Most rotifers are still produced in large low-density batches, which are a common source of vibrio and other pathogens. Poor quality live feed causes mortality and lost revenue for a hatchery, but the true cost impacts the entire value chain. Animals that survive fighting off early infections often have worse feed conversion ratios and lower growth rates throughout their life, resulting in less profit for the hatchery and grow-outs.
Industrial Plankton’s high-density continuous rotifer system provides a stable culture environment to reliably produce high-quality rotifers day after day, with the additional benefit of significant labor savings.
Water from the 1000L culture tank is recirculated through an attached biofilter, promoting a stable culture of beneficial bacteria to outcompete opportunistic pathogens. To maintain good water quality, organic waste is removed using a mechanical filter, a foam fractionator, and finally ammonia is detoxified in the biofilter.
The rotifer system makes it easy to control vital parameters such as temperature, pH, and dissolved oxygen. The touchscreen automates routine functions like feeding and harvesting, while logging and graphing data in realtime.
High-density continuous rotifer production significantly reduces labor and floorspace, but the primary benefit is biosecurity. Feeding high quality rotifers reduces early infections, resulting in animals with higher survival and growth rates in the hatchery, and better performance during grow-out.
The rotifer culture system is turnkey and easy to install. It minimizes labour and runs continuously, producing high quality rotifers to increase hatchery revenue.
