I would pass on using this. Composted poultry manure is likely to elevate ammonia levels leading to algae. The nutrients in feather and bone meal are not very bio-available to plants. This is the reason you see so many CFUs (colony forming units) listed. The bacterial and fungi colonies are used to break down the organic materials into a more usable form. I doubt they would survive in an aquatic environment.
Also, it does not provide the essential trace elements. The level of calcium is very high as well. There are much better options available.
