BACKGROUND Black tiger shrimp Penaeus monodon is one of the common causes of shellfish allergy that is increasing worldwide. One of the important problems in the management of shellfish allergy is the lack of accurate diagnostic assay because the biological and immunological properties of allergens in black tiger shrimp have not been well characterized. This study aims to detect proteins with t...
In Bangladesh, black tiger shrimp (Penaeus monodon; Fabricius, 1798) aquaculture has come to be one of the most important sectors in both the rural and national economies. Likewise, organic shrimp aquaculture has emerged as an alternative farming enterprise for farmers especially in the southwestern districts of Bangladesh. The present study aims to show key performance characteristics of organ...
A study on problems and prospects of shrimp production and marketing from Bangladesh on the basis of secondary information was carried out from July to October 08. Shrimp farming has emerged one of the important economic activities in Bangladesh and become the second largest export industry after garments. Shrimp aquaculture in coastal areas plays a major role providing employment, income and f...
The global aquaculture of penaeid shrimp has grown rapidly during the past two decades. In 1998, world shrimp farmers produced an estimated 737 200 t of whole shrimp (this includes 530 200 t from the eastern hemisphere and 207 000t from the western hemisphere), a record 12% increase from the 660 200 t produced in 1997 (Rosenberry 1998, 1999). The shrimp farming sector suffered a serious setback...
Mixed rearing of tilapia (GIFT; Genetically Improved Farmed Tilapia) with shrimp (Penaeus monodon) in brackishwater rice-shrimp system was assessed for its impact on dry season's shrimp production. The experiment was conducted in pre-selected farmer's field located at Paikgacha Upazila of Khulna district and designed with three different densities (treatment) of GIFT, viz, 0.3, 0.4 and 0.5/m2 w...
The co-culture of juvenile sea cucumber Holothuria scabra (Jaeger), or 'sandfish', with juvenile blue shrimp Litopenaeus stylirostris (Stimpson) was tested by growing groups in co-culture and monoculture for 3 weeks in tanks with enriched sand substratum. Feed was supplied on trays, accessible only to shrimp. Survival of shrimp and sandfish was high in all treatments (73–100%). Growth of shrimp...
The paper explores the trade competitiveness of seven major shrimp exporting countries, namely Vietnam, China, Thailand, Ecuador, India, Indonesia and Mexico, to the USA. Specifically, we investigate whether the United States (US) antidumping petitions impact upon the bilateral revealed comparative advantage (RCA) indexes for each of the seven shrimp exporting countries with the USA. Monthly da...
سنگ های آذرین پساافیولیتی با ترکیب ریولیت/داسیت در داخل مجموعه افیولیتی پهنه سبزوار رخنمون دارند. ماهیت کالک آلکالن و آداکیتی پرسیلیس این سنگ ها پیش از این به اثبات رسیده است. این سنگ ها حاوی مقادیر نسبت های ایزوتوپی نخستین 87sr/86sr (70382/0 تا 70444/0) و nd(t)ε (30/5+ تا 18/6+) مشابه با ترکیبات بازالت پشته میان اقیانوسی (morb) هستند. این ویژگی های ایزوتوپی با ترکیبات آداکیتی حاصل از ذوب ورقه ...
Within the past decade, viral diseases have emerged as serious economic impediments to successful shrimp farming in many of the shrimp-farming countries of the world. In the western hemisphere, the viral agents of Taura syndrome (TS) and infectious hypodermal and haematopoietic necrosis have caused serious disease epizootics throughout the shrimp-growing regions of the Americas and Hawaii, whil...
