Frequently asked questions

There are a number of reasons why artemia nauplii die - ranging from the quality or contamination of the water being used, through the quality and amount of administered food, and hygiene conditions during breeding to the utilisation of suitable breeding containers. We recommend the German book “Artemia – Der Urzeitkrebs” by Oliver Drewes and published by VIVARIA Verlag. This book uses numerous microscope images and drawings to describe the seven currently recognised types of artemia. After a detailed description of the special reproductive biology, the most successful breeding systems are presented. A chapter entitled “Artemia in der Aquaristik” provides practical tips on how, for example, to improve the hatch and survival rate of nauplii and artemia.

The majority of complaints we have processed were caused by water inside the casing and / or a corroded battery. The thermometers worked perfectly again after allowing them to dry for four days with the cover open and replacing the old battery. Therefore, always remember to retighten the compartment cover correctly after replacing the battery.
