The solunar theory is a hypothesis that fish and other animals move according to the location of the moon in comparison to their bodies. [1] The theory was laid out in 1926 by John Alden Knight, but was said to be used by hunters and fishermen long before the time it was published.
Pond-reared broodstocks benefit from the removal of predation which can be a significant cause of mortality in natural populations. [16] They further benefit from the removal of variable environmental impacts. Holding broodstock in an accessible pond or tank offers readily available breeding adults whenever required.
Of fish ponds being leased from the government, the majority are leased by individuals with addresses in different locations to those of their fish ponds. Almost all freshwater fishponds are privately owned. [16] Fish pond land can be leased from the government for a minimum of 25 years and a maximum of 50 years under the Fisheries Code of 1998.
Ram feeding and suction feeding are on opposite sides of the feeding spectrum, where extreme ram feeding is when a predator swims over an immobile prey item with open jaws to engulf the prey. Extreme suction feeding is demonstrated by sit-and-wait predators that rely on rapid depression of the jaws to capture prey (e.g., frogfish, Antennariidae).
Aquaculture is the farming of fish and other aquatic life in enclosures, such as ponds, lakes and tanks, or cages in rivers and coastal waters. China's 2005 reported harvest was 32.4 million tonnes , more than 10 times that of the second-ranked nation, India , which reported 2.8 million tonnes.
Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture , which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans , molluscs and so on, in natural or pseudo-natural environments.

The Hawaiian fishpond was primarily a grazing area in which the fishpond-keeper cultivated algae; much in the way cattle ranchers cultivate grass for their cattle. [3] The porous lava walls let in seawater (or sometimes fresh or brackish water, as in the case of the "Menehune" fishpond near Līhuʻe, Kauaʻi), but prevent the fish from escaping.
