AQUACULTURE FACILITIES [objectives] Describe the common types of facilities used in aquaculture Discuss site selection Identify and assess construction methods in aquaculture facilities Describe the equipment needed in aquaculture List and explain the components of recirculating aquaculture tank systems

WATER FACILITIES – ch.10 Levee-type ponds – an earthen wall is formed on nearly level land and filled Watershed ponds – created by damming a natural valley or stream Raceways – rapidly moving water Cages – can be used to protect small fish from larger fish and are versatile Tanks – closed systems often used for small fish

SITE SELECTION Levee-type ponds – adequate supply of clean water, soil that holds water (clay), suitable terrain Watershed ponds – between 5 and 25 acres of watershed needed per acre of water surface Raceway ponds – flowing source of water Cage sites – natural movement of new water and sufficient depth Tank sites – access to roads, suppliers, and utilities; water source; use for discharged water
