Moving toward sustainable fish feeds
The aquaculture industry has significantly reduced fishmeal levels in feeds for major farmed species. To further reduce fishmeal use, new research approaches are essential.

Tilapia production using biofloc technology
Biofloc systems enable more intensive tilapia production. The fish adapt to the conditions within biofloc systems and grow well by utilizing the bioflocs as a feed source.
Responsibility
Life cycle assessment in aquaculture
Life cycle assessment studies the environmental and other potential impacts throughout a product’s life, starting at raw material and following it through production, use and disposal.

Microbial flocs spare protein in white shrimp diets
The authors conducted a study to determine how reducing the protein content of a diet would affect the growth performance of L. vannamei reared in an experimental microbial floc culture system.
Health & Welfare
Methionine requirements estimated for white shrimp
Research on the methionine requirement for white shrimp showed a diet requirement of 0.45 percent using a protein-bound form of methionine.
Health & Welfare
Protein hydrolysates in larval fish nutrition
Protein hydrolysates are currently used as partial substitutes for fishmeal in high-quality artificial diets since their inclusion in feeds promotes growth and survival.

Genetics, environment define crustacean color
Coloration in crustaceans is affected by a combination of factors: diet, environment and genetics. The genes required for coloration are not present in any other animal, but crustaceans use them to create a variety of colors and shell patterns.

Protein profiling: Evaluating the condition of farmed Atlantic salmon
A study developed a rapid, nondestructive and sensitive method to evaluate the condition of farmed Atlantic salmon using mass spectrometry with protein chip technology.
Responsibility
Protein, lipid recovery from fish-processing byproducts
West Virginia University developed a lipid and protein recovery process from byproducts that reduces disposal concerns in the process of fish processing.
