The effect of diet and genetics on male maturation and sperm trait variation in Atlantic salmon

Supervisor: Kenyon Mobley

This project involves analyzing a dataset Atlantic salmon sperm measurements from mature male salmon. The experiment investigates the interactions between diet and the vgll3 gene that influences maturation. Fish were bred from hatchery brood stock to create different vgll3 families and were raised to 3 years of age in a common garden experiment at the Lammi Biological Station in Finland. The experiment was designed so that fish from different families were given either a high energy content food diet or a reduced energy food diet. Sperm measurements were analyzed using Computer Assisted Sperm Analysis and the data are extracted. The student should have familiarity with R programming language and statistics.

Atlantic salmon parr density and sex ratio in the Utsjoki river

Supervisor: Kenyon Mobley

This project involves analyzing a dataset of Atlantic salmon parr collected over 8 years in the Utsjoki river, a tributary of the Tana (Teno) River. Different parr age classes (0+, 1+, 2-3+), maturity, collection area, and genetic information on sex were collected. The goal is to see whether different areas of the sampling area have different densities and sex ratios due to location and year. The student should have familiarity with R programming language and statistics.
