1. Brewer’s yeast as a protein source in the diet of tilapia (Oreochromis niloticus) and freshwater prawns (Macrobrachium rosenbergii) reared in a clear water or biofloc environment
Sammanfattning : This thesis investigated the effects of dietary protein replacement of fishmeal or soybean meal with spent brewer’s yeast (SBY) in farmed tilapia and giant freshwater prawns. The effect of rearing tilapia and prawn in two different rearing systems, clear water recirculating aquaculture system (CW-RAS) and biofloc recirculating aquaculture system (Bio-RAS), were also investigated.

2. Single cell protein in fish feed: effects on gut microbiota
Sammanfattning : The microbiota has been shown to be important for nutrition and health. It provides the host with an extensive arsenal of dietary enzymes that can contribute to host metabolism by conversion of otherwise undigestible compounds to metabolites that the host can utilize. LÄS MER
3. Nutritive value and use of locally available low-cost feed ingredients for tilapia farming in Tanzania
Sammanfattning : Fish farming has become popular in Tanzania in recent years, resulting in an increase in the number of fishponds. This has caused a corresponding demand for good-quality fish feeds at affordable prices, for sustainable aquaculture production and productivity. LÄS MER
4. Alternative feed sources : Effect on gut microbiota, immunity and health of rainbow trout
Sammanfattning : Shifting from conventional fishmeal- and soymeal-based aquafeed to low-cost, sustainable dietary alternatives is essential for expansion and resilience in aquaculture. Possible alternative feed resources include under-utilised organic wastes from agriculture and households and by-products from forestry. LÄS MER
5. Evaluation of locally available feed resources for striped catfish (Pangasianodon hypophthalmus)
Sammanfattning : This thesis investigated and compared inputs and outputs, economic factors and current feed use in small-scale farming systems producing striped catfish (Pangasianodon hypophthalmus) in the Mekong Delta. The nutrient content of locally available natural feed resources for striped catfish was determined and growth performance, feed utilisation and body indices were analysed in pond-cultured striped catfish fed diets where fish meal protein was replaced with protein from local feed resources.
