First-ever rotifer substitution diet
First-ever rotifer substitution diet enables hatcheries to reduce their rotifer demands by more than 50%, improving survival rates and overall fry quality. Check out some trial results at commercial scale.
Nutritional Composition, Quality and Hazards Profiling of Commercial Post-Larval Feeds Used in Litopenaeus Vannamei Hatcheries
Nutritional profile and quality of commercial post-larval (PL) feeds (n=9), zoea feeds (n=2), mysis feeds (n=2) and artemia cysts (n=2) of different brands used in Litopenaeus vannamei hatcheries located in Andhra Pradesh on the east coast of India were assessed. The study revealed the need for good manufacturing practices (GMP) and screening of all feed components for antibiotics, pesticide residues and heavy metals.
Polychaete Feeds
A new company is harnessing the well established benefits of marine worms with the advantages of extrusion technology, to produce feeds for a variety of aquacultured species and growth stages
Protein quality of larval feed with increased concentration of hydrolysed protein: effects of heat treatment and leaching
Four heat coagulated early weaning diets with increasing concentrations of pepsin hydrolysed protein, were investigated with regard to the change in protein quality during feed production and exposure to leaching
Replacement of live feed in marine fish hatcheries feasible
Replacing live feed to a great extend in the production of fry of marine fish species such as gilthead sea bream (Sparus aurata) and European sea bass (Dicentrarchus labrax) is feasible, from a technical point of view. This has been clearly demonstrated in recent trails conducted in Mediterranean hatcheries utilizing BioMar’s LARVIVA ProStart diet.
Study tests SCPs potential use in juvenile kingfish
Aussie researchers tested replacing fishmeal with SCPs in juvenile yellowtail kingfish aquafeeds and are now finding a way to improve palatability and increase the replacement rate.
Substitution of live food by formulated diets in marine fish larvae
Recent research has led to the formulation of a compound diet that was well adapted for larvae from mouth opening, and could totally replace live prey...Read more.
The Effects of Live and Artificial Diets on Feeding Performance of Winter Flounder, Pseudopleuronectes americanus, in the Hatchery
The objectives of this research were to determine how different diets (both live and formulated) influenced hatchery survival and growth of juvenile winter flounder.Michelle L. Walsh1, Elizabeth A. Fairchild, Nathan Rennels and W. Huntting Howell
What is the optimal dietary vitamin D level in gilthead seabream larvae?
A study finds that the recommended dietary vitamin D3 level for gilthead seabream larvae may range between 25 and 30 μg kg−1, which improves larval survival and reduces the incidence of skeletal anomalies.
