NSW estuaries are subject to significant commercial and increasing recreational fishing pressure. Increasing the relative abundance of fish by restocking is a popular concept with many anglers, aquaculture businesses and politicians, especially with the recent introduction of a marine angling license in NSW. It is also an emotive concept to estuary management committees and some fishing groups, but there is little information on the possible impacts. This proposal will examine the environmental impact of releasing juvenile mulloway - a top level predator - on local forage species in two target estuaries, and thus make predictions for management of restocking.Read moreRead less
Establishing an ecological basis for stocking density of Australian bass in freshwaters: Experimental field tests of a general numerical model. Large numbers of the Australian public go fishing, particularly in rivers and impoundments. Angling in these waterways provides a strong source of income for rural and regional communities. The stocking of native fish to support inland angling also sustains much of the aquaculture industry in western NSW and Queensland. This study will develop an optimal ....Establishing an ecological basis for stocking density of Australian bass in freshwaters: Experimental field tests of a general numerical model. Large numbers of the Australian public go fishing, particularly in rivers and impoundments. Angling in these waterways provides a strong source of income for rural and regional communities. The stocking of native fish to support inland angling also sustains much of the aquaculture industry in western NSW and Queensland. This study will develop an optimal approach to stocking Australian bass which is relevant for other stocked freshwater species, and will allow stocking to be undertaken in an environmentally responsible manner. This will both enhance the outcome of investment of public funds in stocking, and enhance the recreational fishing experience that is so important to rural regional communities.Read moreRead less
