Enhanced biodiversity of gut flora, feed efficiency in Nile tilapia under reduced-frequency feeding
Reduced-frequency feeding strategies improve the production efficiency of Nile tilapia operations and do not affect growth or survival rates.
‘We will very likely find it’: Microplastics warning sounded for aquafeeds
The warning about microplastics pollution is finding its way to aquaculture, as a new study finds contaminated samples of fishmeal, a prominent aquafeeds ingredient.
Macronutrient research in aquaculture nutrition
Proteins, lipids and carbohydrates require equal consideration for aquafeed formulators, as each macronutrient influences performance and feed conversion.
Fish nutrition will fuel aquaculture’s future
Dr. Monica Betancor, a lecturer at the University of Stirling, talks about the “intrinsic link” between fish nutrition and, ultimately, human health.
Use of a filamentous green alga and a microsnail as feed for black tiger shrimp
Authors evaluate production efficiency of a filamentous green alga and a microsnail as feeds for black tiger shrimp (Penaeus monodon).
Updating nutritional research strategies for the optimal evaluation of aquafeed ingredients, part 2
Standardizing the assessment process of aquaculture feed ingredients using a structured approach for assessing their quality.
Updating nutritional research strategies for the optimal evaluation of aquafeed ingredients, part 1
Many strategies can be used to assess the nutritional quality of ingredients. The choice, however, can impact the interpretation of that information.
Could microalgae culture on a conveyor belt catch on?
Alabama-based startup is developing a conveyor belt system to culture microalgae in less space than raceways and with a more efficient collection system.
Comparing microalgae-blend diets to reference diet for Nile tilapia
Nutritional study with Nile tilapia compared three microalgal diets to a reference diet containing fishmeal and fish oil levels found in commercial feed.
Is removing marine ingredients from largemouth bass diets possible?
Trials unambiguously demonstrate that marine ingredients can be removed from largemouth bass diets without hampering growth, health or flavor.
Evaluating seaweed, formulated diet on growth, gonad quality of sea urchins
An evaluation of the effects of fresh seaweed diets and manufactured feeds on growth and gonad quality of adult, wild collector sea urchins.
Effect of dietary non-starch polysaccharides on tilapia productivity in ponds
An assessment of the effect of type of dietary non-starch polysaccharides (NSPs) on the productivity of tilapia cultured in ponds.
Modeling microalgae production cost in aquaculture hatcheries
A modeling evaluation of microalgae production costs in aquaculture hatcheries, along with cost reduction and optimization methods.
NovoNutrients partners up on its pathway to commercialization
NovoNutrients will join FEED-X, an initiative to transform the “sustainability performance” of value chains linked to climate change and biodiversity loss.
Evaluating effects of dietary soybean isoflavones in grass carp
This study evaluated the effects of dietary soybean isoflavones on several production and quality parameters of grass carp flesh.
Counterpoint: Marine ingredients are stable in volume, strategic in aquaculture nutrition
IFFO Director General Petter M. Johannessen says fishmeal and fish oil offer unmatched nutrition and benefits to fuel aquaculture’s growth trajectory.
