Histological histochemical and morphological development of striped trumpeter (Latris Lineata) larvae and the effect of larval diet

In November 1992, this project commenced with the development of methods for the evaluation of striped trumpeter (Latris lineata) larvae cultured by the Finfish Development Program (FDP). The first year was spent in the selection of digestive enzymes for investigation and the modification of methods...

Assessment of spatial and temporal variation in puerulus settlement of the southern rock lobster

The overall goal of the present project was to establish a long term puerulus settlement monitoring program for the southern rock lobster (Jasus edwardsii) in Tasmania. Exploratory sampling was conducted throughout much of the Tasmanian coastline to determine key sites suitable for long term...

The development of new techniques for assessing and managing the Australian abalone fisheries

In studies of blacklip abalone (Haliotis rubra) in Tasmania conducted during 1983 to 1987, Jeremy Prince and his research team made several important findings concerning the biology and fishery management of this species. These include: Rate of deposition of growth layers in the shell is...

The development of an index for the prediction of catches of blacklip and greenlip abalone, and a technique for ageing these species

The scientific literature has generally accepted that abalone populations are characterised by low levels of settlement and recruitment (Tegner in press), that mortality is relatively low (Doi et al. 1977; Beinssen and Powell 1979; Sainsbury 1982; Shepherd et al. 1982; Fournier and Breen 1983) and...

Assessment of optimal trapping techniques to control densities of northern Pacific seastars on marine farm leases

The principal aims of this study were to evaluate whether the locally­ produced Whayman-Holdsworth trap provides an effective method for minimising Asterias amurensis infestations on shellfish farms, and to objectively assess the value of seastar traps when used in commercial applications. In an...
