The prize: SEEDS (random assortment)

This will be a 2 part scavenger hunt. Find and upload or link each of the following:

Part1
A research paper or other scientific publication on: how protein content in fish feed affects Tilapia growth.

Part 2
A research paper or other scientific publication on: the amount of ammonia released into the water as a function of fed protein content in fish feed (any fish).

(Said another way, if we feed this much feed that is 20% protein we get this much ammonia, but if we feed 30% protein we get this much ammonia, etc.)
