This fish is called Mujair because the first to discover this fish is Mr. Mujair in estuaries attack Blitar of East Java in 1939. Fish Mujair itself originates from African waters.

Tilapia fish growing very fast, this is certainly very good for the cultivation of tilapia fish. But as an adult growth acceleration is reduced. Mujair fish can reach 40 cm length. Mujair fish useful as animal protein supply.
If you lack the land and minimal capital, you can try fish farming Mujair with a tarp.
If using ground pool, you need to consider the location factor. The location is good for tilapia fish pond is as follows:

Tilapia fish

Good soil to make a fish pond is clay and does not pivot. Why? For this type of land can accommodate a large water and not leaking.
To facilitate irrigation pond by gravity for tilt between 3-5%.
Tilapia fish can grow normally, if the location of maintenance at an altitude between 150-1000 m above sea level.
Water must be clean, meaning there is contaminated by waste or toxins and not cloudy.
Perkambangan tilapia fish is very good if aira pool can continue to flow. Make this need in the channel and out of the water.
Good water temperature ranges between 20-25 degrees C.

Tilapia fish farming

Media preparation

In preparing this maintenance media, which needs to be done is draining the pool for a few days, then liming to combat pests and wild fish as much as 25-200 grams / square meter, given artificial fertilizer in the form of fertilizers, ie urea and TSP respectively with a dose of 50-700 grams / square meter, can also be added in the form of artificial fertilizer urea and TSP respectively with a dose of 15 grams and 10 grams / square meter.

Fertilization

Not only plants that need fertilizing, busisaya tilapia fish also need fertilizing. Fertilization is an aim to increase productivity and ponds, namely by stimulating the growth of natural foods as much as possible. Fertilizer commonly used is manure or green manure with a dose of 50-700 g / m².

Feed for Enlargement

If the level of Productivity and fertility to an already diminishing, then it could be given extra food with the following composition: 25% fish meal, 10% copra meal and fine bran by 65%. This ration composition used in fish farming commercially munjair.
Can also be given food in the form of pellets, which yield 20-30% protein with a dose of 2-3% of the population weight per day, given twice per day ie morning and afternoon. Besides, it is also the condition of the feed in these waters according to the dose or the existing provisions. That is in addition to the feed of the basic media also need to be given additional food in the form of pellets or crumbs crushed with a heavy dose of 10% of the population per day. Administration 2-3 times / day.
Actually feed muajir very easy. The rest of the vegetables in the kitchen, food scraps, leaves leaves etc.

Pest

Bebeasan (Notonecta)

• Dangerous for seed because of the sting.
• Control: pour kerosene into the water 500 cc / 100 square meters.

Ucrit (larvae cybister)

• Clamping bodies shredded fish with fangs up.
• Control: difficult to eradicate; Avoid organic materials accumulate around the pool.

Frog

• Eating eggs fish eggs.
• Control: often throw eggs float; catch and throw him alive.

Snake

• Attacking seeds and small fish.
• Control: do arrest; pool fencing.

Otter

• Eating fish at night.
• Control: berumpun trap pairs.

Bird

• Takes a light-colored seed such as red, yellow.
• Control: given the difficult barrier of bamboo in order to pounce; given tassel or rope barrier.

Disease
In general, things are done in order to prevent diseases and pests in tilapia fish farming:

Drying bottom of the pool on a regular basis after each harvest.
Pisciculture were completely free of disease.
Avoid excessive stocking of fish exceeds capacity.
The ideal water intake system is parallel, each pool were given a water intake door.
Feeding enough, both quality and quantity.
Handling during harvest or removal of seeds should be done carefully and correctly.
Animals such as birds, snails, fish thousand (lebistus reticulatus Peters) as carriers of the disease should not be allowed into the area perkolaman.

4 This is a rare species of ornamental fish in the world

Rare fish-admin information will give this time about the types of rare fish in the world. But not all the rare fish admin discussed here.

This fish is one type of food that most sought-after fish in South America, and consequently, its a big Pirarucu more than 2 meters is very rarely found in the wild now

Pirarucu have a fundamental dependence on weather surface for breathing. With the exception of gills, the fish has a swim bladder which resembles lung tissue, in order to allow these fish to extract oxygen from the weather created. This is an adaptation to the conditions in the plains of the Amazon, but Pirarucu will rise to the surface for hawa found within 5 to 15 minutes. Propensity for staying on the surface is this which makes it more vulnerable to attack from the fishing spear.

2. Freshwater Sawfish

Freshwater Sawfish

Freshwater Sawfish is one of predatory fish and sea fish which has been adapted along freshwater. These fish live in the sea-pacifik Indonesia, is Australia, Borneo, Papua, Vietnam, India, Madagascar and East Africa. This species is known to be living deep in the sector in rivers as well as lakes and ponds. Against the rainy period (December-March), these fish can live in freshwater rivers, while the dry period (May to October), this fish would prefer to live in the estuary or bay that resembles a sea habitat.

