1. 1. Replacement of fish protein in fish feed : effects on the yeast flora in the gut of Arctic charr (Salvelinus alpinus)

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

   Author : Hanna Rydmark; [2023]
   Keywords : Microbiota; Saccharomyces cerevisiae; fishmeal; mussel meal; Mytilus edulis; aquaculture;

   Abstract : The aim with this study was to investigate how feeds with different protein sources influence the levels and composition of the yeast flora in the gut of Arctic charr (Salvelinus alpinus). Arctic charr were fed for two weeks on a control diet (C) with fishmeal (FM) or experimental diets with 40% FM replaced by yeast (Saccharomyces cerevisiae) (Y), meal from blue mussel (Mytilus edulis) (M) or a feed with Baltic Sea originated protein; 33% FM, 33% mussel meal (MM) and 33% S.

3. 2. STARTING FROM THE BOTTOM: USING LOW TROPHIC SPECIES IN SALMON FEEDS. Assessing the environmental performance of novel salmon feeds with LCA .

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Moritz Hempel; [2022-08-30]
   Keywords : LCA; Salmon aquaculture; novel feeds; seaweed; blue mussel;

   Abstract : Over the past 30 years, the formulation of salmon feeds has shifted from being based on marine ingredients like fishmeal and fish oil towards more plant-based ingredients. This shift was caused by limited supply of wild fish and general sustainability concerns related to using forage fish for feed, so they were mainly replaced with vegetable-protein. READ MORE

4. 3. 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.
