Organic monogastric agriculture is challenged because of a limited availability regional and organic protein-rich ingredients to fulfill the amino acid requirements. The development novel feed therefore essential. use starfish (Asterias rubens), mussel (Mytilus edilus), insect, green brown seaweed, forage crop extracts exhibits different approaches increase protein in sustainable manner through...

Following a meal, series of physiological changes occurs in fish as they digest, absorb and assimilate ingested nutrients. This study aims to assess post-prandial free amino acid (FAA) activity gilthead sea bream consuming partial marine protein (fishmeal) replacement. Sea were fed diets where 16 27% the fishmeal was replaced by plant protein. The essential (EAA) composition white muscle, liver...

Life cycle assessment (LCA) was applied to evaluate black soldier fly production using different diets, including typical Belgian agro-residues (Brussels sprout stems, endive roots and solid fraction pig manure). The LCA compared insect-based feed with soybean meal fishmeal, composting through insects versus conventional treatments. Underlying data were derived feeding experiments. To determine...

The majority of plant proteins used in aquatic feeds are derived from seed meals, which may contain antinutritional factors. Protein concentrates foliage have received less attention fish feeding trials. Alfalfa protein concentrate (APC) is fresh alfalfa that contains approximately 52% and low fiber. A trial was done to assess growth feed efficiency responses yellow perch (Perca flavescens) fed...

An eleven-week feeding trial was conducted to evaluate the growth effect of partial replacement of fishmeal by the microalga Spirulina platensis in the diet of juvenile Pacific white shrimp Litopenaeus vannamei (Boone). The results clearly indicate that Spirulina platensis constitutes an effective food ingredient for shrimp. Growth rates of a Spirulina-fed group differed highly significantly (p...

Initiation of mRNA translation and elongation of the polypeptide chain are 2 regulated processes responsible for the short-term postprandial acceleration of protein synthesis in animal tissues. It is known that a chronic increase in the absorptive supply of AA stimulates protein synthesis in ruminant animals, but effects on translation initiation and elongation are unknown. To determine whether...

Farming of fish and especially farming of carnivorous fish depends on high protein diets. Atlantic salmon (Salmo salar) generally require 55-60% of dietary protein in juvenile stages thereafter the protein requirement declines (NRC, 1993). Historically the protein source has been fishmeal, produced from wild caught fish, while the lipid source has been the fish oil from the same source. Product...