3. Napoleon

Napoleon

Napoleon fish is one of the great reef fish that live on the tropical regions. The length of this fish can reach 1.5 m. and many fish were able to reach a size of up to 180 kg to the age of 50 years. Animal life is the same average along other reef fish that live in a solitary way. One of the uniqueness of this animal is the circumference of eyes that will watch the direction of the point of view of up to 180 degrees. Most of these fish swim by means of their own foraging area near the reef, which in the form of food because many categories of mollusk and crustacean absolutely not least is the area less coral. This fish has a pattern of reproduction that hermaphrodite

Generally these fish that are born males and females will be turned into a time before adulthood. Napoleon did little fish are in Anambas, Pulau Natuna Sea and the South China Sea less. These fish reef fish most expensive so that not a few were arrested by the fishermen and in exports to outside the country. The price of fish Napoleon was able to reach one million. The fishing make Napoleon fish as well as life support that promise. When this Napoleon fish has been cultivated by local residents.

The second mistake is too often feeding or less. Frequency of feeding the koi fish varies depending on the temperature of the pool water. The colder the temperature of the pool water, the slower the metabolism of koi body so that the frequency of feeding should also be reduced, on the contrary if the temperature of the pool water increases the body's metabolism of koi fish also increased so that the frequency of feeding are also increasing.

The third mistake is to change the feeding with different brands abruptly. Replacing food with different brands need to be done gradually, by mixing with the old food. Mix food with the new food a little proportion, then increased until all switch to the new food. Span of approximately 7-10 days.

Certain types of foods should not be given to the koi fish and should be avoided. These foods include bird food, corn, peanuts, bread, rice and peas.

How Fast Cultivate Fish Nile Tilapia

Aquaculture Tilapia is a fish that growth and development biakannya faster than most other fish. Nilan fish can grow up to 1 kg per tail with meat tastes delicious. Tilapia is a favorite fish for fish farmers because of the relatively high resale value and at the same time rapid growth led to a shorter harvest time. Tilapia is also easy to cultivation, even fish can be cultured in a variety of ways to use the pool, floating net, or cages, in the fields, even in brackish water fish pond is able to grow and develop.

Nila Tilapia

HOW FAST cultivate fish Nile Tilapia

Breeding

Tilapia can reach adulthood at the age of 4-5 months and he will achieve maximum growth to give birth to aged 1.5 - 2 months. At the time he was more than 1 year about - about weighing up to 800g and this time he could issue a 1200 to 1500 larvae each time he spawn. And can last for 6-7 times a year. Before spawning male tilapia always make a nest in the bottom waters and territory will he guard and an own territorial area. Tilapia males become aggressive this season.

Tilapia fish eating habits

Tilapia are included in fish eating everything or Omnivore. These fish can breed with a variety of both animal and vegetable foods. Tilapia when he was a seed, feed plankton and algae, while if he is an adult he was able to be given additional food such as pellets and various other foods are taro leaves.

Things you need to know to maintain the tilapia are: growth of fish is highly dependent on the influence of physics and chemistry, and their interactions. At the time of heavy rainfall, for example the growth of a variety of aquatic plants will be reduced so that interfere with the growth of the water and indirectly interfere with the growth of tilapia. Tilapia will also be cepar growth if maintained in a shallow pool of water, because in a shallow pond plants and algae growth is faster than in a deep pool. There are others that pool at the time of manufacture using organic fertilizer or manure will also make better water plant growth and tilapia also be more rapid growth.

Male tilapia also has the advantage compared to the females. The males have a 40% faster growth compared to the females. Especially if maintained in an differentiated. Or monosex

Tilapia Hatchery

Land or pond for tilapia hatchery divided into two groups: the spawning ponds and pond. The ponds should be made with a strong dike, not porous (permeable), the height of the dike safe (at least 30 cm from the surface of the water), the water source of income guaranteed smoothness, and a spacious pool each - each 200 m2. In addition to note also the safety of pest predator fish such as water dogs, owls, cats and others, so it is recommended that in order perkolaman babas environment of high trees and shade, while sunlight was able to get into the pool.

Parent tilapia has an average weight of 300 g / head. ratio of females and males for spawning is 3: 1 with a stocking density 3 fish / m2. Shaped pellet feeding as much as 2% of the weight of biomass per day and is given three times a day. The parent fish should come from official agencies to conduct the selection and breeding of such prospective parent Freshwater Fisheries Research Institute Sukamandi, so quality is assured purity and superiority.

