“…Shrimp culture technology should not only focus on increasing productivity and product quality but should also be able to reduce negative social and environmental impacts [18,99]. Waste originating from intensive ponds consists of feed that is wasted during culture and feed that is not digested by shrimp that is wasted through feces and excretion of shrimp during rearing.…”

“…Waste originating from intensive ponds consists of feed that is wasted during culture and feed that is not digested by shrimp that is wasted through feces and excretion of shrimp during rearing. Aquaculture business is a major contributor to the increase in waste and toxic compounds in the form of ammonia as the main nitrogen waste [18,46]. About 20 -30% of the total N and P content in the feed will be wasted into the aquatic environment [100].…”

“…One of the causes of the decline in the environmental quality of coastal waters is the discharge of aquaculture waste during operations which contains high concentrations of organic matter and nutrients. This condition is a consequence of the input of pond production facilities in aquaculture, resulting in residual feed and faeces dissolved into the surrounding waters [18,133,134]. In commercial aquaculture, 30% of the total feed given is not consumed by fish/shrimp, and about 25 -30% of the feed consumed will be excreted [135].…”

“…Efforts to produce more shrimp in shrimp culture with intensive technology, pond farmers can increase production to meet the needs of shrimp demand without putting pressure and burden on the contribution of waste to natural resources [12,15]. On the other hand, the intensification of whiteleg shrimp culture ponds can negatively impact polluting waste in the aquatic environment in coastal areas [8,11,[16][17][18]. Waste from whiteleg shrimp ponds can come from shrimp feed and faeces.…”

“…Feeds from intensive technology have been reported to be a significant source of waste in aquaculture systems [22,23]. The results of previous studies have revealed that most of the input of N and P into shrimp ponds as feed is not converted into shrimp biomass but is wasted into the environment [9,10,18,24,25]. High concentrations of nutrient waste discharged from shrimp ponds can cause eutrophication in coastal areas receiving waste [9,10,16].…”

Bulukumba Regency, South Sulawesi, Indonesia is one of the centres for whiteleg shrimp, Litopenaeus vannamei production that applies intensive technology. However, no information has been obtained regarding the characteristics and status of water quality in coastal areas with environmentally friendly concepts and the potential to receive a waste load. The study aimed to determine the performance of whiteleg shrimp culture in relation to temporal and spatial aspects and characteristic and water quality status. Measurement and sampling of water were carried out before stocking/initial of culture whiteleg shrimp (rainy season) and end of culture/after harvesting of whiteleg shrimp (dry season) at two locations in the coastal area of Bulukumba Regency, namely Bonto Bahari Subdistrict (BB) and Gantarang Subdistrict (GT). Variables measured and analyzed included temperature, salinity, pH, dissolved oxygen, nitrate, nitrite, ammonia, phosphate, total suspended solids, and total organic matter. Data analysis with descriptive statistics, multivariate statistics, and non-parametric statistics. The Storet (Storage and Retrieval) method was used to determine the water quality status. The results showed that the culture of whiteleg shrimp was technology-intensive with a stocking density of 110 - 220 ind/m2 with productivity between 13.9 - 44.4 tons/ha/cycle. The predicted waste load of N is 28.00 tons/cycle and P reaches 6.61 tons/cycle. Another result was that changes in water quality status during the rainy season were classified as moderately polluted at the BB location and complying quality standards at the GT location, while in the dry season, both locations were categorized as heavily polluted. Variables of water quality that caused the decrease in water quality status in both locations (BB and GT) were observed to increase salinity, nitrate concentration, and ammonia concentration. However, there was a decrease in dissolved oxygen concentration in the dry season.
