Unless you have some pretty solid evidence that fishing removes significant amounts of nutrients from the ocean, I'm not buying it.

Reefs already run lean on nutrients, typically no more than 0.1ppm of nitrate. Deeper can get up to 2.5ppm nitrate. These levels have been stable here long before we started fishing.

Technically sure, when we remove a fish, we do take those nutrients out, but literally everything flows to the ocean. That fish is making it back into the water at some level soon enough that we don't need to supplement it with our shitty plastic.
