Shark Watch California is a citizen science program giving the community an opportunity to participate in shark science, conservation and education. By contributing observations of elasmobranchs (sharks, skates and rays) in the wild, including human interactions such as encounters and recreational shark catch we can apply this data to conservation. Our network is collecting observations of shark species and spreading education on sharks,their range and human impacts. This data is useful in looking at species ranges, estimating seasonal trends, population size and human impacts. In California we are monitoring recreational and trophy shark fishing, catch, release and kill to evaluate non -commercial impacts on local shark populations.
