i did some reading on dolly varden and found that they usualy dont dig for eggs as they catch stray eggs as stilly bum mentoined. if those unfertalized eggs were to settle in with fertalized they could spoil the nest , so i guess they are helpful in the rearing process. i know that all native fish play an important roll. another interesting fact i found was that the dolly varden was named after a character in a Dickens novel "barnaby rudge". Dolly varden wrote Dickens was "the very impersonatoin of good-humer and blooming beauty" i guess the first angler to catch one thought the same. thanks for all who posted and i will continue to
