Present study was conducted in fish hatcheries, nurseries and culture farms to find out different chemicals used in freshwater aquaculture activities in Noakhali District, Bangladesh. Data were collected through questionnaire interview, personal contact, market survey and participatory rural appraisal (PRA) like focus group discussion (FGD) with fish hatchery owners, nursery and culture farmers...

The sensitivity of an enrichment culture procedure for detecting Clostridium botulinum type E in whitefish chubs (Leucichthys sp.) was assayed. Data demonstrated that fish inoculated with 10 or more viable C. botulinum spores regularly develop specifically neutralizable enrichment cultures. Mild heat treatment (60 C, 15 min) substantially reduced the sensitivity of enrichment culturing. This ef...

Introduction The question of bacterial culture sensitivity for individual versus pooled samples was discussed at the 2001 Fish Health Biologist Meeting in Tucson, AZ, as procedures for the USFWS Handbook were being developed. The USFWS Handbook strives to conform with methods specified by the Office International des Epizooties (OIE 2000) and the American Fisheries Society (AFS) Blue Book (Thoe...

The demand for and costs of producing land-based animal protein continues to escalate as the world population increases. Fish is an excellent protein, but the catch-fishery is stagnant or in decline. Intensive cage culture of fish is a viable option especially in countries with lakes/rivers and/or a long coastline; however, disease outbreaks will likely occur more frequently with cage culture. ...

Members of the genus Vesiculovirus, which belongs to the family Rhabdoviridae, can cause great economic loss in fish culture. In the present report, a vesiculovirus [named snakehead fish vesiculovirus (SHVV)] was isolated from diseased hybrid snakehead fish. SHVV shared 94 % nucleotide sequence identity at the genomic level with Siniperca chuatsi rhabdovirus (SCRV), which infects mandarin fish ...
