Qardio and Salmon Lice
Salmon lice determine to a large degree the way in which salmon farming is carried out today. Delousing results in stress for the salmon that can cause mortality and financial loss. Feeding with Qardio can contribute to a more robust and resistant fish.
The frequency of delousing operations per facility has multiplied in recent years, and an increasing resistance to the majority of delousing agents has led to limited efficacy. Both preparatory treatments and non-preparatory treatments involve handling of the salmon, which subjects them to stress.
Large quantities of salmon have been lost in connection with such operations. Low oxygen levels during treatment and increased oxygen consumption in the tissues under stress requires that the heart needs to compensate to meet the oxygen demand. If the heart is not strong enough to meet this challenge, the result may be that the fish dies of circulatory failure.
If heart wall is weakened by ongoing or previous illness, this can give rise to Broken Heart Syndrome (CMS) under the increased pressure. Similarly, reduced gill health leads to lower oxygen absorption and an increased need for cardiac capacity. Qardio contributes to a more robust and resistant fish.
Feeding with Qardio can contribute to a more robust and resistant fish.
Having Qardio as a feed prior to situations where fish are subjected to additional stress can be extremely important. Experiments have shown that the heart wall thickens after feeding with Qardio.
This can affect the heart's effectiveness and its ability to withstand pressure. Infection experiments and field trials have shown that Qardio also brings about reduced viral load and reduced damage to the heart wall after experiencing HSMI and CMS infection.
Delousing weakened fish can cause mortality and financial loss.
Risk factors may include CMS diagnosis and other previous heart disease, high water temperature and reduced gill health.
