Collection of tubifex worms from the Adi Ganga canal, West Bengal as means of livelihood; Some facts for the grow-out culture of an endangered catfish, Clarias magur; The cryptic domain of gut microbiota in composite culture of Indian major carps; Integrated rice-fish farming in hilly terraces of the Apatani Plateau, Arunachal Pradesh.
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.
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 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.
