Rumor has it that Nessie ate one human, sometime
around the year 700 AD. Perhaps he tasted bad. Perhaps Nessie gained
respect for humans. Perhaps all the local folk praying for safety from
Nessie had an effect. Whatever the reason, Nessie has never eaten
another human since.
Loch Ness has plenty for her to eat.
Estimates of the fish population in Loch Ness, are as high as 27 tons.
They include: Salmon, Sea Trout, Brown Trout, Pike, Eel,
Char, Lamprey, Minnow, Stickleback, Sturgeon, Wels, and Flounder. And
that's mainly in the top 5 feet of the Loch. The Loch is over 700
feet deep, but the water is murky. If Nessie is able to fish in the dark,
she must be able to detect food with more than eyesight alone.
Perhaps she uses sonar like bats.
Perhaps she is vegetarian. Plenty of
leaves fall into the Loch. Zoo-plankton are plentiful.
Whatever Nessie likes to eat, Loch Ness has enough food to support
dozens of her family, without eating visitors to the Loch.
