1. What other inferences can you make about the differences between the fish populations of these two sites?

Solution

The inferences that can be drawn regarding fish population are:

1. The first graph implies that increased water temperature effects fish population. The graph is rising which indicates that mean fish population is rising with temperature. It is important to note that fish are poikilothermic animals. Their body temperature changes with the surrounding temperature. According to the graph, the optimum temperature for fish survival in this area is 22 degree C.

2. The second graph relates salinity of water with mean fish population. According to this, the mean fish population rises with increasing salinity. Fish labeled \'J\' survives in highest salinity range.
