The correct answer is a) Decline in fish stocks.
Overfishing is the removal of a large percentage of fish from a population, causing it to decline. This can happen when too many fish are caught, or when they are caught at a young age before they have had a chance to reproduce. Overfishing can have a number of negative consequences, including:
- A decline in the number of fish in the population, which can lead to the extinction of some species.
- A decline in the size of fish, as smaller fish are more likely to be caught.
- A decline in the diversity of fish species, as some species are more vulnerable to overfishing than others.
- A decline in the health of fish populations, as overfishing can stress fish and make them more susceptible to disease.
- A decline in the economic value of fisheries, as overfishing can lead to a decline in the catch.
In Kerala, overfishing has led to a decline in fish stocks. This has had a number of negative consequences, including a decline in the availability of fish for local people, a decline in the income of fishermen, and a decline in the health of the marine ecosystem.
Option b) Increased fish imports is incorrect because overfishing can lead to a decline in the catch, which would make it more difficult to import fish.
Option c) Improved fish biodiversity is incorrect because overfishing can lead to a decline in the diversity of fish species.
Option d) Decreased prices is incorrect because overfishing can lead to a decline in the availability of fish, which would make it more expensive.
