Tropical Barramundi fry (at 25mm) are purchased from hatcheries outside New South Wales - either in South Australia, Victoria or Queensland. Once they are Quarantined and feeding, the production process starts. After approximately four weeks of very rapid growth, the fry can be moved to the Nursery Tank system. With such rapid growth, individual fish can easily outpace their tank-mates in size, so they must be graded almost weekly to overcome this uneven growth rate. Larger fingerlings will damage (or eat) smaller fish resulting in stock losses that can quickly add up when you are managing 10’s of 1000’s of fish. Grading is done with little stress, using baskets with spaced bars in the bottom. Smaller fish slip through into a tank of equal-sized fish, and the over-sized ones move up a grade. We have three Nurseries, each holding fish as they grow to a size of 75g over 16 weeks. At this time they are ready for the Grow-out modules.

Our daily routine of water testing, grading, feeding (x2) and tank maintenance means that staff are attending to the well-being of the fish seven days a week.

The Grow-out modules of three 10,000 litre tanks is their home for a further 16 weeks until harvest.

Barramundi are a fish that responds well to heavy stocking in the tanks, and grow well. The Food Conversion Ratio in our system is excellent – 1.2kg food :1kg fish (1.2:1).

Two days before harvest feeding is stopped, enabling the fish to empty their system of wastes. We call this ‘purging’, aimed at removing any off-flavours from the flesh.

Ideally, at harvest, each module produces in excess of 3,000kg of fish, ranging from 600g to 800g each.

Our name, Tailor Made Fish Farms, was chosen to reflect the way our system operates. We can produce ‘tailor-made’ fish of any size, grown  to suit a banquet or a plate. It’s all a matter of timing and good management.
