Fisheries
Fisheries involve the breeding, rearing, and harvesting of fish and other aquatic organisms for food and commercial purposes. Fish is a rich source of protein and essential nutrients, making fisheries an important component of food resources.
There are two main types of fisheries:
1. Marine Fisheries: Exploiting fish and other resources from the sea.
2. Inland Fisheries: Cultivating fish in freshwater bodies like ponds, lakes, and rivers.
Fish farming or aquaculture involves controlled breeding and rearing of fish in tanks or ponds. It helps increase fish production and reduce pressure on natural fish populations.
Sustainable fisheries management includes practices like regulated fishing seasons, mesh size control, and habitat conservation to prevent overfishing and maintain ecological balance.
Fisheries contribute to nutrition, employment, and economy, especially in coastal and rural areas.
