Study Notes
Overview of Inland Fisheries
- Inland fisheries refer to the extraction of fish and other aquatic organisms from inland waters, which have long provided food for humans.
- Inland fisheries face threats from human activities such as damming, navigation, wetland reclamation, urbanization, and water extraction.
- Capture fisheries involve harvesting fish and other aquatic organisms from natural habitats like oceans, rivers, and lakes.
- Aquatic resources management aims to sustainably manage freshwater and marine ecosystems to ensure responsible use of aquatic resources.
- Aquaculture, or fish farming, involves controlled cultivation of aquatic organisms in various environments.
- Post-harvest activities include processing and marketing of harvested aquatic organisms.
- Inland fish is an important source of nutrition and food security, particularly in low-income food deficit countries.
- Inland fisheries have a lower resource use footprint compared to livestock or other protein dense foods.
- Inland capture fisheries employ millions of people, with women playing a significant role.
- Freshwater ecosystems are heavily impacted by human activities, leading to biodiversity loss.
- Freshwater ecosystems house over 40% of the world's freshwater fish species.
- The Philippines has several notable lakes, such as Laguna de Bay, Lake Lanao, Taal Lake, Lake Mainit, Naujan Lake, Buluan Lake, Pantabangan Lake, Lake Bato, Pulangi Lake, and Lake Buhi.
