Activity of digestive enzymes in yolk-sac larvae of Atlantic halibut (Hippoglossus hippoglossus): indication of readiness for first feeding
The problem of determining when larvae should be offered food is particularly difficult in a species such as Atlantic halibut that has a long yolk-sac period (280–320 degree days, dd). In order toExpand

Nutrient composition and metamorphosis success of Atlantic halibut (Hippoglossus hippoglossus, L.) larvae fed natural zooplankton or Artemia
Atlantic halibut larvae were fed docosohexanoic acid- (DHA) selco enriched Artemia (RH-cysts) or wild zooplankton in duplicate tanks from first-feeding and 60 days onward. The zooplankton wereExpand

RNA, DNA and protein during early development in feeding and starved cod (Gadus morhua L.) larvae
Abstract Quantitative changes in DNA, RNA and soluble protein were studied in the early stages of developing cod larvae. Similar macromolecular metabolism was observed in larvae reared underExpand

Iodine enrichment of Artemia and enhanced levels of iodine in Atlantic halibut larvae (Hippoglossus hippoglossus L.) fed the enriched Artemia
Flatfish metamorphosis is initiated by the actions of thyroid hormones (TH) and iodine is an essential part of these hormones. Hence, an iodine deficiency may lead to insufficient levels of TH andExpand

An optimum level of vitamin A supplements for Atlantic halibut (Hippoglossus hippoglossus L.) juveniles
Six diets with different levels of retinyl acetate were fed in triplicate to Atlantic halibut larvae for 13 weeks. The dietary levels used were 0, 0.25, 0.75 (National Research Council (NRC)Expand

The impact of nutrition on metamorphosis in Atlantic halibut (Hippoglossus hippoglossus L.)
Fatty acids, vitamin A and thyroid hormone have all been shown to affect development of flatfish larvae and they are ligands to nuclear receptors that participate in the control of development. OurExpand

Marine raw material choice, quality and weaning performance of Ballan wrasse (Labrus bergylta) larvae
Previous results show that weaning success of Ballan wrasse larvae greatly depends on the quality of the dietary marine raw materials. In the present study, six moist or agglomerated experimentalExpand

Culture parameters, growth and mortality of halibut (Hippoglossus hippoglossus L.) yolk sac larvae in upwelling incubators
Abstract Halibut yolk sac larvae were raised in upwelling incubators with different rates of continuous flow. Rate of mortality increased with increasing rate of flow, but in a stagnant incubatorExpand

A comparison of retinol, retinal and retinyl ester concentrations in larvae of Atlantic halibut (Hippoglossus hippoglossus L.) fed Artemia or zooplankton
Atlantic halibut (Hippoglossus hippoglossus L.) larvae were fed enriched Artemia or zooplankton in duplicate tanks from 0 to 60 days after first-feeding. Both diets and the larvae were analysed forExpand

Large-scale rearing of Atlantic halibut, Hippoglossus hippoglossus L., yolk sac larvae: effects of flow rate on growth, survival and accumulation of bacteria
The role of flow rate in large-volume production units (2800 L silos) for Atlantic halibut, Hippoglossus hippoglossus L., larvae was studied. Correlations between flow rate, bacterial numbers (aExpand
