Effect of molting hormone, 20-hydroxyecdysone on blue swimming crab, Portunus pelagicus (Linnaeus, 1758) larval rearing

Blue swimming crab, Portunus pelagicus commercial aquaculture production has not been established since the past few years and seeds production is problematic and unstable. The survival rate is low and mass mortality often occurs especially in larval stages. A study on the effects of molting hormone...
