this study was accomplished to investigate the effect of artemia urmiana nauplii enriched with pediococcus acidilactici as probiotic on growth performance and survival rate of great sturgeon, huso huso.  artemia nauplii were enriched with p. acidilactici at a final concentration of 1010 cfu ml-1 in three time dependent treatments as 3 h (t3), 6 h (t6), 9 h (t9), and one non-enriched artemia as ...

fish oil is the important fat source in fish nutrition. high demand for fish oil and low global supply arise a need of alternative oils in fish culture. plant oils are a good candidate in this case. the aim of the present study was to compare the efficacy of fish oil and linseed oil on growth and stress resistance of tiger barb ( puntius tetrazona ) larvae. artemia nauplii were enriched by 2.5,...

One of the lessons ultimately learned from the first dramatic outbreaks of white spot syndrome virus (and other shrimp viral diseases) in the early 1990’s was that aquaculture management practices needed to be improved. Subsequent research revealed that critical factors included: broodstock sourcing, postlarva sourcing, screening techniques and strategies, diverse transmission pathways, critica...

Effect of feeding on linseed oil (LO)-enriched Artemia was investigated on growth, survival and stress resistance of tiger barb (Puntius tetrazona) larvae. Larvae were fed by LO-enriched (2.5, 5 and 7.5 %) as well as non-enriched Artemia nauplii for 14 d, followed by 14 d feeding on non-enriched Artemia. Fish fed on enriched nauplii showed significant increase in growth performance at both 14th...

This study assessed the performance of a bioluminescent bacterial assay, the ToxScreen-II Test (Photobacterium leiognathi), in comparison to the brine shrimp (Artemia franciscana) nauplii lethality assay for the detection of toxicity associated with Aloe vera leaf gel extract and the organophosphate pesticide Mevinphos. In both bioassays, clear dose-response relationships were demonstrated for ...

Artemia nauplii are the best initital food for most fish larvae. Feeder fish, nauplii, contain ingredients necessary survival of aquatic organisms during critical periods early postembryonic ontogenesis. Thus, it is important to improve biotechnology cultivation in artificial ecosystems.
 Materials and Methods. In course study, various illumination modes were used, namely, 1.5; 2.5 4 klx d...

Artemia has been widely used in aquaculture as a suitable live food. The presence of highly unsaturated fatty acids is a key factor that determines the nutritional value and marketing of Artemia for shrimp, marine larvae, sturgeon and ornamental fish industries. To determine the variation in nutritional content in cysts, decapsulated cysts and nauplii of Artemia from three different biotopes of...

The effect of essential fatty acids (EFA) and vitamin C-enriched Artemia nauplii on growth, survival, and resistance to temperature (high) stress in rainbow trout larvae reared in tanks were investigated. The larvae (average weight 120.43mg±13.5) were fed 6 times daily starting at the onset of exogenous feeding for 1 week. Triplicate groups of fish were offered one of four treatments (1) commer...

The oxidative stability and the particle size of several types of liposomes were assessed in order to characterize their behaviour when submitted to the aggressive conditions of the Artemia enrichments. Results show that all liposomes tested in this study were much more oxidatively stable than a commercial product based on fish oil emulsion. Whereas the initial thiobarbituric acid reactive subs...
