Development and implementation of a national standard for a recreational fisheries database by all fisheries agencies

SIRFIS is and acronym for Standardised Integrated Recreational Fisheries Information System. The system is designed to provide a user friendly and flexible environment in which to enter, store and retrieve data relating to recreational fisheries. The system also allows storage of comprehensive...

Developing jungle perch fingerling production to improve fishing opportunities

This project has for the first time demonstrated the feasibility of hatchery production of jungle perch fingerlings. The research on jungle perch production has enabled a hatchery production manual with accompanying videos to be produced. This has given private commercial hatcheries the information...

Freshwater fish attracting structures (FAS): Evaluating a new tool to improve fishing quality and access to fisheries resources in Australian impoundments

This document has been compiled from various sources and, to the authors’ knowledge, represents the best advice currently available regarding the use of fish attracting structures to improve recreational angling in Australian impoundments. Although the principles outlined in this document may...

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.

Improving bycatch reduction strategies and escape vents in Queensland Mud Crab fisheries

The Queensland Crab Fishery is an iconic fishery, which encompasses the harvest of mud crabs (Scylla serrata, the Giant Mud Crab, and Scylla olivacea, the Orange Mud Crab) and Blue Swimmer Crabs (Portunus armatus and Portunus pelagicus), predominately using baited crab pots of various designs. The...
