“…TNL and TPL from the mitten crab farming sector in the reclaimed wetlands around Hongze Lake were estimated using the nutrient balance models as had been done previously for many aquatic farming practices Enell, 1990, 1994;Funge-Smith and Briggs, 1998;Teichert-Coddington et al, 2000;Wahaba et al, 2003;Guo et al, 2009;De Silva et al, 2010). As the feed types used in mitten crab farming in the reclaimed wetlands around Hongze Lake were variable (trash fish only; pellet feed + trash fish; pellet feed only), TNL and TPL for different feed types were compared.…”

“…Nutrient balance models have been used to estimate total farm nutrient loading, including total nitrogen loading (TNL) and total phosphorus loading (TPL) in many instances Enell, 1990, 1994;Funge-Smith and Briggs, 1998;Teichert-Coddington et al, 2000;Wahaba et al, 2003;Guo et al, 2009;De Silva et al, 2010).…”

“…Brazilian water quality standards for TAN and total phosphorus are ≤0.4 mg·L −1 and ≤0.12 mg·L , respectively. Various studies with monitoring of effluent and influent water quality in shrimp farms report similar results [29,38,[60][61][62][63][64]. Additionally, several researches have demonstrated effluent water from shrimp ponds typically contains elevated concentrations of dissolved nutrients compared to influent water [29,61,62,64].…”

Despite the economic importance of farmed shrimp, a number of technical, environmental, economic and social problems have been widely reported in the international literature. This paper focuses on the environmental and socio-economic impacts of semi-intensive and intensive shrimp farming in the coastal region of Northeastern Brazil and the identification of options for sustainable production. In this Region, the total area dedicated to shrimp farming is approximately 18,500 ha, of which 5750 ha are located in Ceará State. The estuary of Jaguaribe river has the largest number of shrimp farms in the state of Ceará. Currently, the industry has 64 participating farms with a total area dedicated to shrimp farming of 2411.3 ha. In 2011, the total production was 13,110 tons of shrimp with an average yield of 6.3 ton ha −1 ·year −1 in a pond area of 2071.2 ha. This industry employs 2350 people that represent 23.2% of jobs generated in the two municipalities where the Jaguaribe river estuary is inserted. Compared with other countries, Brazil has reduced its exports due to high cost inputs for shrimp farming. However, the Brazilian shrimp industry has benefited from high domestic prices, despite the decreases in international price of shrimp. In 2011, the prices for size category ranged between U$ 4.67 -6.04 for 80/100 (count of head-on shrimp), U$ 4.95 -6.60 for 70/80 and U$ 5.85 -8.10 for 50/60. The major environmental impacts in this industry have focused on the water pollution and loss of mangroves. However, no change in parameters of water quality was observed during the period 2010-2012, indicating that this estuary has some capacity to process pond-derived nutrients while only 3.7 ha of mangrove forests were used to shrimp pond. The results of this investigation demonstrate that Brazilian shrimp industry requires improved management and development policy for a sustainable growth.

Abstract. This study was conducted to characterize the native soil at shrimp Gher and agricultural land in Khulna, Bangladesh, because at present this is a growing concern that the salinity is increasing at an alarming rate. Eight locations were selected and among them five Ghers from south part of Dumuria which is about 60 km away from KUET campus, Khulna, Bangladesh. In the laboratory, various parameters such as salinity, organic content, chloride, pH, alkalinity, conductivity and moisture content were determined by following standard methods. The chloride and alkalinity were determined manually and pH, conductivity and salinity were determined by digital meter. The organic and moisture content both were highest at 30 cm depth for both the cases of shrimp Gher and agricultural land. Chloride was highest at 15 cm depth for both the cases shrimp Gher and agricultural land. Alkalinity was highest at 30 cm depth for shrimp Gher, however, the lowest was for agricultural land. It is concluded that the salinity and organic content vary with depth, age and soil condition.
