Full-sib mating also results in a substantial decrease in fitness (inbreeding depression), and thus a high riskofextinction of the population. The cost of fishing licences should be increased in order to restrict the capture of species that are at riskofextinction. However, the process of purging also results in an increased riskofextinction and loss of genetic variation. For each selection scheme with any family size, line crossing decreases the riskofextinction with little change in the effectiveness of purging. Farm populations are at high riskofextinction due to pest management programmes and fallowing of sites. One possible way to purge the mutational load gradually without a high riskofextinction is to change the rate of inbreeding during the whole purging period. Compared with no crossing, line crossing could lower the riskofextinction and the inbreeding coefficient of the purged population substantially with little loss of the effectiveness of purging. The result is of significance in practical purging programmes which aim to purge inbreeding depression, improve fitness performance without much riskofextinction and loss of genetic variation. It is essential that the species now in danger, some of them at serious riskofextinction, survive. From the Hansard archive Example from the Hansard archive.
