“…Water status in aquaculture lakes will continue to degrade and be uncontrolled unless we take proper policy measures for preventive and restorative strategies to achieve the balance condition and integrity of regional aquaculture lake ecosystems (Abeysinghe et al 1996;Naigaga et al 2011). Some contaminants flowing in lakes could accumulate to a point where it threatens human health even in low quantities and causes no obvious adverse effects.…”

Due to a lack of the related data, there were no simple water indexes available for indicating water quality. Motivated by the fact that many lakes and reservoirs in Indonesia have been polluted because of aquacultural activity, this paper proposed a Water Quality Index, called the Aquaculture Water Quality Index (AWQI), and presented the development of practical tool to aid the development of aquaculture in Indonesia. Specific purposes included: (a) providing a brief summary of the assessment results of the existing WQI; (b) developing the AWQI method for applying in an aquacultural context; (c) implementing the AWQI method in Depok Area (Indonesia) as study area. An AHP method was also processed to define the weights of selected water quality parameters: DO, ammonia, pH, and fecal coliform. The AWQI had several features: (a) a low-cost water quality monitoring program that could be used by developing countries; (b) a useful tool for water resource agencies, especially for local agencies, to manage waterbodies and to raise public awareness of water pollution for its data, as its data could be easily understood and interpreted.

“…We used systematic sampling with a random starting point (Morrison et al 2008). Fifty transect lines (standard length = 300 m) were established alongside floodcontrol channels in each habitat type (25 straight-line transects were used in each PSFC and MFC smallholding).…”

“…Numerous studies have found an association between water quality and aquatic fauna diversity or abundance, although these studies have typically focused on fish and invertebrates (Inoue and Nakano 2001;Arimoro and Ikomi 2009;Silva et al 2010;Naigaga et al 2011). The physicochemical water quality characteristics of oil palm drainage channels have not previously been studied.…”

Oil palm expansion is a major driver of habitat loss in the tropics. Although a number of studies have evaluated the consequences for terrestrial biodiversity, the effects on wetland habitats and fauna are less well described. This study aims to determine the conservation value of flood-control drainage channels in oil palm smallholdings for waterbirds. We also measured the water quality (water temperature; pH; dissolved oxygen, DO; total dissolved solids, TDS; salinity; water depth; conductivity; and turbidity) and habitat characteristics (vegetation cover and channel width) to determine the relationship between waterbird species richness, water quality, and habitat characteristics. Birds were surveyed along 25 line transects within peat swamp-and mangrove-converted oil palm smallholdings. Data were collected in seven smallholdings between March and December 2013. We recorded a total of 1111 waterbirds from eight resident species. Both mangrove forest-and peat swamp-converted smallholdings had similar waterbird diversity. Waterbird species richness increased with increasing DO and decreased with water depth, temperature, and conductivity. The most parsimonious predictive model (minimum quasi Akaike information criterion = 476.48) explained 52.39 % of the variation in species richness. Our data indicate that even manmade aquatic habitats, such as flood-control channels, can be important for some waterbirds in oil palm smallholdings. However, considering the relatively small increase in waterbird species richness in channels, the most successful strategy for conserving waterbirds will require protection of intact wetlands supported by better management of drainage channels in oil palm smallholdings.

“…Dažniausiai pagal biologines bendrijas tiksliai apibrėžiami vandens ekosistemos rodikliai, priklausantys nuo aibės biotinių ir abiotinių veiksnių. Žuvys atlieka svarbų bioindikatoriaus vaidmenį valdant vandens išteklius (Naigaga et al 2011). Chovanec et al (2003) apibrėžė bioindikatoriaus sąvoką -tai organizmas ar organizmų bendrija, kuriuos tiriant gaunama pakankamai informacijos apie aplinkos kokybę.…”
