The net is now editing its own catch
the net is now editing its own catch: smartrawl sorts fish in the water before the codend with ai vision, shrimp trawls cut sea turtle bycatch up to 90 percent, and sharkguard cut shark bycatch 91 percent in tuna longlines.
the sea now returns what it never wanted.
Context
Fisheries Innovation Scotland describes Smartrawl as an in-water sorting device fitted inside a trawl net extension, using a stereo camera and AI to identify and size animals in real time so unwanted catch can be released. Heriot-Watt University researchers are developing it.
The project ran in phases funded by the UK Seafood Innovation Fund.
The Smartrawl design and in-water sorting match the sources. The 90 percent turtle bycatch cut in shrimp trawls and SharkGuard's 91 percent shark bycatch cut were not seen in the excerpts read, so unsupported here, not refuted.
'The sea now returns what it never wanted' is the author's opinion.

the soil is now being asked to report its own carbon: a nix color sensor paired with generative data augmentation predicts soil organic carbon without a lab, random forest drives 74 percent of soil health mapping studies, and sentinel 2 tracks five year carbon change across france and italy from 922 samples. the dirt now files its own carbon account.
