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...

The decline in dental caries in children in North America, Scandinavia, Britain, Ireland and many Commonwealth nations is well documented. The multiple uses of fluoride can account for most, but not all, of this reduction. In this investigation, data are provided which suggest a relationship between antibiotic usage for medical purposes and a decline in both mutans streptococci (MS) and caries....

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. ...
