Energy Management

Aquaculture is a relatively high energy consumer due to the need for pumping large volumes of water and providing aeration systems for oxygen supply.

At Pacific Reef we have developed power monitoring and management systems to optimise our energy efficiency. Oxygen levels are monitored and aeration levels are adjusted to suit animal needs. We make particular use of the photosynthetic production of oxygen by the algal blooms in the ponds during the day to reduce aeration usage.

We are trialling systems whereby real-time oxygen monitoring linked to automated power control will further optimise this energy efficiency 24 hours per day.

Water management to reduce pumping requirement is also important. Farming methods have evolved to manage animal needs using in pond processes rather than flushing via water exchange. This has drastically reduced the water needs of the farm over the last five years.
