For spearfishing champions Ian Puckeridge and his daughter Lara, the Berejiklian government's proposed Sydney marine park to limit fishing at 25 key sites would put an unnecessary halt to a healthy pastime.

"I dive to catch my meal - nothing goes to waste," Ms Puckeridge said on Friday after she and her father gathered the daily bag limit of two abalone each off Bondi.

"We wouldn't be able to dive off South [Bondi]" to spearfish under the new rules, said the 18-year-old student of environmental management at the University of NSW and women's national spearfishing titleholder.

Mr Puckeridge, who has lived in the region for all of his 53 years and held the equivalent male title eight times, said "a lot of the areas they are locking up are so random". These include popular fishing spots such as Shark Point near Clovelly and Henry Head at the entrance of Botany Bay.
