BACKGROUND From 2001-2003 monodon slow growth syndrome (MSGS) caused severe economic losses for Thai shrimp farmers who cultivated the native, giant tiger shrimp, and this led them to adopt exotic stocks of the domesticated whiteleg shrimp as the species of cultivation choice, despite the higher value of giant tiger shrimp. In 2008, newly discovered Laem-Singh virus (LSNV) was proposed as a nec...

The total haemocyte count (THC), phenoloxidase activity, respiratory burst, superoxide dismutase (SOD) activity, phagocytic activity and clearance efficiency in response to pathogen Vibrio alginolyticus were measured when the white shrimp Litopenaeus vannamei (18.4 +/- 1.2 g) were injected individually with noradrenaline at 10(-8), 10(-7) and 10(-6) mol shrimp(-1). For the shrimp that received ...

The Deepwater Horizon oil spill impacted Louisiana's coastal estuaries physically, chemically, and biologically. To better understand the ecological consequences of this oil spill on Louisiana estuaries, we compared the abundance and size of two Gulf shrimp species (Farfantepeneus aztecus and Litopeneus setiferus) in heavily affected and relatively unaffected estuaries, before and after the oil...

The effect of ambient ammonia, hypoxia and combination of both on survival and the physiological and immunological response of the blue shrimp Litopenaeus stylirostris in relation to molt stage was studied. Shrimp were submitted to 44.0-71.5 mg l1 total ammonia-N corresponding to 2.0 mg l1 unionized ammonia NH3-N and/or to 1.5 mg O2 l1 (4.3 kPa) for 24 hours. Survival was recorded and the molt ...

With the increasing demand for research on shrimp disease recognition to assist far-off farmers who need proper assistance their farming, prediction is still in initial stage. Most current methods utilize vision-based models, which mainly face challenges: symptom detection and image quality. Meanwhile, there are few researches language-based get over issues. In this study, we will experiment wi...

The artificially manufactured probiotics having beneficial bacteria, Bacillus spp. was applied regularly in a modified extensive shrimp (Penaeus monodon) culture pond, located on the bank of Vellar estuary, Parangipettai. The populations of total heterotrophic bacteria (THB), beneficial bacteria (Bacillus spp.) and pathogenic bacteria (vibrios) were monitored in water and sediment of the pond. ...

Objective: Phytochemical screening as well as several bioassays was performed on the extracts of aerial parts of Caragana jubata. Methods: Extraction of C. jubata was carried out by solvents of increasing polarity. The Phytochemical screening of extracts was carried out using standard procedures. Furthermore, extracts were also evaluated for (i) antibacterial assay, (ii) brine shrimp lethality ...

Shrimp production in Thailand has historically been undertaken in the saline and brackish waters of coastal mangroves. In recent years rising demand and prices for shrimp and falling productivity of mangrove areas have motivated an expansion of shrimp production into the fresh-water margins of river estuaries that were previously used for rice cultivation. Generalised additive models, which off...

Background Food allergy is apparently increasing and it is estimated that 3–4% of adults have food allergy. Shrimp is one of the most common causatives in seafood allergy. Patients with shrimp allergy may exhibit life threatening anaphylactic reactions. Tropomyosin is a known important allergen in shrimp. The IgE-binding epitope in shrimp tropomyosin, cross-reacts with other allergenic inverteb...
