Biology and culture of Daphnia pulex (Leydig) under temperate conditions in Kashmir

K K VASS, H S RAINA

Abstract


Biological studies on the growth and reproduction of Daphma pulex under temperature conditions show that at an ambient temperature range of 19-25c this species within a life span of 18 days has 6 pre-adult and 12 adult instars. Studies on the longevity,growth,egg production, and embryogenesis of this organism vis-a-vis different qualities of light and various temperature ranges have been highlighted. A technique to mass culture Daphnia pulex has been developed to yield a maximum density of about 9000 org/l in two weeks.

Keywords
