Question
Which of the following is main cause of fish killing in ponds a.All b.Algal Bloomc.DOd.pHClear my choice
Solution
The main cause of fish killing in ponds is b. Algal Bloom.
Algal blooms are a rapid increase or accumulation in the population of algae in freshwater or marine water systems. They are often green, but they can also be other colors such as yellow-brown or red, depending on the species of algae.
Algal bloom can cause significant harm to fish and other aquatic animals because it can deplete the oxygen in the water as they decompose, and some algal blooms produce toxins that are harmful to the health of the ecosystem. This can lead to large-scale fish kills.
So, your choice b. Algal Bloom is correct.
