The Gangetic mystus (Mystus cavasius) is a small indigenous freshwater catfish valued for its taste and nutritional qualities, with high market demand across South Asia. This article offers a practical guide for farmers on the captive breeding and production of M. cavasius, encompassing key stages from broodstock management to grow-out culture. Captive production methods are critical for ensuring seed availability and enhancing the commercial viability of this species. The article outlines protocols for brood selection, hormone-induced breeding, egg fertilisation, larval rearing, and fingerling development, with emphasis on water quality, feed regimes, and optimal stocking densities.
Special attention is given to improving larval survival through early indoor rearing, proper husbandry, and the use of live and formulated feeds. The slow-growing nature of M. cavasius necessitates low-density stocking and extended grow-out periods, typically yielding less than 1 tonne/ha/year. Despite the modest productivity, the species commands strong regional demand at 30–40 g market size. The guide also addresses common health issues and preventive practices, stressing the importance of water quality and early disease intervention.
This article examines recent initiatives to rejuvenate primary Fisher Cooperative Societies (FCSs) in South 24 Parganas District, West Bengal, highlighting their critical role in advancing sustainable fisheries, rural livelihoods, and social protection. It outlines the structural, administrative, and policy frameworks that support FCS operations, particularly the government’s lease-based allocation of large freshwater bodies to cooperatives. The article also reviews the election procedures conducted under the West Bengal Cooperative Societies Act to reconstitute governance in 43 active societies, ensuring compliance and eligibility for state support.
Through detailed case data and programme reports, the article documents the outcomes of targeted schemes such as input distribution for sewage-fed and large-scale fish culture, equipment provisioning, pension benefits, and capacity-building training. It emphasises the cooperative model's effectiveness in managing natural resources, strengthening community self-governance, and enhancing productivity. With a focus on practical reforms and institutional accountability, the South 24 Parganas experience offers insights into scaling cooperative-led fisheries development in similar socio-ecological contexts.
India's brackishwater aquaculture sector, particularly shrimp farming, holds immense potential but remains largely underexploited despite its significant contribution to global shrimp production and exports. Small-scale farmers, who form the backbone of this industry, face substantial challenges including limited access to credit and insurance, poor management practices, and vulnerability to disease outbreaks and extreme weather events. These risks lead to considerable crop losses and hinder the sector's stability and growth. This article underscores the critical role of crop insurance as a vital risk management tool to mitigate these financial losses, secure livelihoods, and promote the sustainable development of shrimp aquaculture in India.
This article details the risks associated with shrimp farming, such as climatic events, disease outbreaks, market volatility, and financial constraints. It also outlines comprehensive risk management strategies, including the adoption of better management practices, biosecurity measures, and contingency planning. The article identifies key challenges faced by both farmers and insurers and presents innovative solutions and strategic recommendations for developing more effective and inclusive shrimp crop insurance products.
With the implementation of new aquatic animal disease reporting arrangements from January 2021 NACA is publishing reported aquatic animal diseases submitted by countries in the Asia-Pacific region. This report covers the fourth quarter of 2024 and the original and updated reports can be accessed from the QAAD page.
The project evaluated the effectiveness of various types of nature-based solution (NbS) in Fiji that contribute to climate change resilience by enabling off-grid farm operations and reducing reliance on costly fossil fuels. Aquaculture enterprises were assessed for this project based on the NbS they utilised and the potential benefits they offer in mitigating climate change impacts and enhancing production systems in Fiji. Four enterprises were selected, and their descriptions are provided within.
