Olfactory Sensory Neuron Morphotypes in the Featherback Fish, Notopterus notopterus (Osteoglossiformes: Notopteridae)
BACKGROUND As in other vertebrates, olfactory sensory neurons (OSNs) in fishes are the main components of sensory part of olfactory epithelium that relay olfactory information (smell and taste) to the brain. PURPOSE Objective of the present study was to analyze if any polymorphism occurs in the OSNs in a featherback fish, Notopterus notopterus as far as the teleost lineage is concerned. MET...
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 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 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...
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...
