MORE than six months after the NSW government opened up marine sanctuaries to recreational fishing, a new report is warning the pastime can have as much damage as its commercial counterparts.
The Centre for Policy Development report by former World Bank economist Caroline Hoisington, released on Tuesday, said the state's six marine parks were already delivering economic benefits to local communities, bringing an estimated $2.4 million to places like Jervis Bay.
Meanwhile, in the Solitary Islands off Coffs Harbour there are "preliminary indications" that certain fish, such as red morwong, were appearing in greater numbers in sanctuary zones.
"European studies have shown that for each year a fully protected zone is in place, the number and/or size of commercially targeted fish within the park, compared to immediately adjacent areas, increased by around eight per cent," the report states.
Sanctuary zones are areas within marine parks where fishing has traditionally been off-limits.
But in March the government announced it would be granting an amnesty, allowing line fishing from ocean beaches and headlands in these zones.
The centre's report warns, however, that recreational fishing can have a "significant effect on fish stocks".
For some species, such as the bluespotted flathead, recreational catch is estimated to be well above that of its commercial counterparts.
Ms Hoisington's report argues that parks need to be at least 15 years old before they could be properly tested.
With the oldest NSW marine parks barely 11 years and the youngest only six, it was too early to judge.
"Let's hope that we will collectively give marine protected areas enough time to develop and to show the benefits they can bring," the report states.
It comes after Clean Up Australia founder Ian Kiernan warned against the "winding back" of protections for sanctuaries in a report released last week.
