(n.) A name given in the United States to various species of siluroid fishes; as, the yellow cat (Amiurus natalis); the bind cat (Gronias nigrilabrus); the mud cat (Pilodictic oilwaris), the stone cat (Noturus flavus); the sea cat (Arius felis), etc. This name is also sometimes applied to the wolf fish. See Bullhrad.

(6) From these results we conclude that: adaptation in the catfish retina includes two components: a) a lateral shift of the voltage-intensity curve along the intensity axis, and b) changes in the time course of light-evoked response.
(7) In olfactory neurons isolated from the channel catfish, Ictalurus punctatus, stimulation with olfactory stimuli (amino acids) elicits an influx of calcium that leads to a rapid increase in intracellular calcium.
(8) ), an inhibitor of GSH biosynthesis, did not deplete hepatic GSH in channel catfish.
(9) Our objective was to identify VG in the channel catfish, Ictalurus punctatus.
(10) The endocrine pancreas of the bullhead catfish, Ictalurus nebulosus, and the channel catfish, I. punctatas was studied by light and electron microscopy.
(11) Anoxic incubation for varying periods of Isoparorchis hypselobagri from the swim bladder of the catfish Wallago attu, led to an accumulation of oxygen debt on the part of the parasite.
(12) This indicates that the neural representation of the external body surface of the channel catfish faces caudally in the FL.
(13) An estimate of the total mass of bone in the Channel catfish Ictalurus punctatus Rafinesque, was obtained by dissection.
(14) Taste receptors for L-alanine and L-arginine in the channel catfish, Ictalurus punctatus, are differentially reactive to N-ethylmaleimide (NEM) and p-chloromercuribenzenesulphonic acid (pCMBS).
(15) Blood cells from Baltic salmon, Salmo salar, three-spined stickleback, Gasterosteus aculeatus, eel pout, Zoarces viviparus, crucian carp, Carassius carassius, African catfish, Clarias gariepinus, and reedfish, Calamoichthys calabaricus, were incubated with tritiated 11 beta-hydroxyandrostenedione (OHA) or 11-ketoandrostenedione (OA).
(16) Catfish GH and PRL were identified by Western blotting with antisera against chum salmon GH and PRL.
(17) The cellular requirements for channel catfish MLR responses were assessed by using three functionally distinct leucocyte subpopulations isolated from the PBL.
(18) The Indian catfish, Heteropneusted fossilis, was chemically thyroidectomized with thiourea.
(19) Neither the concentrations of these three brain tissue substrates, nor L-GDH activity were significantly different between fish at the two locations even though the observed UIA concentrations were equivalent to concentrations which have been observed to increase glutamine concentration in brain tissue of catfish during exposures under laboratory conditions.
(20) Results from oral dose studies indicated that SDM is readily absorbed from the gastrointestinal tract in channel catfish and distributes rapidly to body tissues, primarily the muscle.
Sheatfish
Definition:
(n.) A European siluroid fish (Silurus glanis) allied to the cat-fishes. It is the largest fresh-water fish of Europe, sometimes becoming six feet or more in length. See Siluroid.
Example Sentences:
(1) 100% of sheatfish fry infected by water bath died within 8 days.
(2) The sheatfish, Silurus glanis (L.), from the terminal part of River Po was examined for the presence of helminth parasites.
(3) In case of common secretory specialization, it can be a) isomorphous--at identical convertion of the epithelium in the whole follicle (for example, in sheatfish), b) dimorphous--when there is a certain difference in the character and degree of secretory specialization of the follicular epithelium in various follicular areas (for example in Myxine glutinosa); 2) unipolar secondary transformation when the follicular epithelium undergoes secondary flattening or secretory specialization only in the area adjacent to one of the oocyte poles (for example, in Lametra fluviatilis and Blennis follis).
(4) An iridovirus-like agent which was isolated from sheatfish fry showed to be of high virulence to those fish.
(5) In 45 sheatfish of total length < or = 40 cm, specimens of P. laevis were found encapsulated in mesenteric and peritoneal tissues.

(7) The greatest degree of localization of the degenerated terminals was revealed in the dorsolateral area of the medial nucleus on the ipsilateral side, where previously, under adequate stimulation of the organs on the lateral line of the dwarf sheatfish, the greatest amount of responses was registered.
(8) A radioimmunoassay was to determine the content of estrogens, progestins and androgens in the blood plasma of female and male big-mouthed buffalo, silver carp and canal sheatfish before reproduction and in the first two species during reproduction as well.
