Evaluating the costs and benefits of research on stock structure for management of the orange roughy fishery

This report describes a procedure for objectively comparing the likely returns from research programs, particularly those designed for fisheries management purposes. This procedure requires that the management objectives for the fishery are well defined, and that the research is directed at...

BCA: DNA microsatellite variation in Atlantic salmon

This report carries out ex-post cost/benefit analysis on three Tasmania Atlantic salmon research projects carried out by CSIRO Marine Research, Hobart. The three projects are analysed together as all are concerned with examining genetic diversity in Tasmanian Atlantic salmon. In addition to the...

DNA microsatellite variation in Atlantic salmon

The aquaculture of Atlantic salmon began in Australia in the mid-1960' s with an importation of ova from Canada to New South Wales. Anecdotal evidence suggested that the Australian population went through a severe bottleneck event during the early years due to poor survival and subsequent small...

Seamount fauna off southern Tasmania: impacts of trawling; conservation and role within the fishery ecosystem

In September 1995, the deepwater trawl fishing industry agreed not to trawl in an area of 370 km2 on the continental slope south of Tasmania for three years, as stated in a Memorandum of Understanding between the former Australian Nature Conservation Agency (now Environment Australia) (EA) and the...

Development of the egg production method to assess the blue grenadier stock in the South East Fishery

The blue grenadier stock is potentially the largest fish stock in the SEF, and following the decline in quota of orange roughy, the need to assess its potential became urgent. The stock has been surveyed using traditional trawl methods and acoustics, but both methods provide only 'snapshot'...

Development of acoustic methods to survey orange roughy in the eastern and southern zones

Three acoustic surveys were carried out between 17 and 20 July 1996 on the orange roughy spawning ground off St. Helens, Tasmania. A combination of 22 demersal trawls and ensonification with three frequencies (12, 38 and 120 kHz) was used to assess the species composition around the spawning hill....

The impact of changes in fishing patterns on red-legged banana prawns (Penaeus indicus) in the Joseph Bonaparte Gulf

The fishery for red-legged banana prawns in the Joseph Bonaparte Gulf (JBG) developed in the early 1980s. Since then, fishing effort has varied from 700 to 2600 boat-days per year and catches range from 200 to 1000 tonnes per year. Initially the JBG fishery developed as an alternative to fishing in...

Estimation of population parameters for Australian prawn fisheries

One of the main objectives of fisheries management is to ensure the sustainability of fished stocks. To reach this objective scientists have to adequately assess the status of fished populations with quantitative models of the fishery systems. Most of these models require estimates of population...
