Exploration of canal resources as a potential source for fish production in the Indian Sundarbans; Expansion of new host range of isopod Tachaea spongillicola infestation to fish species could pose a risk to aquaculture food industry in southeast Asian countries; Aspects of air-breathing fish farming practiced at Mathurapur-II Block, West Bengal, India; Magical role of live foods in boosting spawn survival of climbing perch: A success in the farmer’s field; NACA Newsletter.
Climbing perch inhabit water bodies ranging from fresh to brackish waters across a wide range of environments, and are widely distributed throughout south and southeast Asia through to southern China. In India it is prized both as a foodfish and as a traditional medicinal food. This article describes the induced breeding of climbing perch and the interaction of scientists and farmers to improve survival of larvae and fry in through the use of live feeds (rotifer) in small-scale hatcheries in India.
Climbing perch Anabas testudineus is a high-priced fish, nutritious and economically profitable for small- to medium-scale fish farmers, who can obtain fry from local paddy fields and low-lying inundated areas in late summer, monsoon and post-monsoon periods. Climbing perch is a facultative air-breathing fish that is able to move between water bodies by undertaking short migrations overland. This article describes techniques for climbing perch and major carp aquaculture, including use of biofloc systems, preparation of live feeds including mealworms, and some concerns regarding the hybridisation of native Indian strain of A. testudineus with an imported Vietnamese strain.
Our article in the journal Aquaculture highlighted the first record of the isopod Tachaea spongillicola infesting wild fish species of aquaculture importance, particularly of carps. T. spongillicola was first recorded in freshwater sponges, 114 years ago and later recorded infesting freshwater prawns. Our recent study has further recorded infestation of this isopod in wild fish species. The expansion of host range from freshwater sponges to freshwater prawns and now to freshwater fish could pose a risk to aquatic industries in the years to come. We hypothesise that climate change could be a major factor contributing towards the expansion of the host range of parasites.
Fisheries is next to agriculture in offering employment opportunities for poor rural communities in Sundarbans. With around 17 million hectares of canals in India, there is considerable potential to generate jobs and improve the food security of rural populations if canals can be used for aquaculture production. This study explored the feasibility of aquaculture as a secondary use of canal infrastructure through use of net barrier partitions, installed and managed by local communities.
Habitat breeding and seed rearing of a near threatened featherback, Chitala chitala; Wild seed collection and modified-extensive farming of Mystus gulio in inland water bodies of South 24 Parganas, West Bengal; Freshwater pearl culture practices and challenges in India; Next generation probiotics: Future therapeutics for sustainable aquaculture; NACA Newsletter.
In 1987, ICAR-CIFA initiated research on the culture and production of freshwater pearls and since then it has been working towards the development of the technology of producing pearls in freshwater environments. Though the breeding protocol for seed production of Lamellidens marginalis is under progress, the culture practice for pearl production has already been standardised. This article describes the culture practices used for freshwater pearl farming in India, including site selection, implant techniques, post-operative care and growout conditions. Challenges and future prospects of the industry are also discussed.
The cultivable small- to medium-sized bagrid catfish Mystus gulio is an estuarine species sold as a high-priced food fish in retail markets in cities and towns of southern West Bengal. M. gulio is a good addition to mixed species culture-based fisheries in canals in the Indian Sundarbans region. It adapts and grows well in freshwater ponds and is recommended for freshwater fish culture in areas of the Sundarbans vulnerable to saline water intrusion. This article describes the seed collection, nursery and grow-out practices of M. gulio as practiced in modified-extensive mixed culture systems in West Bengal, India.
