Benefits of saponin supplementation to tilapia

The nile tilapia is by far the most commonly used species in fish farming. However farming of this species in ponds results commonly in early maturation as low as 70 g fish body weight only. Hormones can be used to control reproduction to produces good-size fish, although they can pose some risks to human health. Saponin can be a good alternative to control reproduction according to Christian Lückstädt, Paz Kühlmann and Yasmin Primavera-tirol.

Mycotoxins – a rising threat to aquaculture

Plant ingredients pose a high risk of mycotoxin contamination. As the aquafeed industry moves towards using more plant ingredients, Peter Spring explains why both risk assessment towards mycotoxins and development of appropriate protection strategies will become an integral in aquaculture nutrition.

A balanced nucleotide supply makes sense

Free nucleotides in the diet of animals can be a powerful ally against stressful situations occurring at certain stages of development, either with or without associated pathologies. Gaining popularity already in pig and poultry feeding, the building blocks of DNA and RNA are equally valid in aquaculture applications.

Alternative protein sources for farmed salmon

It seems that the MBM ban is not only hitting the animal feed industry hard. Increased demand for fishmeal is pushing up prices, leading the aquaculture sector to look for new protein sources, both plant and animal. Whilst growth and efficiency of alternatives will probably determine their eventual use, the effects on immune function should not be overlooked.

Astaxanthin: not only a pigment, but a health enhancer too

Astaxanthin is a naturally occurring carotenoid that pigments salmon, trout and other forms of seafood. Astaxanthin is routinely added in aquaculture diets to enhance natural pigmentation. Because of its unique bioactive properties, new promising uses also include enhancement of ealth, reproduction, and overall performance in fish, poultry and livestock. While synthetic astaxanthin dominates this market, the unique properties and consumer appeal of natural sources of astaxanthin like Haematococc...
