The heart and circulatory system

That’s not the shape of my heart....(Sting, 1993)

Effects of reduced circulatory output

Reduced (aerobic) metabolic capacity

Risk of ischemia in «underprioritized» tissues

Reduced ability to absorb and transport O2

GROWTH IMMUNE RESPONSE

SKIN WINTER ULCERS ?

GILL DAMAGE AGD ?

How can we influence this by nutrition?

Affecting the pathogens possibility to cause damage

via the host’s immune system

Enhancing the host’s ability to maintain important

physiological processes despite damage

flexible and robust organ systems keeping spare capacity

Heart pathology in HSMI transmission trial

• 1 test feed + 1 control

• 4 replicates = 12 tanks=1 test cell

• 100 fish/tank, 20 g + shredder fish

• 1 week acclimatization

• 6 week feeding before challenge

• 14 week challenge

• Cohabitant challenge, i.e. injection of virus in shedder fish that

are put in all tanks

• Sampling:

1. 0-sampling 6 weeks before start. 8 fish

2. After 6 weeks feeding (befor challenge)

3. 3 weeks post challenge

4. 6, 8, 9, 10 and 12 weeks post challenge

We see some very promising indications

Corresponds with documentation from mammals

More analytical work to verify effects

Investigate physiological enhancement as well as

influence on pathology

Conclusions and further work

Thank you !
