Dividends from snapper stock
A GOSNELLS personal trainer is the new Guinness World Record holder for doing the exercise gymgoers love to hate. Levi Kissick Ponga last month smashed the record for the most chest-to-ground burpees in one minute to raise money for cancer research ahead of Daffodil Day this Friday.
Mr Ponga said it was a cause close to his heart after watching his older brother Cory go through prostate cancer treatment and losing family members to the disease, including his grandfather.
“As I was doing it, I was telling myself that the pain is nothing like what cancer patients go through,” he said.
The father-of-two managed 34 chest-to-ground burpees in just 60 seconds – beating the previous record by four – in front of a crowd of more than 70 supporters at Plus Fitness Wattle Grove.

That will be before Cockburn and Warnbro sounds close to protect breeding stocks for four months from September 31.
“Many of these fish are the result of a very good population recruitment pulse from 2007 and are likely to form part of the aggregations,” Department of Primary Industries and Regional Development fisheries management officer Shane Walters said.
A large recreational fishery for the prized species has developed in the months before the closures each year, which followed a 2001-04 study of their spawning in multiple places in the sound.
It is not unknown for up to 100 small vessels, including kayaks and tinnies, to fish spots in evenings and dawns where a pre-closure school of snapper has become known, in part because of social media posts.
Mr Walters said the number of snapper annually joining the population comprised one to two strong years each decade, with weaker seasons between.
“Spawning activity is usually at its greatest between October and December, but typically peaks around the new moon at the time when water temperatures reach 19C to 21C, typically in November,” he said.
Some recreational fishers opposed to a new outer harbour at Henderson say adjacent wharves and groynes are a prime site for breeding.
However, a Journal of Fish Biology paper showeds snapper spawning areas throughout the sound, starting in its deep basin and moving clockwise as breeding progresses.
