Colour widow tetra: A new and highly preferred aquarium fish in West Bengal

Known as ‘glow widow tetra’, ‘glow skirt tetra’, ‘colour widow tetra’ in the ornamental fish industry, a genetically modified variety of the black widow tetra Gymnocorymbus ternetzi is the most favoured by aquarium fish hobbyists in West Bengal. Stunning and sparkling red, blue, yellow, green, pink, orange, and purple bodied colour variations of this tetra have been developed through gene transfer or transgenic technology. The fish glow when kept under blue LED lights, hence the name ‘glowfish’.

First report on successful captive breeding of peacock eel, Macrognathus aral

The peacock eel Macrognathus aral is a popular ornamental and food fish species found in the Eastern Ghat region of India and Pakistan, Sri Lanka, Bangladesh, Nepal and Myanmar. The species is classed as Low Risk near threatened in the CAMP report. Peacock eel inhabits shallow waters of plains, wetlands, canals, paddy fields, beels and slow-moving rivers with vegetation. Captive breeding is the only way to fulfil demand and protect wild stocks. This article documents the first successful reported captive breeding of M. aral, embryonic development and larval rearing.

Present status of medium saline ‘bheri’ fishery and integrated mangrove-aquaculture in West Bengal, India, Part 2

This is part 2 of an article describing farming practices in bheri systems in West Bengal, India, including their integration with mangrove aquaculture. Since the late 1960s, brackishwater rural aquaculture in West Bengal grew and improved at a fast rate, from an extensive method of farming to a modified-extensive method. Part 2 discusses brackishwater polyculture in South 24 Parganas, including the experiences of farmers implementing an integrated mangrove-aquaculture project, and information on local bheri fisheries derived from published articles.
