Resumo: | 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 nauplii or the proportional energy consumption during metabolism from decapsulated cysts to instar II-III nauplii. The potential impact of these results on the use of &lt;i&gt;Artemia&lt;/i&gt; in aquaculture hatcheries is discussed.
