Overfishing in Bihar’s rivers and wetlands can lead to:

Depletion of fish stocks
Loss of biodiversity
Reduced livelihoods for fisherfolk
All of the above

The correct answer is: All of the above.

Overfishing is the removal of a large percentage of fish from a population, which can lead to a decline in the population’s size and health. This can have a number of negative consequences, including:

  • Depletion of fish stocks: Overfishing can lead to a decline in the number of fish in a population, which can make it difficult for the population to recover. This can have a knock-on effect on other animals that rely on fish for food, such as birds and mammals.
  • Loss of biodiversity: Overfishing can also lead to the loss of biodiversity, as it can remove key species from an ecosystem. This can disrupt the balance of the ecosystem and make it more vulnerable to other threats, such as climate change.
  • Reduced livelihoods for fisherfolk: Overfishing can also have a negative impact on the livelihoods of fisherfolk, as it can reduce the number of fish that are available to catch. This can lead to job losses and poverty in coastal communities.

It is important to manage fisheries sustainably to avoid the negative consequences of overfishing. This can be done by setting limits on the number of fish that can be caught, and by protecting areas where fish can breed and grow.
