The Fishpond Lease Agreement (FLA) system and a Fishpond Permit (FP) system were established in 1937, allowing for rental of government land for aquaculture. [16] Due to the reliance on wild catch to support traditional milkfish ponds, shrimp fry often also ended up in these ponds, and ponds were occasionally contaminated with seaweed.
The Philippine Council for Agriculture, Aquatic, and Natural Resources Research and Development (PCAARRD) is a council of the Department of Science and Technology of the Philippines government. The council aims to help national research and development efforts in agriculture, forestry, and natural resources of the Philippines. It does so by ...
Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
The Kratky method is a passive hydroponic technique for growing plants suspended above a reservoir of nutrient-rich water. [1] Because it is a non-circulating technique, no additional inputs of water or nutrients are needed after the original application, and no electricity, pumps, or water and oxygen circulation systems are required.

One of the drawbacks to recirculating aquaculture systems is the need for periodic water exchanges. However, the rate of water exchange can be reduced through aquaponics, such as the incorporation of hydroponically grown plants [89] and denitrification. [90]
View of the research greenhouse approximately one week after transplant of tomato crop. The tanks are below the wood-grate walkway. Aquaponic systems were in use among the Aztecs in Mexico ca. 1000AD, and such a system was replicated in the US in 1969, when research into those systems began, with researchers from the New Alchemy Institute in Massachusetts and from North Carolina State ...
A run-to-waste hydroponics system, referred to as "The Bengal System" after the region in eastern India where it was invented (circa 1946) This method can be set up in various configurations. In its simplest form, a nutrient-and-water solution is manually applied one or more times per day to a container of inert growing media, such as rockwool ...
Aquaculture (less commonly spelled aquiculture [1]), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. lotus).
