In a noteworthy development, researchers at the ICAR-Central Marine Fisheries Research Institute (CMFRI) have achieved captive breeding of golden trevally (Gnathanodon speciosus), a highly valued marine fish species.
Research Process
- Location: The achievement was made at CMFRI’s Visakhapatnam Regional Centre.
- Duration: The success came after five years of dedicated research efforts.
- Milestone: Successful bloodstock development, captive breeding, and larval rearing were accomplished.
Significance
- New Avenue for Seafood Production: This achievement is expected to open up new possibilities for sustainable seafood production.
- Boost to Mariculture: It will also enhance the mariculture activities in India, particularly sea cage farming.
- Economic Impact: The farm-gate value of golden trevally is estimated to be ₹400-500 per kg, indicating its economic significance.
Characteristics of Golden Trevally
- Ideal Candidate for Mariculture: Due to its fast growth rates, good meat quality, and high market demand, golden trevally is an ideal species for marine aquaculture.
- Appearance: Silver grey with yellowish coloration on the belly, scattered black patches, yellow fins, and a black tail.
- Ornamental Value: Juveniles have golden coloration with black bands, making them attractive for aquarium keeping.
Research Team and Leadership
- Team Leader: Ritesh Ranjan, Senior Scientist at CMFRI’s Visakhapatnam Regional Centre.
- Director’s Statement: A Gopalakrishnan, Director of CMFRI, highlighted the significance of this milestone in Indian mariculture.
Impact on Fish Farming
- Sea Farming Potential: Golden trevally’s desirable qualities make it suitable for sea farming.
- Sustainable Fish Farming: Captive breeding offers opportunities for sustainable fish farming practices, including sea cage farming.
- Contribution to Conservation: This technology can also contribute to wild stock restoration efforts through initiatives like sea ranching.
