"I'm sick of this, we have this sort of thing happening every year and I'm determined to turn poachers into hunters."
Mr Davis wants to hear from anyone who may be able to identify the man or dog in the photo.
"Someone will know if there's a keen hunter out there using a pushbike to get around," he said.
"It's also about safety and having the common courtesy to ask farmers for permission to be on their land, and to give property owners the opportunity to say no."
Mr Davis said farmers had told him they were sick of poaching, with one saying he would put up a sign saying "no shooting".
"I'd rather see a sign which says 'no permission, no shooting'," he said.
"That spells it out pretty simply." He said the suspected poacher "would have had no idea what he was likely to encounter on this farm and I can understand the farmer's anger.
"It's lambing and calving time and the pressure is on farmers throughout the district."
