Coastal floodplain management in eastern Australia: barriers to fish and invertebrate recruitment in acid sulphate soil catchments

Estuarine habitats, and in particular coastal floodplains and wetlands, provide essential nursery habitat for a large number of fish and prawn species, many of which are commercially and recreationally significant. Human activities on coastal land, such as those associated with grazing and...

Summary

The snapper, Chrysophrys auratus, is an economically valuable common property resource that occurs in large numbers in New South Wales waters. Allegations of a resource decline in this major target species of both commercial and recreational fishermen have led to conflict over fishing access and levels of exploitation. In order to investigate claims of a resource decline, the Fishing Industry Research and Development Council funded a three year research project by New South Wales Agriculture and Fisheries.

Summary

The objectives of this study were to determine whether catch rates of rock lobsters in the commercial fishery off New South Wales were declining, the size and species composition of catches from the commercial fishery and to ascertain the smallest length at which 50% of female eastern rock lobsters, Jasus verreauxi carried eggs. In addition, experiments were done to assess the mortality in this species caused by tagging with different types of external tags.

Rock lobsters have been exploited off New South Wales since 1873. Reported annual landings averaged 122 tonnes per annum over the 10 year period to 1983-84 (latest year for which data are available from the NSW Agriculture & Fisheries Annual Reports). Based upon current prices at the point of first sale (Annual Reports of the Sydney Fish Marketing Authority), these average annual landings are worth $3 million per annum . In addition to this however, unreported landings are around 70% of those reported.Four species comprise the commercial catch namely; the eastern rock lobster Jasus verreauxi, the southern rock lobster Jasus novaehollandiae and the painted rock lobsters Panulirus longipes longipes and Panulirus ornatus. The eastern rock lobster comprises around 97% of annual landings in New South Wales.

Evaluation of nanobubble technology in aquaculture

Nanobubble (NB) technology, i.e. the production of ultrafine bubbles with diameters <1 µm, is an emerging field which has the potential to greatly improve oxygenation efficiencies in aquaculture production. Before this technology can be considered for adoption by the aquaculture...

Clarence River pilot prawn farming project

The research programme was largely comprised of farming trials in a 1 ha prawn farming pond and in swimming pools on the pond bank at the field site. Juvenile school prawns (Metapenaeus macleayi) were collected by commercial trawlers in Lake Wolloweyah, transported by punt to the pond where they...
