Aquaculture Asia Magazine

Aquaculture Asia Magazine is an autonomous publication that gives farmers and scientists in developing countries a voice. Stories concern the small-scale aquaculture prevalent in the region and the circumstances of farmers trying to make ends meet in an increasingly globalised world. We accept articles on any aspect of aquaculture and the related processing, marketing, economic, environmental and social issues. An RSS feed is available if you wish to stay informed of new issues.

Collection of tubifex worms from the Adi Ganga canal, West Bengal as means of livelihood

Nutrient-laden canal water from Kolkata is the lifeline of two communities: Firstly the fish farmers beyond the eastern fringes of Kolkata who depend upon domestic sewage of the dry weather flow channel as a source of nutrients to sustain plankton production in fish ponds/wetlands; and secondly, the semi-poor city people, who harvest the tubifex worms (Tubifex tubifex) as a livelihood, from a stretch of derelict waterway named Adi Ganga. This article describes the practices of tubifex collectors and the market chain for the worms.

Some facts for the grow-out culture of an endangered catfish, Clarias magur

Although relatively slow growing, market demand for Clarias magur is sufficient to make it economically attractive for aquaculture. Supply of this species is through a combination of wild caught and cultured fish. However, a drastic reduction in wild populations has led to C. magur being listed as endangered by the International Union for Conservation of Nature. Only limited quantities of cultured fish are available. The article communicates the aquaculture practices of C. magur including hatchery, nursery and grow out.

The cryptic domain of gut microbiota in composite culture of Indian major carps

The digestive tract of all vertebrates including fish is known to harbour a complex microbial ecosystem with a large, diverse and dynamic collection of microorganisms. These microbes become an integral component of the host animal with intimate host-microbe associations. In the following study, we employed both bacterial enumeration and culture independent DNA fingerprinting approach to examine the presence of host-specific gut microbiota in Indian major carps related to their occupancy of distinct ecological niches.

Integrated rice-fish farming in hilly terraces of the Apatani Plateau, Arunachal Pradesh

Rice-fish farming is a popular activity amongst the Apatani tribe of the Ziro valley, conducted in their wet rice terraces. The strains of fish cultured include mirror carp Cyprinus carpio specularis, scale carp C. carpio communis and leather carp C. carpio nudus, cultivated synchronously with local rice cultivars (Oryza sativa), viz. eamo, ampu, mipya, pyapu, pyaping and eylang. This article describes the integrated farming practices and socio-economic circumstances of the Apatani in the Yachuli, Hapoli, Hong, Hari, Hija, Bula, Dutta and Old Ziro villages.
