Global molluscan aquaculture production is continuously increasing, dominated by five species, among which the Pacific cupped oyster, Crassostrea gigas, predominates. Hatchery production is accompanying this increase to assist consistent availability of juveniles for restocking, fishery enhancement, genetic improvements as well as for species diversification. Hatchery development contributes si...

Vaccination has an important role in the prevention of ND even though an ideal vaccination program can not be easily given as it would depend on level of challenge in the field, disease control polices in the country, type of birds (broilers or layers), vaccine strain, size of the flock, past performance of vaccination programs etc. However, the vaccination in the hatcheries has been used throu...

Veterinary control and routine sanitary procedures in commercial poultry hatcheries should include the following: choice of a suitable geographical location to ensure an isolated site; proper hatchery design with separation of major operations; one-way flow of work within the hatchery; adequate ventilation of each room; routine cleaning and disinfection; formaldehyde fumigation or alternative m...

Early-rearing salmonids in Ontario Ministry of Natural Resources (OMNR) fish hatcheries have been consistently affected by bacterial gill disease (BGD) (causative agent: Flavobacterium branchiophilum) for many years. Separate retrospective epidemiological investigations of BGD treatments at two OMNR fish hatcheries (Hatcheries A and B) for the 1999 production year were conducted using on-site h...

Vibrio bivalvicidais a novel pathogen of bivalve larvae responsible for recent vibriosis outbreaks affecting shellfish hatcheries. Here, we announce the draft genome sequence ofV. bivalvicida605(T)and describe potential virulence factors.

Residents of the Red River Delta region of northern Vietnam have a long tradition of eating raw fish. Fish-borne zoonotic trematodes (FZTs) are estimated to infect ≈1 million persons in Vietnam. It remains uncertain at what stages in the aquaculture production cycle fish become infected with FZTs. Newly hatched fish (fry) from 8 hatcheries and juveniles from 27 nurseries were therefore examined...

The present work was carried out to isolate and identify fungi species present in dead-in-shell chick embryo. A total of three thousand dead-in-shell embryonated chicken eggs pooled into 300 eggs (10 eggs per group) were collected from the four hatcheries over a period of six months. The contents of the pooled eggs were inoculated onto Sabourauds Dextrose Agar (SDA) and Corn Meal Agar (CMA) sla...

Fungal infections cause significant economic losses in the poultry industry either due to their direct infectious nature or due to mycotoxins production. Hatchery contamination with fungi can threaten chicken health. In this regard, geographical and seasonal distributions of airborne fungal contamination of 25 hatcheries in Mazandaran province, northern Iran, were investigated using an open pla...
