Performance and land characteristics of brackishwater pond to support sustainability of Pacific white shrimp (Litopenaeus vannamei) culture intensive technology.

Intensive technology Pacific white shrimp (Litopenaeus vannamei) culture has been applied in Bulukumba Regency, South Sulawesi Province, but information on the performance of Pacific white shrimp culture and the land characteristics or environment of the pond has not yet been obtained. The research purposes are to find out the performance and the land characteristics or environment of Pacific white shrimp culture intensive technology to serve as a basis for determining the culture development. Five transects perpendicular to the shoreline and three transects parallel to the coastline, or 15 water sample stations, were identified in the field. Other data was obtained from the extraction of Sentinel-2 and SPOT (Satellite pour l'Observation de la Terre) satellite imagery 7. The size of intensive technology Pacific white shrimp culture ponds in Bulukumba Regency ranges from 1600 to 5000 m which is stocked with fry with a stocking density of 100-300 ind./m which can produce 12.0-50.0 tons/ha/cycle after rearing for 100-142 days of culture with a food conversion ratio of 1.2:1-2.0:1. The land characteristics of intensive technology Pacific white shrimp culture ponds in Bulukumba Regency are characterized by elevation from 10.0 to 20.0 m above sea level, wavy topography, tidal range between 1.35 and 1.70 m, dominated by Latosol or Cambisol and Alfisol or Mediterranean soil great groups, the quality of the source water can generally support Pacific white shrimp culture, and the annual rainfall is from 1341 to 1763 mm and it is not built on former mangrove land. It is recommended that existing Pacific white shrimp culture ponds increase the capacity and capability of their wastewater treatment plant ponds and implement better water management and feed management so that the quality of wastewater from intensive technology Pacific white shrimp culture ponds can also be better so that productivity can be increased and sustainable.
