Rockfish

One of the ongoing projects in our lab is on the conservation genetics of rockfish, in the genus Sebastes. We address a variety of questions with this group including questions of local adaptation and conservation of the commercially important group of fishes. We have continued concern for the future viability of the rockfish fishery due to previous management issues and the effects of global climate change. The main focal group of Dr. Burford Reiskind is the genetic structure and cryptic speciation of blue rockfish. Currently, we are using a population genomic approach to investigate any geographic structure in the two species of rockfish (Sebastes mystinus Type 1 and Type 2, see publications). In addition we are developing methods for investigating the degree of hybridization between these two distinct species. Another ongoing project in our lab is an age-structured genetic study on the kelp rockfish (Sebastes atrovirens) in central California. We are using mtDNA Control Region sequence data and comparing geographic genetic structure of adults and juvenile recruits.
