The dietary iron requirement for normal growth and optimum hematological values and bioavailability was determined for channel catfish Ictalurus punctatus fingerlings using eggwhite based diets supplemented with 0,5,10,20,60, and 180-mg ironkg from iron methionine or 20, 60, and 180-mg ironkg from iron sulfate. The basal diet which contained 9.2-mg ironkg, 34% crude protein and 3.1 kcal of dige...

Probiotics are gaining popularity both empirically and scientifically as eco-friendly alternatives in aquaculture. The present research proposed to examine the influences of selective probiotics on growth, hematology, microbes, morphology intestine stinging catfish (Heteropneustes fossilis) a biofloc system. Additionally, this study evaluated benefit–cost ratio (BCR) specific used Stinging fing...

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...

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...

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...

Thelohanellus infection of the scales of the European wild carp Cyprinus carp10 carplo L 1s reported for the first time in Europe Comparative morphological and histological f i nd~ngs are descnbed Plasmodia and spores found In the fins of cultured common carp fingerlings and those detected in the scales of 2to >4-yr-old European wild carp belong to the same species The morphological chardcteris...

Static bioassays were performed to observe the toxic effect of malathion to Barbodes gonionotus at 0.0 to 20.0 ppm concentrations. Malathion at 5.0 ppm was harmless to B. gonionotus and concentration above 6.0 ppm were found to be lethal. Malathion at 2.06 ppm was safe for the B. gonionotus.
