Abstracts: Stocking density limits for post-smolt Atlantic salmon (Salmo salar L) with emphasis on production performance and welfare

For the development of commercial scale semi-closed sea systems for farming post-smolt Atlantic salmon (Salmo salar), further knowledge is required on the interaction between fish density, farming conditions and fish welfare. Continue reading Abstracts: Stocking density limits for post-smolt Atlantic salmon (Salmo salar L) with emphasis on production performance and welfare

Abstracts: Searching for Lyme borreliosis in Australia: results of a canine sentinel study

BACKGROUND: Lyme borreliosis is a common tick-borne disease of the northern hemisphere that is caused by bacterial spirochaetes of the Borrelia burgdorferi (sensu lato) (Bbsl) complex. To date, there has been no convincing evidence for locally-acquired Lyme borreliosis on the Australian continent and there is currently a national debate concerning the nature and distributions of zoonotic tick-transmitted . . . → Read More: Abstracts: Searching for Lyme borreliosis in Australia: results of a canine sentinel study

Reduced heart rate variability in pet dogs affected by anxiety-related behaviour problems

We present here the first evidence of correlation between canine anxiety-related behavioural problems and heart rate variability (HRV). HRV is known to be related to a range of mental disorders in humans; however this has not been explored in dogs. Behavioural problems in dogs can result in suffering, property destruction and human injury. Dog behaviour problems . . . → Read More: Reduced heart rate variability in pet dogs affected by anxiety-related behaviour problems

What we know about the public’s level of concern for farm animal welfare in food production in developed countries

Population growth and rising consumption of meat, dairy, eggs and fish are forcing the world to face the intersecting challenges of how to sustainably feed a population expected to exceed 9 billion by 2050, while also controlling the impact of food production on the planet, on people and on animals. This review acknowledges the absence of . . . → Read More: What we know about the public’s level of concern for farm animal welfare in food production in developed countries

Seals assisting science

Picture: Chris Oosthuizen

Elephant seals have again been key to the ability of researchers to establish the source of an important secondary contribution to East Antarctica’s Cape Darnley bottom water. Antarctic bottom water is formed when cold, salty and dense water sinks and flows away from the continent in enormous volumes. It is considered an important . . . → Read More: Seals assisting science
