Abstract
The effect of molasses addiction on carbon:nitrogen ratios (C:N) on the performance of Litopenaeus vannamei shrimp during the nursery phase cultured without water exchange was investigated. The C:N ratios were evaluated in 25:1 (25M) and 15:1 (15M) proportion and a control (0M), with no carbon source addition, in a randomized experimental design with four replicates. Post-larvae (PL) with initial weight of 2.5 ± 0.5 mg were stocked in 12 tanks (800 L net volume), at the density of 6.25 PL L-1 during 42 culture days. At the end of culture, the shrimps weights on 25M (532.0 mg) and 15M (540.0 mg) treatments were higher (p < 0.05) than the 0M (428.6 mg) treatment. Shrimp survival was high in all treatments (77.9 to 90.0%), but without significant difference (p ≥ 0.05). Therefore, the 15 and 25:1 C:N ratios showed an increased growth performance of nursery phase L. vannamei post-larvae cultured without water exchange.Downloads
