Non-additive genetic effects in Nile tilapia
Joshi, Rajesh (PhD Thesis;2018:101, Doctoral thesis, 2018)Nile tilapia (Oreochromis niloticus) is the world’s fastest growing aquaculture species, in terms of annual increase in production (ca 10%) and is today produced world-wide. Most of the commercial and farmed Nile tilapia ... -
Reproductive and Genetic Studies in Large Yellow Croaker
Yu, Xinxiu (Doctoral thesis, 2021-12-15)Large yellow croaker (Larimichthys crocea) is distributed in the coastal regions of East Asia and is one of the most important marine aquaculture species in China. However, due to overfishing, it has been difficult to ... -
Statistical model comparison in genetic analysis of challenge test data on Streptococcus agalactiae resistance in Nile tilapia (Oreochromis niloticus)
Lin, Meng (Master thesis, 2016-08-09)Five statistical models were used to analysis genetic variations, heritability and the ability to predict survival of Nile tilapia based on challenge test data. 12 full-sib Nile tilapia families (1870 individuals) with an ... -
The domestication of Oreochromis mossambicus in a breeding program in Mozambique
Torres Arjona, Guillermo (Master thesis, 2018)This study describes the establishment of a baseline and a base camp for the development of a genetic enhancement program for the Mozambique tilapia, Oreochromis mossambicus, with the scope of utilising both additive and ... -
The neural basis of threat-sensitive behaviour in fish
Silva, Patricia Isabel Mota (PhD Thesis;2015:6, Doctoral thesis, 2020-11-10)Fear, or threat-sensitive behaviour, is an emotionally guided response allowing animals to minimize exposure to potential danger. Stress is a set of physiological/behavioural responses to such exposure. Among other ... -
Variation at early life stages of Atlantic salmon : relationships between emergence time and stress coping styles
Serrano, Jonathan David Vaz (PhD Thesis;2011:08, Doctoral thesis, 2011)Captive fish are exposed to a variety of stressful situations, which can affect growth rates and promote diseases. Identification and selection for stress resistant fish at early stages of the production cycle could be ...
