2. 1. Lipid quality of common carp (Cyprinus carpio) in pond culture

   Author : Jan Mraz; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : There is a large body of evidence that n-3 fatty acids, especially EPA and DHA are beneficial for human health. Content of these fatty acids in fish fillet can be influenced by several factors. This thesis examined differences in lipid content, lipid class and fatty acid composition among three parts of common carp fillets. READ MORE

   Abstract : Fish display a fascinating variation in behavior, morphology and physiology among species, among individuals within species, and within individuals over time. A central quest in ecology and evolution is to understand causes and consequences of such variation. READ MORE

5. 3. Lipids in common carp (Cyprinus carpio) and effects on human health

   Author : Jan Mraz; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : There is evidence that n-3 fatty acids (FA), especially EPA and DHA, are beneficial for human health. This thesis examined factors influencing FA composition in common carp flesh, sought to develop a procedure for long-term sustainable culture of common carp with improved muscle lipid quality (omega 3 carp) and studied the health benefits of eating such carp in the secondary prevention of cardiovascular disease.

6. 4. Evaluation of locally available feed resources for Nile tilapia (Oreochromis niloticus) in Rwanda

   Author : Leon Niyibizi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Aquaculture was introduced in Rwanda in the 1940s as an extensive pond-based system but the sector has gained in popularity during the past two decades, resulting in greater numbers of fish ponds and a corresponding increase in demand for quality fish feeds for sustainable aquaculture production. The aim of this thesis was to identify, sample and evaluate the nutritive value of some locally available feed ingredients that could be used by fish farmers producing Nile tilapia. READ MORE
