Fish are cold-blooded, so their growth depends on environmental conditions, such as water temperature and oxygen levels. In food fish production, the aim is to grow fish quickly, minimise environmental load and ensure the welfare of the fish. The growth rate and feed utilisation efficiency of fish can be effectively improved through selective breeding. The benefits of selective breeding are best realised by selecting the feed and feeding according to the prevailing circumstances.
Fish welfare is crucial for growth – healthy fish grow effectively. Farmed fish eat only compound feed with balanced amino acids. In addition to protein and energy, the feed also provides fish with essential vitamins, minerals and trace elements. Various functional ingredients can be used to support fish welfare during sensitive developmental stages or in abnormal conditions. Welfare is also ensured by timely and quantitatively correct feeding.
In fish feeding, it is important to take the fish size and surrounding conditions into account. Raisioaqua has long been developing feeding recommendations for different fish species at different temperatures. These recommendations, compiled into feeding tables, help farmers manage the feeding accurately and efficiently. With the right feed and feed amounts, fish grow optimally, cost-effectively and with minimal environmental impact.
Fish is a good source of vitamin D and omega-3 fatty acids. Through feed and feeding, Raisioaqua strongly invests in the nutritional healthiness of the end product, i.e. farmed fish. The best possible healthiness can only be achieved with correct feeding. The unique Opti feeding concept developed by Raisioaqua guarantees that the consumer receives a high-quality and healthy end product.
