6.12 Protection of portions of popu- 

 lation 



California has regulations pertaining to fish- 

 ing gear and craft and also restrictions on 

 commercial fishing in several relatively small 

 areas. These regulations were not passed 

 specifically to control the jack mackerel 

 fishery and probably have little or no effect 

 on it. There are no closed seasons or other 

 restrictions on the jack mackerel fishery. 

 California law prohibits the use of fish for 

 reduction except that the fish offal may be 

 reduced. The law also provides that the Fish 

 and Game Commission may grant permits for 

 the reduction of whole fish, but none have been 

 granted for any species except sardines, and 

 even reduction of sardines has not been allowed 

 since 1948.
