Was going over the California DOJ website and found this

The prohibition from carrying a concealed handgun does not apply to licensed
hunters or fishermen while engaged in hunting or fishing, or while going to or
returning from the hunting expedition . (Pen . Code, § 25640 .) Notwithstanding
this exception for hunters or fishermen, these individuals may not carry or
transport loaded firearms when going to or from the expedition . The unloaded
firearms should be transported in the trunk of the vehicle or in a locked container
other than the utility or glove compartment . (Pen . Code, § 25610 .)

Does this mean i can legally conceal while fishing without a ccl licence? Don't want to break any laws
