Effect of higher salinities on growth and survival of pacific white shrimp, Litopenaeus vannamei (Boone, 1931)

Abstract

Abstract:The growth and survival of Litopenaeus vannamei post larvae was measured in controlled different salinities condition 35ppt (T1), 40ppt (T2), 45ppt (T3) and 50ppt (T4) were maintained. Group of Shrimp post larvae (weight 0.032 g ± 0.002) were stocked at a density of 35 nos. /aquarium in above salinity ranges. Animals were fed with commercial feed (35% Crude Protein) @ 5% of body weight four times a day. The results indicate that higher SGR was observed in T2 (1.99±0.08) followed by T1 (1.75±0.07), T3 (1.54±0.06) and T4 (1.49±0.17). Highest survival (100 %) was recorded in T1 followed by T2 (96.42%), T3 (94.99%) and T4 (74.21%). From the results of the present study it could be seen that higher salinity significantly reduced the growth and survival of L. vannamei but will also open study area of physiological adaption of animal at higher saline water in performance of organisms.

Performance of a photo-heterotrophic, hypersaline system for intensive cultivation of white leg shrimp (Litopenaeus vannamei) with minimal water replacement in lined ponds using a stochastic approach

“…For systems with salinities slightly above the optimum, L. vannamei shows significant adaptation capabilities. Ayaz, Sumara, Vadher and Ishakani () reported good survival rates (100%–94.99%) and relatively similar SGR values ranging from 1.54 to 1.99 in systems with hypersaline water (35–45 g/L) in L. vannamei postlarvae reared 62 days. Robertson, Lawrence and Castille () reported that L. vannamei juvenile (5.3 g) reared 42 days achieved 17.5 ± 0.3 g at 46 g/L with a survival of 87%.…”

Dampak Perubahan Iklim Terhadap Budidaya Udang Vaname Di Pesisir Kabupaten Banyuwangi, Jawa Timur

“…Sejak awal era industri, penyerapan CO2 oleh laut mengakibatkan meningkatnya pengasaman air laut dan suhu Cheung et al, (2016) Dalam hal ini perubahan iklim mampu memberikan efek perubahan pada suhu, pH air laut, dan salinitas. Suhu dan salinitas dianggap sebagai faktor signifikan dalam akuakultur (Ayaz et al, 2015;Pradhan et al, 2021). Perubahan suhu rata-rata dan curah hujan rata-rata mendorong perubahan iklim pada budidaya udang.…”
