Freshwater pearl culture practices and challenges in India

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.

Wild seed collection and modified-extensive farming of Mystus gulio in inland water bodies of South 24 Parganas, West Bengal

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.

Farming of the anadromous shad, Tenualosa ilisha: Signs of taking off in India

The andadromous shad Tenualosa ilisha (also known as hilsa) is an economically important food fish in south and southeast Asia. Populations of the species are declining globally, largely due to overexploitation and habitat modification. Its fishery has drastically declined in the Bay of Bengal bordering India. Considering the excessive demand and very high market price there have been efforts for domestication and farming of the species in India. Early efforts were not measurably successful. However, momentum on developing captive breeding and farming technologies for this species has been re-invigorated with research funding from the Indian Council of Agricultural Research.

Global Conference on Aquaculture Millennium +20

The GCA +20 was successfully held as a hybrid event from 22-25 September, with physical participation at the venue in Shanghai, China, and international participation via video conference. A total of 1,728 people participated in the event, of which 500 were physically present in Shanghai. A key output from the GCA +20, the Shanghai Declaration is a call to action that highlights the principles and strategic pathways to maximise the contribution of sustainable aquaculture in achieving the Sustainable Development Goals, with a special focus on “Leaving no one behind”.
