A lawsuit filed by Stanford law school has asked for an injunction to stocking non native species of fish in California waters. A California Superior Court Judge has ask the DFG to seek a solution to the fish stocking program by meeting with the petitioners.
The lawsuit is over fish stocking programs that have been conducted by DFG without an Environmental Impact Report (EIR) for the programs. The DFG, however, is conducting EIRs because of a 2006 lawsuit. It was filed by the Pacific Rivers Council and the Center for Biological Diversity. These studies will not be completed until 2010. Hmm ... I wonder if there has been any EIRs completed for the illegal stocking of humans that deplete the fisheries, native and otherwise, in California? Or, the lack of law enforcement personal to protect native species.
If an agreement is not reached between the DFG and the petitioners, an injunction could be issued to halt stocking of non-native trout and salmon. It would seem the environmental impact of this would be devastation of native populations by legally and non legally established humans who wouldn't have stocked trout to prey on.
Most of all the trout stocked in California are not native to the waters. Of course, most all of the lakes in California are not "native" either. Does stocking trout in a man made lake have any significant effect compared to the man made lake itself? The trout stocked in rivers like our Santa Ynez and local creeks are stocked with a non native trout strain. To stock native fish, they would have to raise a Steelhead strain.
I believe an agreement will be reached and stocking will continue. The economic impact will play a larger role than the environmental impact; it usually does. That's why the judge is asking the parties to reach an agreement.
