The effect of salinity on cadmium uptake and elimination by brine shrimp Artemia urmiana which lives only in Urumieh Lake, Iran, was studied for the first time. Brine Shrimp were acclimated to different salinities and exposed to the metal in solution at differing salinities and composition. Experimental salinities ranged from 50 to 125 gL and the concentrations for cadmium added to the solution...

This article presents materials on the results of an experiment enrichment Artemia salina with unicellular alga Haematococcus pluvialis to increase its nutritional value. For fry marine fish, such as mullet and kalkana, freshwater clary catfish, carp trout, supply fatty acids energy value is still insufficient. Therefore, it necessary enrich brine shrimp additional nutrients The use a component...

Trichocorixa verticalis (T. verticalis), native to North America and the Caribbean islands, is an invasive waterboatman species (Corixidae) in the southwest of the Iberian Peninsula. Previous studies in the native range have suggested that predation by T. verticalis can regulate the abundance of Anostracan and Cladoceran zooplankton in saline ecosystems, causing increases in phytoplankton throu...

The visual plankivorous feeding behaviour of the shiner perch (Cymatogaster aggregata) was investigated by means of a flow tank operated at various current speeds. Artemia salina was used as prey. In a second set of experiments, Artemia was darkened with black ink, to compare the visually mediated behaviour of C. aggregata while feeding on dark prey vs feeding on natural (i.e. semi-transparent)...

The hemoglobin molecule of the commercially important brine shrimp Artemia sp. has been used extensively as a model for the study of molecular evolution. It consists of nine globin domains joined by short linker sequences, and these domains are believed to have originated through a series of duplications from an original globin gene. In addition, in Artemia, two different polymers of hemoglobin...

Internal and external feeding on zooplankton may provide scleractinian corals with important nutrients. However, the latter process has never been properly quantified. To quantify the dynamics of zooplankton capture, digestion and release for a scleractinian coral, we performed detailed video analyses of Galaxea fascicularis feeding on Artemia nauplii. A highly dynamic process of prey capture, ...

The present investigation was focused on the effect of Bacillus megaterium enriched to Artemia nauplii and sprayed supplemented feed fed white shrimp Litopenaeus vannamei postlarvae (PL) obtain high survival growth. with different levels B. (5×107, 5×109 5×1011 cfu /mL) for a period 30 days. Similarly, probiotic PL time 15 Postlarvae cells (E2) produce better growth when compared that other con...

abstract this study was performed to compare the efficiency of 6 microalgae namely dunaliella tertiolecta, tetraselmis suecica, chlorella sp., (green algae), nannochloropsis oculata, spirolina sp.(blue-green algae) cheatocerus sp. (diatoma),  and isochrices sp. (haptophytae) on the growth, survival and reproduction efficacy in artemia urmiana in laboratory conditions. artemia cysts were harvest...
