“Their regular cycle is triggered by just a few issues,” he stated.
“It is not solely rainfall, it is also day size, it is temperature, and it is also thunder and lightning.
“You will at all times get some manufacturing with day size and the rise in water peak as we pump in additional water within the dams, however boy what a distinction it makes once we get an early moist season.

“We simply get crocodiles going on the market desirous to procreate, desirous to mate, women lay extra eggs, fertility charges go up.
“So sure I am involved. If we get a drought, now we have a median egg lay, common fertility and we hate being common.”
He stated timing was essential with rain wanted originally of the monsoon season.
“And not using a good begin and an early begin, we will stand up to 50 per cent manufacturing solely,” he stated.
“Whereas you get a very good yr, effectively it is a increase — issues occur.
“With crocodiles, if we do not get the rain in November/December, then we’re actually pushing it to get a very good season.”

Mr Lever stated the farm had confronted El Nino circumstances earlier than.
“Within the 90s we had a run, I believe it was six years in a row the place we had very late seasons, no rainfall till after Christmas, which is simply too late for the crocodiles,” he stated.
Mr Lever stated sadly there was little or no they might do to mitigate towards the results of drought.
“We have tried all types of issues like taking part in Beethoven’s Fifth to them over the water, you already know doing all the pieces we will to stimulate the crocs into going to mate,” he stated.
“Nothing appears to work till you get a thunderstorm after which it is super for the exercise.”
Mr Lever stated crocodiles within the wild have been precisely the identical.
“If they are not nesting, the ladies aren’t territorial,” he stated.
“The males will at all times change into territorial round this time of the yr, just because they’re out looking for females however the searching effort is quite a bit much less when it does not rain.
“When you have got a drought yr their searching is much less, their territoriality is much less — you get a pleasant early moist season, all of it spikes.
“And also you get excessive territoriality, crocodiles wanting to extend their territory to allow them to discover extra females and that is once we discover them turning up in uncommon locations.”
