Fish farming

terms of physical resources, the company possesses two big indoor fish farms raising barramundi. Turner Falls, at Massachusetts, United State contains two-acres of aquariums, and Central Vietnam farm is the world’s first and only ocean-based aquaculture facility recognized Monterrey Bay Aquariums "Best Choice" rating for sustainability (Thebetterfish, 2015). Owning inland farms, the company can reduce uncertainty in supplying fish because of the high competition for decrease allowable catch rate

eggs and the male sturgeon fertilizes them. Incubation happens for a week until the eggs hatch and the new fish rely on nourishment from a yolk sac until they are further grown. The yolk sac provides complete nourishment for the small sturgeon for its first 12-14 days of life. Similar to salmon entering ocean, sturgeon fish can enter areas with higher salt content to look for food. The fish can spawn once they are mature, with the males reaching it first when they are about 12 to 18 years old. Female

occupation, industry, or season of taking fish or other sea animals (shrimp, squid, clams) and selling them for profit” (Webster Dictionary). Atlantic Cod used to be considered as one of the richest fisheries in the world. Atlantic Cod, scientifically known as,Gadus morhua, are heavily bodied, blunt snouted fish that are typically brown or grayish in color with a series of spots located on their bodies along with a pale lateral line. This species of fish have a schooling behavior when feeding but

Cutting off meat from one’s diet comes with many benefits. For example, energy matters: eating meat is “far less energy efficient than relying on a vegetarian diet (and leaves a far greater ecological footprint),” because in the trophic levels, only 10% of energy moves with each level when an animal consumes another (Withgott PAGE NUMBER). By the time a human consumes meat, they only gain about 30% of optimal energy, versus 90% energy in a vegetarian diet (Withgott). Other benefits include lower

(liberal) start mining the reef, the water quality will deteriorate and the habitats for fish and other sea creatures may get destroyed. Another threat to the great barrier reef is commercial prawn netting, because the nets go down into the reef water and get caught on the coral and can destroy the sea floor. Also catching by-catch destroys the reef because the by-catch may be a parrot fish or a surgeon fish that helps the reef control elegy levels(26). Commercial fishing can also cause species to

50,000 annually (IBISWorld Australia, 2017). Among them, Huon Aquaculture Group and Pearl Corporation of Australia can be considered as major competitors for Tassal. Recently, Huon - the second-largest company in salmon industry – has deployed fish farming offshore which, according to them, will enhance the quality of salmon due to the combination of faster water current and greater level of oxygen (Huon Aquaculture Group, 2016).

Examples of forage fish include sardines, anchovies and herrings. Scientists have shown that catching forage fish instead of cod is a more sustainable approach. According to research from the University of British Columbia Fisheries Center, the forage fish population has more than doubled in the past century (Christensen, 2014). A main cause for the population growth is that human beings

by commercial fishing, single person excessive fishing in a particular area of a body of water, or by other natural predatory activity. A recent report by scientists said that if commercial fish species – the fish caught for food – continue to decline at the current rate, by the year 2048 most commercial fish species will be in danger of never recovering because of the break in the natural ecosystem which would affect the diversity of wildlife in the ocean (Kurlansky, 2011). As a human species,

The downfall of fish in the Atlantic Ocean is a result of numerous factors such as certain fishing techniques, climate change, and pollution. One type of fishing technique that is causing serious damage to marine life is bottom-trawling. Bottom-trawling is a form of fishing that involves a large net, about 60 meters wide, and dragging it along the bottom of the sea with heavy weights from a trawler. Bottom-trawling causes irreversible damage to coral life and slow-growing fish species, for example

Shrimp farming expanded greatly during the 1980s, and now is a multi-billion dollar a year industry (Moss et al., 2006). Although penaeid shrimp naturally inhabit the marine environment, some of them, such as the whiteleg shrimp, Litopenaeus vannamei, are able to tolerate exposure to low salinity, and also to survive and grow well in this type of environment (Roy et al., 2010). The culture temperature range for this species is 26–33°C (Wickins and Lee, 2008), and can endure salinities of 0.5 to 45
