After reading all the responses above, it would appear that water trapping requires a lot more work than predator/land trapping? Lots of equipment, gear and fastening systems. Just an observation.
LOL! Canine trapping was waaaay easier and less work than beaver trapping for sure! Coyote were a little stinky and initially difficult to flesh but better than hauling a 50# bag of guts up steep, high banks and I never had to haul a sled load of coyote through 1/2 mile of tagalder swamp even on ice like I’ve done with beaver! Otter, mink, & rats are pretty easy especially trapping on ice and LIGHT to haul as is the equipment! It’s also way easier to find coyote & fox sign in my territory than mink sign.
BTW, this winter I plan on using an 8” ice auger with drill/driver so there’s an added bulky, heavier piece of equipment but there and again, if you trap hard water you need to be able to get below it! LOL
