Please inform procedure on how we should dump garbage created on the ship without affecting the fishes and sea life.

Recently I had an opportunity to go on a cruise(NCP) and found the garbage was completely dumped in the sea for marine life. Dancers threw the butt of their cigarettes in the Sea. Was concerned for the fishes & ocean health,  as I have a beautiful gold fish in our fish tank.

Awaiting your answer.
