Production performance of white shrimp Litopenaeus vannamei with super-intensive culture on different rearing densities

Abstract

This research aimed to evaluate the production performance of white shrimp Litopenaeus vannamei with super-intensive culture on different rearing densities. The research was conducted at PT. Dewi Laut Aquaculture, Cikelet, Garut, West Java. As many of 8 ponds were used and divided into 2 groups based on the stock density of shrimp, 550 ind/m2 and 650 ind/m2, and reared for 99 days. The results showed that super-intensive shrimp culture at the density of 550–650 ind/m2 potentially produced shrimp with average body weight ranged from 15.91–19.31 g, survival rate 62.67–87.95%, growth 0.16 to 0.20 g/day, FCR 1.35–1.66, and productivity reach 5.55–9.19 kg/m2. There were no significant differences between the two stocking densities in body weight, growth, and feed conversion performance, while ponds with higher rearing density had better survival and productivity than ponds with lower rearing density. L. vannamei cultured at a density of 650 ind/m2 produces the best performance and most feasible to be applied in super-intensive white shrimp cultivation.

 ABSTRAK
 Penelitian ini bertujuan untuk mengevaluasi kinerja produksi udang vaname pada sistem super- intensif dengan padat penebaran berbeda. Penelitian dilaksanakan di tambak PT. Dewi Laut Aquaculture, Cikelet, Garut, Jawa Barat, menggunakan 8 petak tambak. Tambak dibagi menjadi 2 kelompok, masing-masing 4 petak tambak dengan padat tebar udang 550 ekor/m2 dan 4 petak tambak lainnya dengan padat tebar 650 ekor/m2 dengan masa pemeliharaan 99 hari. Hasil penelitian menunjukkan bahwa budidaya udang vaname pada sistem super-intensif dengan padat tebar 550–650 ekor/m2 dapat menghasilkan udang dengan bobot rata-rata berkisar antara 15.91–19.31 g, sintasan 62.67–87.95%, pertumbuhan 0.16–0.20 g/hari, konversi pakan (FCR) 1.35–1.66, dan produktivitas mencapai 5.55–9.19 kg/m2. Tidak ada perbedaan nyata antara kedua padat penebaran pada kinerja bobot, pertumbuhan harian, dan FCR; sementara tambak dengan kepadatan tinggi memiliki nilai sintasan dan produktivitas yang lebih tinggi dari tambak dengan kepadatan rendah. Padat penebaran 650 ekor/m2 menghasilkan kinerja produksi terbaik dan paling layak untuk diaplikasikan dalam budidaya udang vaname super-intensif.

Growth of Vannamei Shrimp (Litopenaeus vannamei) in Intensive Cultivation Systems

“…Growth parameters calculated include survival rate, average weight, daily growth and feed consumption ratio. The calculation formula Rakhmanda et al (2021)…”

“…A decrease in temperature outside the optimal range can also reduce DO in water, thereby increasing salinity conditions which can trigger a stress response in aquatic organisms so that their growth decreases and affects cultivation productivity (Fakhriyah et al, 2022). White vaname shrimp can tolerate salinity in the range of 4 -32 ppt (Rakhmanda et al, 2021). According to Harlina et al (2022), salinity is related to the osmotic pressure of water which influences osmoregulation and shrimp growth.…”

Feed Efficiency and Growth of Vannamei Shrimp (Litopenaeus vaname) with Commercial Feeding

“…Availability of the right feed, both in quality and quantity is an absolute requirement to support shrimp growth, which in turn can increase production. Feeding in excessive amounts can increase production costs and waste and cause excess feed residue which will result in a decrease in water quality thereby affecting the growth and survival of shrimp 4 .…”
