Table 3. Growth performance and survival of Pacific white shrimp (Penaeus vannamei) post-larvae (initial mean body weight and length were 2.50 ± 0.01 mg and 0.90 ± 0.01 cm, respectively) fed Artemia nauplii enriched with different levels of poly-β-hydroxybutyrate (PHB) for 14 days
Diets | FBW1) | WG2) | LG3) | SGR4) | Survival (%) |
Con | 27.9 ± 0.09c | 1,016 ± 34.6c | 83.6 ± 2.21c | 17.2 ± 0.22c | 90.3 ± 5.69 |
PHB25 | 34.7 ± 0.19a | 1,287 ± 75.0a | 93.8 ± 1.07a | 18.8 ± 0.39a | 89.3 ± 2.31 |
PHB50 | 31.4 ± 0.04b | 1,155 ± 15.5b | 89.1 ± 0.87b | 18.1 ± 0.09b | 91.3 ± 3.79 |
p-value | 0.001 | 0.001 | 0.000 | 0.001 | 0.815 |
The Artemia nauplii was enriched with different levels of PHB by 0, 0.25 and 0.5% (designated as Con, PHB25 and PHB50, respectively).
Values (mean ± SD) are average of triplicates (n = 3). Values with different superscripts in the same column are significantly different (p < 0.05).
Final body weight (mg).
Weight gain (%) = [(Final body weight – Initial body weight) / Initial body weight] × 100.
Length gain (%) = [(Final body length – Initial body length) / Initial body length] × 100.
Specific growth rate (%) = [(Loge final body weight – Loge initial body weight) / days] × 100.
