Sea Urchins

In Metlakatla, sea urchin larvae land on hanging culture gear in large numbers, and they grow very well with no care and attention until reaching a size of about a centimeter, when they fall to the bottom. Low prices would make intensive culture impractical, but these "natural" seed could be transported to rocky habitats for final grow out. It may be necessary to provide seaweed on ropes to assure good growth or to optimize the quality of the edible gonads.

Also, short-term, feed-lot operations to optimize the size and quality of the roe (gonads) of low-grade, commercially harvested sea urchins might be profitable.
