This is at least a step in the positive direction.

A quick Google tells me that soy has a yield of 2.81 metric tons per hectare, and seaweed has a yield of ~20 metric tons per hectare. Depending on how much of the feed can be replaced by seaweed additive, it's another arrow in the quiver to reduce the environmental impact of food production, the same way that cheap solar and wind don't displace the need for energy efficiency.

It's a very small amount of seaweed in the feed.
