Hilsa (Tenualosa ilisha) is highly favoured as a food fish by consumers but has a complex life cycle and has proven very difficult to breed. Domestication of hilsa requires extra effort while nurturing the larval stage, which is very sensitive and susceptible to mortality. This article describes standardised protocols developed by the Kalyani Field Station of the ICAR-CIFA Regional Research Centre, Rahara, for artificial fertilisation, incubation and larval rearing of hilsa, as the first steps towards the goal of hilsa domestication and culture.

Soft-shell mud crab production for export in Purba Medinipur, West Bengal, India https://enaca.org/?id=1244&title=soft-shell-mud-crab-production-for-export-in-purba-medinipur%2C-west-bengal%2C-india

In West Bengal wild-caught juvenile and sub-adult orange-clawed mud crabs Scylla olivacea are purchased by farms for grow out, fattening, and the production of soft-shell crab for export. This article describes the management practices for producing soft-shell mud crab at National Aqua Farm, using individual box enclosures, and their subsequent processing and packing for export. Details of the crab rearing unit are provided, along with observations of moulting cycles and post-harvest management of soft shell mud crab.

Recreational fisheries in Uttarakhand https://enaca.org/?id=1243&title=recreational-fisheries-in-uttarakhand

Establishing recreational fisheries in Uttarakhand's highland lakes and river systems offers new opportunities to generate livelihoods and income for hill people. The development of catch-and-release sport fisheries can also contribute to conservation of aquatic biodiversity through development of captive breeding technologies, supportive breeding based stock enhancement, and community participation in management of both fishery and habitat. This article describes established and emerging sport fisheries in the highlands of Uttarakhand including for mahseer, goonch and brown trout. It also addresses as yet unrealised opportunities for establishment of recreational fisheries identified through geoinformatic approaches, and partnerships between local communities and government in natural resource management.

A pilot of integrated mangrove-aquaculture as a nature-based solution to mitigate climate change in West Bengal, India https://enaca.org/?id=1242&title=a-pilot-of-integrated-mangrove-aquaculture-as-a-nature-based-solution-to-mitigate-climate-change-in-west-bengal%2C-india

Nature-based solutions are interventions that aim to protect, restore and sustainably manage natural and modified ecosystems to benefit human well-being and biodiversity and address societal concerns. Integrated mangrove-shrimp farming or simply aquaculture is the coexistence of mangroves and shrimp aquaculture in a tide-fed environment. In comparison to other shrimp farming systems, integrated mangrove-shrimp farming can additionally produce timber and supports biodiversity. To understand the possible benefits of mangrove integration, our consortium compared three integrated mangrove-aquaculture systems together with three local farmers in North 24 Parganas. This article describes our findings, and important factors to consider before deploying integrated mangrove-aquaculture systems.

Sustainable livelihood model for coastal families through seabass fingerling production: A success story https://enaca.org/?id=1237&title=sustainable-livelihood-model-for-coastal-families-through-seabass-fingerling-production%3A-a-success-story

Brackish waters offer good prospects for future aquaculture development, as there are fewer competing uses for these resources. Kilarkollai Village (Tamil Nadu, India) has brackish waters on the village periphery, which are under utilised. The majority of the population are landless poor, economically and socially marginalised, and live below the poverty line. A team from the ICAR-Central Institute of Brackishwater Aquaculture demonstrated nursery rearing technologies in partnership with four Scheduled Caste families from the village, with a view to providing supplementary livelihoods and income. The team provided training, initial inputs and technical support.
