Aquaculture Quiz

How does freshwater aquaculture differ from marine aquaculture in terms of location and species cultivated?

• Uses salt pans and Artemia salina

• Located inland; cultivates tilapia and catfish

• Uses open sea cages for sea bass

• Requires high salinity levels

What environmental factors make brackish water suitable for milkfish and mangrove crabs?

• Rich oxygen and plankton levels

• High elevation and clay soil

• Deep water and low salinity

• Artificial reef structures

Compare the species cultivated in freshwater and marine aquaculture systems.

• Marine uses catfish; freshwater uses sea bass

• Both use mangrove crabs

• Freshwater uses carps; marine uses rabbitfish

• Both use tilapia

Which aquaculture environment requires careful site selection for salinity and depth?

• Freshwater

• Brackish

• Marine

• Metahaline

Analyze the suitability of rice paddies for aquaculture.

• Ideal for seaweed farming

• Effective for freshwater species like tilapia

• Suitable for marine fish

• Used for predator-prey systems

What distinguishes brackish water aquaculture from freshwater systems in terms of species and water composition?

• Uses only saltwater

• Uses deep lakes for catfish

• Requires artificial reefs

• Mixes seawater and freshwater

How does cage culture vary across fixed, floating, and submerged systems?

• Only fixed cages are used in freshwater

• Floating cages are used in salt pans

• Each type adapts to different water conditions

• Submerged cages are used for seaweed

Compare pole culture and long-line culture in terms of structure and species farmed.

• Both use bamboo frames

• Pole culture uses oak stakes; long-line suspends ropes

• Long-line is for oysters; pole is for catfish

• Both are used in freshwater ponds

What is the function of artificial reef culture in marine aquaculture?

• To reduce salinity

• To cultivate freshwater fish

• To support biodiversity and ecosystem health

• To manage predator-prey systems

How does raft culture differ from rack culture in terms of materials and species supported?

• Raft uses steel racks; rack uses bamboo

• Raft supports mussels; rack supports intertidal organisms

• Both use floating cages

• Rack culture is used in salt pans