Parent female tilapia can be cooked eggs every 45 days. Every parent females produce larvae (newly hatched seed) at an early stage about 300 g of as much as 250-300 larvae. This number will increase until it reaches 900 larvae in accordance with the female parent weight gain (900 g). After completion of spawning in one cycle (45 days), the parent-rested and female parent is separated from the male parent

for 3-4 weeks and fed with protein content above 35%.

After two weeks of the maintenance period adaptasidi kolambiasanya-parent female parent started there were childless, generate larvae which usually remain in the care of the parent. Larvae were collected premises -larva diserok way drain wear made of fine fabrics and subsequently accommodated in Happa size of 2 x 0.9 x 0.9 m3. Collecting larvae done several times from the morning until the afternoon, and duusahakan larvae were collected one day the minimum accommodated in one Happa.

Seed Jantanisasi tilapia

To get the seeds single sex male tilapia (monoseks) then do jantanisasi process. For this purpose the necessary minimum of 24 pieces each Happa size 2 x 2 x 2 m3 were placed in a pool with an area of ​​approximately 400 m2 and a minimum of 1.5 m into the water. Into each hapa can be charged as much as 20,000-30,000 tails of fish larvae. Larvae feed in the form of flour that was mixed with 17 Alpha Methyl Testosterone hormone until the maintenance period for 17 days.

Larvae results jantanisasi process further maintained in the pond measuring 200 m2. Swimming previously had dried, mud dug, given chalk as much as 50 g / m2, and was given chicken manure fertilizer 250 g / m2. After liming and fertilization, the pool is filled slowly to a height of about 70 cm of water, flooded for 3 days, given urea and TSP respectively -masing as much as 2.5 g / m2 and 1.25 g / m2. After the pond filled with water immersion 7 days, the fish seed jantanisasi process incorporated with a density of 250 fish / m2. Supplementary feeding can be done with a special form of flour feed for fish seed. Remanuring with urea and TSP done once a week and with each dose of 2.5 g / m2 and 1.25 g / m2 pool and administered for pisciculture.

After a 21-day maintenance period, premises fish average weight of 1.25 g (size 3-5 cm length) can be harvested. To harvest tilapia fish nets should be used eret at the beginning pengankapan. When the number of fish in the pond is expected to stay slightly was drying the water.

How To Raising Tilapia

Fish has good durability during transported if his stomach empty and the water temperature is relatively cold media. Because it will be harvested and transported if the fish should not be fed at least 1 day. Freight using plastic bags, where one-quarter and three parts water per four parts contain pure oxygen or iced block size of 20 x 20 x 20 cm3 (ice blocks are in the water with the fish seed media). A plastic bag with a volume of 20 L can be filled with fish size 5 cm maximum of 1,500 head / bag, with a long period of tolerance in bags of about 10 hours.

Enlargement of tilapia in ponds

Enterprises enlargement of tilapia in ponds with monoculture systems, has targeted production for domestic and export markets.

For enlargement tilapia in ponds, which first performed is repaired pematangnya ponds, drains and doors water. Pond bottom mud is removed, the next pond drained, so all the pests that like to disturb the fish could be wiped out. Liming is done with a dose of 50 g / m2 and fertilizing with manure 250 g / m2. Then the pond filled with water to a height of 70 cm, after three days of fertilization with urea and TSP with each dose of 2.5 g / m2 and 1.25 g / m2. At the beginning of the water filling cultivated salt content of about 5 ppt and could subsequently be increased submarine maintenance period to 15 ppt.

Preferably stocked seed size + 1.25 g (length 3-5 cm) with uniform size and healthy characterized by bright colors, movements agile and responsive to the feed. To harvest the target average size of 15 g / head (+ 1 month), stocking density of 20 birds / m2. As for the target crop size of 500 g / head (+ 6 months of maintenance), density of as much as 4 shrimps / m2.

During this maintenance period fish were fed an additional form of pellets as much as 3% -5% per day of biomass, and provided with a frequency of three times a day, the feed must be qualified with a minimum of 25% protein composition (Appendix 2).

At the start of the maintenance, the water level is maintained at least 70 cm, and when the maintenance period has been reached two months the water level increased, so that by four months of height maintenance cultivated up to 1.5 m.

Remanuring with manure carried out once every two months with a dose of 250 g / m2, whereas urea and TSP remanuring done every week with each dose of 2.5 g / m2 and 1.25 g / m2 during the maintenance period.

With a production target size of 500 g or more per cow is especially needed for the production of fillets, then the maintenance period is about six months. Harvesting is done by way of end use nets disusur seser. When perceived population already live fish in a little pond, new water ponds dried. Cultivated fish catches must be fresh and vibrant. Selainitu, tilapia for export commodities is required to be handled more carefully especially from the aspect of hygiene and appearance of the product.

For local consumption generally fish with an average size of 200 g / m2 can already be marketed in the fresh state. In the process of storage, transport and marketing can use the ice as a medium to maintain the freshness of the fish.
