You might be curious about the mud crab adaptations as this creature itself is very unique in nature thus there are still not many people who knows about them. Especially for their adaptations since they live in estuaries area where there is brackish water as their habitat. Sometimes, you will even need hard time to find this shellfish as you need to dig around the mud to find one. As the mud crab it is very delicious food fish, and then this shellfish is often farmed to ensure stabile supply for consumption. Because this creature can adapt very well with the condition inside the farm, thus they are able to grow very fast.

What is Mud Crab Adaptations to Survive?

There are various mud crab adaptations that are done by this creature in order for them to survive in their natural habitat. The first thing is their behavioral adaptations where they will hide themselves inside the mud by digging the mud using their claws. They will create some type of hole where they can hide their whole body inside the mud. The mud which is very dark and muddy will give them a lot of protection that they need from their predators. Furthermore their color also works as camouflage so they can easily hide inside the mud without being easily detected by their natural predators. That is the reason why; sometimes, it is quite hard for you to find the mud crab even when you already go to the mangrove region where they usually live.

Another behavioral mud crab adaptations that they do is to look their food even in intertidal zone where they can find their food there during the time of high tide. However, this is only temporarily as they will go back into the sub tidal zone during the time of low tide to the place where they actually living. Of course, there are various mud crab species available thus the place where they prefer to live is also different from one another. As they can adapt very well with the change in the water and its condition, then they can survive in most condition available. This is why a lot of people are interested in doing the mud crab farming to make use their behavioral adaptation for their advantage. Sometimes, this shellfish is also growing inside aquarium at home since this creature is also quite entertaining for some people.

When it comes to physical mud crab adaptations, the first thing that you notice is their skeleton. This creature is actually different from other creature where their skeleton lies inside their body. However, for the mud crab, their skeleton actually put outside their body as their shell which will then be called as carapaces. Even though this skeleton is an exoskeleton, however it is actually very similar to our own skeleton which is rigid in structure. Their shell is also very hard thus it can protect the mud crab especially for their internal organ which lies inside the shell. That way, then can protect themselves better from their natural predator by having that very hard shell as their armor.

Next physical adaptation that you will notice is on their claws. As you know the crab actually owned eight legs naturally. And two of those legs are adapted so it will become the claws which have bigger and stronger shape compared to their other legs. Furthermore, these claws are actually very important mud crab adaptations since they have various usages for the crab themselves. First is of course to feed themselves where they will use their claw to grab their prey and catching it. Next is to defend themselves from predators so they can fight their predator using the bigger and stronger claws that they have. And sometimes, there are a few species of crab which also uses their claw during the mating process. However the usage is actually different for each species. For example, sometimes the claw will be displayed so they can attract the female during the mating process. And the claw can also be used to fight other male crab so they can win the female attention which will then mate with them.

The mud crab is actually very unique type of crab which is very different from their fully marine crab which will spend most of the live time inside water. Since the crab is naturally a marine creature, then they will actually using gill to breath. However, this would be a problem for the mud crab which sometimes goes out on the surface of the land without any water. That is why; some species have unique mud crab adaptations which can help them cope with this problem. For example, there are some crabs that have a special designed plate which can be closed tightly so they can keep some of the water inside the body. They will then use that water which stored inside their body so they can breathe through it. But some species prefers to just go into puddles of water to breathe and some prefers to store the water inside their blood or bladder.

Other unique adaptation that the mud crab do is on their senses which actually be done using the antennae as well as antennules which comes in sets. The antennae will be used by the crab so they will be able to feel the environment that surrounds them. Then the antennules as some chemoreception which will then be used by the crab so they are able to taste and shell their surrounding environment. They actually are also able to see using their eyes which is put on the point of the eyestalks. They have eyestalks so they can see better to all sides of their body which is usable for them especially when they are trying to find prey for their food.

By doing all of those essential mud crab adaptations, then the mud crab can survive well in their environment. They will be able to find their prey well and protecting themselves from any danger including the predators which they can fight.

