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.

Methionine hydroxy analog supplements low-fishmeal shrimp diets
In a study, the authors evaluated the performance of juvenile white shrimp grown at high density and fed diets with varying levels of methionine. Trends toward improvements in feed intake were observed for diets with reduced fishmeal and HMTBa supplementation.

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.

Mutton snappers grow well on plant-based diets
A study in Brazil indicated that mutton snappers, a high-value species that readily accepts artificial food, can grow well on diets containing high-quality plant proteins such as soy protein concentrate.

Fishmeal, fish oil not limiting factors for aquaculture
The amount of fishmeal and fish oil used in aquaculture has remained static, while output from aquaculture has increased.

Nutritional compensation supports fishmeal replacement in sea bream feed
In a study with gilthead sea bream, two test diets used primarily soy products as sources of protein and fat against a reference feed based largely on fishmeal and fish oil.

U.S. agencies focus on fishmeal in feed
The National Oceanic and Atmospheric Administration and U.S. Department of Agriculture joined forces through the NOAA-USDA Alternative Feeds Initiative to identify feed ingredients that will reduce the amount of fishmeal and fish oil in aquaculture feeds while maintaining the human health benefits of seafood. Through research on a variety of sources, promising alternatives are beginning to emerge.

Alternatives to fishmeal perform well in low-salinity shrimp farm trial
In a white shrimp farm trial in a low-salinity environment, alternatives to fishmeal did not negatively impact the growth, survival or FCR of the shrimp.

Fishmeal replacement in diets effective at shrimp farm trials
Shrimp farm trials demonstrated the feasibility of fishmeal replacement with soybean and corn gluten meal with little adverse effect on production performance.

Soy products replace fishmeal, fish oil in gilthead sea bream feed study
A laboratory study indicated gilthead sea bream can be grown on feeds in which fishmeal and fish oil levels are reduced from traditional values using soy products.

Fishmeal replacements: Rendered protein meals effective
Research indicates that rendered protein meals could replace significant amounts of fishmeal in diets for shrimp and several cultured fish species without reducing weight gain.

Meta-analysis examines ingredient substitution for fishmeal in salmon, trout feeds
In a meta-analysis of 28 nutrition studies, the authors found limited possibilities for ingredient substitution for fishmeal in diets for salmon and trout.

Indian farmers consider white shrimp
India farmers are considering ways to boost production. If approved on a wider basis, production of Pacific white shrimp could boost overall yields.

Fishmeal, fish oil replacements in sea bream, sea bass diets need nutritional compensation
Fishmeal and fish oil replacements present a challenge for the aquafeed industry. The range of alternative protein and fat sources is limited, given multiple considerations.
