However, in the quarter, we did sell more fresh fish and less frozen fish than in the quarter before. Revenue was up 28% over year- on- year. This of course results from the higher volume, but it was sold at a slightly lower revenue per kilo, although this was partly compensated by a favorable size mix, then if we look exactly at the price level, revenue per kilo in the quarter was EUR 14.30, down from one euro basically from a year before, but it was slightly higher than the second quarter of this year. Change in revenue per kilo reflects our increased promotional activity at the retail level, but also our efforts to open up more food service sales in areas where we believe our product has a lot of potential, going forward.
In the quarter, we continue to increase the proportion of large-sized fish in the sales mix, which now stands at 54%. We will work to continue to increase this number as we direct our efforts, to the food service segment, and we anticipate that over time the proportion of large-sized fish will exceed 70% of the sales mix. The increased proportion of large-sized fish will have a positive effect on margins. And with that, I hand over to Jean-Charles, who will comment on the financial results.
Thank you, Vincent. Good afternoon, everyone. So, on the financial front, this quarter has marked continued progress on our path to profitability. First, the external environment remains favorable. Our operations have benefited from lower feed price and improvements in feed formulation that support our profitability goals. There is still a lot of room for improvement with the feed formulation, and our progress so far has been quicker than we anticipated. Energy prices have remained stable, also slightly elevated, for this time of the year compared to the pattern we had the year before. In response, we've also launched an energy optimization project aiming at reducing the consumption in the farm and generating potential cost savings. So, our production cost per unit have increased this quarter due to two factors. First, the reduction of the production volume.
We are currently operating below the full capacity of the farm and with lower production volume compared to the previous quarter. Secondly, the biomass management, our actions to reduce biomass in the farm are temporarily impacting productivity and, as a result, increasing the production cost. This being said, this increase is temporary and does not reflect any shift in our ambition. We have both the resources and the proven track record to achieve our goal of reducing production cost towards EUR 7 per kilo. Then in Q3, we've invested in strengthening our sales and marketing infrastructure, and we are now we have a complete team in place. This is already yielding results. We see faster market penetration in the areas where the new team members are actively engaged.
So, this is very encouraging as we have now the means, in all the markets we have identified as strategic, to increase Yellowtail penetration. So, our EBITDA for the quarter is showing an improvement of EUR 0.70 per kilo compared to Q2 at minus EUR 0.90 per kilo. At the end of Q3, our liquidity position stands at EUR 15 million, down from EUR 18.5 million in June. We kept CapEx spending intentionally very low in Q3, and we will see an increase in Q4, especially as we have two projects in the execution phase. Working capital also has increased, including a EUR 1 million increase in inventory from biomass and frozen inventory. So, our strategy for profitability is based on increasing sales volume, achieving full farm utilization. This will create a virtuous circle, a sales increase, and we move closer to full utilization.
The revenue rise, production cost per unit decrease, and working capital needs will be optimized. So, we are aiming to reach EBITDA profitability breakeven by 2025, and we are optimistic about achieving positive cash flow from operation within a similar time frame. The key elements now are in place to support this goal. We have shown that our technology is robust, delivering very strong biological performance when the farm is efficiently managed. With our strengthened sales team, we have also a solid position to increase sales volume and to move towards full utilization. So, during this growth phase, we are closely monitoring our liquidity position while reinforcing also our financial discipline. So, we remain prepared to take prudent actions as needed to ensure we stay fully funded as we scale up.
So, I hand it back again to Vincent for the concluding remarks.
Thank you, Jean-Charles. So, just to conclude, I'd like to summarize the main takeaways from our Q3 results. First, our investment in sales and marketing are delivering tangible results. We've achieved a 37% increase in sales volume and a 28% increase in revenue. This underscores our success in deepening the market penetration and reaching out and reaching new growth areas. Secondly, we're taking significant steps in our operations, this time with the start of production of our next generation of fingerlings. Our breeding program, which started in fact 15 years ago, will continue to give us a competitive edge by producing juveniles and fish that will perform better and better every year.
Finally, we are on a path towards profitability, and we are well positioned to achieve EBITDA breakeven and positive cash flow from operations by 2025. This will be a major step forward in our financial trajectory and in our long-term growth strategy. Thank you for your attention and support as we continue our journey. We're looking forward to building on the results we have now and continue our growth trajectory in quarters to come. And we are now ready to take your questions. So, if you'd like to ask a question, please unmute, state your name and company, and go ahead. I am not seeing any questions. For sure, there are no questions.
Anybody?
Please feel free. Well, in that case, thank you very much, and see you in a couple of months in our next Q4 presentation. Thank you so much.
Thank you very much.
