Fish farms or fish farming is really a type of aquaculture. The act of fish farming is approximately raising fish commercially in tanks or enclosures for human consumption. There are different kinds of fish farms that utilize various aquiculture methods.
The very first technique is the cage system which use cages which are placed in lakes, ponds and oceans that contain the fish. This technique can also be extensively known as off-shore cultivation. Fish are kept in the cage like structures and therefore are “artificially fed” and harvested. The fish farming cage technique has made numerous technological advances over the years, particularly with reducing illnesses and environmental issues. However, the quantity one concern from the cage method is fish escaping and becoming loose among the wild fish population.
Your second technique is irrigation ditch or pond systems for raising fish. This basic requirement due to this technique is to possess a ditch or perhaps a pond that holds water. This is a unique system because in a little level, fish are artificially fed and also the waste produced from the fish is then utilized to fertilize farmers’ fields. Over a bigger scale, mostly in ponds, the pond is self-sustaining as it grows plants and algae for fish food.
The next method of fish farming is called composite fish culture that is a type of fish farming that enables each nearby fish species and imported fish species to coexist within the same pond. The amount of species depends, but it is occasionally upwards of six fish species in a single pond. The fish species are usually carefully selected to make sure that species can coexist and reduce competitors for food.
The fourth method of fish farming is called integrated recycling systems that is considered the largest scale technique of “pure” Fish Farming in Nigeria. This method uses big plastic tanks that are placed inside a greenhouse. You will find hydroponic beds that 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 provide nutrients to the plant crops which are grown within the hydroponic beds. Virtually all kinds of plants which are grown in the hydroponic beds are herbs such as parsley and basil.
The last kind of fish farming method is known as classic fry farming this method is also referred to as “flow through system”. This is when sport fish species are raised from eggs and therefore are place in streams and released.
There are a number of different fish species which are raised on fish farms, the most common fish spices raised are salmon, carp, tilapia, catfish and cod.
Catfish are simple to farm in warmer climates. Catfish are predominantly farmed in fresh water ponds and fed mostly soybeans, corn and rice. Catfish are often considered among the more sustainable fish specifies for fish farming purposes. Cultivating catfish first started in the 1900s and became commercialized in the 1950s. Catfish is populous because of its health benefits and marketplace demand. Farm-raised catfish are usually harvested at 1.5 years of age where as wild catfish generally get a lot bigger. There are a number of catfish species, but the three most prominent ones are blue catfish, channel catfish, and flathead catfish.
