Fekunditas Caridina Laevis Heller pada Berbagai Habitat dan Kemampuan Bertahan Hidup Juvenil yang Dihasilkan = Fecundity Level Of Caridina Laevis Heller in a Variety of Habitats and the Survivability of the Juvenil that Generated

Abstract

Aquatic ecosystems including the lake, swamp and river areas are not spared from human life, which of course raises new issues such as the inclusion of organic waste into waters ecosystems. Caridina laevis Heller is one of the species of shrimp that live in aquatic ecosystems that is directly affected of human activities that are around water ecosystems. As for the three Habitat used in this study is the Muncul river, Rawa Pening lake and Tuntang River Rice Field area. Fecundity is the reference in this study. Fecundity is information regarding the number of juvenil produced in a single spawning. Research conducted by counting the number of eggs from each parent C. laevis taken from three different habitats and observed every 3 days, the research carried out within 14 days and Sampling was done by purposive sampling. The data obtained were analyzed with descriptive statistics, by calculating the average value and the standard deviation at the end of the study. The results showed differences in the fecundity of three different habitats. Highest number of C. laevis egg that hatch was in the Tuntang River rice field area with hatching results of 85%, followed by the Rawa Pening lake with 79% hatching results, and the Muncul river with the lowest outcome is 66% hatching.
