Optimizing the nutrition of farmed Murray cod has several benefits. Tailoring bespoke feeds improves growth performance and feed efficiency, enhancing the economic viability of the sector. The project addresses gaps in Murray cod nutrition, focusing on large size classes, to identify areas for production efficiency improvements. Determining optimal macronutrient levels for extruded diets maximizes growth potential. Understanding the nutrient profile of feeds and its impact on fish performance guides feed selection and optimization. Through laboratory analyses, the project assesses the biometric and biochemical effects of the feed. Overall, optimizing Murray cod nutrition improves fish performance, feed efficiency, and contributes to sustainable growth in the sector.
