  • Cryopreservation Division: Implements technologies to preserve fish genetic material (such as sperm and eggs) for future breeding programs.

2. Significance of NBFGR for Fisheries and Aquaculture in India

India is one of the world’s largest producers and consumers of fish, with a diverse array of fish species spread across its freshwater and marine ecosystems. Given this, the role of NBFGR becomes indispensable in ensuring the sustainability and advancement of the fisheries and aquaculture sectors. Here’s how the NBFGR contributes:
a. Conservation of Fish Genetic Diversity
India has a rich diversity of indigenous fish species, many of which are found only in specific geographical regions or habitats. The NBFGR works to conserve these species, some of which are endangered due to overfishing, habitat degradation, and climate change. The institute’s efforts in gene banking, cryopreservation, and ex-situ conservation of fish genetic resources help safeguard these species from extinction.
  • Cryopreservation Techniques: The NBFGR has pioneered the development of cryopreservation techniques to store fish sperm and embryos, ensuring the availability of genetic material for future breeding programs. This is particularly crucial for endangered species or those facing environmental challenges.
  • Conservation of Endemic Species: The bureau focuses on conserving species that are endemic to Indian rivers, lakes, and coastal areas, such as the Indian Mahseer and Hilsa fish, which have unique genetic traits suited to specific environments.
b. Genetic Improvement for Aquaculture and Fisheries
The NBFGR plays an important role in improving fish species for enhanced productivity in both aquaculture and capture fisheries. It achieves this through:
  • Selective Breeding: The institute employs selective breeding techniques to enhance desirable traits such as faster growth rates, better disease resistance, and improved reproductive performance in various species.
  • Genetic Fingerprinting: By using molecular techniques like DNA fingerprinting, the NBFGR ensures the traceability of fish stocks and the integrity of aquaculture practices. These genetic technologies help in the identification of superior genetic strains.
  • Hybridization Programs: Hybridization of different species or populations with superior genetic traits can lead to hybrid fish that possess higher yields and are more resistant to diseases.
c. Enhancing Aquaculture Sustainability
With the growing global demand for fish products, aquaculture has become a major contributor to India’s fish supply. NBFGR’s contributions to the genetic improvement of fish species are crucial to making aquaculture more sustainable. Sustainable practices ensure that fish farming is economically viable, environmentally responsible, and able to meet growing food demands.
  • Disease-Resistant Strains: NBFGR has developed genetically improved strains of fish that are more resistant to common diseases in aquaculture, thereby reducing the need for antibiotics and chemicals that can harm the environment.
  • Adaptive Strains: The bureau works on breeding fish strains that can thrive in various environmental conditions, such as high water temperatures or low oxygen levels, ensuring that aquaculture can adapt to changing climates and environmental stressors.

3. Role of NBFGR in Enhancing Food Security

With fish being an essential source of animal protein, the genetic resources provided by the NBFGR contribute directly to ensuring food security. The bureau’s work in developing high-yielding, disease-resistant fish strains directly benefits the availability and affordability of fish for human consumption.
a. Contribution to Nutrition
Fish is a rich source of protein, omega-3 fatty acids, and essential vitamins and minerals. By improving fish production and making fish farming more efficient, NBFGR’s initiatives play a key role in enhancing nutritional security, especially in coastal and inland areas where fish forms a major part of the diet.
b. Boosting Fish Production
India is the second-largest producer of fish in the world, and improving fish production is essential to meet the growing demand for seafood. Through its genetic research, the NBFGR helps increase the productivity of fish species, ensuring that aquaculture can meet both domestic needs and export demands.

4. NBFGR’s Contributions to Research and Innovation

The NBFGR’s research has been pivotal in furthering the understanding of fish genetics, aquaculture, and conservation biology in India. Here are some key contributions:
a. Molecular Genetics and Fish Biology
NBFGR has pioneered research in fish molecular genetics, contributing to the development of DNA barcoding and genetic mapping techniques. This research has greatly advanced the understanding of fish species, their evolutionary history, and the genetic diversity within populations.
b. Eco-Friendly Fish Farming Techniques
As part of its research mandate, the NBFGR has also worked on developing environmentally sustainable and cost-effective fish farming techniques. These techniques focus on minimizing the environmental impact of fish farming while improving overall fish yield.
