Fish populations and other aquatic resources are likely to be affected by changes in what aquatic factors?
a. water temperatures
b. disease
c. water quality
d. all of the above

The answer is D. all of the above

d. all of the above

Explanation:

As the fish are dependent on the characteristics of the water and thus water is needed for the and other forms to sustain life and population of the fish will be affected by the availability of the oxygen and other such as sunlight and planktons and thus is affected by the water salinity and density along with the temperatures variations.  The presence of freshwater and mudded water also affects there growth and development and similarly the growth of the population will be affected by the death caused due to the illness in their species.
