Survival of larvae of mud crab, Scylla serrata (Forsskal, 1775) is a persistent issue in the field of induced breeding of the species. A preliminary study was conducted on feeding regimes of laboratory reared larvae and juveniles of S. serrata. The results showed that the survival of the larvae fed with green water alone or green water with plankton and feed was not significantly different from...

King crab larval culture has expanded from small-scale research to hatchery and stock enhancement feasibility studies in Alaska. The goal of this project was to improve red king crab (Paralithodes camtschaticus) larval survival in culture by assessing diets and water sources in two separate experiments. Diet treatments included (1) newly hatched Artemia nauplii, and (2) newly hatched Artemia na...

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...

Effects of using n-3 HUFA-enriched Artemia and non-enriched Artemia as the starter food for growth and survival of rainbow trout larvae compared to commercial concentrated food were investigated in this study. The larvae with average weight of 92.9 mg were fed for 20 days with four food treatments included of commercial concentrated food, newly hatched Artemia, enriched Artemia, and mixture of ...

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, ...
