Cage‐pond integration system is a new model for enhancing productivity of pond aquaculture system. A field trial was conducted using African catfish (Clarias gariepinus) and Nile tilapia (Oreochromis niloticus) in cages and carps in earthen ponds. There were four treatments replicated five times: (1) carps in ponds without cage, (2) tilapia at 30 fish m^?3 in cage and carps in open pond, (3) catfish at 100 fish m^?3 in cage and carps in open pond, (4) tilapia and catfish at 30 and 100 fish m^?3, respectively, in separate cages and carps in open pond. The carps were stocked at 1 fish m^?2. The cage occupied about 3% of the pond area. The caged tilapia and catfish were fed and the control ponds were fertilized. Results showed that the combined extrapolated net yield was significantly higher (P < 0.05) in the catfish, tilapia and carps integration system (9.4 ± 1.6 t ha^?1 year^?1) than in the carp polyculture (3.3 ± 0.7 t ha^?1 year^?1). The net return from the tilapia and carps (6860 US$ ha^?1 year^?1) and catfish, tilapia and carps integration systems (6668 US$ ha^?1 year^?1) was significantly higher than in the carp polyculture (1709 US$ ha^?1 year^?1) (P < 0.05). This experiment demonstrated that the cage‐pond integration of African catfish and Nile tilapia with carps is the best technology to increase production; whereas integration of tilapia and carp for profitability.  相似文献

Hematological and pathological effects of chromium toxicosis in the freshwater fish,Barbus conchonius Ham     

Tejendra S. Gill  Jagdish C. Pant 《Water, air, and soil pollution》1987,35(3-4):241-250

Experimental exposure to Cr(VI) induced anomalies in the peripheral blood and tissues of a freshwater fish, Barbus conchonius. Clinical findings in the blood corpuscles included swelling of erythrocytes, numerous circulating polychromatophils, and vacuolation of large lymphocytes during acute exposure. Poikilocytosis, severe cytoplasmic vacuolation and deterioration of cytoplasmic membrane in erythrocytes occurred following chronic exposure. Significant polycythemia with collateral rise in Hb and Hct were manifest in the acutely intoxicated fish. By contrast, chronic exposure caused marked erythropenia and an accompanying reduction in Hb and Hct values. Leucocyte subpopulations showed an initial rise and then a fall in the thrombocytes together with a significant lymphocytosis, neutropenia, and basophilia. Pathological changes were observed in the gills, kidneys, and liver of Cr-exposed fish.  相似文献   

Development of non-narcotic (opiumless and alkaloid-free) opium poppy, Papaver somniferum     

J. R. Sharma    R. K. Lal    A. P. Gupta    H. O. Misra    V. Pant    N. K. Singh  V. Pandey 《Plant Breeding》1999,118(5):449-452

A mutation breeding programme using gamma rays and ethyl methane sulphonate (EMS) was carried out for genetic conversion of narcotic ‘opium poppy’ into non-narcotic ‘seed poppy’. Two families contained 31 latexless (opiumless) and 23 partial latex-bearing plants which were identified in the M² and confirmed in the M³ generations by the ‘ray-pluck’ method. Thin-layer chromatography (TLC)-densitometry of powdered capsule hulls (straw) from 22 representative plants also revealed that none of the five opium alkaloids (morphine, codeine, thebaine, papaverine and narcotine) was present in the straw. Six plants also possessed high seed yield (4.0–5.66 g/capsule vs. 3.39 g for control) and seven had a high seed oil content (50.7-53.5%). The best mutant genotype, LL-34 of the family C¹-Comb-113-2, with 5.66 g/capsule seeds containing 52.6% oil was designated as cv. ‘Sujata’. This, perhaps the world's first opiumless and alkaloid-free seed poppy cultivar, offers a cheap and permanent (fundamental) solution to the global problem of opium-linked social abuse. Simultaneously, it serves as a safe and potential food crop with protein-rich seeds and healthy unsaturated seed oil.  相似文献

Mercury-induced blood anomalies in the freshwater teleost     

Tejendra S. Gill  Jagdish C. Pant 《Water, air, and soil pollution》1985,24(2):165-171

Experimental Hg poisoning in the fish, Barbus conchonius led to marked hematological anomalies. Acute exposure to 181 μg L^?1 mercuric chloride (96 h LC50) led to erythrocytic anomalies including vacuolation, nuclear deterioration, microcytosis and collapsed cytoplasmic membranes. In addition, there was significant thrombocytosis and neutropenia together with a slight reduction in lymphocyte count. Chronic exposure to 36 and 60 μg L^?1 mercuric chloride led to poikilocytosis, hypochromia, fragmentation and nuclear displacement in erythrocytes. The large lymphocytes revealed vacuolation, cellular and nuclear hypertrophy and cytoplasmic outgrowths. Thrombocytosis, lymphocytosis, neutropenia and mild basophilia were manifested in fish subjected to chronic poisoning.  相似文献   

Study on the liquid flow behaviour of cotton wick     

A. Das  A. Jain  A. Pant 《Fibers and Polymers》2008,9(2):176-186

The present paper reports the interaction effect of yarn twist, yarn count and number of plies on wicking behaviour of plied cotton yarn. A three-variable factorial design technique proposed by Box & Behnken was used to investigate the combined interaction effect of the above variables. Both the vertical as well as horizontal wicking experiments were carried out with liquids of varying surface tensions, like distilled water, saline water and petrol. Each wick samples were subjected to nine different types of wicking related tests. The yarn count and number of plies in the cotton wick was found to play major role in wicking related properties, whereas the effect of twist in plied cotton wick was not that prominent when the twist per unit length of single and plied yarns were the same and in opposite direction. The rate of vertical wicking for saline water was found to be significantly lower than that of distilled water. The rate of horizontal wicking for distilled water was less than that of vertical wicking of distilled water. Use two or three parallel strands instead of one resulted in marked increase of vertical wicking.  相似文献   

Inducement of metabolic dysfunction by carbamate and organophosphorus compounds in a fish, Puntius conchonius     

Jagdish C. Pant  Tejendra Singh 《Pesticide biochemistry and physiology》1983,20(3):294-298

Exposure of a freshwater cyprinid (Puntius conchonius) to 2.142 and 4.784 ppm of carbaryl and dimethoate, respectively, for 24 hr, seriously affected carbohydrate and cholesterol metabolism. Significant hyperglycemia and glycogenolysis in liver, brain, and heart were manifested in the treated fish. Hypercholesterolemia and rise in liver cholesterol also occurred. Long-term exposure, 15–30 days, to chronically sublethal concentrations, 0.194 and 0.306 ppm carbaryl and 0.434 and 0.683 ppm dimethoate, elicited hypoglycemia and depletion of liver glycogen, together with enhanced glycogenesis in the heart. The glycogen level in brain fell in response to carbaryl exposure in contrast to a significant elevation caused by dimethoate. Reduction in blood and liver cholesterol at 15 days was followed by an increase at 30 days.  相似文献
