Hi Just thinking some might be interested in these published facts I heard about on the Fishing show on the net and wrote some stuff down, previously I did believe that commercial fishing and recreational fishing did have a borderline sustainable impact on the highly used reef areas on Coral Trout (CT) looks like I may have been conned by more pseudo science based propoganda fron GBRMPA? or one of their political bright green alais?
Here it is make up your own mind.
INDEPENDENT Biologist Tony Arling conducted extensive studys on Coral Trout numbers up and down the GBR and here are some results.
Capricorn Bunker Group
12 reefs
6 closed for 5 years
6 open to Fishing
Results
57 Coral Trout/ha on protected reefs
49 Coral Trout/ha on fished reefs
Conclusion -No statistical difference could be shown between the lockout reefs and the free reefs.
Cairns Section
Dunk Is to Lizard Island
1991
29 Fished reefs
18 Closed for 7 years
Results
33.9/ha averaged on Protected reefs
34.6/ha averaged on fished reefs
Conclusion -No statistical difference could be shown between the lockout reefs and the free reefs.
1992
5 protected reefs
5 fished reefs
Results
28.4/ha on protected reefs
27.8/ha on free reefs
Conclusion -No statistical difference could be shown between the lockout reefs and the free reefs.
Long Term Studys
TOWNSVILLE
1983 – 1994
3 Townsville reefs fished commercially and recreationally on:
John Brewer reef
Loadstone Reef (sp)
Davies Reef
Results
