1) Legal obligation.
In Australia, sea snakes are a protected species group under Schedule 1 of the National Parks and Wildlife Regulations 1994, but despite their protected status, tens of thousands of snakes are caught incidentally in the Queensland trawl fishery each year. In the Northern Prawn Fishery (NPF) it has been estimated that between 81,000 and 120,000 were caught annually in the early 1990s (see Wassenberg et al. 1994 and Ward 1996). Wassenberg et al. (2001) reported that 48.5% of sea snakes caught from research and commercial prawn trawling die as a result of being trawled. The Queensland Government and the Queensland commercial trawl fishers are legally obliged to address the problem and minimise sea snake – trawl interactions.
2) Recommendations by the Department of Environment and Heritage (DEH)
The impact of prawn trawling on the sustainability of sea snake populations on the Queensland east coast is a major concern to DEH. In their review of the strategic assessment of the Queensland east coast trawl fishery, DEH recommended to the Queensland Government that research into the impact of trawling on sea snakes be promoted, and that all reasonable steps should be undertaken to reduce interactions between protected species and the Queensland trawl fishery.
In summary there is a strong legal case in support of research that reduces the impacts of trawling on sea snake populations. In addition, addressing the DEH recommendations will help to ensure that that the Queensland east coast trawl fishery remains on the list of fisheries that are accredited for export, thus securing the continuation of the export of seafood produced from the fishery.

1. Collate and review existing data and literature on sea snake distribution and abundance on the Queensland east coast. This will enhance the detail and precision of the recently introduced CFISH logbook data program on Species of Conservation Interest.
2. Implement a crew-based data collection program to quantify information on sea snake catch rates, species composition and distribution. Where possible, consider areas that are closed and open to trawling (contingent upon GBRMPA approval to sample closed areas).
3. Quantify post-trawling mortality rates of sea snakes by undertaking survival experiments at sea on commercial vessels.
4. Test effectiveness of BRDs, including square mesh panels, on sea snake catch rates and promote the uptake of effective devices by industry.

Assessment of Queensland inshore net fisheries
Most of the world’s marine fish harvest still comes from coastal waters despite the rapid development of distant water fishing fleets (McHugh, 1967). Fish yields from estuaries and lagoons are generally high, due to factors including shallowness, inflow of nutrients from rivers, and the...

Population dynamics and management of spanner crabs in southern Queensland
Spanner crabs (Ranina ranina) represent a valuable resource to southern Queensland and northern NSW. The fishery became established in the late 1970s, and as a result of an almost exponential increase in fishing effort between 1992 and 1995 an output-controlled limited entry management arrangement...

Seafood CRC: harvest strategy evaluations and co-management for the Moreton Bay trawl fishery
The Moreton Bay otter trawl fishery is a multispecies fishery, with the majority of the catch composed of various species of prawns, squid and Moreton Bay Bugs. The project was an initiative of the MBSIA and developed from concerns over a number of issues. These included concern over declining...

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...
