Fish faeces and residual feed recovered from salmon hatcheries may soon become a sustainable product. The salmon farming sector will be crying out for a solution to the forecast ‘feed squeeze’.
The issue of salmon feed has become a bottleneck, hindering the growth and sustainability of the Norwegian aquaculture sector. In the future, insect meal, bristle worms and bacteria that consume CO2 may become essential components of a farmed salmon’s diet.
Researchers had the crazy idea of feeding ragworms with locally-cultivated seaweeds. The results were as gold-edged as the worms themselves – a high-quality, locally-sourced and sustainable feed for farmed salmon.
Omega-3 fatty acids are essential components of healthy diets for both humans and fish. The dramatic increase in fish farming worldwide has boosted the demand for omega-3 fatty acids so much that today’s supply can’t meet demand. Reducing waste and finding new sources can help.
The electronic “sensor” fish measures the physical factors that affect farmed fish during delousing. The results may lead to welfare improvements in salmon farm cages.
The amount of omega-3 fatty acids in farmed salmon is dropping. But a reasonable and affordable solution may make salmon even healthier to eat.
