Summary This video from ICAR - Central Island Agricultural Research Institute demonstrates the complete culture process of Vannamei shrimp using biofloc technology. It details the steps from seed procurement, disinfection, and acclimatization to stocking in biofloc culture tanks. The preparation of biofloc inoculum with jaggery and probiotics, along with feeding and regular monitoring of floc volume, are highlighted as crucial management practices. The video concludes by showcasing the harvesting process, where a 10,000-liter tank can yield approximately 30 kg of marketable shrimp in about 120 days. Biofloc technology is presented as an efficient, sustainable, and profitable aquaculture system that maximizes productivity with limited resources, offering significant income generation opportunities for farmers. The system uses 10,000-litre tarpaulin-lined biofloc tanks equipped with standby power supply to ensure continuous aeration. Healthy PL-10 shrimp seed is stocked at a high density of 3,000 shrimp/m³ and reared on formulated pellet feed under continuous aeration. Systematic biofloc development, regular water-quality monitoring, carbon supplementation, adequate aeration and optimised feeding management help maintain stable culture conditions throughout the 100–120-day production cycle. Video Transcript Biofloc technology for Vannamei shrimp. Seed procurement - Healthy Penaeus Vannamei shrimp seed at the PL. Healthy PL-10 shrimp seed is stocked at a high density of 3,000 shrimp/m³ Seed disinfection - Before stocking, the seed packets are disinfected using a potassium permanganate. Acclimatization - Following disinfection, the seed packets are floated in the biofloc culture tank to allow gradual acclimatization. This process helps the shrimp adjust to the tank's water temperature and environmental conditions. Water quality assessment and stocking. - Prior to stocking, essential water quality parameters, including salinity, are carefully monitored. Once the conditions are found suitable, the shrimp seed is gently released into the culture tank. Biofloc inoculum preparation - To establish the biofloc system, jaggery and commercial probiotic bacteria are mixed in 100 liters of water and continuously aerated. After approximately 48 hours, the prepared biofloc inoculum is introduced into the culture tanks. Feeding and biofloc management - Shrimp are fed with nutritionally balanced commercial feed with pellet size adjusted according to their growth stage. Jaggery solution is periodically added as a carbon source to support biofloc development. The floc volume is regularly monitored using an Imhoff cone to maintain optimum culture conditions. Growth monitoring - Periodic growth assessment is carried out using a check tray. Harvesting - At the end of the culture period, the water level is reduced and the shrimp are harvested using hand nets. During harvesting, total biomass, average body weight, and average length are recorded to assess overall production performance. Production and marketing - Under proper management, a 10,000 liter biofloc culture tank can produce approximately 30 kilograms of marketable shrimp within a culture period of around 120 days. The harvested shrimp are sold directly to consumers and local markets, generating a profitable return for farmers. Biofloc technology has proven to be an efficient, sustainable, and profitable aquaculture system. By utilizing limited land and water resources more effectively, it enables farmers to achieve higher productivity while maintaining environmental with proper scientific management. Biofloc-based shrimp farming offers excellent opportunities for income generation.
