Philippine aquaculture is hampered by the lack of a "trash fish" — a cheap fish that can be used to feed farmed fish — as most fish in the Philippines are directly valuable for human consumption. This increases the cost of farming carnivorous fish. Another common impediment is access to juveniles, for fish, crabs, and shrimp.
Standard weight equation for largemouth bass [1] and burbot [2] (fish). Standard weight in fish is the typical or expected weight at a given total length for a specific species of fish. Most standard weight equations are for freshwater fish species. Weight-length curves are developed by weighing and measuring samples of fish from the population.
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.

[5] Some municipal fisherfolk continue to rely on traditional methods, including hook-and-line fishing, beach seines, small nets and traps, fish corrals, hand spears, and the manual collection of seaweed and invertebrates.
The use of lighted payaos to attract fish has also had a large impact on catch size and profitability, [7] and by the 1980s over 2,000 commercial payaos were being used in the Moro Gulf alone. [8] By this time most other South Pacific nations had payao programs and were seeking to improve their designs for increased durability for use in open ...

Oyster farming was established in 1931 in Hinigaran, Negros Oriental, using the "broadcast" method where oysters are simply laid on the seabed. In the years afterward it was introduced with new methods to Binakayan in Cavite by the Bureau of Science, leading to the area around Manila Bay becoming the center of oyster farming in the Philippines ...
