The History of Filtration in Fish Farming
The concept of breeding and raising halibut in tanks makes sense, but there have been numerous challenges throughout history that have led us to the modern solutions of today. Before the first aquarium filters were invented in 1949, the best way to ensure that broodstock (mature fish used for breeding) had clean, fresh water was to change it frequently or otherwise ensure that there was a steady supply in and out. In the case of fish farming in the modern era, this is achieved by the use of floating pens where fish can swim freely while remaining protected – though broodstock are mainly kept onshore in tanks, which creates a need for a more modern solution such as an industrial water filter system.
How Modern Fish Farming Works Now
Female halibut broodstock typically produce around 100,000 tiny eggs per kilogram of body weight which, once fertilized, are maintained in tanks that are both filtered and temperature controlled. Eventually, they’ll be moved to floating pens where they can get lots of exercise to keep them strong and lean, but this initial growing period is crucial to their health, happiness, and ultimately, their tastiness. By filtering the water and removing bacteria, the survival rate of halibut raised in these hatcheries is much higher, and they can be raised without many of the chemicals and antibiotics that were often required in the past. This is all thanks to modern solutions such as the industrial water filter system offered by Aqua Ultraviolet.
What Does an Industrial Water Filter System Do?
Our industrial water filter system uses ultraviolet (UV) light to destroy bacteria, viruses, microorganisms, and other contaminants and keep the water in onshore tanks fresh and clean while still providing halibut with optimal growing conditions. Halibut are most vulnerable when exposed to foreign harmful bacteria, but the UV light in products such as our Viper SL Professional Series UV Sterilizer alters the DNA of single-celled organisms rendering them harmless and effectively destroys their ability to interfere with the healthy growth of the fish.
Benefits of Using an Industrial Water Filter System
Compared to other methods used throughout the course of history in fish farming, the use of an industrial water filter system has a long list of benefits, including:
- Decreased need for chemicals
- More natural and ethical growing conditions
- Fish can grow organically without the use of antibiotics
- Destroys bacteria, algae, and protozoa
- Environmentally sustainable
