| Decapsulated <i>Artemia</i> cysts were used to study the factors which induce the superior performance of live organisms as food for fish larvae. The biochemical composition, the in vitro protein digestibility, and the total proteolytic and trypsin activities in cysts and nauplii of <i>Artemia</i> were determined at different developmental stages as a function of incubation time. Six different incubation times were studied: 1, 6, 11, 16, 21 and 25h of development, which cover cyst and early nauplii stages. The individual dry weight of <i>Artemia</i> decreased through development. The individual protein and lipid content (µg ind<sup>-1</sup> remained constant during development until the time of hatching after... |

| Among the environmental variables influencing the performance of fish larvae, the quantity and quality of food belong to the more important ones. Alterations of nutritional condition affect, apart from changing growth and survival, a number of structural and molecular parameters of the larvae. Particularly the absence of food has pronounced effects on histological features of, <i>e.g.</i> the liver and the intestine, on activities of digestive proteolytic enzymes, as well as on RNA/DNA ratios. The starvation-related changes are similar for the larvae of totally different fish species, <i>e.g. Clarias gariepinus</i>, a tropical freshwater species, the whitefish <i>Coregonus lavaretus</i>, from temperate freshwaters, or... |
