oxygen increases so does the number of fish observed. However‚ when the dissolved oxygen reaches 14 ppm the number of fish decreases to 10. So‚ 6ppm and 14ppm‚ 8ppm and 16ppm‚ and finally 10ppm and 18ppm‚ have a similar number of fish observed. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. If the amount of dissolved oxygen is increased‚ then the number of fish observed will increase. 3
