Atrazine (2-chloro-4-ethylamino-6-isopropylamino 1,3,5-triazine) is a widely used selective herbicide. Due to its persistence, it is present in the surface waters, contaminating non-target organisms such as fish. Herbicide atrazine was administered to Labeo rohita fingerlings in 120 hours. The used dose of atrazine was 0.18 mg/l for 120 hours (LC ). The histopathological changes in the gill tis...
The experimental studies on uptake and accumulation of 106Ru by artificially fertilized eggs, advanced fry and fingerlings of rainbow trout have been conducted. The accumulation in the egg previously treated with drugs for control of bacterial growth on the egg was more rapid and higher than that in non-treated egg. The major part of 106Ru in the egg was associated with the egg capsule on hatch...
Background: Edifenphos, a kind of organophosphate toxins, is used as agricultural fungicides in rice fields. This study was aimed to investigate the effect of temperature on lethal concentration of exposure to edifenphos on Rutilus frisii kutum (Caspian kutum). Methods: The experiment was carried out in static condition and based on instructions of OECD within 10 d under controlled water phy...
To study the effects of post-stripping oocyte ageing at low temperatures on the viability of kutum (Rutilus kutum) oocytes, unfertilised eggs of five females were stored in ovarian fluid at temperatures of 4 and 7 degree centigrade for 24 hours post stripping (HPS). The stored ova of five female kutum were separately fertilised at 0 (i.e., control eggs fertilised prior to storage), 4, 8, 12, 16...
The Caspian kutum, Rutilus kutum Kamenskii, 1901 from Cyprinidae family is native in the Caspian Sea, with the highest distribution in the southern part and rarely seen in the northern and is an economically important species along the Caspian Sea. Despite this, knowledge about stock structure is scarce and there is no formal management strategy to ensure the long-term sustainability of this va...
Community Level Physiological Profiles (CLPP) is novel method to evaluate microbial activity and diversity in ecosystems. According to the previous findings, poly-β-hydroxybutyrate (PHB) as a bio-control product, increases bacterial diversity in some aquatic animals. In this study, the effects of four experimental diets (control, combination of two PHB degrading bacteria, 2% PHB, bacteria+ 2% P...
A study was carried out to evaluate the probiotic activity of Bacillus subtilis G1 isolated from fermented pickles in growth performance and disease resistance of Hemibagrus nemurus fingerlings at Universiti Putra Malaysia. The probiotic was mixed in feed at doses of 0 (C, control), 3 x 109 (T1) 3 x 107 (T2) and 3 x 105 (T3) cfu g-1 and fed to the catfish fingerlings for nine weeks. Results sho...
This current study was planned to evaluate effect of exogenous phytase supplementedMoringaoleifera leaf meal (MOLM) diet on mineral digestibility of Oreochromis niloticus fingerlings. To conduct the experiment, six experimental diets based on MOLM with 0, 200, 400, 600, 800 and 1000 FTU kg-1 phytase level wereformulated. Chromic oxide (1%) was added in the feed as indigestible marker. Completel...
Infectious pancreatic necrosis (IPN) is a viral infection primarily of trout and salmon, but the virus has also been isolated from a wide variety of other fish species. The infection is characteristically seen in trout as an acute disease causing high mortality in fry and fingerlings. However, it may also occur as a benign and inconspicuous infection (Bullock et al. 1976). Because high fish los...
