Without few exceptions, organic farming in Bangladesh is still on experimental basis. Based on International Federation of Organic Agricultural Movement (IFOAM) statistics, total land area under organic cultivation in Bangladesh is 0.177 million ha that is only 2 percent of the country’s total cultivable land and till the decade only 100 of its traditional farms have been converted into organic. Actually, organic farming has been introduced in the country particularly by the NGOs. Since the inception of organic farming in the country, still this movement is running with the direct leadership of different NGOs. According to IFOAM (1996), “138 NGOs are the member of the Forum for Regenerative Agriculture Movement (FORAM), 47 of them are engaged in practicing organic agriculture, 87 are intending to practice sustainable agriculture and 3 of them are engaged in advocacy, lobbying and campaign for sustainable development in Bangladesh”.
Diseases of Pangasius and catfish deteriorate production and benefit. Diseases of Pangasius and catfish are main obstacle of culture. Pangasius culture has become main fish culture in Bangladesh mainly northern part. Diseases of pangasius and catfish caused by viruses, bacteria, fungi, parasites, and other pathogens. The cost of disease prevention and treatment is 5 to 5.5% of total production cost (Dung et al., 2008; Hung and Huy, 2005; Khoi et al., 2008). Farmer use
antibiotic for treatment of fish diseases.
The results of the multiple-case study show that most farmers do not know exactly what kind of antibiotics they should use during disease outbreak (Khoi et al., 2008). Small farmer know about fish diseases from friend and different drug dealer. In many cases, local veterinary drug suppliers have no knowledge in either aquatic organisms or veterinary drugs (Khoi et al., 2008). Continue reading Diseases of Pangasius and catfish→

Pangasius hypophthalmus prolific spawner produce relatively large numbers of larvae that are easily harvested from the river and pond of Viet Nam, Thailand, Cambodia and Bangladesh also.

Isolation and Characterization of Pathogenic Bacteria from Diseased Silkworm (Bombyx mori L.) and Antibacterial Activities of Different Plant Extracts
About 34 to 40 percent of total crop in a year has been reported to be loss due to diseases because of the occurrence of four major diseases namely pebrine (Protozoan disease), flacherie (bacterial disease), grasserie (Viral disease) and muscardine (Fungal disease). Flacherie is known to be caused the assembly of various pathogenic bacteria in silkworms and are commonly known as bacterial flacherie.
