a couple of tips for Jamie B; ill start with the coons, fierce little critters i raised one when i was young. get the first step off the ledge of the pond OVER 12 inches. so if yo plan on rocks planters etc make the first step deeper. they dont like deep water and they must swim ...in the winter , dont run the pump if they are anywhere close they will hear the water falls and they are attracted to the site. use traps .if you relocate them make sure its at least 3 miles away from any creek thats close.dont want them coming back. you really gotta watch them when the first sign of water getting cold or ice coming. there is only a couple of hawks that specialize in catching fish..you live in the sticks ...[12 ga] does the trick. or stretch a net over os they cant swoop down.. fishers i have NO clue i never saw one. the big killer that is keen is the Heron....dogs will be a huge help,around here i have friends that use the newer camera systems that hook up to the new smart phones. they have a grid you can spread around the areas you . anything hits the grid triggers the alarm is sent to you phone DAY OR NITE 24/7 one buddy has a remote hooked to a big boom box!! the heron comes in he sets it off and it scares it away. he does this from work. i have caught people here coming in my property with nets, going after my fish i have sent 2 to jail .if you live in the sticks here are a couple you gotta watch close... mink, weasels, otters ... otters are killers if they come in they will kill everything and leave it lay..if you have a creek anywhere close you better take extra steps...dogs do a good job. i use a electric fence around my fence top , a STRONG jolt deters most.... but every once in a while i get a cat, huge coon that manages to get over and does not wanna go back over because of the jolt. cats.. i had a neighbor once... had a big tom caught him in a trap[have a heart] i had words with her she seemed to make countless jokes about my fish and her cat,,, after returning it 3 times before, the 4 time i took a electric barber clipper to the critter shaving all the hair off except a puff around the tail and head to make it look like a lion..i see you a cat lover i dont wann offend you no harm to the cat, giant big persian ...and i didnt return him i let him go... i never had another issue with him......hope this helps to save a few fish...mike
