If I may add to Mr. Lusk's thoughts, The Gent I work under in my home state here is a firm believer in a "hard" sample. Too many factors can cause good and/or bad samples, so in his mind (and mine), it's best to get as good of a representation of the population as possible.
Our Walleye egg-take is a great example of this. We're gathering for other purposes but the over-all sample really gives the best data of average conditions present, whereas a bad night of fall samples can be extremely misleading, hence the reason we give a good hard effort for 10-12 days/nights.
Makes good logical sense.
EDIT: Sorry Mr. Cody, I type too slow.
