Abstract

BRICENO GARCIA, Henry Enrique et al. Feasibility of Litopenaeus vannamei (Crustaceae, Decapoda: Penaeidae) in areas from groundwater. Miranda Municipality, Zulia State, Venezuela. J.Selva Andina Anim. Sci. [online]. 2022, vol.9, n.2, pp.64-76.  Epub Oct 01, 2022. ISSN 2311-3766.  https://doi.org/10.36610/j.jsaas.2022.090200064.

The purpose of this study was to evaluate the growth, survival and productive yield of Litopenaeus vannamei at planting densities of 22 Ind m-2 in low salinity waters. The results of the culture of the white shrimp L. vannamei are presented. PL of 0.023±0.013 g were planted in 1 ha pools at densities of 22 Ind/m2. Physicochemical parameters were measured in the field (dissolved oxygen, temperature, salinity, pH, ammonium, transparency, hardness and alkalinity). The average salinity during the days of culture was 4.8 ‰. PL were acclimatized and adapted to freshwater for 72 h, in 2000 L fiber tanks before starting the culture cycle. The seeded shrimp were fed a commercial diet (35 % protein) three times a day, the ration was adjusted daily according to the monitoring results of 9 feeding troughs located in the pools. A statistic with descriptive representation was used in the study of the derivations. The crop assumed a permanence of 128 days and the following production indicators were verified: 74 % survival, 14.92 g average weight, 1.9 FCA and a yield of 1935 kg/ha/cycle. The results obtained allow us to conclude that, at the El Retorno farm in the Miranda municipality, there is the possibility of planting these crustaceans with subway water, achieving growth and survival related to lucrative yield censuses at low salinity.
