Whether commercial fish or ornamental fish – maintaining large fish stocks in a confined area is not easy. Inany case the crucial thing is to offer the animals optimal living conditions and thus maintain the value of thestock.

Healthy, disease-resistant fish

Healthy, disease-resistant fish are the capital of every fish hatchery. Fish only develop in accordance with requirements and a healthy stock is only guaranteed if the water quality is outstanding. With a large fish stock however algae growth can increase dramatically due to the high influx of nutrients caused for example by excreta or remnants of food.

Frequently the entire stock is at risk due to disease or toxic reactions. Consequently many fish hatchery operators – particularly those with large fish stock – rely on OASE for healthy and lively fish at all times.
