  1. 1. Baltic blue mussel (Mytilus edulis L.) and black soldier fly (Hermetia. illucens) combined with pea protein concentrate as protein sources in feed for rainbow trout (Oncorhynchus mykiss)

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Xiaoqing Cui; [2019]
    Keywords : aquaculture; rainbow trout; Baltic blue mussel; black solider fly larvae; digestibility; protein; fishmeal replacement;

    Abstract : A feeding trial was conducted for 9 weeks to test the growth performance, nutrient retention and digestibility in rainbow trout (Oncorhynchus mykiss) in order to assess the potential of Baltic blue mussel meal (Mytilus edulis L) and black solider fly larvae (Hermetia illucens) meal as protein sources. The dietary treatments consisted of one control diet based on high quality fishmeal, one control diet based on pea protein concentrate for testing dietary palatability and two fishmeal-free experimental diets where approximately 20% of the crude protein from the fishmeal was replaced with the protein from either de-shelled blue mussel meal or larvae meal on a dry matter basis.

  4. 3. Fatty acid composition of black soldier fly larvae : impact of the rearing substrate

    University essay from SLU/Dept. of Energy and Technology

    Author : Nils Ewald; [2018]
    Keywords : Black soldier fly; Hermetia illucens; fatty acids; omega-3 fatty acids; malondialdehyde; blue mussels; waste management;

    Abstract : With an increasing world population and meat consumption the black soldier fly (BSF; Hermetia illucens) shows potential as feed for animals, while recycling nutrients from food waste. To produce larvae of high quality as animal feed, further understanding is needed of how the substrate affects the nutritional composition of the larvae. READ MORE
