Sampling regimeTimingThe sampling regime as outlined in Table1 commenced in April 2012 and was repeated inJune/July 2012 providing two separate sampling periods. During each sampling period, tenlocations were sampled (see Table 1). At each location candidate species have beenidentified for sampling. A third sampling was conducted in September 2012, focussing onbarramundi in the Boyne River, considering previously identified ectoparasite issues duringthe cooler months of 2011.Gear typeMultiple gear types were used during the sampling program depending on site and candidatespecies. The gear types were consistent with commercial fishing apparatus and included: gill net / haul net – barramundi, sea mullet, bull sharks and queenfish prawn trawl gear – banana prawn, grinner, Australian threadfin, Castelnau’s herring crab pots – mud crabs.81
