Developing indicators of recruitment and effective spawner stock levels in north Queensland east coast prawn stocks
Project number:

Principal Investigator:

SPECIES
In order to establish stock status, supply accurate advice and recommendations on management and monitor effectiveness of management intervention if need be, there is a need to develop procedures which
a) allow definition of the relationship between parent stock and recruitment levels in commercial prawn species, using fishery independant surveys as a means of determining recruitment levels
b) determine the status of these species and evaluate the potential risk of overfishing
c) develop methods which can used to evaluate the effectiveness of management intervention, if and when such intervention occurs.
1. To develop fishery independent sampling procedures that can be used as robust long term methods for monitoring recruitment levels in the tiger and endeavour prawn fisheries located along the northern Queensland east coast and in Torres Strait.
2. To obtain a series of (fishery dependent) indices of spawner biomass and (fishery independent) indices of recruitment which can be used to generate a long term data series.
3. Incorporation of the indices obtained in objective 2 into a stock - recruitment curve, an index of stock sustainability and an assessment of the risk of recruitment overfishing facing each of the species.

Developing indicators of recruitment and effective spawner stock levels in eastern king prawns
Project number:

SPECIES
The eastern king prawn is the Australian east coast's single most valuable fish species. On the basis of previous experience and existing data, the risk of overfishing this stock is unquantified but appreciable. Obtaining data which can be used to advise fisheries managers on the necessity of intervention can only be obtained from a focussed, directed multi agency study.
In order to establish stock status, supply accurate advice and recommendations on management and monitor effectiveness of management intervention if need be, there are needs to develop procedures which;
(a) allow definition of the relationship between parent stock and recruitment levels in eastern king prawns, using fishery independent surveys as a means of determining recruitment levels.
(b) determine the status of the species and evaluate the potential risk of over-fishing.
(c) develop methods which can be used to evaluate the effectiveness of management intervention, if and when such intervention occurs.
1. Develop procedures and protocols for measuring a fishery independent index of recruitment in eastern king prawns.
2. Develop a program designed to monitor long term recruitment levels and changes in recruitment levels of eastern king prawns.
3. Identify indices of effective spawning stock abundance for eastern king prawns in anticipation of the need for managing to increase spawner biomass.
4. Undertake preliminary investigations of larval and post larval eastern king prawns distribution and abundance as functions of depth, distance from shores and estuaries.

Risk analysis and sustainability indicators for prawn stocks in the Northern Prawn Fishery
This project has been highly successful at determining factors that affect the outputs and outcomes of the model and the uncertainty underlying the model system. The report has been divided into seven broad sections and two Appendices. The first chapter contains the context of the work;...

Definition of effective spawning stocks of commercial tiger prawns in the NPF and king prawns in the eastern king prawn fishery: behaviour of post-larval prawns
To effectively manage most fisheries, including penaeid prawn fisheries in northern and eastern Australia, it is important to know the relationship between the size of the spawning population and the number of young adults that recruit to a fishery in the next generation. In the tiger prawn fishery...

Designing, implementing and assessing an integrated monitoring program for the NPF: developing an application to stock assessment
For more than a decade the Northern Prawn Fishery assessments have indicated that the tiger prawn resource is overexploited. Deriso’s1 (2001) review of the tiger prawn assessment supported this conclusion and also drew attention to the high level of uncertainty in the assessment. Deriso...
