As new pathogenic strains are emerging and threatening aquaculture development, myxosporeans (Myxozoa) are receiving much attention in recent years. Myxosporean taxonomy is traditionally based on morphology of the myxospore stage. Molecular data on Indian myxosporeans are rare. In this report, the 18S rRNA gene sequence of Myxobolus cuttacki infecting gill lamellae of minor carp Labeo bata (Ham...

The use of probiotic bacteria can not only enhance the nutritional utilization fish feeds to produce more biomass but also provide a practically “safer” alternative farming industry reduce abuse antibiotics and drugs. This study investigated possibility colonizing Lactobacillus rhamnosus strain GG (LGG) intestine Cirrhinus molitorella (mud carp) fingerling. Colonization LGG was observed in gut ...

Background: Test of pahogenecity of fish pathogens usually done by injection or ingestion of the bacterial samples on the fish. Objective of the current research was to introduce a new method of testing pathogenecity of fish pathogens through an artificial infection system. The targeted method was to observe the pathogenecity in aquarium condition by direct infection of the system water with ba...

The morphoanatomy, cellular organization, and surface architecture of the olfactory apparatus in Cirrhinus reba (Hamilton) is described using light and scanning electron microscopy. The oval shaped olfactory rosette contained 32 ± 2 primary lamellae on each side of the median raphe, and was lodged on the floor of the olfactory chamber. The olfactory lamellae were basically flat and compactly ar...

In the present study, fresh waterfish Cirrhinus mrigala has been used as a model organism to understand mechanistic link between electroplating industrial effluent (EIE) and oxidative stress in aquatic ecosystems. To this end, fishes were exposed effluent, tank water for 10, 20 30 days under controlled laboratory conditions. Various hematological parameters (Total RBC WBC, Hemoglobin, MCV, MCH,...

In general, any stress inducing substance will affect the respiratory metabolism of an animal. Any alteration in the intermediary metabolism due to stress is bound to affect the activity of oxidative enzymes like lactic dehydrogenase (LDH) and succinic dehydrogenase (SDH). Both enzymes are involved in carbohydrate metabolism and have been used as an indicative criterion of exposure to chemical ...

Zidovudine (AZT) induced concentration related aggregation in C. mrigala melanophores. Denervated melanophores failed to respond to AZT. Specific and nonspecific alpha adrenoceptor antagonists completely blocked the responses of fish melanophores to AZT. Histamine and prostaglandin antagonists also inhibited aggregation of the melanophores induced by AZT. The results suggest that AZT may releas...
