Abstract : | Currently, there is no information on the genetic structure of the Connecticut river Atlantic salmon population. Among managers and researchers there is consensus that the population was probably bottlenecked by the relatively small founder population, but the initial fish originated from a wide variety of stocks and may be less homozygous than predicted by founder population number alone. An assessment of the genetic variability of the population is required to indicate how present hatchery mating practices may be influencing the level of inbreeding. Methods proposed here will allow virtual elimination of matings of closely-related individuals and will maximize available genetic variability. More information exists on smolt production from index sites on selected tributaries, but it is unknown which tributaries are contributing smolts to the mainstem and adult fish to collection facilities. |
