Re: More on Crawfish
From the responses (Alton/Echo Point, Wolfeboro, Mink, E. Rattlesnake) it seems that crawfish are "MIA" from the south/southeastern 1/3 of Winnispesaukee.
One respondant suggested it was lack of Town sewer service. That doesn't explain our shoreline's lack of crawfish -- our shoreline has only changed in one way (two new lawns in 1980 -- another in 1991), and we're still a mile from the nearest Town sewer line -- after 50 years. (And we've turned over a lot of rocks in the last 30 years).
Another suggested lawn fertilizer. That increase in nitrates and phosphorus could explain our damaged crawfish habitat. Though there has been a lot of washing-out (due storms) of driveways/Title V septics and weekend silting from wave action in the last fifteen years.
I like the suggestion regarding a study/thesis of suburban night lighting. (But usually that results in more activity -- not less. Plant two trees in your front yard. The one nearest the streetlamp grows larger).
I've learned that "crawfish/crawdads" is Southern-talk, and we have crayfish "up North".
But "Crawmoms" always existed. You can flip over any crayfish and determine that for yourself. (I mean "craymoms").
Now I've got to check out if crays are really "aquatic insects".
