Diseases of Pangasius and catfish

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

Role of Women and their Socio-Economic Status in Shrimp Farming

Role of Women and their Socio-Economic Status in Shrimp Farming are very important and vast to describe. Shrimp culture has changed the livelihood pattern of the coastal region people of Bangladesh.

Since 1980, fry collection has become the chief source of livelihood for women and children in coastal area. Surviving the livelihood near about 83.08 percent population, both males and females were engaged in shrimp fry collection in all around the year. (Halim et al, 2001).

Exportable Pangasius Hypophthalmus for best fillets

Fillets producing fish (Pangasius hypophthalmus Sauvage, 1878 )
Habit and Habitat: Pangasius hypophthalmus is fresh water fish species. Mekong River fishery occupied most of that major fish species, Pangasius hypophthalmus is the largest and most important inland fisheries in the world. 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. P. hypophthalmus is a highly migratory riverine fish species that makes long-distance migrations.

Pathogenic Bacteria from Diseased Silkworm (Bombyx mori L.)

 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.

Can Diatomaceous Earth Change Life-History Traits in Musca domestica L.

Diatomaceous Earth-Induced Changes in the Life-History Traits in Musca domestica L. (Diptera: Muscidae)

ABSTRACT

The present investigation was split into the following five experiments:

Experiment One: Using doses of 0.0, 0.2, 0.4, 0.6 and 0.8 mg/l00ml diatomaceous earth (DE) in the larval food medium, a mean LC50 of 0.66mg/l00ml was determined for the 31instar larvae of M domestica. Experiment Two: Here the time-course mortalities of the 3rd-instar larvae were evaluated, wh
