Integrated Multi-Trophic Aquaculture (IMTA)
IMTA involves cultivating species from different trophic levels together to create a balanced eco-system. Shellfish, seaweeds, and finfish are commonly raised together.
Raceway Systems
Raceway systems consist of rectangular tanks or channels with a continuous flow of water, commonly used for trout and salmon farming.
Shrimp Farming
Shrimp farming involves the cultivation of shrimp in marine or freshwater systems. Various species like Penaeus vannamei (whiteleg shrimp) are cultivated.
Flow-through Systems
Flow-through systems use a constant water source such as a stream to flow through tanks or ponds. Species like trout and salmon are often reared in this system.
Biofloc Technology
Biofloc technology uses microbial communities to break down waste materials in water, creating a protein-rich food source for species like shrimp and tilapia.
Pond Systems
Pond systems are man-made bodies of water where aquatic organisms are reared. Freshwater fish like catfish, tilapia, and carp are typically cultivated.
Polyculture
Polyculture is the concurrent cultivation of multiple aquatic species in one system, such as rice-fish farming. Species combos can include carp and tilapia.
Recirculating Aquaculture Systems (RAS)
RAS are tank or enclosure systems where water is filtered and reused, minimizing the need for fresh water. Species like tilapia, bass and ornamental fish are typically cultivated.
Open Net Pens or Cages
Open net pens or cages are suspended in the water column, allowing for natural conditions such as water flow. Species typically cultivated include salmon, trout, and tuna.
