHEMICAL COMPOSITION OF HOST TISSUES

“…Plasma glucose concentrations in freshly collected Callinectes sapidus specimens are extremely variable. Our control blood-glucose values were at the high end of the reported normal range (Dean and Vernberg, 1956a;Lynch and Webb, 1973b). Elevated glucose concentrations may be due to handling stress (Telford, 1968), asphyxia (resulting from holding animals out of water) (Lynch and Webb, 1973b), or high temperatures (Dean and Vernberg, 1965b).…”

Parasitized blue crabs had reduced blood glucose levels during the terminal stages of microsporidan infection (a terminal hypoglycemia).…”

Biochemical studies on changes associated with enzymes of glucose metabolism in white spot syndrome virus (WSSV) infected with Penaeus monodon (Fabricius)

“…Hall and van Ham (1998) reported that blood glucose served as a simple and reliable index for biological stress for shrimp. Telford (1968) and Lynch and Webb (1973) also reported that stress affected qualitative and quantitative nature of circulating carbohydrates. Stewart and Cornick (1972) also observed disappearrance of glucose and lactic acid from the haemolymph of the lobster infected with Gaffkya homari.…”

“…Abdel Rahman et al (1979) and Lynch and Webb (1973) reported that efficient mechanism of glucose homeostasis is absent in crustaceans and they tolerate large variations in blood glucose. The reduction in the glucose level during infection might be due to stress and the resultant energy crisis.…”

Location, Location, Location: The Importance of Cull Ring Placement in Blue Crab Traps

“…Smaller crabs retained in traps are subject to increased mortality due to the cannibalistic and aggressive nature of crabs (Eldridge et al 1979;Smith and Hines 1991;McKenna and Camp 1992). In addition, handling of crabs and other decapods results in added stress and delayed mortalities even if the crab is removed from the catch and returned to the water (Lynch and Webb 1973;Guillory et al 2004). Crabs are also entrapped in lost or abandoned derelict (''ghost'') traps (Guillory 2001;Havens et al 2008).…”
