Farming Taking Advantage of Fast Mud Crab
Growth Rate
The mud crab
growth rate inside the farm can reach half of what they usually need
when growing naturally. That is why; the labor and production cost that the
farmer has to spend can be suppressed as low as possible. Furthermore, as the crab
grows very fast, then the farmer will be able to get back their investment
after a while. Thus many people that living around the coastal area chooses to
do the mud crab farming for their business. Furthermore with the right
management done on the farming business, their profit might even be larger than
doing shrimp farming business. This makes people love to do this kind of
farming, so you might be interested to do one by yourself.
If you want to know, there are actually
several types of mud crab that is used on the farming business. Those types of
mud crab are still within the Scylla genus but they come from different
species. The first one comes from the green crab species while the second one
comes from the red claw species. Both of the species actually have high mud crab growth rate which make them suitable
to be used on the commercial farming business. In fact the green crab species
can get into maximum carapace width of 22 cm with maximum weight of 2 kg. Then the
red claw species can get into maximum carapace width of 12.7 cm with maximum
weight of 1.2 kg.
The demand for both mud crab species are
also very high in the market. With their high growth rate, then the farmer is
still able to fulfill the demand even though the demand is actually very high. To
fulfill those high demands, the farmer will actually use two production methods
which both use the high mud crab growth rate count
to their advantage. Those production methods are the growing method as well as
the fattening method. Now let us see how this production method takes advantage
of that growth rate.
On the growing production method, it will
take advantage of that growth rate that the young crab has. In the production,
the young crab that has high grow rate will be growing inside the production so
it will become bigger and reach the suitable sizing to be sold for commercial
usage. Because of the high growth rate, then the production will only take
around five until six month time so the crab will reach the suitable sizing to
be sold for commercial usage. As you can see, the high growth rate will really
help the production so it can be done fast.
The production method that using growing mud crab growth rate is done inside pond
with varied sizing which will depends on the scale of the method used. But
usually the farmer will be using pond that has size to be at 0.5 ha until the
size 2 ha. Then the pond should also hold strong bund and the water exchange
should also be great. If you have just start the business and only want to pay
attention to the growth rate first, then you can actually use smaller size pond
since you will be easier to maintain it. Then you can use fence for the bund so
it will become stronger. But if you are ready to do the large scale production,
then you can always do the production in larger scale. For this one, then you
can use natural material bund which will be easier to build, but do not forget
that you also need to strengthen the bund with fence in the future.
On the fattening production method, it will
take advantage of that growth rate that the soft shell crab has. In the
production, the soft shell crab that has high grow rate will be growing inside
the production so it will become hard shell when it reach the suitable sizing
to be sold for commercial usage. You need to know that the hard shell crab will
valued higher than the soft shell counterpart. Their value will even reach
around four until five times higher than the soft shell counterpart. Because of
the high mud crab growth rate, then for one
year you can even do eight until around twelve production cycles. As you can
see, the high growth rate will really help the production so it can be done
fast thus you will be able to earn huge profit when doing this production
method.
The production method that using fattening mud crab growth rate is done inside pond
with 0.25 hectare until 0.2 hectare sizing and the depth would be in 1 meter to
1.5 meter. Remember to prep the pond first before usage by draining it to
gather the lime as the foundation for the floor mat that you put which made
using bamboo material. Then on the bund, you will be able to add some fence so
it will be stronger.
As you can see, both of those production
methods are actually done by taking advantage of the growth rate that the mud
crab has. Because the mud crab is growing inside controlled environment with
good feeding system, then they are able to have fast
mud crab growth rate which even faster than when they are living in
their natural habitat. Because of this the farmer is able to gain huge profit.
