The so called pragmatic approach to the welfare of aquatic animals (Arlinghaus et al. 2007) measures welfare status using a variety of well-established, un-controversial physiological and functional parameters (Rose et al. 2014, Browman et al. 2019). For example, all finfish, crustaceans and cephalopods can experience stress, which can lead to poor welfare outcomes (Rose et al. 2014). From an animal welfare perspective, the overall aim to maximise fish welfare during capture is to minimise stress within the constraint of practices inherent to the relevant fishing sector (Mazur and Bodsworth 2022).
Using this pragmatic approach, the Aquatic Animal Welfare Working Group (AAWWG) which was formed under the Australian Animal Welfare Strategy (AAWS, 2005-2014), developed a range of Overarching Welfare Principles which related to finfish harvested from the wild in commercial fishing industries.
Out of the eight Overarching Principles developed by the AAWWG, as pointed out by Mazur and Bodsworth (2022) the three that are most relevant to the commercial wild harvest industry are:
1. Timely handling from capture to death is essential to minimise stress;
2. Capture methods should be designed to minimise the capture of unwanted species
3. Any fish selected for harvest should be killed as rapidly as possible, by humane means suitable for the species.
To address the legislative issues under the new Act, meet current and future fish welfare challenges, and maintain their social license to fish, commercial fishers targeting sharks in the NT need to develop workable and effective standards for handling and dispatching sharks which can be recognised and prescribed under the new Regulations.
Since shark fisheries are specialist fisheries which were not covered by the AAWWG during the AAWS, there is a need to develop specific resources to assist the industry with humane dispatch of sharks.
Science shows that brain destruction by pithing or “iki-jime” is the fastest way to dispatch finfish, resulting in the lowest levels of stress and maximising the quality and shelf life of the resulting fish product (Poli et al. 2005, Diggles 2015). However, the brains of sharks are small and vary in location between species, which is why this project is being proposed and is necessary to determine the brain location of the sharks most commonly captured in the NT shark fishery, and then examine various methods of rapidly destroying the brain, in order to develop guidelines and best practice protocols for their humane dispatch. Importantly, it should be noted that this is an industry driven project.

FRDC recently co-funded a cross-commodity project on Designing the integration of extension into research project (James, 2022), which sought to improve adoption of outcomes from RD&E project. At the conclusion of this report, recommendations for Phase 2 were made, and these included several focused on developing and trailing different learning approaches for knowledge transfer. Understanding learning approaches required for different topics and cohorts is an essential next step to improve practical outcomes associated with development, change, and adoption processes. This project represents an opportunity for FRDC to build on this initial investment and generate new knowledge on the connection between learning approaches and knowledge transfer to enhance the fisheries and aquaculture sector’s capability and capacity for adaptability and change.

A systematic review of the literature on the topics of adult learning, knowledge transfer, and transformational change will identify and evaluate relevant findings for the fisheries and aquaculture sector. These will be further ground-truthed through extensive stakeholder consultation within (a) wild catch organisations, (b) aquaculture organisations, and (c) through the wider industry knowledge network (e.g. extension officers and research teams). A compilation of informal and formal learning and development opportunities in fishing and aquaculture within organisations and in the wider industry will be analysed, and case studies of best practice identified, analysed and showcased as examples of successful change, adoption, skill development and shift in mindset.

These evidence-based context-specific insights will be translated into a guide, tool or micro-credential for best practice in designing and delivering knowledge transfer and practice change activities. The usefulness and ease of use of this resource will be tested in a workshop with FRDC extension professionals and other interested stakeholders, refined and then introduced to the fisheries and aquaculture community for application to learning and training in organisations and throughout the wider industry. It is expected that the findings of this project will have implications for the project Capability and capacity: Navigating leadership pathways in fishing in aquaculture, in particular insights on how learning approaches for the topic area of non-technical skills development (e.g. communication, team effectiveness, career self-management, problem-solving, strategic thinking and foresight) occur within organisations that may prove to be the start of the leadership pathway for people within fisheries and aquaculture, and if done effectively may widen and diversity the talent pipeline into mid to high leadership level development opportunities.

This project has been designed with a 12-month timeline, with options to scale down if required by FRDC.
