I lived on Merrymetting bay growing up 40yrs ago.And i spend every spare moment on the water and use to see Hundreds of them jumping out of the water.You could see silver streaks coming out of the water all over the river.Some were pretty large 5-10',my Neighbor caught one fishing on bottom it was 6' really neat looking fish..I dont think they run up those rivers like you use to see them.its funny 40 yrs ago that river was the most polluted River in the country and I use to catch tons of fish.
