Copepods enhance nutritional status, growth and development in Atlantic cod (Gadus morhua L.) larvae - can we identify the underlying factors?

The current commercial production protocols for Atlantic cod depend on enriched rotifers and Artemia during first-feeding, but development and growth remain inferior to fish fed natural zooplankton. Two experiments were conducted in order to identify the underlying factors for this phenomenon

Increasing the levels of the essential trace elements Se, Zn, Cu and Mn in rotifers (Brachionus plicatilis) used as live feed

Levels of Mn, Cu, Zn, Se and iodine found in rotifers are low and may be insufficient to meet larval fish requirements. This study investigates increasing the concentration of Mn, Cu, Zn, Se and iodine simultaneously in rotifers (Brachionus plicatilis) in both short term enrichments (3h) or during batch cultures (6 days), using either organically bound or inorganic mineral sources.

Evaluation of the Biochemical Composition of Four Marine Algae and Its Nutritional Value for Brine Shrimp

Abstract: Microalgae are utilized in aquaculture as a live feed for the crustaceans, ablone, zooplanktons, etc. The present study examined the nutritional status of Artemia sp. nauplii enriched with four different algal sources namely Chaetoceros calcitrans, Skeletonema coastaum, Duniella salina & D. bardawil and also the amount of beta-carotene assimilated when enriched with the two green algae. Artemia sp. nauplii enriched with D. salina showed high amounts of protein and carbohydrate, whereas Artemia sp. fed with Chaetoceros calcitrans showed high amounts of lipid. The protein profile of Artemia sp. enriched with different algal sources  did not show prominent differences in the polypeptide bands. However, high amount of beta-carotene was assimilated in Artemia sp. nauplii when enriched with D. salina. Hence this study showed that the microalgae D. salina can be used as a potential feed to improve the nutritional status of Artemia sp. nauplii.

A new method to increase and maintain the concentration of selenium in rotifers (Brachionus spp).

Copepod fed fish larvae have higher growth rates and survival than rotifer fed larvae, possibly because of the less investigated mineral differences that exist between rotifers and copepods. n this study, the enrichment and retention of Se in rotifers fed Se enriched yeast were investigated

Development of lipid microbeads for delivery of lipid and water-soluble materials to Artemia

Lipid spray beads (LSB) containing high concentrations of phospholipids were produced in order to improve their dispersion in both fresh and saltwater. The beads were developed to deliver both fat-soluble and water-soluble micronutrients to Artemia and other suspension feeders

Evaluation of wax spray beads for delivery of low-molecular weight, water-soluble nutrients & antibiotics to Artemia

In this study, wax spray beads (WSB) consisting of bees wax, with or without a 5% w/w extract of a synthetic marine phospholipid (mPHL), were evaluated for their potential for delivery of watersoluble micronutrients and the antibiotic oxytetracycline (OTC) to Artemia. The micronutrient mix consisted of amino acids, vitamins and trace minerals and was based on the nutritional composition of copepods.

Effect of iodine enrichment of Artemia sp. on their nutritional value for larval zebrafish (Danio rerio

Dietary iodine may play an important role in the nutritional health of freshwater fish larvae. Artemia, commonly used for the culture of larval zebrafish (Danio rerio), contain low concentrations of iodine when compared with wild-caught zooplankton. Iodine concentrations of Artemia can be increased using wax spray beads (WSB) containing potassiumiodide (KI; KIWSB); however, the availability of iodine in enriched Artemia for fish larvae is currently unknown
