In this study the optimal amount of enriching Artemia franciscana with a synbiotic combination of Pediococcus acidilactici and fructooligosaccharide (FOS( was investigated. The experiment was conducted in a completely randomized design in ten treatments: multi-level probiotics P. acidilactici (1×109, 1×108 and 1× 107 CFU per L) and multi-level enriched prebiotic FOS (1, 2 and 5) g per L of solu...

The present study investigates the effects of different routes of inulin administration as prebiotic on gut microbiota and survival rate of Indian white shrimp post-larvae. Four hundred and fifty Indian white shrimp post-larvae (PL1) were stocked in nine tanks. The tanks were assigned into three treatments: feeding with inulin-treated (110 mg L(-1)) Artemia nauplii (I-T), feeding with inulin-en...

BACKGROUND To adapt to extreme environments, the crustacean Artemia has evolved two alternative reproductive pathways. During ovoviviparous (direct) development, nauplius larvae are produced. In contrast, Artemia females release encysted diapause embryos (cysts) via the oviparous pathway. To date, the cellular mechanisms that regulate stress resistance of Artemia remain largely unknown. Ste20-l...

This study reports on the induction of oxidative stress in aerobic cell systems by Aloe barbadensis Miller (Aloe vera) juice using the salt water crustacean Artemia franciscana as a model. A consistent pattern was observed in which Artemia franciscana nauplii responded to Aloe vera juice exposure with a decrease in the overall activity of redox related enzymes. Exposure of Artemia franciscana t...

A study was carried out to determine the antibiotic resistance in bacteria isolated from Artemia nauplii and the efficiency of formaldehyde to control the bacteria associated with Artemia nauplii. The total aerobic heterotrophic bacteria of Artemia nauplii was determined on seawater nutrient agar and TCBS agar, and ranged from 3.8=10 to 8.1=10 and 9.4=10 to 4.3=10 colony Ž . forming units CFU p...

Because of limitations of production of unicellular green algae (especially in large volumes), this study aimed to culture Artemia using three sources of cheap agricultural by-products that were coupled with small amounts of unicellular algae Dunaliella salina. The results of growth and survival, biomass production, Individual wet weight, wet and ash percent, FCR and SGR and nutritional value o...

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 genus Artemia consists of several bisexual and parthenogenetic sibling species. One of them, A. franciscana, originally restricted to the New World, becomes invasive when introduced into ecosystems out of its natural range of distribution. Invasiveness is anthropically favored by the use of cryptobiotic eggs in the aquaculture and pet trade. The mechanisms of out-competition of the autochth...
