CASE STUDY: VANNAMEI SHRIMP (Litopenaeus vannamei) GROW-OUT FARMING AT ANTONIUS HDPE POND, MUARA JAMBU VILLAGE, LINGGO SARI BAGANTI SUB-DISTRICT, PESISIR SELATAN REGENCY

Abstract

HDPE ponds are a type of aquaculture pond (such as for shrimp or fish) in which the base is lined with an HDPE (High Density Polyethylene) geomembrane, a kind of plastic that is highly durable and resistant to chemicals, UV rays, and mechanical damage. HDPE ponds are also more environmentally friendly compared to conventional earthen ponds because they reduce the risk of soil and surrounding water contamination from aquaculture waste. This study aims to examine the effectiveness of the HDPE pond system in the grow-out culture of whiteleg shrimp (Litopenaeus vannamei) in Pesisir Selatan Regency, West Sumatra. This research employed a descriptive, quantitative case study approach spanning three cultural cycles. The observed parameters included shrimp growth, survival rate (SR), feed conversion ratio (FCR), water quality, and business feasibility analysis. The best results were obtained in the third cycle, with an SR of 95%, FCR of 1.4, and production of 3,500 kg. The HDPE pond system proved to increase production efficiency and support sustainable aquaculture. The best culture performance occurred in the third cycle because rainfall was very low during this period and environmental conditions were well controlled.
