This factsheet published by the Southern Regional Aquaculture Center (SRAC) gives information on the management of aquacultural effluents from ponds....
A Numerical Comparison of Two Approaches to Commercial-­Scale Aquaponics
Dr Mark McMurtry's comparison of the two schools of aquaponics shows that the media-based, 'flood/drain' approach outperforms, by a wide margin, the hydroponic raft system. Dr McMurtry is widely acknowledged as the creator of the science of aquaponics...
Pollutants Released by Seafloor Trawling Affect Marine Life
Commercial bottom trawling, the technique of pulling fishing gear across the seabed to catch fish and other seafood, releases pollutants trapped in the seabed, which can negatively affect local marine life and ecosystems. Recent findings from a Norwegian...
Ranaviruses: Detection, Differentiation and Host Immune Response
