Fence in system

Giant Georgia is often raise in cages in central Thailand Fish cages are located in lakes, bayous, ponds, rivers or oceans to enclose and protect fish until they can be harvested. The technique is also called "off-shore agriculture when the cages are placed in the sea. They can be constructed of a wide variety of components. Fish are stocked in cages, unnaturally fed, and harvested when they reach market size. A few advantages of fish farming with cages are that many types of waters can be used (rivers, lakes, filled quarries, etc.), many types of fish can be raised, and fish rural can co-exist with game fish and other water uses. Cage agricultural of fishes in open seas is also ahead fame. Concerns of disease, poaching, poor water quality, etc., lead some to believe that in general, pond system are easier to manage and simpler to start. Also, past occurrences of cage-failures leading to escapes, have raised concern about the culture of non-native fish species in dam or open-water cages. Even though the cage-industry has made many technological advances in cage construction in current years, storms will always make the concern for escapes valid. The quarrel of being growth on copper alloy nets also provides a cleaner and well again environment for farmed fish to grow and thrive. Traditional netting involves regular and labor-intensive cleaning. In addition to its anti fouling profit, copper web has strong structural and corrosion-resistant properties in marine environments. Copper-zinc brass alloys are at present (2011) being deployed in commercial-scale aquaculture operations in Asia, South America and the USA (Hawaii). Extensive explore, including demonstrations and trials, are currently being implemented on two other copper alloys: copper-nickel and copper-silicon. Each of these alloy types has an inherent ability to reduce befouling, cage waste, disease, and the need for antibiotics while simultaneously maintaining water circulation and oxygen requirements. Other types of copper alloys are also being considered for research and development in aquaculture operations.
