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.
When people discuss the tropics, it is normal to use generalized labels to group together similar tropical areas. Common terms would include the humid-tropics (rainforests); the arid-tropics (deserts and dry areas); or monsoon zones (those areas that have well defined wet/dry seasons and experience monsoons). Such labeling is very useful when ...
Shrimp farming causes approximately a quarter of the destruction of mangrove forests. [ 106 ] [ 107 ] Likewise, the 2010 update of the World Mangrove Atlas indicated that approximately one fifth of the world's mangrove ecosystems have been lost since 1980, [ 108 ] although this rapid loss rate appears to have decreased since 2000 with global ...
In some regions the fish can be raised in rice fields at planting time and grow to edible size (12–15 cm, 5–6 in) when the rice is ready for harvest. Unlike salmon, which rely on high-protein feeds based on fish or meat, commercially important tilapiine species eat a vegetable or cereal-based diet.
The largest tropical rainforest, the Amazon Rainforest covers much of northwestern Brazil and stretches into other South American countries. The 2,300,000-square-mile wonderland of biodiversity is ...
Tropical rainforests have existed on earth for hundreds of millions of years. Most tropical rainforests today are on fragments of the Mesozoic era supercontinent of Gondwana. [13] The separation of the landmass resulted in a great loss of amphibian diversity while at the same time the drier climate spurred the diversification of reptiles. [10]
The farming of fish is the most common form of aquaculture. It involves raising fish commercially in tanks, fish ponds, or ocean enclosures, usually for food. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery.
Rainforest with emergent trees in Taï National Park. As of 2016, 3660 species of vascular plant had been recorded in Ivory Coast. [4] The Ébrié Lagoon is dominated by mangroves and herbaceous vegetation including both rooted and floating aquatic plants. Further inland are extensive swamps with larger herbaceous plants and small trees. [5]
