To begin the farming of fish in tanks it is necessary to have specific knowledge of fish, on playback-induced, asexual, forms of power and conservation after the abatement, and the many details involved in this theme. In addition to master everything about the creation and reproduction of fish, the entrepreneur needs to know about business management. Be creative and receptive to innovations.
It is worth to create fish
The demand for fish growing so fast, and the fish comes to meet this need. Even, in an attempt to reverse the reality: extinction of some species. So much for fish that will follow for the aquarium, or to the dish of the population.
The recommendation of the World Health Organization is consumption of 12 kilograms per inhabitant per year. And the potential of brazilian production is great.
The climatic conditions in the country allow for the development of the activity for the various species. But before choosing the species, the ideal is to consider the available budget.
How to evaluate the details of the facilities
The topography of the site chosen, the quantity and quality of water must be considered. The conduit can be open or closed.
The tank can be built being directly dug in the earth, or can be built in masonry and waterproof.
It is recommended that the nurseries are not large, a good measure is 40 by 50 meters, with 1.60 metres of depth.
The rectangular shape facilitates the renewal of the water.
The circular form is often used in the creation of trout, although it also serves for the cultivation of tetra, tilapia, and arapaima, among others.
Should also be observed in local suppliers of inputs, and the ease of flow of production.
The cost of cultivation in tanks is less than the cultivation in cages, for example. And as the fish remain confined to the rations provided are nutritionally complete.
How the carp behave in captivity
The common species is cultivated around the world, is resistant to diseases, easy playback and management.
The colorful variety is very suitable for decorative purposes. The scales and the mirror are also widely cultivated.
This species adapts easily to different types of food, and has fast growth reaching a pound and a half in a year.
Carp grass has big head and silver. Their feces are plentiful and fertilize the water. In captivity, only if you play in an artificial way. Reaches a kilo and a half in a year.
The carp of big head does not accept the feed. But can reach two pounds in a year.
What the fish need
In addition to water, the food offered to the fish can be natural, such as organic material in decomposition. And the supplementary such as rice bran, husks of vegetables, termite, and others.
It’s good to know that the oxygen in the water decreases during the night. And the safety of the fish in relation to predators must also be observed.
The amount of fish that can share the nursery depends on the size of the nursery, the type of fish, size of fish, the depth of the water.
The production consists in the installation of the cultivation, the settlement and fattening, in the despesca and slaughter. The processing consists of cleaning, weighing, packaging and storage. This is all done before you move on to the marketing.
The cultivation of fishes in tanks is something attractive.
Requires quite a lot of commitment for the deployment of this type of project, especially in regards to the rules and legal requirements.
