Morphology and ultrastructure of digestive system in pre-zoea and zoea I larvae of red king crab, Paralithodes camtschaticus (Tilesius, 1815)

Cell and Tissue Research, 2023
The digestive system structure in pre-zoea and zoea I larvae of the red king crab Paralithodes camtschaticus has been examined. During this development period, the digestive system consists of an esophagus, a stomach, a midgut (where the hepatopancreas ducts open), and a hindgut.

Zoea-2 syndrome of Penaeus vannamei in shrimp hatcheries

Aquaculture, 2017
Mortalities of Pacific white shrimp, Penaeus vannamei during zoea stages were investigated in fifteen Indian shrimp hatcheries located on the east coast of India. Popularly known as zoea-2 syndrome, is characterized by reduction in feeding rate of late zoea 1 and early zoea 2 stage larvae, impairment in metamorphosis followed by high mortalities ...

The Zoea of Eurynome aspera

Journal of the Marine Biological Association of the United Kingdom, 1924

Nervous systems in 3D: a comparison of Caridean, anomuran, and brachyuran zoea-I (Decapoda).

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2013
ABSTRACTUsing serial semi‐thin sections and digital 3D‐reconstructions we studied the nervous systems of zoea‐I larvae in three decapod species, Hippolyte inermis (Leach, 1815), Porcellana platycheles (Pennant, 1777), and Pachygrapsus marmoratus (Fabricius, 1787).

Semilunar rhythm in the zoea-release activity of the land crabs Sesarma

Oecologia, 2004
The number of the land crabs Sesarma which released zoeae in a river was counted and recorded for 2 years. The number of crabs releasing zoeae reached a maximum at around every syzygy and decreased to a minimum at around every half moon, showing a semilunar rhythm (Fig. 2).
