Integrating recreational fishing information into harvest strategies for multi-sector fisheries

This interim report provides an update on workshops with recreational fishers, scientists and managers to investigate recreational fishing objectives for three stocks of recreational importance in NSW – Mulloway, Yellowtail Kingfish, and Snapper. The study forms part of a broader research...

An assessment of the impact of offshore recreational fishing in NSW waters on the management of commercial fisheries

Conflict between the recreational and commercial sectors has long been a fisheries management problem. This conflict has been escalating in recent years as both sectors attempt to maximise catches. Consequently, there is increasing pressure being applied to fisheries managers to make appropriate...

Need

There is a need to synthesize all existing information and to obtain new basic biological and fisheries-related information on mulloway to be able to make informed management decisions concerning the continued sustainable harvesting of the species in NSW waters and elsewhere and to arrest the apparent decline in populations. Most importantly, the growth and age and reproductive biology of mulloway needs to be accurately described and data on the length, sex and age compositions of catches and how these vary between different fishing sectors and gear types needs to be collected and analyzed to provide us with even the most basic understanding of the potential effects of fishing on this very important species. Yield-per-recruit analyses need to be done to aid discussions on appropriate legal lengths.

Objectives

1. Synthesize, write and publish a review of the biology and fisheries of mulloway (and other relevant sciaenid species) in an international scientific journal and provide a layman’s summary that can be given to stakeholders.
2. Reanalyze all existing tagging information on mulloway.
3. Describe the growth and age and reproductive biology of mulloway in NSW and do yield-per-recruit analyses.
4. Determine the length, sex and age compositions of commercial catches of mulloway and assess how these vary between different gear types, industry sectors (e.g. estuary v ocean) and regionally.
5. Advise the commercial and recreational fishing communities and other interest groups on the biology of mulloway and provide recommendations on ways to stop the apparent decline in populations and future management and assessment strategies for the species.

Effects of Trawling Subprogram: the interaction between fish trawling and other commercial and recreational fisheries

There is worldwide concern over the potential effects of by-catch and discarding of fish in commercial fisheries, particularly trawling. Although mortalities of discards are highly variable, it is likely that a large proportion of fish discarded at sea by trawlers do not survive. Consequently,...
