What’s the difference between biological and chemical oxygen demand?
Prof. Boyd explores the commonly used and relevant aquaculture water quality terms biological and chemical oxygen demand (BOD and COD).
New technologies taking on harmful algal blooms
Emerging technologies could make it easier for fish farmers to detect and defeat harmful algal blooms, but expertise will yield best results.
For global nutrition needs, aquatic foods remain overlooked
Aquatic foods can help to deliver resilient global food systems and to support critical periods of human development, a new UN paper determines.
A fresh focus on sea cucumbers – nature’s recyclers
Researchers in Scotland, Sweden and Canada are exploring the potential of sea cucumbers, the squishy detritivores that can help clean up behind fish pens.
Kelp parachutes: Green gravel reforestation projects showing promise
Researchers are growing kelp seedlings on ‘green gravel’ and then scattering them on the ocean floor, where they’ll hopefully anchor and flourish.
Sludge report: Finding value in Norway’s aquaculture waste
Bioretur converts aquaculture waste, or sludge, into fertilizer as demand for “circular economy” technologies grows.
Nutrient recovery from shrimp farming with combined integrated multitrophic aquaculture of polychaete worms, saltworts
Evaluation of IMTA designs showed a single polyculture tank with ragworms and saltwort had best bioremediation performance and biomass production.
Aquaculture, feed companies embark on a carbon-cutting journey
The aquaculture value chain can significantly reduce carbon emissions with innovations in feed, transportation and operations.
Conscious coupling: Can IMTA gain a foothold in Europe?
Integrated multitrophic aquaculture (IMTA) isn’t widely practiced in Europe but new findings indicate that farming multiple species on one site can work.
Utilization of feed and waste from salmon aquaculture by great scallop juveniles
P. maximus could be a candidate for integrated multitrophic aquaculture, with potential to utilize small particles of uneaten salmon feed and fecal waste.
