Vienna_31.10.2020 In addition to the fact that brine shrimp [Artemia] are a widely used food item for small or larval fish and crustaceans (see brine shrimp), Artemia provides a unique example of how to develop a strategy in dealing with critical conditions needed for survival. The Artemia model depicts adaptation as a complex response to … Continue reading
Vienna_27.10.2020 I have the feeling that the fish are very fond of Daphnia [water fleas]. Even Heabea, who normally does not leave her separate chamber, came out to hunt the water fleas.
I fed mosquito larvae from a sieve and learned that the fish easily get into the sieve. Next time I know how to catch them if I want to move them to another tank.
Artemia populations are found in about 500 natural salt lakes and man-made salterns scattered throughout the tropical, subtropical and temperate climatic zones, along coastlines as well as inland. Among the live diets used in the larviculture of fish and shellfish, nauplii of the brine shrimp Artemia constitute the most widely used food item. Annually, over … Continue reading
Vienna 24.06.20_04:00 pm When I got home last night, 2point was floating on the surface. I was sure that he was dead; but he wasn’t. He shot away as I approached him.

I remember a funny detail. In one source it was told that the zebra fish in the fish facility in Tübingen … Continue reading
pale is dead. He died on January 19, 2020 and was one of the insatiable fish that often entered the tube loaded with mosquito larvae. I was sad and felt guilty. He was probably overeating and I suspected that the colorless zebrafish mutants were more susceptible than the wild forms. In order to show him … Continue reading
1. December 2019, 03:11 pm I installed a new and longer tube to train the fish to swim through. The tube could be loaded with mosquito larvae from above. It turned out that not all fish got into the tube, while others did so more often and with less hesitation. Spirit of adventure or just … Continue reading
