Rock Lobster Post Harvest Subprogram: optimising water quality in rock lobster post-harvest processes

Rock lobsters can be exposed to poor water quality during all stages of handling and holding prior to going to market. Poor water quality reduces the time a lobster can be held alive and how many animals can be held in a system and thus may reduce profit. The quality of water can be assessed using...

Development of the tools for long term management of the giant crab resource: data collection methodology, stock assessment and harvest strategy evaluation

The project has developed tools for low cost assessment of the giant crab resource across southern Australia. Stock assessment and management response is now increasingly based on biomass estimates from this project. Risk of poor management decisions is thus reduced, which...

Need

As part of the activities of the FRDC 2008/306 Building Economic Capability in Fisheries Project an online survey of professional training needs in fisheries economics of 56 managers, industry representatives, and researchers within the seafood industry was conducted. Results of this survey indicate a high level of demand (100% of respondents) for short course training in fisheries economics. The highest level of interest was for a basic introductory course in fisheries economics of 1-2 days duration. Interest was also high in web-based modes of delivery.
Based on this feedback the initial round of Master Classes were developed in conjunction with the Seafood CRC. Results of the evaluation of these classes indicated that past participants will be recommending the class to others. The following organisations also expressed interest in dedicated Master Classes; AFMA; DPI Victoria; Dept. of Fisheries WA; and SA Rock Lobster Advisory Council (SARLAC) and could be approached individually to ascertain possible enrolments.

Ongoing demand for such training opportunities was also highlighted in the review of the project undertaken by Ian Cartwright as part of the Legacy from Future Harvest review, where it was concluded the initial offering be revised and extended. This work was initially presented and approved as an extension to Seafood CRC Project 2010-714 ‘The Future Harvest Master Class’ but subsequently has required a separate project application.

Objectives

1. To revise/extend the existing face-to-face Masterclass materials/resources
2. To develop an online version of the Masterclass
3. To develop a strategy for marketing, delivery and funding of the Masterclass

Can commercial harvest of long-spined sea urchins reduce the impact of urchin grazing on abalone and lobster fisheries?

At low-levels of exploitation, commercial harvesting of long-spined sea urchins was found to prevent increase in urchin density. Adjacent unfished locations experienced an increase in both urchin density and grazed area over the 2014 – 2016 study period. Research sampling of populations...

Need

Fisheries resources are managed for biological, economic and social purposes or objectives. Recommendations made at the Advisory Committee (MACs and FACs) level have significant economic implications for key stakeholders and for the wider community who have an interest in the returns gained from resource utility.

The current low level of understanding of fisheries resource economics amongst those in decision-making roles precludes the capacity to integrate economic parameters and indicators into assessment and decision-making processes. This generates lost opportunity in current management and is a barrier to the development of economic targets for fisheries and the selection of optimal fisheries management & harvest systems.

A recently completed FRDC report, ‘Evaluating the Performance of Australian Marine Capture Fisheries’ (2009), examined the performance of Australian marine capture fisheries and found a massive gap between actual and potential performance. The same project identified the need for more strategic management as the highest priority in closing this gap, which is targeted through this project.

Increasing the understanding of fisheries resource economics amongst members of MACs and FACs is therefore considered necessary to assist the uptake of management tools that would enhance the economic performance of wild-catch fisheries (AFMA, 2007: Economics in Commonwealth fisheries management - Workshop final report, 2 March 2007, Canberra). Most significantly, increasing the understanding of fisheries resource economics principles will support the achievement of Future Harvest outcomes.

The target audiences for the Future Harvest Master Class includes fisheries managers, advising fisheries biologists, & industry representatives associated with key CRC partner investors in the Future Harvest business theme. Specificially, the Master Classes will be offered to members of those MACs or FACs which advise on those fisheries of interest to the key CRC partner investors.

Rock Lobster Post Harvest Subprogram: quantification of shell hardness in southern rock lobster

Project number: 2002-238
Project Status:

A new, simple and quick solution to the ambiguity of current measures of shell wear is to quantify shell hardness with a durometer, which is a small, hand-held device originally designed to measure the flexibility of plastic sheeting (Hicks and Johnson, 1999). This system of standardisation has recently been introduced in Alaskan crab fisheries. Before these devices can be used for Australian rock lobster stock-assessment, a series of short experiments are needed to calibrate hardness reading to the moult cycle. These experiments will allow future research sampling to record more useful measures of moult stage and thus provide more effective stock assessment.

This calibration will have immediate application in Tasmanian research for assessing the effect of September and November harvests on mortality of discarded lobsters. Processors in both South Australia and Tasmania anticipate that this project will provide a valuable tool for industry to use in setting acceptable levels of shell hardness for the landing of export-grade lobsters. That is, fishers will be able to establish a quantitative shell hardness grade that a processor will accept prior to landing the catch. This eliminates the current problem of the landing of lobsters that are ambiguously classed as “hard” by a fisher but “soft” by a processor – with resultant negative impacts on economic yield and markets.

Objectives

1. To calibrate the rate of change in shell hardness before and after the moult of southern rock lobsters relative to lobster size, sex, region and temperature.
2. To identify the region of the exoskeleton that is most suited for measuring hardness.
3. To develop a prototype gauge for industry use that can be used to measure shell hardness of lobster with precision in industry conditions.
