FAQ - frequently asked questions
What is the planting density?
Depends on the area of the trays, the number of shelters and feeding regime. We calculate the density after consultation according to your goals.
What to feed ACCR?
Compound feed for crustaceans with calcium and protein additives; We set up feeding schedules and the ability to automate.
How to ensure the survival of juveniles?
We use shelters, age separation, stable water parameters and controlled feeding.
Do I need to prepare the water?
Yes, filtration and adjustment of pH and salinity are necessary. We install a salt unit, osmosis and preparation systems for the task.
Do you need a quote for your volume and time frame?
Describe the task - we will prepare the configuration, estimate and launch schedule.
