The correct answer is: c) Wetland areas.
Fisheries play an important role in Assam’s economy, primarily in wetland areas. The state has a long coastline and a large number of rivers, lakes, and wetlands. These provide a habitat for a variety of fish species, which are harvested for both commercial and subsistence purposes. The fisheries sector employs a large number of people and contributes significantly to the state’s GDP.
Option a) is incorrect because high altitudes are not conducive to the growth of fish. Option b) is incorrect because desert regions are also not suitable for fisheries. Option d) is incorrect because hilly regions are not as productive as wetland areas for fisheries.
Wetland areas are important for fisheries because they provide a variety of habitats for fish, including spawning grounds, nursery areas, and feeding grounds. They also help to regulate water levels and provide a buffer against floods and droughts. Wetlands are also important for other reasons, such as providing a habitat for wildlife, protecting water quality, and storing carbon.
