this research aimed to assess factors of water quality in ponds l. vannamei in site of bushehr helle and provide solutions to improve water quality shrimp l. vannamei were conducted in this area, during the period of 120 days. this studies was conducted across the 7- hectare pond with a density of 22 shrimp per square meter in breeding site of bushehr helle in 2013. from parameters of water oxy...

a case study was carried out to see the impacts of shrimp culture on the surface (pond) and ground water (tube-well) quality in three coastal sub-districts of bagherhat sadar, rampal and morrelganj of bangladesh. the people of rampal (100%), morrelgonj (87.5%) and bagherhat (75.5%) expressed that salinity of both surface and ground water increased after shrimp culture, and water becomes more tu...

Oliveira, V. P.; Freire, F. A. M. & Soriano, E. M. 2012. Influence of depth on the growth of the seaweed Gracilaria birdiae (Rhodophyta) in a shrimp pond. Braz. J. Aquat. Sci. Technol. 16(X): 33-39. eISSN 1983-9057. This study evaluates the influence of depth and environmental parameters on the development of Gracilaria birdiae Plastino & Oliveira (Gracilariaceae) in an organic shrimp pond. The...

Temperature is one of the most principle factors affects aquaculture system. It can cause stress and mortality or superior environment for growth and reproduction. This paper presents the control of pond water temperature using artificial intelligence technique. The water temperature is very important parameter for shrimp growth. The required temperature for optimal growth is 34C, if temperatur...

Pacific whiteleg shrimp Litopenaeus vannamei (Boone, 1931) cultured worldwide with developments and revolutions in culture ponds like spread polyethylene liner over earthen ponds. The length-weight relationships shrimp, was evaluated (PE) lined from Bhimpore village of Surat district (Gujarat). For this purpose, 500 specimens pond were collected during 2021 their length weight recorded as per t...

Evaporation basins (or ponds) are the most commonly used facilities for disposal of selenium-laden saline agricultural drainage in the closed hydrologic basin portion of the San Joaquin Valley, California. However concerns remain for potential risk from selenium (Se) toxicity to water fowl in these evaporation basins. In this study, we examined the chemical status of Se in both waters and sedim...

The performance of the Paci¢c white shrimp Litopenaeus vannamei (Boone) under various stocking strategies was evaluated in earthen ponds ¢lled with freshwater amended with major ions. Six 0.1-ha earthen ponds located in Pine Blu¡, AR, USA, were ¢lled with freshwater in 2003 and 2004, and potassium magnesium sulphate added to provide 50mgK L 1 and stock salt added to provide 0.5 g L 1 salinity. ...

Aquaculture has become one of the livelihoods for people who live near shore. Fish, shrimp, and crabs are cultivated using traditional method, which still involves workers checking vanammei shrimp pond's condition directly on site. We present a new technology fish farming by automation. An automation system is needed to control remotely so that farmers can easily access Water temperatu...

A mathematical model is used to investigate the role of sedimentation and remineralization in the sediment on nitrogen (N) dynamics in intensive shrimp culture ponds. The model describes the key processes involved in N cycling that underpin the dynamics of total ammoniacal N (TAN), nitrate/ nitrite (NOX) and chlorophyll a (CHL) concentrations and the sediment N pool. These parameters may, in hi...

The feasibility of totally replacing the fishmeal component of marine shrimp (Litopenaeus vannamei) diets was examined both in the laboratory setting and during a full–scale commercial trial. Animals were fed either a traditional fishmeal–based diet or one in which complete replacement of fishmeal, on a per protein basis, was manufactured using a yeast–based product, NuPro®. Laboratory studies ...
