A significant amount of fish by-products is produced during fish processing. These by-products represent 20-80 percent of the fish and provide a good source of macro- and micronutrients. Yet they often go unutilized, when they can easily be converted into a variety of products including fishmeal and oil, fish hydrolysates, fish collagen, fish sauce, fish biodiesel and fish leather. The production of fish silage using organic acid is a good example of the simple and inexpensive conversion processes which can be employed. Fish silage production uses minced by-products or minced whole fish unsuitable for human consumption as raw material, before adding a preservative to stabilize the mixture -- usually an organic acid such as formic acid. The process breaks down protein into free amino acids and small-chain peptides which have nutritional and antimicrobial properties, therefore, the fish silage can be used as healthy feed and fertilizer. The feasibility studies on fish waste management in Bangladesh, Philippines and Thailand outline existing good practices on the utilization of by-products and fish waste. Furthermore, the insights provided on the potential production and utilization of fish silage in each country are promising in terms of increasing the productivity of the fisheries sector, reducing post-harvest waste, increasing economic value and improving environment sustainability.

The article reports on the approval for the commercial cultivation of the Bt brinjal by the National Committee on Biosafety (NCB) in Bangladesh. It says that four Bt brinjal-approved varieties have been developed by the Bangladesh Agricultural Research Institute (BARI), with the help of technology that was transferred by India based Maharashtra Hybrid Seeds Co. Ltd. It indicates that Bangladesh is the first country to allow the entry of any edible genetically modified crops in its market.

The article discusses the prospects for the Indian textile industry in 2013. According to the author, China, Bangladesh, and Vietnam have emerged as the biggest threats to India in the world market. The author adds that the increasing cost of production, including raw material, labour, and transportation, is an important factor that has hampered the competitiveness of Indian textiles.

The article discusses the influx of illegal Bengali immigrants to India as of January 2011. It states that due to frequent flooding, a burgeoning population and political tensions, the number of Bengalis crossing over to India through West Bengal has risen steadily. It claims that in 1951, 22% of Bangladesh's population were Hindus, but as of the current year, it stands at 7%. Muslims too, have begun to cross over, increasing the state of West Bengal's population well above that of the rest of India. Many are helped by touts on both sides of the border.
