This project aims to secure sustainable chicken-meat production by the radical reduction or even elimination of imported soybean meal as the primary protein source in Australian broiler diets by its replacement with feed-grade amino acids and local feedstuffs. This project will expand our comprehension of starch/glucose and protein/amino acid digestive dynamics in poultry diets based on wheat, the primary feed grain in Australia; however, wheat does inherently possess nutritional disadvantages. Expected outcomes include soybean meal-free feed formulations for the Australian chicken-meat industry to enhance the affordable and environmentally viable production of chicken-meat coupled with improved bird welfare and flock health.

Aquaculture is the fastest growing livestock industry in Australia, and is expected to double in value to $2 billion by 2027 to meet global seafood demand (National Aquaculture Strategic Plan). Therefore access to safe and effective veterinary medicines is critically import to support the current industry and its expansion.
Australia’s aquaculture industry must have access to safe and effective veterinary medicines for disease management, industry productivity and animal welfare. This need is highlighted in Australia’s national strategic plan (www.agriculture.gov.au/animal/aquatic/aquaplan) and FRDC’s strategic plan (2015-2020 and 2020-2025) including supporting the future sustainable expansion of aquaculture.
Veterinary medicines are required for prevention (for example, vaccines), therapeutic treatments (for example, antibiotics, anthelmintics and antimycotics) and husbandry (for example, hormones for reproduction and anaesthetics for animal handling). Currently there is a substantial lack of access to permitted or registered products.
There is a clear need for national coordination of applications for permits and registrations for aquatic veterinary medicines that replaces the duplication, disjointed efforts, poor permit applications and restrictive minor use permits and generally wasted resources occurring in the seafood industry.
There is a need to coordinate seafood industry prioritisation and application for access and use of agvet chemicals and to establish effective relationships between the seafood industry and APVMA to progress this important issue.
A model to support the resourcing of this service to industry and regulators needs to be devised to maintain this activity after completion of this project. Objectives: 1. Document a safe and effective process for the off-label use of veterinary medicines aimed at supporting fish health, welfare and production while managing environmental risks and enabling data generation. 2. Coordinate a national effort to facilitate the progress of priority aquatic veterinary medicines in the seafood industry through to permitting or registration with the APVMA 3. Determine options for a system, framework and / or business case to effectively coordinate national data generation and applications to the APVMA into the future, and maintain current permits and registrations in the seafood industry. 4. Develop and implement a communication and awareness strategy for industry on safe and effective veterinary medicine use Read moreRead less

Summary
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).

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.

Summary
Skates (Rajidae) represent the greatest biomass of incidental bycatch caught in the Patagonian toothfish (Dissostichus eleginoides) longline fishery operating within Australian EEZ waters around HIMI in the Southern Ocean. Due to their life history characteristics of slow growth and late maturation, their populations are particularly vulnerable to fishing mortality which can lead to overall and localised population declines.

Due to their life history characteristics of slow growth and late maturation, their populations are particularly vulnerable to fishing mortality which can lead to overall and localised population declines. As bycatch managed species, sustainable bycatch limits are informed by a stock assessment (using the Generalised Yield Model) which models long-term population viability. Such models can be sensitive to the input parameters of assumed total fishing mortality. Currently, in the HIMI fisheries, only retained skates are counted towards fishery removals, but the overall fisheries-induced mortality may be substantially higher due to the high number of skates released after capture and the unknown, but potentially low, post-release survival. Post-release survival becomes increasingly important as the scale of discarding increases; with ~90% of all skate bycatch in the HIMI longline fishery being released it is imperative that post-release survival is quantified to get an accurate estimate of total fishing mortality.
This project aims to quantify post-release survival of Bathyraja spp. skates caught in the deep waters of the Kerguelen Plateau using the latest in pop-up satellite tag technology. In doing so, this project will improve the estimation of total fishing mortality to inform the skate bycatch assessment model and the estimation sustainable yield. Thus, it supports the Commonwealth Research Advisory Committee 2018-2021 Research Development and Extension (RD&E) Plan by addressing the following priority area actions: Program 1. Environment • Better Assessment Approaches, and Harvest and Management Strategies o By quantifying post-release survival we provide a demonstrable improvement in fisheries removals data quality and decision-making by providing evidence-based recommendations for setting accurate bycatch limits. • Better Managed Fishing Impacts and Interactions o By underpinning accurate bycatch limits with accurate long-term population viability estimates we enable fisheries managers to demonstrate environmentally sustainable bycatch management practices.
In addition to the COMRAC RD&E Plan, this project addresses the following priority area outcomes within the Southern Ocean Industry Partner Agreement RD&E Plan: Program 1. Environment • TEP and bycatch management: o The need to monitor skate/ray bycatch by providing accurate estimates of total predicted fishing mortality based on past and current catches. o Develop stock assessment approaches for skate bycatch species (which are generally not retained for commercial use) by integrating quantified fishing mortality estimates into the stock assessment model. o Provide post-release survival estimates and insight into behavioural ecology of deep-water skates for development of a risk assessment for multiple incidental bycatch species. Program 2. Industry • Management efficiency o By resolving a key component of uncertainty in the stock assessment this project reduces risk in fisheries management decision-making processes by improving accuracy in bycatch limit recommendations.
Furthermore, this project meets the primary objectives of the AFMA Strategic Research Plan (2017-2022), namely to collect appropriate information to support stock assessments, support the management of Commonwealth fisheries, and inform policy development [Research Strategy 1a]. The results of this study will also inform fisheries managers on appropriate specifications for the release and retention of caught skates. Objectives: 1. Quantify immediate (2 days) and long-term (60 days) post-release survival rates for longline caught B. irrasa across shallow (~500m) and deep (~1500m) depth strata. 2. Characterize post-release activity patterns of B. irrasa during the descent and bottom periods to understand effects of capture related physiological stress. 3. Validate whether stress markers (e.g., magnesium, potassium, lactate) measured in the blood of B. irrasa at the time of capture may be indicative of whole-animal physiological condition and may be used as predictors of post-release survival.
