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
Upon completion of the rotifer stage, the most commonly used live feed prior to conversion of the larva to a dry diet is Artemia. the larviculture production system

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
This publication concentrates on the culture and feeding of rotifers, but includes information on less used zooplankton such as cladocerans (water fleas), copepods and tintinnid ciliates
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
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
The purpose of this manual is to describe what fatty acids are, their nutritional importance, and ways they can be used to enrich live feeds. This manual focuses on the use of and enrichment of Artemia
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.
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.
A high quality algae diet accelerates growth and shortens the time to larval settlement or spat set in many bivalve hatcheries...Read More.
This new book provides a complete overview of all aspects involved in the production and utilization of microalgae resources at a commercial scale.
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.
The consortium has launched a new website which will include publications and training courses on good practices.
The manual describes the major production techniques currently employed for the cultivation of the major types of live food commonly used in larviculture, as well as their application potential in terms of their nutritional and physical properties and feeding methods.
Timothy Allen Reed, president, CEO and head of research and development, and Eric C. Henry, Ph.D., research scientist at Reed Mariculture Inc. discuss how feed and enrichment of rotifers in one step with their new product, RotiGrow OneStepTM, results in better nutrition, stronger rotifers, less stress and healthier larvae, with less work and mess.
This paper focuses on the monoculture of microalgae under clearly defined environmental conditions and production protocols...Read more.
Live feeds are an integral component in the cultivation of most marine finfish species during larval stages. The first live feed that has demonstrated acceptability for most marine species, and which can typically be raised on a commercial scale, is the rotifer Brachionous spp...Read more.
