The Loch Ness "monster" is little more than a fabricated tourist attraction. The fact is that there is no real evidence for the existence of any large creature in the loch other than anecdotal accounts and a few very indistinct photographs, many of which have conclusively been proven to be faked. Additionally, the loch is too small a body of water to support a life form that would have to be at the top of the food chain. Whale-sized creatures require whale-sized sources of food and the loch is entirely lacking in that regard.
