Data for a total of approximately 1100 lambs tested in 12 trials from 1992 to 1995 in commercial lamb test stations in Quebec were used to determine the effect of sex, sire breed and genetic type on growth performance and carcass characteristics. Lambs were housed two to a pen and fed commercial die...

Data from approximately 850 commercial pigs tested in 12 trials, from 1987 to 1990 at the Beaumont test station in Quebec were used to determine the effect of growth rate and body composition on growth performance, carcass yield and lean meat colour. Pigs were housed four to a pen and were fed comme...

Infectious hematopoietic necrosis virus (IHNV) has been found to cause disease in cultured salmon of the Pacific Northwest region of North America. Diagnosis of IHNV by virus isolation (VI) can take over 2 weeks. Recently, a rapid reverse transcriptase (RT) polymerase chain reaction (PCR) test on fi...

The depletion of emamectin B1a in the edible tissues of Atlantic salmon (Salmo salar) was studied at two inclusion rates of emamectin benzoate (EMB; Slice®) in commercially prepared diets. Fish were maintained in tanks supplied by flow-through, temperature-controlled natural seawater at 10.08±0.26...

Data from a total of approximately 2900 commercial pigs tested in 12 trials from 1987 to 1990 at the Beaumont test station in Quebec were used to determine the effect of sex, sire breed, cross type and parity number of the dam on meat colour. Pigs were housed four to a pen and fed commercial diets. ...

Pigs were housed four t...

Mortality levels attributed to infectious salmon anaemia viral (ISAV) infections were examined at the net pen and site level in the 1996 smolt year class in three areas of New Brunswick, Canada. The year class in this region was the first known to have potential exposure to ISAV beginning at the tim...

Growth indices were examined in 24 identically managed tanks, each containing 120 diploid juvenile rainbow trout (initial mean body weight, 9.3 g) during a 12-week study to examine tank effects associated with tank location in a multi user research facility. Growth indices included mean body weight,...

Outbreaks of unexplained mortalities attributed to infectious salmon anaemia (ISA) were examined in the 1996 year class of Atlantic salmon in three regions of New Brunswick, Canada. A total of 218 net pens at 14 sites deemed to have been exposed to ISA virus (ISAV) were surveyed for mortality record...

Reference ranges for blood chemical and cellular components in the "healthy" population of interest are required to identify alterations in individuals in association with disease and disorders. The purpose of this study was to determine reference ranges for various constituents of hemolym...

Over the last 10 years, there have been sporadic increases in early sexual maturation (grilsing) in Atlantic salmon (AS) in seawater grow-out sites in New Brunswick with an apparent upward trend. Grilsing in AS reduces flesh quality and growth. With estimated gross revenue of $250 million in 2002, l...

The first known case of mortality due to infectious salmon anaemia (ISA) virus in Canada occurred in New Brunswick in the late summer of 1996. In an observational study of risk factors associated with ISA virus (ISAV) outbreaks, mortality patterns were used to define cases at the cage level and the ...

Proper monitoring of all stages of sea lice is imperative to ensure the strategic timing of treatments. Although sea lice receive close attention and management for production purposes, there are no regulations for the reporting of lice burdens on salmon farms in Atlantic Canada, nor are there offic...

Reverse transcriptase polymerase chain reaction (RT-PCR), virus isolation (VI) and indirect fluorescent antibody tests (IFAT) are three assays currently used by the salmon industry to identify fish infected with infectious salmon anaemia virus (ISAV). However, no data are available on the repeatabil...

Infectious salmon anaemia (ISA) is an economically important disease in New Brunswick, Canada. Current regulatory control involves detection of ISAv in broodstock, hatcheries and marine sites through a surveillance program. Prior to recent assessments of operating characteristics of diagnostic tests...

Reverse transcriptase-polymerase chain reaction (RT-PCR), virus isolation (VI) and indirect fluorescent antibody test (IFAT) are three tests currently used by the salmon industry to identify fish infected with the infectious salmon anaemia virus (ISAV). However, very limited information is available...
