Effect of Extramin on growth enhancement of white leg shrimp Litopenaeus vannamei (Boone, 1931) in low saline semi-intensive pond culture system


Author(s): Edward Gnana Jothi George, Godfred Ponraj Jeyaraj and Veera Ravi Arumugham

Abstract: .The present work emphasizes the impact of the commercial mineral product, Extramin on achieving higher productivity in low saline (0 to 10 psu) Litopenaeus vannamei culture. Water quality parameters like salinity, pH, temperature, dissolved oxygen, total hardness, nitrate, transparency, alkalinity, and phytoplankton population dynamics were monitored in control and test ponds treated with Extramin. In addition, product response parameters like the effect of Extramin on molting, white muscles, muscular cramps, arising due to mineral deficiency and impact on survival and food conversion ratio (FCR) were also assessed. Affected shrimp ponds achieved 100% recovery upon administration of Extramin. Test ponds treated with Extramin has developed stable and proper bloom with good population of planktons ranging from 254-359×104 cells ml-1, whereas, in control ponds 214-279×104 cells ml-1 with frequent crash were observed. Overall, the ionic composition and stoichiometry were well balanced in Extramin treated ponds for shrimp growth favouring higher productivity.
