are many different methods of farming fish. Described below are
both sustainable and less sustainable types of aquaculture:
– Farming system that preserves and
enhances the environments where it is located while at the same
time maintaining productivity, using ecosystems thinking.
– Focuses on the integration and connectedness of all parts
of the operation including the animals, input of nutrients, the
environment and the wastes produced. Follows set of organic standards
that other certified producers follow.
Polyculture and Integrated
Aquaculture – Farming method where diverse organisms
are raised within the same system each operating within its own
unique niche to contribute to the entire system. Wastes from one
organism are used as inputs to another.

– Land based tanks with constantly flowing water and highly
controlled environment. Can be installed in many locations. Ideal
Inland Pond Culture
– The earliest type of aquaculture, this is the most common
system used to farm freshwater fish. Consists of freshwater ponds
stocked with fish.
– Saltwater aquaculture including coastal and offshore operations
in addition to saltwater ponds and tank systems. Often uses netpens
or cages to grow fish.
