Future proofing the northern Australia aquaculture industry need for skilled staff to 2050

The aquaculture industry in Northern Australia (NA) is undergoing a period of unprecedented growth, precipitating an increasing demand for skilled staff. To facilitate this growth, the industry requires an increasing stream of suitably skilled and qualified entrants to the industry workforce. Prior...

A Better Way to Fish: testing the feasibility of tunnel net ‘fish trap’ gear in North Queensland

This study found that tunnel nets are technically feasible in this location. In spite of the weather conditions, the fishing gear remained intact and successfully captured significant numbers of marketable fishes. Importantly, SOCI species were released alive and in excellent condition, as were...

Effects of climate change and habitat degradation on Coral Trout

Fishes are at considerable risk from changing environmental conditions because they are, for most part, unable to regulate their body temperature. Exposure to high temperatures may therefore compromise critical biological functions, resulting in reduced performance, fitness and ultimately survival....

Testing established methods of early prediction of genetic merit in abalone broodstock

This report provides an assessment of the utility of RNA/DNA ratio as a method for early prediction of high performing abalone broodstock. The study was carried out on farmed Greenlip Abalone (Haliotis laevigata) whereby families were produced and resulting progeny were reared using commercial...

Real time monitoring of water quality and mechanisation of pond management to boost productivity and increase profit

Maintenance of adequate levels of dissolved oxygen (DO) are critical for the health and production of aquaculture species. In barramundi (Lates calcarifer) pond aquaculture the use of 24 hr/7 day mechanical aeration via paddlewheels represents a significant energy cost to companies,...

Need

The omega‐3 long‐chain polyunsaturated fatty acids (n‐3 LC‐PUFA) and minerals are essential nutrients to the health of humans are a major contributors that fish makes to the human diet. Consumers are increasingly aware of the nutritional requirement for n‐3 LC‐PUFA and are therefore seeking products high in n‐3 LC‐PUFA such as Atlantic salmon and fish oil capsules.

Barramundi has high oil and n‐3 LC‐PUFA. Based on samples collected in 2010, the absolute content of n‐3 LC‐PUFA of farmed barramundi was similar to that of Atlantic salmon and four times greater than that of wild barramundi (Nichols et al., 2014). Not only did this information fail to reach food agencies or health organizations but some such as the Australia Heart Foundation (NHFA, 2015) continue to use information generated 15 years ago to categorize farmed barramundi as of inferior quality to farmed salmon or other market competitor species such as Australian snapper. Similarly, the National Health and Medical Research Council (NHMRC, 2017) encourages fish consumption as a major supplier of iron, zinc, iodine, calcium and magnesium to the human diet. However, the mineral content in fillet of fish is poorly documented, differs across species and culture conditions (Antony Jesu Prabhu et al., 2016), and has not been documented for barramundi.

This project will examine the variability in the nutritional value of Australian farmed barramundi and will categorize it in relation to other fish products available to the Australian consumer.

The ABFA will then use the findings as part of their marketing program to sell the nutritional benefits of Australian farmed barramundi to consumers and relevant food agencies.

Objectives

1. To assess the variability in nutrient composition, specifically omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) and minerals, in the fillet of farmed Australian barramundi (Lates calcarifer).

Summary

Farmed Australian barramundi (Lates calcarifer) is a reasonably well-recognised fish product in the Australian marketplace, however, its nutritional value and health benefits compared to other animal protein and seafoods is not quantified and widely known by consumers. This study assessed the nutrient composition, specifically omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) and minerals, in farmed barramundi fillets so that updated nutritional information could be provided to food agencies and to identify potential marketing advantages. Australian farmed barramundi were sourced from seven farms across three fish sizes (0.6 kg, 1.5 kg and 3 kg), between seasons (winter and summer) and from different production systems (low vs high salinities). To compare omega-3 levels in Australian farmed barramundi with other consumer fish products, wild caught Australian and imported barramundi, as well as Atlantic salmon (Salmo salar), tropical snapper (Lutjanus spp.), Nile perch (Lates niloticus) and Basa catfish (Pangasius spp.), were included in lipid, fatty acid and mineral analyses. Tasmanian farmed Atlantic salmon had higher levels (three-fold) of n-3 LC-PUFA than Australian farmed barramundi.
Levels of n-3 LC-PUFA in Australian farmed barramundi were similar to wild barramundi and saddletail and goldband snapper. However, Australian farmed barramundi had significantly higher levels of n-3 LC-PUFA than imported white flesh fish alternatives Nile perch (three-fold) and Basa (16-fold). One serving (150 g) of Australian farmed barramundi fulfils one person’s daily n-3 LC-PUFA and selenium requirements, respectively. There was little difference in the nutritional composition of imported and Australian farmed barramundi.
These findings can be used in conjunction with marketing programmes that are focused on the nutritional benefits of Australian farmed barramundi to consumers and associated food agencies.
