Fish growth

Fish is cold-blooded so its 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 fish well-being. The fish growth rate and feed utilisation efficiency can be effectively improved by breeding programmes Benefits of the breeding programmes are best achieved with selecting the feeding according to the prevailing circumstances.


Fish welfare

Fish welfare is crucial in terms of growth – healthy fish grow effectively. Farmed fish eat only aminoacid-balanced compound feed. In addition to proteins and energy, fish also get vital vitamins, trace elements and minerals from the feeds. Fish welfare can be supported in the sensitive development stages or under exceptional circumstances with various functional ingredients. In addition, well-being is secured with timely and quantitatively correct feeding.



In fish feeding, it is important to take the fish size and surrounding conditions into account. Raisioaqua has for long developed feeding recommendations for different fish species at different temperatures. These recommendations compiled as feeding tables help manage the feeding accurately and effectively. With the correct feed and feed amounts, fish growth is optimal and cost-effective with minimal environmental load.



Fish is a good source of vitamin D and omega-3 fatty acids. Through feeds 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 the correct fish feeding. Raisioaqua’s unique Opti feeding concept ensures high-quality, healthy end product on the consumer’s plate.
