Signs of larval necrosis were suppressed significantly leading to higher survival rate in the early rearing period until the fourth zoeal stage when crab were treated with probiotics.
Following the nauplius phase is the zoeal phase, which includes three protozoeal (PZ1-PZ3) and three mysis (M1-M3) stages.
Larvae of both species pass through 4 zoeal stages (ZI-ZIV) and 1 glaucothoe stage (G) before they metamorphose to the first benthic crab stage (Cl) (Sato and Tanaka, 1949; Hoffman, 1968); therefore, these larval stages provide an opportunity to explore the utility of this model.
These cells migrate to a dorsolateral position in naupliar and zoeal stages, and gradually enter the genital ridge at the mysis 1 stage.
Shrimp species share the same life cycle, as described by Ryan Gandy at FWC: "Growth stages for shrimp are: egg, nauplii, zoeal, mysis, post larval, juvenile, adult.
