Technical Efficiency of Shrimp and Prawn Farming: Evidence from Coastal Region of Bangladesh
Shrimp and prawn farming in Bangladesh have experienced spectacular growth in response to expanding global demand and higher economic return. In 2011, 180 shrimp and prawn farms were surveyed in Bangladesh to estimate their production efficiency and determine factors affecting the efficiency level. The results show that there are substantial inefficiencies among shrimp and prawn farms. The tech...
متن کاملA comparison of development opportunities for crab and shrimp aquaculture in southwestern Bangladesh, using GIS modelling
The present study identifies and quantifies appropriate sites for brackish water aquaculture development in southwestern Bangladesh using remote sensing, GPS and geographical information systems (GIS). A colour composite Landsat TM image from 1996 covering the southwestern part of Bangladesh was used to identify the extent of brackish water and to classify land use. The remotely sensed data wer...
متن کاملEconomics of Shrimp Farming: A Comparative Study of Traditional Vs. Scientific Shrimp Farming in West Bengal
The advent of scientific shrimp farming in India during 1990-91 not only boosted shrimp production but also attracted criticism on the grounds of generating adverse environmental and social impact challenging the sustainability of the system. Thus while examining the performance of alternative shrimp farming systems incorporating of the cost of negative externalities generated by shrimp farming...
متن کاملThe Use of Antibiotics in Shrimp Farming
Global aquaculture has grow dramatically over the past 50 years to around 52.5 million tones in 2008 worth US$98.5 billon and accounting for around 50 per cent of the world ́s food fish supply. Asia dominates this production, accounting for 89 per cent by volume and 79 per cent by value, with China by far the largest producer (32.7 million tonnes in 2008). The rapid growth in the region has been...

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
