Fish breeding includes commercially cultivating fish in ponds. In recent years, farmed fish for subsistence food has become common as more individuals strive to provide their families with safe supplies of farmed fish. In rivers, pools, or tanks, fish farming may be achieved on a small scale.
Tanks allow the fish farmers to handle stocks efficiently and exercise a high degree of environmental control over parameters such as water temperature, dissolved oxygen (DO), pH, and waste that can be adjusted for optimum output of fish. In contrast to ponds, when raising fish in pools, feeding and processing operations require less time and labor. Tiny quantities of tanks make the treatment of certain diseases with medicinal chemicals dissolved in culture water feasible and economical. On small parcels of land, intense tank culture can achieve high yields.
A Guide to Fish Farming in Tanks
Rearing tank means a tank where the breed (to achieve a size of 10-15 cm) is reared into fingerlings and the period of culture is 2-3 months. With a water depth of around 1.5 to 2.0 m, the area of the tank ranges from 0.05 to 0.1 hectare.
In order to balance the benefits of circular tanks and rectangular tanks, oval tanks are an initiative. It has the circular tank's effective water usage and self-cleaning action and the space efficiency of rectangular tanks. It is used in indoor and outdoor intensive structures, where aeration technology is applied.
Since they appear to be self-cleaning, circular tanks are common. Rectangular tanks can be built very quickly, but also have poor flow characteristics. Incoming water may flow to the drain directly, short-circuiting the tank, while other parts of the tank become stagnant, causing waste to collect and reducing the amount of oxygen. For these purposes, circular tanks have ideal conditions for raising tilapia fish than rectangular tanks. While tanks can be as big as 100 feet in diameter for circular culture, typical sizes vary from 12 to 30 feet in diameter and 4 to 5 feet in depth. The dimensions and height of rectangular tanks are largely variable, but raceways have unique dimensions that require proper operations.
The suggested features for fish harvesting in tanks are as follows:
1. To avoid abrasion, the interior surface in tanks should be clean.
2. It should be nontoxic to the surfaces.
3. The tanks must be durable and compact, long-lasting, easy to clean and easy to sterilize.
4. It must be affordable and non-corrosive.
Tanks come in a different range of sizes, but circular and rectangular are the most common types. Circular tanks are widely used for nursery purposes and are often used for growth. Square and rectangular tanks allow use of space effectively and save on building expenses.
The pH level of the tank should vary depending on fish species selection. Different species of fish like different water conditions. To discover what condition the water is in, we will have to complete regular pH level testing.
Best Fish Breeds in Tanks
Blue Tilapia- Blue Tilapia, since they are the cold resistant, they are perfect for raising fish in tanks. One can start a breeding colony in a smaller tank, or even in big tanks, if they don't want to buy fresh stock for each rising outrun. In order to prevent a great deal of water quality and feed control, stocking densities must be modest. Assuming a target weight of around 2-2.5 lbs/fish, per 5 to 10 gallons of tank length, people can keep the density down to one fish.
Blue Nile Tilapia- It is one of the most common varieties for small-scale aquaculture systems, is also known as Rocky Mountain White tilapia. They are fast-growing, disease-resistant, and very pretty, tolerant of bad water conditions. There would be an ideal water temperature of 23 to 29 ° C.
Salmon-Salmon have similar requirements to trout, but are more vulnerable to low quality of water. An extra difficulty is that they are raised from eggs, which to pull off takes a little more scientific experience. 7 to 12 ° C, is the ideal water temperature range.
Trout-Trout grows slowly, but to learn how to raise them efficiently, the excellent flavour can be worth the time commitment required. The ideal temperature of the water would be 10 to 15°C.
Catfish- Not only is catfish raising fast in tanks, it is also perfect for you who do not have a big enough land to grow large-scale catfish farming. Fish respond to a wide variety of environments in the sea. There would be an ideal water temperature of 23 to 29 ° C.
Perch- There is a range of perches suitable for small-scale tanks, but the most common species is yellow perch, a native of the Great Lakes. These fish species produce better, though still not as quickly as tilapia, than most other perches.