You might be considering to do mud crab farming in freshwater but is that even possible as the mud crab is actually living in brackish water. Actually the mud crab can live in mangrove habitat where there are both freshwater and also salt water which will be combined into brackish water. Thus actually they do not really live in the freshwater area. And even if they do, then they will only able to survive for very little time inside the freshwater environment. This makes it impossible to farm the mud crab using freshwater. Thus the only thing that you can use to farm the mud crab is the brackish water.

The Truth about Mud Crab Farming In Freshwater

Then if the mud crab farming in freshwater is impossible what you can do to farm this shellfish? Actually the mud crab is very sensitive with the salinity level of the environment that they living it. Thus the only thing that you can do is to farm it using brackish water as the environment. In fact a lot of people already farm the mud crab especially those who are living in the coastal area where there are natural brackish water area. They will make use of that area to create ponds to farm the mud crabs.

The best thing about this farming is that you do not need to have huge budget to start the farm. In fact this farm can be done with small scale thus everyone can start to make one if they want. Furthermore the labor cost is actually pretty low which make it ideal for those who only want to start their first business. But even with that low cost and budget, that does not mean that their income will also be low. On the contrarily, farming the mud crab is able to give them huge income as the price of this shellfish itself is very high. Thus you would most like gain a lot of profit as long as you do not do mud crab farming in freshwater.

Usually there are two kinds of mud crab that is being farm by people for commercial usage. Those two mud crabs are actually still under the same Scylla genus and they are the green crab as well as the red claw. There are several differences that both of those mud crabs have, which you need to learn if you want to decide which one to use inside your farm. For the green crab it will have larger size, their carapace can grow until 22 cm width and their weight can reach until 2 kilos. Meanwhile for the red crab it will have smaller size, their carapace can grow until 12.7 cm width and their weight can reach until 1.2 kilos.

Now, once you have decide which one to use in your farm and make sure you do not do the mud crab farming in freshwater, then you can start to do the farming process. To start the farming process, first you need to choose which process that you want to use. As there are two kinds of process that you can actually use which is the growing out process and the fattening process. Both are actually used by various farmers since there are some differences that the processes have. Now let us learn more about the differences here.

On the growing process, the one that is being raised inside the farm is the young crab. Through this process the crab will be grow so it will then be bigger after some times. It usually takes around five until six months time until the crab is big enough as it already each the commercial size and weight that the market want. The growing process itself will be done inside a pond which the size is varied according to the farmer budget. The usual size is around half hectare until two hectare. As this process is not mud crab farming in freshwater, then it is good to do the farming inside small size pond so the maintenance can be done easier. Furthermore you can use fence as boundaries for the smaller pond. But if you use natural boundaries, then you might need to strengthen them after some times when it begins to deteriorate.

Meanwhile for the fattening process, the one that is being raised inside the farm is the crab with soft shell. Through this process the crab will be raised so the shell will then be harder after some times. Mud crab which has hard shell will have higher value compared to those with soft shell which may even reach around four until five times higher. Furthermore the farming process on this is actually faster thus you will surely gain a lot of profit as long as you do not do mud crab farming in freshwater.

The growing process itself will be done inside a pond and the usual size is around 0.25 hectare to 0.2 hectare. Before using the pond, the tidal pond need to be drained so there will be more lime in higher quality as the foundation of the pond. Next use bamboo mat for the flooring as well as fence to strengthen the boundaries. This will then prevent the mud crab from escaping the pond area. Usually in one year you will be able to do around eight until twelve cycle of farming as long as it is not mud crab farming in freshwater.

Once you have learn those farming processes that you can use to farm the mud crab, then you can decide which one that you want to use. There are a lot of people that trying to do this business since the farming process can be done in very short period with low budget. They would also able to earn huge profit from the harvest since the mud crab itself holds high economical value. Just make sure that you do not do mud crab farming in freshwater since the mud crab cannot survive in freshwater environment for a long time and will most likely die if you insist.

Mud crab scientific name is Scylla serrata which known as one of the most popular crab to be consumed due to the incredible big size and nice taste. It is an important species for fish industry because it sold in high price. The crab can be found mostly in the estuaries as well as areas like mangroves of Africa, Asia, and Australia.

