Effect of temperature and salinity in Mysidopsis juniae reproduction

Cultivation of Daphnia similis Species in Standard Conditions

“…This fact can lead to the emergence of males and females with two resistant eggs. These resistant eggs, fertilized by males, are surrounded by a thickening dark color in the incubation chambers of adult females, called ephippium (Figure 6) [4][5][6]. Therefore, if one or more cases of ephippium occur in a culture, the neonates produced in this culture should not be used, having to discard and reassess the cultivation procedures.…”

“…From the 3 rd to the 7 th day, they mature for reproduction (depending on the species) [4]. It has an anatomy (Figure 1) that allows easy locomotion through the antennae and an abdominal region that allows food particles to be filtered and conducted to the mouth [5,6].…”

“…These Daphnia species applied in ecotoxicological tests allow a study of acute effects (quick responses for organisms exposed to some compound) and chronic effects (responses with extended periods of exposure, which may lead to deleterious effects to organisms, such as immobility). The ecotoxicological tests occur through neonates obtained by reproducing young or adult Daphnia (7 to 21 days of age) [6].…”
