DA-BFAR's Techno Demo Video on Shellfish: Tahong

Introduction to Tahong00:00:05

An overview of the importance of mussels as a nutritious food source, a livelihood for fishermen, and their ecological role in cleaning water.

Broodstock Selection and Spawning00:01:06

Selecting healthy breeders (at least 2-3 inches), identifying gender by gonad color, and using thermal stress techniques to induce spawning in tanks.

Fertilization and Larval Monitoring00:03:01

The process of manual fertilization, collecting eggs and sperm, identifying good versus bad eggs, and monitoring the development of larvae.

Larval Care and Feeding00:06:00

Techniques for stocking density, monitoring larvae, and feeding them brown algae (Isochrysis galbana) twice daily to support early growth.

Settlement and Deployment00:07:56

Introducing substrate nets for larval attachment, transferring them to ropes, and finally deploying them into rafts for grow-out.

Harvesting and Conclusion00:09:51

Maintaining optimal water parameters for growth, harvesting after four to eight months, and the economic potential of the mussel industry.
