Summary This project will determine how the timing of sexual maturation, an important aspect of salmon developmental biology, is influenced by genotype and its interaction with environmental conditions in modern culture systems. The prevalence of early maturing males can be >90% in modern facilities and is a welfare and economic concern in salmon farming, since sexual maturation slows growth, lowers disease resistance, and decreases flesh value. Our objectives are to i) increase our knowledge on the environmental triggers of precocious sexual maturation in male salmon, ii) find a new biological marker to readily identify fish that have initiated puberty, and iii) understand how genotypes that effect the age of puberty influence physiology. The projects critical challanges are to provide research animals with genotypes of interest, providing the environmental conditions of relevance to the industry, and acquiring the resources to undertake the latest "omics" technology. To accomplish these, we have relied on the resources available at the Institute of Marine Research and the breeding company Salmobreed AS to produce broodstock. In addition, we have state of the art tank facilities and expertise in RNA sequencing and genotyping at IMR, while our national and international partners have expertise in reproduction, smoltification, and lipidomics and metabolism in salmon. The knowledge obtained from this project will provide the industry with information on the environmental and genetic conditions that can trigger early precocious maturation in male salmon, leading to new strategies to avoid such occurences and increase the sustainability of salmon farming. In addition, we hope to provide new, ethical, biological markers to detect early puberty in fish that would be of interest to the industry and researchers alike. Finally, we hope to increase the knowledge on the basic biology of puberty in verterbrates that would be of interest to the wider research community and society.
