That's sustainable business versus environmentally sustainable. Again, I'm not a scientist in any way, so I'm probably the wrong person to ask. There are certain criteria that have been established that deem what is environmentally sustainable.
A lot of it is management of resources. We have to remember that, like any farm initiative, the product we feed our fish has to come from sustainable sources as well. When we're taking non-sustainable fish, grinding it down, and feeding that at a higher ratio than the actual weight of product that we're getting out of the product, that certainly is not sustainable.
Those are some of the criteria that have been established to deem whether that is sustainable.
There are going to be open-net pens that are going to be able to produce one pound of fish by using less fish protein than the one pound they're gaining. Those would be sustainable alternatives to the other groups that are going to use a lot more fish protein in their feed.
Those are just some of the criteria that would establish whether it's sustainable or not.
Again, it's also management of resources and your ability to manage well, whether it's escapement, predation, or your impact on benthic environment. There are going to be groups out there that are highly focused on producing a product that has very little impact on the environment; that's really going to be the difference between whether it's well managed and focused on environmental impact and a group that's not necessarily focused on that at all.
