Penaeid Shrimp Research Paper

Decent Essays
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 ppt, and recent studies suggest that it can possibly be cultured at salinity below 0.5 ppt (Prapaiwong, 2011). Actually, there is a significant percentage of all farmed penaeid shrimp is reared in low salinity water (Flaherty et al., 2000). There is considerable interest in culture of the Pacific white shrimp Litopenaeus vannamei (Boone) far from coastal areas in inland ponds filled with low-salinity (2-5 ppt). In southern USA, this tropical species is cultured in earthen ponds in a temperate climate when water temperature permit shrimp growth and survival, which is usually limited to early May through late October (Green, 2008). However, there are wide variation in shrimp performance among ponds. For example, in inland low-salinity ponds in Alabama, feed conversion ratio…show more content…
In general, the rate of physiological processes increase as the temperature and oxygen concentration increase (Buentello et al., 2000). The main controlling factor for fish or shrimp feeding, metabolism, and growth is temperature. The growth rate is reduced if the energy demand of increased metabolic rate exceeds the gain from increased food consumption (Brett, 1979). When the food supply is not limiting, the specific growth rate of most aquatic species increases with rising temperature (Talbot,
