The loss rates of protein and lipids were determined for enriched Artemia franciscana starved Ž y1. at different temperatures after enrichment. Following 12-h enrichment with DHA Selco 0.2 g l Ž at 288C, the nauplii were temperature acclimated and transferred to starving condition 0–96 h; . 58C to 308C . y1 Ž . Ž The total lipid content during enrichment increased from 145 mg g dry weight DW ne...

BACKGROUND Artemia (Crustacea, Anostraca), also known as brine shrimp, are typical inhabitants of extreme environments. These hypersaline environments vary considerably in their physicochemical composition, and even their climatic conditions and elevation. Several thalassohaline (marine) environments along the Colombian Caribbean coast were surveyed in order to contribute to the knowledge of br...

although there is growing evidence that metals can be toxic to various aquatic species, there is still insufficient knowledge to integrate this information in environmental risk assessment procedures. in this study, we have investigated lethal concentration (lc50) and toxicity effects of vanadium on mortality and growth of artemia urmiana and artemia franciscana. the in 24 h of a. urmiana and a...

Feeding farmed Artemia with yeast heat shock proteins is a novel way to protect them from stress conditions during the culture.  In this study, the effect of feeding with stressed new identified Saccharomyces cerevisiae strain YG3-1 yeasts (containing induced heat shock proteins) on the survival of Artemia in stress conditions, was evaluated. For this purpose, heat shock proteins 82 (Hsps 82) o...

The use of probiotics is receiving considerable attention as an alternative approach to control microbiota in aquaculture farms, especially in hatching facilities. However, application with consistent results is hampered by insufficient information on their modes of action. To investigate whether dead bacteria (allowing investigation of their nutritional effect) or live bacteria (allowing evalu...

The populations of Artemia (or brine shrimp) from the Americas exhibit a wide variation in the amount of interphase heterochromatin. There is interest in understanding how this variation affects different parameters, from the cellular to the organismal levels. This should help to clarify the ability of this organism to tolerate brine habitats regularly subject to strong abiotic changes. In this...
