Regulation of the Acid-base Status during Environmental Hypercapnia in the Marine Teleost Fish
Specimens of Conger conger (L.) were exposed to environmental hypercapnia in a closed recirculating seawater system. Arterial plasma pH, Pco2 and bicarbonate concentration, as well as the net transfer of bicarbonate and ammonia between fish and ambient seawater, were monitored for 30 h of hypercapnia. The initial hypercapnia-induced reduction of arterial pH by about 0 4 pH units was restored to...
متن کاملThe acid-base responses of gills and kidneys to infused acid and base loads in the channel catfish, Ictalurus punctatus.
Acid and base loads infused into the dorsal aorta of the freshwater channel catfish (Ictalurus punctatus Rafinesque) were excreted by both gills and kidneys. The gills excreted 2-3 times as much as the kidneys. After a 2 mmol . kg-1 load of NaHCO3, the gills excreted 50% of the net OH- load in the first 5 h, while the kidneys excreted 18% in the first 6 h. After a 2 mmol . kg-1 load of NH4Cl, t...
متن کاملthe influence of corpus luteum on follicular fluid composition from different size follicles and their relationship to serum concentrations in sanjabi ewes
the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
Basal polarization of the mucosal compartment in Flavobacterium columnare susceptible and resistant channel catfish (Ictalurus punctatus).
The freshwater bacterial pathogen, Flavobacterium columnare, infects a variety of ornamental and farmed fish species worldwide through mucosal attachment points on the gill and skin. While previous studies have demonstrated a chemotactic response of F. columnare to fish mucus, little is known about how host gill mucosal molecular and cellular constituents may impact rates of adhesion, tissue in...
متن کاملChannel Catfish Ictalurus punctatus
We used a two-compartment, clearance volume-based model to examine rubidium and cesium Ž . pharmacokinetics in channel catfish Ictalurus punctatus after intravascular administration. We compared the apparent volumes of distribution in the central and peripheral compartments and the intercompartmental and whole-body clearances of both metals at 20.0 8C and 27.5 8C. Biological half-times of Rb we...
