What is the primary purpose of fisheries?
Fisheries primarily serve to meet global protein demand by harvesting aquatic organisms like finfish, shellfish, and aquatic plants. These resources contribute significantly to human nutrition, providing essential proteins, vitamins, and minerals.
How are marine and freshwater fisheries distinguished?
Marine fisheries involve harvesting fish from oceans and seas, while freshwater fisheries focus on inland water bodies such as lakes, rivers, and ponds. This distinction is based on the aquatic environments where fish are caught.
What are the key components of aquaculture?
Aquaculture, or fish farming, involves various practices such as pond aquaculture, cage culture, and recirculating systems. These methods provide controlled environments for raising fish and other aquatic organisms, contributing to sustainable seafood production.
What role do fishing quotas play in fisheries management?
Fishing quotas limit the amount of fish that can be caught to prevent overfishing and maintain sustainable fish stocks. These regulations ensure the long-term viability of fisheries and help conserve marine ecosystems.
How does ecosystem-based management differ from traditional fisheries management?
Ecosystem-based management considers broader ecological impacts, aiming to preserve biodiversity and ecosystem health while managing fisheries. It takes into account the interactions between species and habitats, promoting sustainable fishing practices.
