Health test for salmon smolt may improve survival chances
Nofima scientists have developed a test that measures the immune status of salmon smolt that could increase the smolts’ chances of survival.
Dissolved oxygen is a major concern in aquaculture. Here’s why.
Demand for dissolved oxygen is high in modern, intensive aquaculture, so DO concentration must be continuously maintained by mechanical aeration.
