Effects of reduced salinity on the biochemical composition (lipid, protein) of zoea 1 decapod crustacean larvae.
After hatching, the female crab was removed from the incubation tank, using a scoop net, and the aeration was turned off in order to settle down any debris to the bottom of the incubation tank, while the energetic zoea remained active at the surface.
The survival rates at each of the five larval stages such as zoea 1 (Z1), zoea 2 (Z2), zoea 3 (Z3), zoea 4 (Z4) and megalopa (M) (identified as per Shinkarenko [18]) were calculated by daily random sampling (mortality due to any reason other than temperature or salinity variation is assumed to be the same in all the replicates of the values tested under each parameter).
The stage-1 zoea (hatching stage) will not undergo its initial molt to the stage-2 (first feeding) zoea until it reaches saline waters (Dugan et al.
The eggs hatch into larvae called zoea that spend about a month in the ocean as tiny swimming plankton.
Zoea of the dominant local blue crab (Callinectes bellicosus) are most abundant in the BMLC during August, when the vast numerical majority (89%) have been observed (Sanchez-Ortiz and Gomez-Gutierrez 1992).
Length of time from zoea I to megalopa varied from 20 to 31 days.
After the first larval transformation, the mysid and zoea stages have to be fed with live Artemia franciscana nauplii.
We also found a distinct diurnal drift pattern for shrimp zoea with peak drift occurring near midnight; however, migration was too low to determine any diurnal patterns.
