Re: [APD] Surface scum -- or Evicting tenants

["S. Hieber" <shieber at yahoo_com>]

Net what you can.  For the stragglers and net-shy fish,
bottle traps work.  But it takes patience.  Release wrong
catches and retry until they're gone.

Take a small plastic water bottle.  Cut off the top and
invert it like a funnel. Put some holes in the bottle to
hold the funnel in place and allow some water circulation.
Hold funnel in place with small pieces of toothpick.  

Add small amount of food.
