Why is fisheries sustainable in the economic role of rivers only when water quality is good?

Answer and explanation

Correct answer: Because polluted water harms fish habitats, breeding and survival

Good water quality provides adequate dissolved oxygen, fewer toxic pollutants and a suitable aquatic habitat. This supports fish survival and breeding, allowing fisheries to provide income over the long term. In contrast, polluted water can reduce oxygen and introduce harmful substances, lowering fish populations. Exam tip: link fisheries with river health, livelihoods and water pollution.
