The crustacean gill is a multi-functional organ, and it is the site of a number of physiological processes, including ion transport, which is the basis for hemolymph osmoregulation; acid-base balance; and ammonia excretion. The gill is also the site by which many toxic metals are taken up by aquatic crustaceans, and thus it plays an important role in the(More)
Crustaceans are a diverse and ancient group of arthropods that have long been studied as interesting model systems in biology, especially for understanding animal evolution and physiology and for environmentally relevant studies. Like many model systems, advances in DNA-sequencing methodologies have led to a large amount of genomics-related projects. The(More)
Inland shrimp culture is being practiced in several regions of the United States. In Alabama, the culture of shrimp (Litopenaeus vannamei) in inland low salinity well water (approximately 4.0 ppt) faces several challenges. The ionic composition of these waters is deficient in several key minerals, including potassium (K +) and magnesium (Mg 2+). The(More)
The Pacific white shrimp, Litopenaeus vannamei, acclimated to 30 ppt salinity, was transferred to either low (15 and 5 ppt), or high (45 ppt) salinity for 7 days. Hemolymph osmolality, branchial carbonic anhydrase activity, and total ninhydrin-positive substances (TNPS) in abdominal muscle were then measured for each condition. Hemolymph osmotic(More)
+ /K +-ATPase and other osmoregulatory genes in the gills of euryhaline 1 animals in response to salinity transfer: A meta-analysis of 59 quantitative PCR studies over 10 2 years 3 4 Abstract 24 Recent advances in molecular techniques have allowed gene expression in euryhaline 25 animals to be quantified during salinity transfers. As these investigations(More)
SUMMARY When transferred from 865 to 250 m-osmol salinity, the blue crab C. sapidus maintains its blood Na+ and Cl~ concentrations significantly above those in the medium. When branchial carbonic anhydrase is inhibited by acetazolamide, ion regulation fails and the animals do not survive the transfer. An alkalosis occurs in the blood at low salinity,(More)
Carbonic anhydrase (CA) activity was assayed in lysed erythrocytes and in branchial cytoplasm, mitochondria and microsomes of the channel catfish, Ictalurus punctatus. Branchial CA activity was highest in the cytoplasmic fraction, but activity was very low in mitochondria and microsomes. Erythrocyte CA activity was over four-fold greater than that in the(More)
Life originated in an aqueous environment, and extant aquatic species face special challenges due to the physics and chemistry of water. Such functions as feeding and digestion, waste excretion, ion and volume regulation, acid-base regulation, biome-chanics, gas exchange, responses to thermal changes, and reproduction are dictated by the constraints of(More)
