shrimp farming (partial part 2)
Regards steemit, tonight I returned with shrimp farming stage 2, yesterday I have explained phase 1, and today I will try to write a little about the cultivation of shrimp stage 2,
Market demand for fish, especially shrimp both domestic and export is still quite high. This is due to the lack of shrimp farmers. This opportunity is a hatus taken for entrepreneurs, especially in the field of agribusiness.
Freshwater in the concept of shrimp vannamei cultivation here is not fresh water as in the interior or fresh water is pure, but fresh water contains very little salt in accordance with the requirements of live shrimp vannamei. Because the salt content is very minimal so it feels close to fresh water.
Shrimp is an animal euryhaline, which is able to adapt to the salinity range / salinity is large, ranging from 0.5 to 50 promil promil. Therefore vannameibisa shrimp is cultivated at very low salinity, even close to bargaining. But that does not mean that vannamei shrimp can be kept in the countryside. During this time the shrimp are maintained in coastal ponds with fresh water or low salinity.
In addition, the shrimp density and the size of shrimp harvest that can be achieved is also limited. Usually the freshwater cultivators can only maintain about 6.6 12.5 grams only, or about size 150 80 tail / kg.
The stage of nursery is the decisive stage of the continuation of the cultivation effort because this step is the process of adaptation of fries from a high salinity environment to an environment that will eventually close to zero
The eggs purchased from the hatchery usually have around 30 promises. The eggs are then stocked in a plot that is almost the same salinity as the hatchery, which is about 30 permils. Furthermore, fresh water is added slowly for 10 to 14 days, so the salinity is close to 0.5 ppt.
Water used for running better if the plot with the water of bargain will be used to raise the shrimp later. The expectation of adaptation can be more perfect. If the pond has only fresh water, it should bring sea water. Do not add salt to make artificial sea water. Can also use salted water from salt ponds, then water is diluted.
