In Japan, some fish farms have adopted an interesting technique called "Musical Fish Culture." After the eggs hatch, juvenile fish are exposed to music during feeding times. This helps them associate the sound of music with mealtime, encouraging them to gather at the feeding area. As the fish grow and are moved to larger ponds, the same music is played during each feeding session, reinforcing their habit and making the process more efficient.
Another innovative approach comes from Moscow Agricultural University, where they use a temperature adjustment method to boost fish growth. By installing a heater in the nursery pond, they raise the water temperature by 2-5°C above normal levels. This slight increase not only speeds up the growth of fry but also improves their ability to adapt to different temperatures, which reduces mortality rates by 2% to 3%.
In the United States, a leading aquaculture company has developed a unique fish-breeding method known as the "Fish-Fish Method." Through selective breeding over eight years, they have successfully produced a spineless fish species. This special variety has only one spine, and its internal bones have completely degenerated, making it easier to eat and more appealing to consumers.
Additionally, the Western British Fisheries Experimental Station uses a fat-feeding method to improve fish health. They add 4% to 8% fat—either animal or plant-based—to semi-refined feed given to fry. This dietary enhancement significantly lowers the mortality rate among young fish, contributing to healthier and more robust fish populations.
These techniques highlight how modern aquaculture is constantly evolving, combining science, technology, and creativity to enhance fish growth, survival, and quality.
Magnetostrictive System Scaler
A magnetostrictive system scaler is a dental instrument used for removing calculus and plaque from the teeth. It utilizes high-frequency vibrations generated by a magnetostrictive transducer to break down and remove the deposits from the tooth surface.
