Aquaculture: Current Market for High Value Crustaceans

936 Words4 Pages
There is a great deal of demand in the current market for high value crustaceans such as shrimp, crabs and lobsters. Developed western societies have a higher economic status, giving the country more spending power to purchase unconventional luxury items such as these. As a result, the traditional shrimp trawling industry have near exploited the wild shrimp population, leading to an increase in aquaculture production by exotic species. These are species that have been translocated outside the range of their natural distribution. Aquaculture is used to help keep up with demand while not having an adverse effect on the species wild population. Asia accounts for over 90% of the total global aquaculture production and 80% of market value (De Silva et al., 2009). This is dependent on a significant number of exotic species, however introduction of these species whether accidental or deliberate has been known to negatively impact local biodiversity. Controlled, farm raised production of a species can bring about many benefits to the local area, as well as the country as a whole. Although negative impacts have arisen in aquaculture, some of which are unpredictable, but measures are put in place to help prevent these problems from taking further effect. Aquaculture faces constant pressure to make production more resource efficient and have less impact on the environment. This is usually applied by stricter management practices to help improve the overall performance of each individual farm. Numerical indicators and different out-growth techniques are used to compare resource usage and waste build up in common aquaculture species (Boyd et al., 2007). Indicators are used to represent the efficiency of feed, its nutrients and protein conte... ... middle of paper ... ...s well as a plentiful production of crustacean species to meet the demand in the global market.
