Optimising the nutrition of farmed Murray Cod

Funded Activity Summary

The consistent growth of the Murray cod production sector in Australia is evidence that the industry is no longer fledgling and has grown into a significant production sector. Growth figures from 2012 until now effectively doubled year on year, with the total production from 2019/2020 season estimated to be around 516 tonnes with an industry value of around $9.2 million (AUD). With this increased production and forecast to reach a $50 million dollar sector by 2030, it is imperative that feeds for Murray cod are tailored and bespoke to reach their full potential. The development of bespoke feeds for the sector will have the added benefit of improving the economics of operations from both a growth performance and feed efficiency perspective.

Noting that past research on Murray cod primarily by researchers at the Deakin University was very successful in demonstrating some core aspects of fish nutrition, it remains to be determined what benefits are possible on larger fish size classes which represent the bulk of feed consumed. In other well studied species such as Atlantic salmon and barramundi, gains in production efficiency can be achieved by diet design, with incremental changes improving the profitability throughout the life cycle. Although there is no co-op or association for growers, a recently commissioned report has highlighted the need for improved feeds and key R&D support for the sector is required. The proposed project aims to address some of the fundamental gaps in Murray cod nutrition on large size classes to identify where gains in production efficiency can realistically be achieved.

Objectives:
1. Determine a baseline for the most optimal macronutrient levels (principally protein and lipid) for medium and large Murray cod in extruded diets.
2. Understand the nutrient profile of the feed types and how this affects the fish performance.
3. Conduct a series of laboratory analyses to determine the biometric and biochemical effect of the feed.
