I think a lot about light, how everything is food.
How everything I design is works within a closed system. Nothing leaving, nothing coming in; nothing new. Everything re-distributed and remixed though different feedback loops.
Even stored sun-light. How often I find myself explaining food.
“The higher the trophic level the harder it is to digest because. .. You’re eating more bonds; stored sunlight, more time- food.”- Muscle protein compared to salad greens.
So question is: If I give salmon the light- from the bird’s eye point of view
As I’m designing the factory trawler and thinking about how everything is food re: regulations on bycatch I wonder if fish can see and manure around nets; if correctly designed, could we engineer nets to be seen from a fish’s point of view?
What if we could designed nets for both the fish we do and don’t want to catch, visibly not just physically? Can we manipulate the light- the technology of the nets?

Spider Webs Inspire Bird-Safe Glass Ultraviolet light reflects off the center of spider webs and allows birds in flight to avoid collision, benefiting both bird and spider.
A spider’s ability to protect its web from predators has recently inspired the development of window glass that prevents birds from striking it. Research conducted on the decorative patterns of spider webs, technically known as the stabilimenta, found that the center decorations serve as a warning signal to birds. Birds are capable of perceiving ultraviolet light reflecting off the silk and altering their path to avoid the webs. Depending on the direction of light, spiders create denser designs to provide more surface area for reflection. Studies indicate that the presence of a decorative center on spider webs reduces damage from flying birds.
The reflectivity of the stabilimenta inspired a company in California, Arnold Glas, to design an insulated glass sheet called ORNILUX. The glass has a unique ultraviolet-reflective coating that appears almost transparent to humans but is clearly perceptible to birds. The coating mimics the reflectivity and patterns of spider silk. The use of ORNILUX reduces bird collisions by 77% compared to standard window glass.

If you have the time, read it. It highlights bycatch- unintended catch from a different point of view.

The net ladder: Essentially it’s a 1’x1′ square of soft canvas distributed through out the net. The canvas catches the water creating a pool for fish to rest then repeat the process until they’ve found their way out. The design is being developed by a company in the Amendment 80 fleet; I only know of it because, as luck would have it, I was there at the right time.
