Need

The project will review and synthesise available global data on the potential effects and implications that plastic is causing in seafood species in the context of the impacts they generate to fishing and aquaculture sectors. Concurrently, using published literature on sources of marine pollution, the abundance of plastic entering aquatic systems from seafood related sources will be quantified, with particular focus to the Australian context. Ultimately, this will give the fisheries sector, particularly in an Australian setting, the knowledge to evaluate where appropriate mitigation strategies are necessary and reduce the presence and impacts of microplastics in seafood.

This project aligns with FRDC R&D Plan Outcome 1: Growth and Enduring prosperity; In particular, it targets the priorities of:
- Improving the understanding of the cause and extent of impacts to aquatic systems and what is needed to improve them
- Promote a circular economy to remove waste from the processing system, keep products and materials in use and promote the repair of natural systems

Providing information on how marine pollution may affect the seafood industry and seafood species fished will guide the urgency of future research and allow management and mitigation strategies that support the seafood sector to be developed. Ultimately, quantifying the amount of plastic contributed by the seafood sector to marine plastics will allow us to advance with solutions and uncover where plastic alternatives are most needed.

Objectives

1. Undertake a systematic review, collating, synthesising and analysing global data on the effects and implications of plastic pollution in seafood species and the seafood industry
2. Identify potential sources of plastic in marine environments, including the percentage coming through fishing and aquaculture
3. Highlight key knowledge gaps, opportunities and threats of plastic in the seafood sector
4. Disseminate findings and information on effects and implications of plastic pollution on seafood species to fishers and managers

Summary

Microplastics are commonly consumed by seafood species however, there is still limited understanding of the effects and implications that microplastics may have on the fishing and aquaculture industry. This project summarises research on the effects that microplastic may be having on seafood species and the contribution that the seafood industry is having to marine plastic pollution. Global literature on microplastic effects in seafood species revealed 1) that 93% of all species were negatively affected by plastics, although many studies used increased levels of microplastic contamination that are not environmentally relevant (i.e., generally do not reflect environmental conditions); and 2) 23% of plastic pollution in the marine and coastal environment originates from fishing and aquaculture sources. This
report provides clear-sighted recommendations on the threats and opportunities that plastics hold for the seafood sector, as well as avenues for potential mitigation and reduction.

Tropical fish traps – addressing ghost fishing impacts and refinements to catch reporting/sampling

Project number: 2022-164

Need

The negative impacts of lost fish traps ghost fishing are well documented and of concern to all parties involved with the sustainable harvest of seafood from the aquatic environment (Macfadyen et al 2009; Newman et al 2011; Vadziutsina & Rodrigo 2020). Essentially, lost fishing gears that continue to kill/harm fish represent an inefficiency in the fish production process, and in essence are a form of waste associated with the harvesting process, that ultimately reduces the yield and casts a bad light on the fishery itself. This project does not meet any specific FRDC priority in the current round, hence the lodgment under (Other), although because of what it attempts to address and minimise, it is likely to gain strong support from those concerned with appropriate management of fisheries i.e., minimising the wasteful use of renewable food resources at a time when there is a food crisis in the world, with parties including the FRDC, AFMA, ENGO's and the fishing industry.

Objectives

1. Quantification of fish trap (various designs) loss rates, both in the distant past and more recently, together with the main factors influencing the loss rate.
2. Quantification of how well “dumped” or unattended traps catch fish, together with the main factors affecting the performance (including the presence of trap disabling mechanisms).
3. Apply refinements* to fishing practices/gear to address loss rates and ghost fishing and assess performance (*utilising observations made in the first year of project).
4. Apply refinements to fishing activity reporting to assist with the management of effort creep, trap loss, and ascertaining appropriate harvest levels for the target species.

Evaluation of practical technologies for Perfluoroalkyl (PFA) remediation in marine fish hatcheries

Per- and poly-fluoroalkly substances (PFASs) are now emerging as pollutants with potentially catastrophic impact on aquaculture facilities. Two key research institutes, Port Stephens Fisheries Institute (PSFI) in NSW and Australian Centre for Applied Aquaculture Research (ACAAR) in Western Australia...

Future oysters CRC-P: Polymicrobial involvement in OsHV outbreaks (and other diseases)

The principal goal of this research was to provide a detailed characterisation of the oyster microbiome and identify links between specific features of the microbiome and oyster disease and mortality events. The conceptual framework for this work is based upon: (i) increasing...
