some interesting informative material,his thoughts that fish can detect the h.n.v of a bait is consistent with my findings,and the baits application is very important.
going back 15-20 years i pre-baited a lake with the hi-nu-val through the winter months,the lake contained 25-30 fish,the largest was a common that had only ever been caught once to our knowledge,a very wily old charactor,cut a long story short' i caught the common on my very first trip useing the bait,i packed up very happy that day,returned a few days later and caught it again along with the lakes largest mirror carp.
