The survival rate of snakehead fish (Channa striata) is low. Provision natural food during the phase and growth larvae very important. Artemia a for freshwater marine which has high nutritional value, but lacks vitamin A. Enrichment techniques are needed to increase value Artemia. aim this study was compare rates, rates fed feed enriched with Snakehead were reared 16 days given A (with 1,000 IU...

Penelitian ini bertujuan untuk mengetahui pengaruh lama waktu pengkayaan HUFA (W-3 Highly Unsatured Fatty Acid) pada nauplius artemia terhadap perkembangan larva kepiting bakau (Scylla tranquebarica). Metode didesain dengan menggunakan Rancangan Acak Lengkap (RAL) 4 perlakuan masing-masing 3 kali ulangan sehingga dibutuhkan wadah sebanyak 12 unit perlakuan: A) Nauplius diperkaya selama 1 jam (K...

Bacterial diseases have been reported to be the major limiting factor in shrimp production. The use of natural products such as antimicrobials has been reported as a solution to the problem. The crude extract of a red seaweed Laurencia snyderiae obtained from the Persian Gulf was evaluated for shrimp growth performance and to determine in vivo efficacy of this seaweed in the prevention of shrim...

 Recently, the nutritional requirements of marine finfish larvae have received considerable attention, and studies have shown that docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) and arachidonic acid (ARA) affects the growth and survival of marine finfish larvae. This study investigated the effects of different Artemia enrichments containing variable amounts of DHA and EPA on the gro...

This study investigated the protective effect of poly-β-hydroxybutyrate (PHB) on Chinese mitten crab, Eriocheir sinensis, zoea larvae challenged with pathogenic Vibrio anguillarum. PHB was delivered to the crab larvae through rotifer and Artemia bioencapsulation. Zoea 3 larvae were challenged with V. anguillarum at a final concentration of 10(5) CFU mL(-1). PHB-enriched rotifers and Artemia nau...

The appearance of the pseudo-albino phenotype was investigated in developing Senegalese sole (Solea senegalensis, Kaup 1858) larvae at morphological and molecular levels. In order to induce the development of pseudo-albinos, Senegalese sole larvae were fed Artemia enriched with high levels of arachidonic acid (ARA). The development of their skin pigmentation was compared to that of a control gr...

BACKGROUND Artemia (brine shrimp) is used as feed for fish fry and shrimp in aquaculture. Two employees in a Norwegian aquaculture research farm reported having chest symptoms when working in an Artemia hatch room. AIMS To determine the presence and prevalence of Artemia sensitization at the farm and the extent of any Artemia-related respiratory and hand skin symptoms and to identify the alle...

This study determined the effect of prey DHA on larval gilthead sea bream (GSB; Sparus aurata ) photoreceptor abundance, rhodopsin expression, and growth performance. It was carried out in a twenty-eight 400 l conical tank system that stocked with 100 viable GSB eggs/l/tank. allowed testing 4 levels rotifer DHA; 0.99 (Low; L), 1.9 (Intermediate low; I-L), 3.2 high; I-H) 12.1(High; H) mg DHA/g D...

Histological observations were made in common carp larvae in order to understand the origin Ž . of the phospholipid PL requirement of fish during their young stages. Larvae were fed for 6 or 8 days after start-feeding on semi-purified diets containing peanut oil and supplemented with or Ž . Ž . without different PL fractions enriched in phosphatidylcholine PC or phosphatidylinositol PI . A grou...
