YARALLA DEEP SEA FISHING CLUB 2002-2017

Catch data were provided by the Yaralla Deep Sea Fishing Club for the period 2002-2017. The Club has mainly fished around the Capricorn-Bunker reefs and shoals to the north involving 2-3 day charter trips. The rezoning of the Great Barrier Reef Marine Park came into effect in 2004 which resulted in a significant increase in “green” no fishing zones and that had an effect on some of the locations fished by the Club.
