A blanket ban on fox hunting would not solve the problem of ensuring hunts adhere to the law, MSPs have heard.
His report said some aspects of the current legislation ''complicate unduly'' the detection, investigation and prosecution of offences and there were ''grounds to suspect'' fox hunting takes place illegally.

Giving evidence to Holyrood's Environment Committee on Tuesday, he said he did not believe banning fox hunting and instead promoting drag hunting, where a hunt follows the artificial scent of a fox, would solve the issues with the legislation.
Fox hunting with dogs was banned in Scotland in 2002, with the Protection of Wild Mammals (Scotland) Act stating a person who deliberately hunts a wild mammal with a dog is committing an offence.
An exception is made when dogs may be used to stalk or flush out a fox to be shot for purposes including the control of pest species, protecting livestock or ground-nesting birds.
Mounted hunts in Scotland have since offered farmers, landowners and estate managers a pest control service.
MSP Emma Harper asked Lord Bonomy: "Wouldn't it just be better to promote drag hunting and ban fox hunting?"
He replied: "Judging by the experience in England and Wales, I think the answer has to be no because the number of prosecutions proportionately is more or less the same there... there's lots of apparent breaches of the legislation by inappropriate drag hunting, which is called in fact trail hunting.
"A different material is used so it mimics the scent of a fox and inevitably in many instances where foxes are prevalent a fox appears on the scene.
"So I wasn't convinced that just moving to that instead of other changes like monitoring, I wasn't convinced that that would make any difference."
Questioned on why his review had not recommended a reduction in the number of hounds used to flush out a fox, he said: "I can't think of anything to suggest that reducing it to two dogs would change the situation other than to bring the whole practice of flushing to guns to an end. That change would see an end to hunting as we see it at the moment."
He said it was "impossible to say" if the 2002 law had reduced the number of foxes killed by dogs, currently around 160 each year, as he was not aware of figures prior to the law being brought in.
Following Lord Bonomy's review, the Scottish Government will create a code of practice for hunts and consider developing a new monitoring scheme.
Consultations are also planned on further changes proposed in the judge's report, including removing inconsistencies, extending the time limit for bringing prosecutions, the introduction of vicarious liability, and reversing burden of proof provisions.
The Scottish Greens' environment spokesman Mark Ruskell said: "Lord Bonomy's evidence has confirmed that hundreds of foxes continue to be savagely killed every year by packs of hunting dogs.
"It's outrageous that a law that was meant to ban fox hunting with dogs is being systematically undermined with few consequences for the perpetrators.
"The Scottish Government must act now and legislate to achieve what the Scottish Parliament originally voted for in 2002 - a ban on fox hunting with dogs.
"While there may be a case for limited and humane control of foxes, using packs of dogs is an ineffective and barbaric excuse to continue this outdated tradition."
