Culture Practices of Litopenaeus vannamei in Fresh Water Grow-Out Ponds
Background/Objectives: Shrimp farming has been made an impressive growth in many developing countries especially in Asian countries. This activity is paved way to prominent economic growth and social importance.
Methods/Statistical analysis: The present study was undertaken for shrimp culture during August 2015 – November 2015 from fresh water aquaculture farm. Water samples were collected from culture ponds during the study period to analyze various physico-chemical parameters. The L.vannameiseeds (post larval stage 14) that had been acclimatized to the oppt salinity and it were confirmed disease free, transport with maintained optimum condition and reached to the ponds. The seeds were properly stocked in the culture ponds.
Findings: The water temperature values varied from 24°C and 28°C.Ranges of salinity 0.5 - 2.5 ppt were recorded. DO (dissolved oxygen) values varied from 4 and 7.1ml/l. The maximum pH values of 8.0 was recorded during the month of November 2015 and minimum of 7.3 was observed during August 2015. The maximum of feed provision 3.635tn was recorded in P3 (pond 3) and minimum of 3.145 was recorded at P1 (pond 1). The maximum ABW 25.3g was recorded in P3 and minimum of 24.5 was recorded at P1. The maximum biomass 2.340tn was recorded in P3 and minimum of 2.058tn was recorded at P2.
Application/Improvements: Shrimp culture has been increasing recent years in Indian Subcontinent. Liberalization of economy, high profitability and good international market are the factors, this has been given new impetus for shrimp culture boom in India. Hence, the present has been carried out the culture activity of L. vannamei in fresh water environment. This will be motivated and enhanced the culture practices.
