Fisheries biology and interaction in the northern Australian small mackerel fishery

The small mackerels comprising school mackerel (Scomberomorus queenslandicus), spotted mackerel (S. munroi) and grey mackerel (S. semifasciatus) are important and valued species to recreational and commercial fishers in northern Australia. Prior to this project very little was known about the basic...

A study of seagrass prawn nursery grounds and juvenile prawn populations in north Queensland

Seagrasses are of immense ecological importance in marine ecosystems. Primary production rates for seagrass beds are amongst the highest recorded for marine and terrestrial systems. They have a well documented role as animal habitat, nursery grounds, and as substrate stabilizers. The proximity of...

Need

There is a critical need for information to support management decisions about inshore fisheries resources, and to address rising industry, conservation and public concern about the impact of net fishing on sustainability and biodiversity of the ecosystem and habitats associated with the fishery. The theory of measuring changes in biodiversity have yet to be applied in net fisheries. This project will be a test case for the practical application of determining net fishing effects on biodiversity.

Information on the effect of net fishing on bycatch and biodiversity in Australia is extremely limited. While some data exist on the marketed catch, the quantity and nature of bycatch remains virtually unknown. There is little information on the total catch characteristics of net fisheries, the proportions of species caught, and the proportion of the resource harvested each year. Similarly little is known about the fate of fish discarded from nets which would help to characterise the impact of net fishing on biodiversity.

This project will address the urgent need for information on the: total catch composition from net fishing, fate of discarded fish bycatch, impact on protected species and impact on biodiversity. Baseline data collected through both fishery dependent and independent methods will provide a basis for long term monitoring of the fishery and will enhance the interpretation of existing commercial catch records. These data will help meet the requirements of the ‘National Strategy for Conservation of Australia’s Biological Biodiversity’ of a) improving the knowledge base of fisheries, b) improving fisheries management and c) assessing and minimising the impact of commercial fishery practices on non-target and bycatch species, ecosystems and genetic diversity.

Objectives

1. Establish proportions of target catch and bycatch caught in inshore net fisheries along the Queensland east coast and the Gulf of Carpentaria.
2. Characterise the bycatch component of net fisheries in terms of species composition, seasonal abundance, habitat type and mesh size.
3. Determine the fate of fish discarded from net catches.
4. Establish the effects of net fishing on biodiversity through intensive comparative studies of areas closed and open to commercial net fishing.
5. Provide management advice on possible sustainability and biodiversity indicators, and on changes in net fishing practices needed to reduce impacts on bycatch species and biodiversity.

QFISH Foresight Project - a strategic planning and futuring project designed to create a strong coordinated commitment by all stakeholders to an agreed vision of the fisheries of the future

The establishment in 1997of the Fishing Industry Development Council (FIDC), a peak fishing advisory body, set the scene for an examination of where Queensland’s fisheries and the fishing industry sectors were heading in the longer term. The FIDC is a high level consultative forum...
