Development of a fisheries R&D response to MPA and spatial management for fisheries

The governance arrangements for fisheries management are based on the use of spatial structures and management measures, such as jurisdictional boundaries, management plans and zoning of fishing type and intensity. These spatially-based arrangements are manifest at various scales and so there is a...

Development of methods to age commercially important dories and oreos

Four species of dories (Family: Zeidae) and five species of oreos (Family: Oreosomatidae) are caught in the South East Fishery (SEF). John dory and mirror dory are included in the SEF quota sytem with Total Allowable Catches (TACs), in 1993, of 240 t and 800 t, respectively. Oreos, originally a...

Need

Most fisheries in Australia are at sustainable levels or are overexploited. There is obviously a need to maximise yields from these resources. Consequently it is vital for fishery management to be able to discriminate between the effects of harvesting the resource versus the impacts of anthropogenic inputs on populations.

Funds are sought from FRDC to conduct a pilot program for developing methods of determining the impacts of chronic toxicity on fish eggs and larvae. This approach allows the measurement of the entire pollution load of an ecosystem. The successful application of this technique will allow fisheries managers to quantify the total toxicant loadings in habitats and to evaluate the potential impacts these toxicant loads have on fishery stocks.

The results of this Pilot study will have general applicability to temperate and subtropical systems. The usefulness of similar techniques to monitor ecosystem health has been demonstrated for tropical systems by Klumpp and von Westernhagen.

Objectives

1. Development methods for using imaging analysis as a tool for rapid and objective identification of fish eggs, teratogenic abnormalities and chromosome aberrations.
2. Evaluate the applicability of the "fish egg abnormality technique" for temperate species and evaluate its use in Port Phillip Bay.

Effects of Trawling Subprogram: maximising yield and reducing discards in the South East Trawl Fishery through gear development and evaluation

There is increasing worldwide concern about the ecological impacts of trawling. Reports of high levels of bycatch of fish and other species, habitat degradation, bad practices, stock depletion and perceptions of wastage and negative ecological impacts continue to fuel these concerns. ...
