Comparative studies on blood electrolytes of the fresh water fish, Notopterus notopterus from three aquatic bodies
The present study is undertaken to determine baseline levels of blood electrolytes for the fish, N.notopterus collected from three different aquatic bodies situated at different locations around Gulbarga region. The electrolytes such as sodium and potassium levels are having some difference in the fish collected from the three aquatic bodies. The data for blood Sodium 88.49 ± 16.68 mmol/l. in t...
متن کاملEffect of cortisol on testis of freshwater fish Notopterus notopterus (Pallas).
Cortisol (20, 40 and 60 micrograms/fish for 10 days) treatment caused an increase in testicular-somatic index (TSI) in immature N. notopterus whereas in mature fish no change from that of controls was observed. Histology of testis indicated that spermatogenetic activity was activated in immature fish while it was inhibited in mature fish. Testicular cholesterol exhibited a similar response. The...
متن کاملHaematological Changes Induced by Short - Term Exposure to Copper in the Indian Freshwater Fish, Notopterus Notopterus (pallas)
The health of fish can be affected by environmental factors (stress), nutrition as well as by pathogens. Stress in fish may be induced by various abiotic environmental factors such as changes in water temperature, pH, oxygen concentration and water pollutants including pesticides, insecticides (Meier et al., 1983; Lebelo et al., 2001), petroleum products and heavy metals (Witeska, 1999). Biotic...
متن کاملEffect of cortisol on female freshwater fish Notopterus notopterus.
In the present study, effect of cortisol on the ovary of the freshwater fish Notopterus notopterus was studied during four phases of the reproductive cycle. The hormone was injected 60microg/fish for ten days. Cortisol in fish is known to increase the metabolic activity. After the hormone treatment the ovarian somatic index and the hepatosomatic index increases during non breeding phase. The yo...
متن کاملTissue cholesterol and serum cortisol level during different reproductive phases of the female freshwater fish Notopterus notopterus (Pallas).
In the present study tissue cholesterol and serum cortisol changes during two reproductive phases have been correlated in the freshwater fish Notopterus notopterus. The reproductive cycle of N. notopterus has two phases such as breeding phase (April - August) and non breading phase (October - December). The cholesterol content of the ovary and liver increased during breeding phase. The serum co...
