seasonal effects of leached mirex on selected estuarine animals.four 28-day seasonal experiments were conducted using selected estuarine animals in outdoor tanks that received continuous flow of mirex-laden water. mirex (dodecachlorooctahydro-1,3,4-metheno-2h-cyclobuta [cd] pentalene) leached from fire ant bait (0.3% mirex) by fresh water and then mixed with salt water was toxic to blue crabs (callinectes sapidus), pink shrimp (penaeus duorarum), and grass shrimp (palaemonetes pugio) but not to sheepshead minnows (cyprinodon variegatus), at concentrations le ...19751190846

biochemical and ultrastructural aspects of ca2+ transport by mitochondria of the hepatopancreas of the blue crab callinectes sapidus.mitochondria isolated from the hepatopancreas of the blue crab callinectes sapidus show up to 12-fold stimulation of respiration on addition of ca(2+), which is accompanied by ca(2+) accumulation (ca(2+):site = 1.9) and h(+) ejection (h(+):ca(2+) = 0.85). sr(2+) and mn(2+) are also accumulated; mg(2+) is not. a strongly hypertonic medium (383 mosm), mg(2+), and phosphate are required for maximal ca(2+) uptake. ca(2+) uptake takes precedence over oxidative phosphorylation of adp for respiratory e ...19744827906
calcium phosphate granules in the hepatopancreas of the blue crab callinectes sapidus.the hepatopancreas of the adult male blue crab callinectes sapidus in intermolt was found to contain substantial amounts of calcium, magnesium, and inorganic phosphorus, averaging about 260, 20, and 250 microg-atoms per g wet tissue, respectively, accounting for over 10% of the tissue dry weight. electron microscopy of the intact tissue showed three qualitatively different granular structures having electron densities suggestive of high mineral content. after fractionation of the tissue using ce ...19744827907

volume control by muscle fibers of the blue crab. volume readjustment in hypotonic salines.single isolated muscle fibers from the walking legs of the blue crab, callinectes sapidus act as boyle-van't hoff osmometers with an osmotically inactive volume of 33 %. fibers in hypotonic salines undergo a spontaneous volume readjustment toward the initial volumes of the cells found in isotonic salines. the volume readjustment is initiated by the increase in cell volume in hypotonic salines and appears to be dependent on the duration of exposure of the fiber to external sodium, the sodium conc ...19695767335

derived photosensitive pigments from invertebrate eyes.the red pigment in the eyes of the squid, blue crab, and horseshoe crab becomes photosensitive when treated with formalin, and bleaches in the light. the resulting change in density is approximately symmetrical around a maximum at 480 mmicro in the blue green. this difference absorption spectrum is in rough agreement with the spectral sensitivity of the cephalopod eye and differs only slightly from the difference absorption spectrum of vertebrate visual purple. the formalin-sensitized pigment is ...194319873349
