[1]: 35 Milkfish dominates marine fish cages production, making up 99.91% of output. [ 1 ] : 36 Milkfish similarly dominates marine fish pen production, making up 98.38% of the total. [ 1 ] : 37 However, the largest mariculture product is seaweed, the production of which made Bangsamoro the most productive fisheries region in 2020.
Fish being laid out to dry at a market in Mariveles. From 1980 to 2010 capture fisheries were dominant, making up 82% of fish volume caught, of which 89% was marine and 11% freshwater, although aquaculture has since increased in prominence. [3]: 8 Municipal fisheries and aquaculture combined produced 73% of all catch from 2011 to 2020. [35]
From 2013 to 2022, municipal capture fishery production has declined across 10 of the 17 regions, most significantly in the Central Visayas region where production decreased 42.61% (32,867.51 metric tons) over that time. Production in Bangsamoro, Metro Manila, and the Davao Region went against the overall trend, increasing during this time.
Capture includes fish, crustaceans, molluscs, etc. [1] [2] [3] World capture fisheries and aquaculture production, from FAO's Statistical Yearbook 2021 [ 4 ] ↑ By species group
The 1.75 million MT of farmed seaweed produced made the country the world's third-largest producer. Aside from seaweed, marine production made up 5% of produce, with brackish water and freshwater making up 12.5% each. There were 790,900 tonnes of fish produced, making up 25.4% of all fish production.
Thorson's rule (named after Gunnar Thorson by S. A. Mileikovsky in 1971) [1] is an ecogeographical rule which states that benthic marine invertebrates at low latitudes tend to produce large numbers of eggs developing to pelagic (often planktotrophic [plankton-feeding]) and widely dispersing larvae, whereas at high latitudes such organisms tend to produce fewer and larger lecithotrophic (yolk ...
Marine shrimp farming is an aquaculture business for the cultivation of marine shrimp or prawns [Note 1] for human consumption. Although traditional shrimp farming has been carried out in Asia for centuries, large-scale commercial shrimp farming began in the 1970s, and production grew steeply, particularly to match the market demands of the United States, Japan and Western Europe.
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.
