The suitable for growing prawns in a moderate ability of salt water (18-30%). This kind of water flow and spreads are suitable for growing of prawns. That spreads are joined to the sea of estuaries, salt water pan, spreads of mangrove forest brackish water, matted water, field of brackish water in Kerala and then too in West Bengal (Bheries). The total spreads situation of brackish water in Indian sub continent is 2.6 million hectares. In this the importance of areas are in Kerala districts are Ernakulam, Alleppey, Trichur the sea shore of Pokkali fields (4500 hectares) and in West Bengal mangrove forest (5200 hectares). In South India the total spreads of prawns growth parts will be more than 80,000 hectares.
This spreads can be used for prawn growth?
If it is possible we can achieve it likewise, we can’t think over it. ”this can be suitable for prawns growth” to say that spreads can be taken to one note only. By practical we have to visit and inspect each part, if the spreads will be seen more and if the size is suitable we can easily grown up the prawns in the suitable place. Though planned, we must know the defect of each part and remove it in a science method and then proceed to the growth of prawns or particularly, instead of growing prawns in all places we must see the suitable place for the growing of prawns and we must do some changes and proceed over the method in an easy manner. This kind of approachable method will be possible. We don’t have any compulsion that growth of prawns should be done only in brackish water and we grown up the prawns in brackish water is about 35-40ppt and we have to pay some attention towards this method.
In West India they changing the untidy region into regulate, equate, cutting down the trees and roots and making ridges to growing the prawns. Rather they are using spreads it’s seems to be like a pond. Like this kind of using ponds can be called as Redaimed ponds. This ponds production ability will be from 3000 to 4000 hectares in one year.
In Southern India of Kerala, the joins of Vembanadu there are plenty of seashore mangrove fields, In North east monsoon season the saltiness ability will stand 6-8ppt and they tilth the paddy in a type Pokkali. During not in the time of rainy season these fields the presence of salt water domination will be seen more. At that time we must patronize the ridge and the juveniles that enter with water into the fields should be condensed. In this method they patronize the ridge they doesn’t much care about that, These kinds of fields will be called as seasonal ponds. Their salt ability will be from 300 to 1200kgs.
Like this, In Tamil Nadu the parts like Tuticorin, Vedharanyam and Marakaanam during rainy season the rain water aggression is strong in saltpan. If it is rainy water it could stand in the place of salt land, rain water junction is saltwater, so the rain water becomes saltiness. This water ability is corresponding to salt water. If the water stands for 3 months we can grown the prawn at least once, we can grown up the prawns in Kerala with the salt water field. Likewise, we have the chance of growing up in Tamil Nadu. This is how much reliable will be depend on the down rain and their ability. Anyway we have to pay attention to make ridge and rather the condensed rain water. The stock of salt pan prawns (P.Manodon) should be seen in Kaakinada, Kaniyakumari and Manakudi and we should think about the consequence.
In some places the joins of sea shore part we must know the quality and ability of land. Dig the pond, irrigating the salt water, now and then we have to exit out the water and irrigate the new water and we have to maintain that the ability of salt should not be increased more like this kind grown places said as excavated ponds. The expense will be more to excavated like this kinds of ponds we must choose the spreads that seems like pond we have to pit and change it into a pond and it should be comfortable like this kind of approachable method is good and the investment expense will be less too like this kinds of ponds we can grown up our prawns with full of condition and from this we hope that the production will be more.
In ponds the stands water depends on the saltwater ability. It’s get apart and work. In this method the saltwater ponds can be say that seawater ponds and brackish water ponds. In sea we can distinguish as 6 parts, in sea shore the intertidal zone and littoral zone parts we can grown up the prawns.
In seashore we have to make the salt water ponds should mix with clean water during rainy season of not getting the chance. In the ponds the water should come and go due to sea dense level. Naturally in sea water salt ability should be more if it increases again the prawns does not grow into the place. If the saltiness does not increase we have to concentrate in management. If we make prawns farm in this places there is only one danger that is the increasing ability of saltwater. If we exit out the water in particular time we can know about the quality of water.
These types of ponds or prawns farm have the chance that should be gathered with the production of saltwater. We can take the water from sea for the production of salt should be reservoir, in this we can grow the prawns. In this spreads we take out the water and irrigate, for once in a seasonal after this consecutively in reservoir with the help of evaporation, in water saltiness will be more in last reservoir the water should irrigate to the salt bed if we did like that in less season we can get the more salt production.
Like this kind of salt production method in some parts of Tamil Nadu. But in first attempt with big spreads if we irrigate the sea water, it is useless depends on the growth of prawns. If we grow up the prawns in this kind of places we can get the more production. We can get the way for gathering salt production and the growth of prawns.
