The shrimp aquaculture industry ranks as the highest foreign exchange earner among the marine product exports from India. Countries like India, Ecuador, Vietnam and Indonesia have emerged as global leaders in shrimp production. In spite of being the most rapidly expanding sector in food production, aquaculture is vulnerable to losses caused by disease. Current growth in aquaculture production is parallel with the increasing number of disease outbreaks, which can affect the production, profitability and sustainability of the industry worldwide. Among the groups of pathogenic microorganisms, Vibrios are well-known causatives of massive mortalities in farmed shrimp, fish and shellfish resulting in severe economic losses. An intensive mode of culture with high stocking densities have resulted in an increase in the incidence of diseases. To maintain productivity in such intensive aquaculture production systems, massive use of antibiotics had been employed. The spread of antibiotic resistance from aquaculture settings to the natural environment is increasing. About 70% of the Vibrios isolated from aquaculture settings are multi-drug resistant. Bacterial infections, including multi drug- resistant strains, have been recognized as an important limitation to the development of the aquaculture production.... .................

Many developing countries recognize ornamental fisheries as economically important for employment generation and livelihood development. In ornamental fish trade India’s share is estimated to be around Rs.158 lakhs which is only 0.008% of the world trade. Indigenous wild catch ornamental fishes contribute maximum towards the major export of ornamental fishes. In India, North-eastern states and West Bengal are having a rich freshwater fish biodiversity resource of about 300 fish species belonging to 10 orders, 37 families and 114 genera that have high ornamental value. Among these indigenous ornamental fish, fresh water eel has enormous opportunity not only in the Indian ornamental fish market but also globally. Eels are now widely used in aquarium fish keeping and presently these are also exported like other indigenous ornamental fish species. As the Eel species are compatible with other species and hardy for aquaria, their importance is growing by the day. The fish is not yet fully incorporated in inland culture system. The main reasons behind this are insufficient information on the captive induced breeding, inadequateness of natural fry and absence of commercial hatchery production. The brief data on morphology, feeding biology, habitat and reproductive biology of Macrognathus species are reviewed in this study....…....... Read to know more…...

Preferred by aquarists for its sturdy appearance and hardiness, Anabas is a belligerent yet shy fish that looks very attractive in an aquarium. Highly variable in body form and meristics, these are generally not very suitable for a community aquarium. Anabas species, belonging to the family Anabantidae, are air-breathing fishes generally known as “climbing perch”. They are generally found in India, Sri Lanka and Southeast Asia including China. Though they are occasionally seen in brackish water, Anabas mainly inhabit small, densely grown streams, rice fields and muddy pools. With a slender body covered with large scales and spines on the gill cover, the climbing perch is grayish brown to pinkish silver in colour. More colours have been noticed as they grow. A dark spot on the base of the caudal fin and a reddish hue on the fins are also observed.. Read on to know more …... . To read full article Subscribe too
