Two New Species of the Genus Pallisentis Van Cleave, 1928 (Acanthocephala: Quadrigyridae) from the Intestine of Channa punctatus (Bloch, 1793) from the River Gomti at Lucknow, India
BACKGROUND Acanthocephalans are fish parasites of worldwide distribution, penetrate their thorny proboscis into the intestinal wall of host and absorb nutrients. No diagnostic tool is available except postmortem investigations and identification by parasitologists. The aim of present study was to explore and assign taxonomical status to Pallisentis species prevalent in food fishes of river Gomt...

متن کاملEffect of different protein levels on reproductive performance of snakehead murrel Channa striatus (Bloch 1793)
In this study the effect of different protein levels on reproductive performance of Channa striatus was conducted. Snakehead juveniles (65.5±0.2 g) were randomly distributed into nine homogenous groups of 75 fish each. Three isocaloric experimental diets differing in protein levels were prepared. The experiment lasted for 8 months and gonadosomatic index, absolute fecundity, egg diameter, numbe...
متن کاملPurification of vitellogenin from the plasma of Indian freshwater murrel, Channa punctatus (Bloch) by different methods: a comparative study.
Plasma from estrogenized, [32P] NaH2PO4-injected murrel, Channa punctatus was collected in the presence of proteolytic inhibitors and subjected to different separation procedures singly or in combination, viz., gel filtration chromatography on Ultrogel AcA 34, ion-exchange chromatography on DEAE sephacel, or selective precipitation with dimethylformamide or with Mg2+: EDTA in order to isolate v...
متن کاملImmunological identification of two female-specific proteins from the plasma of Indian freshwater murrel, Channa punctatus (Bloch).
Existence of a non-phosphorylated female-specific protein (FS II), in addition to phosphorylated vitellogenin (FS I), in the plasma of murrel by exogenous administration of estradiol-17beta is reported. Polyspecific rabbit antibodies were raised against estrogen-inducible murrel plasma proteins. This antiserum was absorbed with normal male serum in order to obtain female-specific antiserum (FSA...
