Fish farms or fish farming is a form of aquaculture. The act of fish farming will be close to raising fish commercially in tanks or enclosures for human consumption. There are various types of fish farms that utilize different aquiculture methods.
The first method is the cage system which use cages which are placed in lakes, ponds and oceans that include the fish. This technique is also widely referred to as off-shore cultivation. Fish are kept within the cage like structures and are “artificially fed” and harvested. The fish farming cage technique has produced many technological advances more than the years, especially with decreasing diseases and environmental issues. Nevertheless, the quantity 1 concern of the cage method is fish escaping and becoming loose among the wild fish population.
The other technique is irrigation ditch or pond systems for raising fish. This basic requirement for this technique would be to have a ditch or a pond that holds water. This is a distinctive method simply because at a small level, fish are artificially fed and also the waste produced in the fish is then utilized to fertilize farmers’ fields. On a bigger scale, mostly in ponds, the pond is self-sustaining because it grows plants and algae for fish food.
The third method of fish farming is called composite fish culture which is a type of fish farming that allows both local fish species and imported fish species to coexist within the same pond. The number of species depends, however it is occasionally upwards of six fish species in a single pond. The fish species are usually cautiously selected to make sure that species can coexist and decrease competitors for food.
The fourth technique of fish farming is known as integrated recycling systems which is considered the largest scale technique of “pure” Fish Farming in Nigeria. This approach uses big plastic tanks which are placed inside a greenhouse. There are hydroponic beds which are placed close to the plastic tanks. The water within the plastic tanks is circulated towards the hydroponic beds, where the fish feed waste goes to supply nutrients to the plant crops which are grown within the hydroponic beds. A large number of types of plants which are grown within the hydroponic beds are herbs like parsley and basil.
The last kind of fish farming technique is known as classic fry farming this technique can also be known as “flow through system”. This is when sport fish species are raised from eggs and therefore are put in streams and released.
You will find a number of various fish species which are raised on fish farms, the most common fish spices raised are salmon, carp, tilapia, catfish and cod.
Catfish farming
Catfish are easy to farm in warmer climates. Catfish are predominantly farmed in fresh water ponds and fed mostly soybeans, corn and rice. Catfish are often regarded as one of the much more sustainable fish specifies for fish farming purposes. Cultivating catfish initial started in the 1900s and became commercialized within the 1950s. Catfish is populous simply because of its health advantages and marketplace demand. Farm-raised catfish are often harvested at 18 months of age exactly where as wild catfish usually get much bigger. You will find numerous catfish species, however the three most prominent ones are blue catfish, channel catfish, and flathead catfish.
