Fish: Feed & Nutrition
Feed and nutrition: Culture of live food
Manual on the production and use of live food for aquaculture
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.
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
Culture of Small Zooplankters for the Feeding of Larval Fish
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
Rotifer Production (as a First Feed Item) for Intensive Finfish Larviculture
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.
Artemia Production for Marine Larval Fish Culture
This publication describes the process of hatching Artemia cysts for use as larval food for cultured species, and the benefits of Artemia as a food source...Read more.

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.
Timothy A. 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 OneStep™, results in better nutrition, stronger rotifers, less stress and healthier larvae – with less work and mess.
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
