Facts and Tips on Fish Farming
Fish farming is not only giving a considerable rise in the employment sector but aquaculture altogether is expected to be doubled by the year 2030. (United Nations)
According to a survey, each American eats around 17 pounds of fish on an average closely followed by the Chinese and Japanese.
Increasing worldwide population and food requirements is the reason behind this surge and expected growth and gives us an assurance enough for starting this occupation and make money out of it.
It is the highest sector in the graph of food production followed by normal fishing, i.e. catching. It was whopping 47% in the year 2006.
It has been observed that where fish farming is done on a considerably big scale, they tend to over populate and over breed them in a very congested and small place as compared to the number of fish.
This over-crowdedness results in pollution as meticulous cleaning cannot possibly happen and since fish consume their food in the same polluted water of the tanks. Hence, chances of falling ill is high which in turn is bad for us humans who consume them.
The vicious circle does not stop here. For treating the pollution and the sick fish, the water is further pumped in with purifying chemicals, antibiotics and vaccines for which government-banned chemicals are used. In spite of being banned, and the lack of security and quality checks, these fish travel all the way happily to our stomach.
If the fish from the fisheries escape, obviously the result is not just the loss incurred by the aquaculture farmers but it contributes negatively to the ecosystem as well.
For beginners, Tilapia farming is the best option as these fish are the most environment friendly. Apart from that, Tilapia being a vegetarian fish (herbivore) it is likely to incur very less expenditure on their food expenses.
Another reason for people choosing the tilapia is that it can be farmed in tanks, rather than pools. Catfish, Carp, Cod and Salmon are some of the other common fish that are farmed.
Oysters and Mussels are also easy to farm because of two main things. Firstly, they are not very mobile which makes them very easy to handle and maintain. Secondly, they filter the tank water which makes them environment friendly too.
If you are choosing Salmon, then you should know that they are very high maintenance, as they require almost twice to five times as much food in proportion to their own weight.
Amongst the most destructive type is of Shrimp. One of the reasons is that the salinity of the soil increases. The trend of farmers of changing the areas of farming frequently leaves the area unused and unfit for agricultural purposes thereafter.
An important tip for backyard fish farming is that before you start with acquiring the fish and tanks, etc. you should take care of the water purification and sewage management process. Do a little research on the different ways and techniques, for example, cages, recirculating, raceways, etc., that suits your budget as well as convenience.
Also think beforehand about the small fry... What to do with it? Where to keep them? Their food, maintenance, the temperature control, the equipment and machines required for the same, etc. Consider the purification materials too that would be required for the same purpose. Follow the rules and regulations of your area, state, whichever is applicable depending upon the size of your home fish farming.
