In vivo studies of digestion and nutrient assimilation in marine fish larvae
Abstract This paper describes a method for quantifying the functionality of the digestive system in fish larvae. The system described can provide data for the gut absorption, oxidation and retentionExpand

Protein content and amino acid composition of the live feed rotifer (Brachionus plicatilis): With emphasis on the water soluble fraction
Abstract Rotifers are a commonly used live feed in fish larvae cultures. Two experiments were conducted on the rotifer Brachionus plicatilis to investigate the protein and amino acid composition.Expand

Digestive physiology of marine fish larvae: Hormonal control and processing capacity for proteins, peptides and amino acids
For the majority of marine fish larvae a fully developed digestive tract, including gastric digestion, is acquired weeks to months (depending on species) after onset of exogenous feeding. Still, theExpand

The supply of amino acids during early feeding stages of marine fish larvae: a review of recent findings
In marine fish larvae, the sum of protein deposition, turnover and catabolism necessary for their rapid growth dictates a high amino acid (AA) requirement. Once the yolk is exhausted, the digestiveExpand

Protein breakdown represents a major bottleneck in nitrogen cycling in grassland soils.
Abstract Proteins represent the dominant input of organic N into most ecosystems and they also constitute the largest store of N in soil organic matter. The extracellular protease mediated breakdownExpand

Enrichment of Artemia with free methionine
Different enrichment procedures of the free amino acid FAA methionine were tested for . Artemia nauplii. A direct enrichment protocol methionine dissolved in the culture water was compared withExpand

Pre-hydrolysis improves utilisation of dietary protein in the larval teleost Atlantic halibut (Hippoglossus hippoglossus L.)
A protein preparation labelled by incorporation of [U]14C-AA was hydrolysed to various degrees and administered to a teleost fish larva (Atlantic halibut, Hippoglossus hippoglossus L.) byExpand

Metabolic budgets for lysine and glutamate in unfed herring (Clupea harengus) larvae
Abstract Fish larvae are thought to have little control of their amino acid (AA) metabolism, leading to higher AA requirements than adult fish and mammals. Therefore, it is important to know to whatExpand

In vivo incorporation of [U]-14C-amino acids: an alternative protein labelling procedure for use in examining larval digestive physiology
Abstract A radioactive soluble model protein for studies of protein digestion, absorption and amino acid (AA) metabolism in larval fish was successfully produced in Atlantic salmon by oralExpand

In vitro digestibility of water-soluble and water-insoluble protein fractions of some common fish larval feeds and feed ingredients
In vitro methods have previously been utilised for the rapid and reliable evaluation of protein digestibility in fish. In this study we used in vitro methods to compare the digestibility of variousExpand