Aquaculture and consumption of mud crab is high in market demand due to the high price, impressive size, and rapid growth rates in term of captivity.

Furthermore the market for mud crab is actually quite large as there are various countries that actually importing this shellfish every year. And through the mud crab farming, the farmer is able to get foreign currency which means their profit will also be huge because of the currency exchange value.

Farming Technique on Mud Crab Aquaculture

There are various reasons why the mud crab aquaculture is actually very popular. First might be because the labor cost that is needed to do the aquaculture for this shellfish itself is very small compared to the other type of food fish aquaculture. Next is the growth rate of the mud crab which actually also very fast thus the farmer will be able to gain back their money faster compared to other type of aquaculture. And if the aquaculture is done in great management, then the profit that the farmer can get might even be higher than those provided from shrimp aquaculture. The best thing is that the aquaculture for mud crab can also be done in smaller scale, which means more opportunity for small farmer to gain profit. This might be the reason why there are a lot of people that want to do this aquaculture as their business.

If you want to do the mud crab aquaculture, then you need to be able to identify the mud crab that you will farm. The mud crab actually comes from Scylla genus, and usually there are 2 species that you can use for the aquaculture which are the green crab as well as the red claw. To identify those mud crabs are actually very easy since both of them are different. The green crab has bigger sizing which can reach around 22 centimeters for the width and around 2 kilograms for the weight. Then for the red claw, it has smaller sizing which can reach around 12.7 centimeters for the width and around 1.2 kilograms for the weight.

Both of those mud crabs are very suitable to be used on aquaculture since the demand for both mud crabs are also very high and their value is also as high. If you want to try doing the aquaculture by yourself then you need to know several mud crab aquaculture technique that you can use for the aquaculture. As there are two types of techniques that the farmer can use for the aquaculture which are the growing technique and the fattening technique. Now let us learn more about those techniques in more detailed explanation below as both of those techniques are actually a little bit different

On the growing mud crab aquaculture technique, the aquaculture will be using young mud crab. Then the mud crab will be nurture until it become bigger for some duration of time until they are suitable to be sold commercially. Usually the duration of time is around five months up to six months duration according to the facility and the condition of the pond. The mud crab will be nurtured inside pond which have various sizing from half hectare to two hectare in size. The pond should have great water exchange which usually takes advantage of the tidal wave. It should also have good boundaries which can be made using natural material or fence.

Actually this type of aquaculture technique is very suitable to be done using small size pond. That way, you can easily maintain the pond without having to do a lot of things which may take more labor hour. Furthermore, on the small pond, the boundaries can easily be made using fence which will be stronger. However, if your pond has larger size, then it is possible to use natural material for the boundaries. But remember to reinforce the boundaries with fence in the future since it will be deteriorate overtime.

On the fattening mud crab aquaculture technique, the aquaculture will be using mud crab that has soft shell. Then the mud crab will be nurture until the soft shell become hard for some duration of time until they are suitable to be sold commercially. You should know that the mud crab that has hard shell will also has higher price which may even reach four until five times higher price compared to the mud crab with soft shell. Furthermore this aquaculture technique will take shorter duration. Thus you will gain a lot of profit in shorter time by doing this aquaculture technique.

The mud crab will be nurtured inside pond which have around 0.25 hectare to 0.2 hectare with great tidal wave and the dept should be around 1 meter to 1.5 meter. The pond can be prepared to ensure that there is great quality lime as the foundation on the bottom of the pond. You can drain the pond for the preparation process then put bamboo mat on the bottom of the pond as well as fences on the boundaries. With these methods then the mud crab will not escape out of the pond since they usually dig their way out from the pond through the bottom of the pond. The mud crab aquaculture can also be done using compartment to ensure that the mud crab with different sizing will be separated. This is important to prevent the mud crab from attacking each other as there is also cannibalism going on in this crab.

Those are the techniques that you can use on the aquaculture of the crab. Both of those techniques can easily be done so you can start to do this aquaculture in smaller scale if necessary. Not to worry as the mud crab aquaculture profit will also be high even though the scale of your business is actually quite small. It is a great business for you to start and try as the profit is high.
