International study on &lt;i&gt;Artemia&lt;/i&gt; : 17. Energy consumption in cysts and early larval stages of various geographical strains of &lt;i&gt;Artemia&lt;/i&gt;

Variations in dry weight, caloric content and ash content during cyst hatching and early larval development have been studied for various geographical strains of &lt;i&gt;Artemia&lt;/i&gt; . In general, decapsulated cysts contain 30 to 40% more energy than freshly hatched nauplii; for Chaplin Lake and Buenos Aires &lt;i&gt;Artemia&lt;/i&gt; this difference amounts to 57%. Ash contents increase as decapsulated cysts hatch into instar I and molt into instar II-III nauplii. Over a 24h larval developmental period individual dry weights and energy content of the nauplii decrease with 16-34% and 22-37% respectively.A small but significant correlation exists between the survival rate of starved nauplii and either the energy content of instar I and instar II-III...

Larval development of Austinixa bragantina (Crustacea: Brachyura: Pinnotheridae) reared in the laboratory
Provedor de dados: 103
Autores: Lima,Jô de Farias.
The zoeal and megalopal stages of Austinixa bragantina Coelho, 2005, a small pinnotherid crab found in association with ghost shrimps Callichirus major (Say, 1818) and Lepidophthalmus siriboia Felder &amp;amp; Rodrigues, 1993 in the northeastern region of the state of Pará, Brazil, were reared in the laboratory from hatching to the megalopal stage. The duration of the larval period from hatching to megalopa was 28 days and the mean of duration for each larval stage was 6, 5, 5, 6, and 6 days, respectively. In the present study, the zoeal and megalopal stages are described and illustrated in detail.
