The correct answer is option 2: Coastal fisheries.

Coastal fisheries refer to the fishing activities conducted in the coastal areas of India, including the shallow waters near the shoreline as well as the estuaries, lagoons, and mangrove ecosystems. These coastal regions provide a rich and diverse ecosystem that supports a large variety of fish species.

Coastal fisheries are considered the most important source of fish catch in India due to several reasons. Firstly, the coastal areas have a high concentration of fish populations, as they provide ideal breeding and feeding grounds. Secondly, the proximity of these regions to human settlements and fishing communities makes them easily accessible for fishing activities. Additionally, the coastal areas benefit from a favorable climate and nutrient-rich waters, which contribute to the abundance of fish populations.

While the other options also contribute to the overall fish catch in India, they are comparatively lesser in terms of importance. Deep-sea fisheries involve fishing activities in the open ocean beyond the coastal areas and require specialized vessels and equipment. Inland natural fisheries refer to fishing activities conducted in freshwater bodies like rivers, lakes, and reservoirs. Inland cultural fisheries involve fish farming and aquaculture practices in controlled environments. However, the coastal fisheries remain the most significant source of fish catch in
