Adaptation of Bathynellacea (Crustacea, Syncarida) to Life in the Interstitial (“Zoea Theory”)
Internationale Revue der gesamten Hydrobiologie und Hydrographie, 1981AbstractThis study aims at demonstrating that the Bathynellacea arose by neoteny from a zoea‐like ancestor (“Zoea Theory”). Bathynellacea basically have a larval morphology. Their post‐embryonic development passes through phases which are directly comparable with some in the development of primitive Eucarida.

To improve availability of penaeid seedstock during periods of high demand, experiments were conducted to determine the feasibility of stockpiling embryos by freezing them. Embryos were screened for developmental stage; cryoprotectants, chilling effects, and freezing regimens were likewise evaluated.

The colour change of the zoea of the shrimp, crangon crangon L.
Experientia, 1953Das Chromatophorensystem der Zoea-Larve der SandgarneleCrangon crangon L. ist einfacher ausgebildet als das der erwachsenen Garnele und zeigt auch ein anderes Verhalten Lichtreizen gegenuber. Dieses sogenannte primare Chromatophorensystem reagiert nur auf einfallendes Licht, und zwar durch Pigmentdispersion, wobei kurzwelliges Licht mehr aktiv ist. Das

Nucleus patterns of zoea I larvae (Crustacea: Decapoda) in the context of taxonomy
Zootaxa, 2010Using DAPI as a nucleus marker, we studied zoeas of 6 decapods (Palaemon adspersus Rathke, 1837; Palaemon elegans Rathke, 1837; Porcellana platycheles (Pennant, 1777); Pisidia longicornis (Linnaeus, 1767); Xantho hydrophilus (Herbst, 1780) Xantho pilipes A.

Semi Automated Rack Collection of Brachyuran Crab Zoea in a Spawner Unit
Arab Gulf Journal of Scientific Research, 2014The design and operation of a small research scale berried female rearing system for the collection of brachyuran first formed zoea in high quality and quantity are described in the present paper. The envisaged novel zoea collection system discloses a tray shelf system with an aqua terrarium on the upper shelf with provision of an accessible dry zone ...
