Development of Enzymes and In Vitro Digestibility during Metamorphosis and Molting of Blue Swimming Crab (Portunus pelagicus)

Table 4

Correlation coefficient (r) between different parameters studied during metamorphosis from zoea until adult P. pelagicus. Significant correlations are indicated in big bold numbers (P < 0.05).

n = 27 because interval % gain could not be calculated at 1M stage because no measurement was performed prior to this stage.
