The growth and development of the Animal Husbandry Crab business From category Business, Crab Below : Product Details : Crab businessCrab fishery is one of the commodities brought to its attention, because besides the price is quite expensive in the local market, also provided opportunities for the export market. In the domestic market was still limited crab supermarkets in big cities.
Products currently still relies on crab catches the angler, then accommodated by the merchants and so on by the traders are marketed to supermarkets or to consumers directly.
But there are obstacles encountered by traders that the crab is no requirement that must be met in order for crabs sold in the market with high prices. Requirements for good behavior crabs are:
1. The mature crab eggs (These criteria are crabs that have a high enough price).
2. Crab fat (this criterion is lower price compared with a mature egg).
In line with the above, it is necessary so that the crab would be held businesses have marketed the criteria desired by consumers.
One of the most appropriate business today is the cultivation of crab fattening. The period needed for cultivation is quite 1-3 weeks to be harvested with selective manner.
CULTURE METHOD
Crab fishing methods there are several ways such as:
* With a stretch of pond system (Figure 1), the size of 5000 m2. At 5 ekor/m3 spreading, but to find the seeds of which amount to thousands at once is not possible. Stocking of seedlings generally be gradual and selective way memanennyapun too.
* With bamboo karamba system (Figure 2). Length 2.5 m, width 2 m and height 1.75 m. Stocking density 25-30 ekor/m3. Cage was installed in the river channel that is not too heavy, for example in the estuary. Fitting done so fourth part is not submerged in water.
CULTIVATION TECHNIQUES
1. Site Selection
As with other aquaculture operations, in this crab farming also requires that the location requirements must be met. This is so that dreams can achieve success. Terms of crab fishing locations include:
* The river is not heavy
* Many of the mangrove trees on fire or fire-
* The depth of not more than 75 cm
* Sources of water available throughout the year
* Concentration of salt between 15-30 ‰
* The temperature varies between 24 - 32oC
* PH between 7.0 to 8.5
* Water is not polluted by toxic waste
2. How to Get Seeds
The success of an aquaculture farming techniques which are supported in addition to reliability, availability of seeds is also very crucial. For crab fattening, farming is no way to get seeds are: The fishermen sell to traders, by traders who then selected in accordance with a preset sizes, in order to measure the consumption of fish farmers sold directly to farmers. Usually the size of crab seeds varied between 100-200 grams.
3. Feeding
Crab including animals Carnivora (meat eaters). Feed ingredients for the crab is easily available. Crab feed in the form of trash fish, snails, wideng. The food is done 2-3 times a day, ie morning, afternoon and evening. The feeding dose of between 5-15% of the estimated weight of crab are kept.
4. Harvesting
Crab fattening maintenance period is relatively short or also depends on the initial stocking of seedlings. For 100 grams of seed size in the maintenance period 1.5 - 2 moon to reach consumption size (3-4 fish / kg). However, if the beginning, had the weight of more than 200 grams, then the maintenance period could be shorter. Farmers harvest the crabs is done selectively by way of fishing and separating between the fat and cooked crab eggs. Crabs are cooked eggs have a higher price than others. Then crab legs tied with raffia rope or rubber and then inserted into the basket.
5. Marketing
Marketing crab consumption there are no problems, even the unmet demand for production of crabs until today still rely on the catch. Marketing crabs can be done in the market, supermarket, middlemen (depot) or businessman restaurants
provides sea food.
