There are about 100 penaeid shrimp species in China’s coastal waters, of which a dozen Penaeus spp. and Metapenaeus spp. have commercial value (Liu 1989a). The main species cultured in China are Penaeus chinensis, P. monodon, P. japonicus, P. merguinsis and P. penicillatus. Chinese shrimp farms are distributed along almost 18,000 km of coastline from Hainan Province in the tropics to Liaoning P...

The shrimp is an excellent source of protein and essential HighUnsaturated Fatty Acids (HUFA) such as eicosapentaenoic (20: 5n3, EPA) and docosahexaenoic (22: 6n3, DHA) acids [1, 2]. Furthermore, the shrimp is also a good source of minerals and vitamins such as calcium, iron, zinc, copper, vitamin B12, essential amino acids [1, 3] as well as astaxanthin, a fat-soluble carotenoid which has antio...

A survey of 101 shrimp farms in Ecuador revealed that the average annual yield based on production pond water surface area was 7.03 ± 0.93 (SE) t/ha/year. The range among five provinces with 3.67 0.71 to 11.95 5.56 t/ha year, respectively. Averages for total land, water, and energy use were 0.54 0.01 ha/t shrimp, 76,817 6,330 m3/t 61.2 4.2 GJ/t Average wild fish meal oil included feed 0.65 0.02...

The protective efficacy of oral delivery of a DNA construct containing the VP28 gene of WSSV encapsulated in chitosan nanoparticles was investigated in black tiger shrimp (Penaeus monodon). The results showed that significant survival was obtained in WSSV-challenged shrimp at 7, 15 and 30 days post-treatment (relative survival, 85%, 65% and 50%, respectively) whereas 100% mortality was observed...

The effects of single and combined use of two different probiotic bacterial species, Bacillus licheniformis and Lactobacillus rhamnosus on growth performance of Pacific white shrimp Litopenaeus vannamei was evaluated. Shrimp were treated with probiotics in entire crop duration with different test diets. Twelve culture ponds were divided into four groups of each three, Control (CP) without probi...

this study was conducted to evaluate the possibility of white leg shrimp (litopenaeus vannamei) culture twice a year in nayband agro-industry complex in 2010. three earth ponds (0.8 ha) were selected in the farm which had similar conditions in terms of culture system, postlarvae age (pl12) and stocking density (37-38 pl m3). the first period of shrimp culture started from mid april and they wer...

BACKGROUND Artemia (brine shrimp) is used as feed for fish fry and shrimp in aquaculture. Two employees in a Norwegian aquaculture research farm reported having chest symptoms when working in an Artemia hatch room. AIMS To determine the presence and prevalence of Artemia sensitization at the farm and the extent of any Artemia-related respiratory and hand skin symptoms and to identify the alle...

In shrimp/fish aquaculture, feed represents the most expensive production cost. The quantity and quality of diets are primary factors influencing shrimp/fish growth, health status, disease prevention, pound contamination and expenses. Utilization of probiotic bacteria has emerged as a solution with enormous applications in the aquaculture feeding industry. Bacillus species principally B. subtil...
