Endogenous water pollution and excessive nitrogen in ponds have always been prominent problems threatening aquaculture. To solve this problem, a 70-day indoor simulation experiment was conducted. The snail Bellamya purificata stocked at four different densities: 0, 15, 30, 60 individuals/tank, represented as CON (control), LD (low density), MD (medium HD (high respectively, to investigate the e...

Indirect interactions among community members impact on organisms. The effects of two snails, banded pond snail, Bellamya bengalensis (Lamarck), and Red-rimmed melania, Melanoides tuberculata (Müller), and tadpoles of Asian common toad, Duttaphrynus melanostictus (Schneider), on nonbiting midge larvae, Chironomus striatipennis Kieffer, were observed in experimental microcosm. Decrease in tube n...

There is a global increase in urbanization, which contributes to the loss and fragmentation of urban wetland pond habitats. Urban ponds have an important role ecology areas, as they provide essential habitats for aquatic species. The objective this study demonstrate ecological engineering approaches restoring biological communities ecosystem, can be used achieve water purification such ecosyste...
