In general, freshwater fish require salinity (salt) levels of 1.0 ppt or lower. You measure the salinity of a freshwater aquarium to be 3.0 ppt. Predict what will happen to the cells of the fish as a result of the salinity level in the aquarium.

1) Is tank water hyper, hypo or isotonic to the fish cells? Explain why.

2) Based on your answer to part 1, what will this type of solution ultimately do to the cells of the fish? ( which way will the water move into or out of the fish cells?)

1) The tank water is hypertonic to the cells of the fish. Hypertonic solutions are those with higher solute concentrations compared to the sap of the cells placed in them. Hypotonic solutions have lower while isotonic solutions have the same concentrations as the sap of cells placed in them.

2) Because the tank water is hypertonic, the cells of the fish will lose water to the water in the aquarium. When this happens, the cells shrink, and may eventually start dying if the situation remains unchanged enough.
