10 Piscicultura semi - intensiva
China was the first country to farm fish, starting over 1,000 years ago. China harvested 24.6 mmt of farmed fish and shellfish in The major fish species cultured are the native carps which are grown together in the same ponds ( polyculture ) fertilized with animal wastes. Fish are also fed agricultural by-products and commercially fabricated fish feeds. China accounts for 70 % of the world harvest of farmed animals and plants.

11 Tilapia Tilapia roja Oreochromis sp
Tilapia nilótica Oreochromis niloticus Tilapia roja Oreochromis sp Tilapia are a group of fishes native to Africa and require warm water for culture. Most tilapia are grey or black colored but a red tilapia was developed with selective genetic breeding because consumers liked the bright colored fish. Tilapia are unable to survive winter water temperatures in open ponds in most of the U. S.. Tilapia can be raised in ponds, cages and tanks depending on environmental conditions and natural resources. Tilapia are raised outdoors year round in tropical climates but can only be farmed outdoors during the summer in the U. S. Thus, most tilapia are raised indoors in the U. S. to assure year round growth.

Marine shrimp are native to all the oceans and seas of the world and numerous species are farmed. Marine shrimp are grown in earthen ponds located in coastal areas of countries with tropical and subtropical climates. Ponds are filled with saltwater pumped from estuaries and oceans. Small shrimp reproduced and raised in captivity are stocked into the ponds and are ready for harvest in 90 to 120 days.

17 de Salmón del Atlántico
Sistema de jaulas para crianza intensiva de Salmón del Atlántico Atlantic salmon are native to the cold freshwater rivers and Atlantic ocean of northern North America and Europe. Salmon grow to adults in the ocean and migrate back to the freshwater stream of their birth to reproduce. Atlantic salmon are farmed in large floating cages placed in clean, cold ocean waters in the northern and southern hemispheres. Atlantic salmon were introduced to the Southern hemisphere 30 years ago.

Alimento balanceado pulverizado Pellet pequeños Pellets grandes Initially, fry are fed with a powdered feed but as they grow, particle size is increased until they are able to consume a small diameter floating pellet. Fingerlings are fed twice daily and water quality in the ponds is monitored constantly to assure a healthy environment. Máquina de distibución de alimento Pellets flotantes

The red swamp crawfish is native to the lower Mississippi river drainage. Swamps and other wetlands are its preferred habit. The crawfish feed on decaying vegetation, aquatic plants, filamentous and attached algae and small benthic animals. They burrow into the soft bottom mud as water levels recede in early summer and remain underground during the summer months. As water levels increase in the Fall and Winter, the crawfish adults and young produced underground leave the burrows to forage on decaying vegetation. Wild crawfish are harvested with baited traps in the Spring. Crawfish are commonly farmed in shallow water ponds used to grow rice. The crawfish burrow during the summer months when the rice is growing. After rice harvest, the rice stubble is flooded and the crawfish leave their burrows to feed and grow on the decaying vegetation. Cultured crawfish are also harvested with traps from the rice fields in the spring. Campos de arroz
