Impact of de-silting of pond on the growth and survival of catla (Catla catla) spawn.

Experiments were conducted in non-desilted and de-silted earthen nursery ponds for a period of fifteen days to evaluate the growth and survival of Catla spawn. The fry attained an average weight of 42.03 +/- 0.36 and 74.36 +/- 72 mg, with a survival rate of 23.44 +/- 0. 31 and 50.91 +/- 0.21% in non-desilted and de-silted ponds respectively Mentioned length data also indicate that growth and su...

Susceptibility and pathological consequences of catla, Catla catla (Hamilton) experimentally infected with Edwardsiella tarda

The present study tested the susceptibility and pathological changes of catla, Catla catla (Hamilton) infected with Edwardsiella tarda (ET-PG-29). The bacterium was isolated from the kidney of a diseased pangas catfish. To determine the median lethal dose (LD50), C. catla were challenged with this bacterium (10-10 CFU ml), and the LD50 was calculated as 10 5.5 CFU ml. Another set of healthy C. ...

Histopathological Effects of Bisphenol-a on Liver, Kidneys and Gills of Indian Major Carp, Catla Catla (hamilton, 1822)

Bisphenol-A (BPA) is a xenoestrogen that mimics the action of natural estrogen, estradiol-17β, and can disrupt the endocrine system. Present study was designed to investigate histopathological effects of BPA on some vital organs of major carp, Catla catla. Fish were exposed to various sub-lethal concentrations (1 to 4 ppm) of BPA in a semi-static system for 15 days. After the stipulated time, l...

Prevalence and effects of Lernaea cyprinacea (anchor worm) on the growth, skin histopathology and hematology of Catla catla

The experiment was conducted to evaluate the prevalence of Lernaea cyprinacea and its effects on growth, hematology and skin histopathology of Catla catla in four experimental earthen ponds (P1, P2, P3 and P4) for 90 days. The growth performance, prevalence of Lernaea cyprinacea and ulceration was recorded on a fortnightly basis. The highest final body weight was observed in P4 (413.7 g) follow...

Identification and characterization of chickenII - GnRH ( cII - GnRH ) gene of Catla catla ( Hamilton , 1822 )

Gonadotropin-releasing hormone (GnRH) is a neuropeptide hormone responsible for the release of luteinizing hormone (Lh) and follicle-stimulating hormone (Fsh) from the anterior pituitary gland . GnRH have been identified and characterized from the brain of C. catla. A cDNA fragment of 202bp was amplified and GnRH variant has been identified in the form chicken-II-type gonadotropin-releasing hor...
