Ways of Breeding fish Tawes (Puntius javanicus)
The provision of quality seed in sufficient quantities and continuous is an important factor in the development of fish farming for consumption.
Effort is mostly done in Magelang District, as in the Village District Paremono Mungkid therefore supported the availability of good water during the dry season and rainy. Besides, it felt more rnenguntungkan hatchery operations because a relatively short time spent approximately three weeks - one month, and its marketing was easy.
tawes fish hatchery is there some way that hatchery fish in the ponds, hatcheries and hatchery in rice fields in the hapa. Here is a technique pembenihannya:
1. Holding elections
➢ To get good quality seeds and the number of lots in the hatchery Tawes need to choose a good parent with the characteristics:
a. Location of the anal opening is located relatively close to base of tail.
b. Relatively small head and pointed.
c. Large scales and regular.
d. Wide and solid base of tail.
Generally fish ➢ tawes males began spawning at age less than one year, and its parent tawes females at approximately age 1.5 years. To know that the parent fish tawes have matured genitals and ready to be cultivated with signs as follows:
a. Female parent
- His stomach expands towards genetal (release) if dirabalebih soft.
- Hole anal somewhat reddish in color.
- Close the gills when touched more slippery.
- When the abdomen massaged from head to anal direction will come out blackish liquid.
b. Male parent
When the abdomen massaged from head to anal direction will come out whitish colored liquid (sperm).
Close the gills when palpated feels rough.
- When the abdomen massaged from head to anal direction will come out whitish colored liquid (sperm).
- Close the gills when palpated feels rough.
2. Pond Preparation
Tawes spawning fish pond as well as a hatchery pond and the pond. Before used for spawning, pond dried.
Improvements constructed and the pond made elongated channel (caren / kamalir) of expenditure towards water intake of water with a width of 40 cm and depth of 20-30 cm.
3. Parent Waiver
The parent fish ➢ tawes who have been chosen to be cultivated later diberok, Pemberokan with the placement of the male parent and female separately for 4-5 days.
After diberok then inserted into the parent fish breeding ponds have been prepared.
➢ parent Submission to the pool when the water reaches approximately 20 cm.
➢ The number of the parent who removed 25 male and female parent male parent 50 tails.
➢ In the afternoon about 16:00 o'clock in the water entering the pond is enlarged so that the water flow faster.
Usually the parent fish ➢ tawes spawned at 19:00 to 22:00 o'clock.
➢ Parent will spawn normally have started at noon romp around the water intake.
4. Hatching Egg
➢ After tawes laying parent fish, the water entering the pond is reduced so that the eggs are not washed up, done at the hatchery spawning pond as well.
➢ In the morning checked if there are eggs that accumulate around the pool or the shallow part of the land distributed by swinging a broom stick in the bottom of the pond.
Tawes fish ➢ Eggs usually hatch all after 2-3 days.
➢ From the result of hatchery reared fish in the pond for approximately 21 days.
5. Fish Seed Harvesting
➢ Harvest conducted in the morning.
➢ dampen / drain the pond.
➢ After the seeds were dikamalir / dicaren, seeds are captured by the Waring or seser.
➢ The seeds are housed in hapa who have been placed in flowing water channel water flow is not heavy.
➢ Seed lersebut again later maintained in the pond or sold.
6. Separating
➢ At first pond dried for 2-3 days.
➢ Repair embankment, making caren / channel.
➢ Basic swimming analyzed using hoe, then fertilized with Urea & SP 36 10 gr/m2 and manure from 1 to 1.5 kg/m2 depending on fertility.

Best Way to Spawn and Breed Koi
Best Way to Spawn and Breed Koi
by: Jiyong Park
As a Koi owner, it makes you feel happy whenever you are breeding your own Koi. In addition, it also saves you money from having to purchase more Koi. But productive spawning and breeding takes skill and experience. Here are some guidance.
Koi regularly breed during the Spring and Summer seasons, especially when there is a full moon (most often, spawning and breeding come about at night) and the water temperature is the most constant. The necessary thing to do would be to pick out your mating pair.
Your mating pair must not be too young or too old or they give off inferior eggs and fries. The age range of the mating pair must be between 3 to 6 years old. Apparently, you would pick the pair that look the most flourishing and most charming.
If you are just starting out, try to take a pair of the same variety. This makes the whole process not difficult.
Approximately 3 to 4 weeks before mating season, part the mating pair into an alternative tank. You may possibly also decide on 2 males and 1 female if you wish. Make sure your mating tank is well aerated and you feed them graciously.
The female will begin to grow round as she carries her eggs in her body. She will emit a mating odor that will cause the male to try to spawn her. He does this by pushing her body against the side of the tank. As soon as she releases her eggs, the male will fertilize them with sperm.
The eggs are very sticky and will stick to anything at all. So it's practical to have spawning ropes to catch the eggs. When they are fertilized, remove the spawning ropes with the eggs or the adult pair would try to eat the eggs. Also, part the mating pair from each other for a day or two before bringing them back into your pond.
When the eggs hatch you will have hundreds of Koi fries.
Subsequently at least 4 weeks, you need to cull your fries to control their population. There are various ways of removing fries.
Alternative way is to give them away. Initially, check with your local pet store. Many pet stores have programs in which they will receive discarded animals and give them pleasant homes. Several may even pay a certain amount for each fish since they market them, but do not count of this. Local Zoos may also have programs.
If you know of a local Koi society, you may let them know that you have unnecessary fries. Instead, you can find a message board or group online and post messages there. You may even begin another person on a Koi keeping hobby.

Kiat Sukses Pembenihan ikan Tawes
Kiat Sukses Pembenihan ikan Tawes
Penyediaan benih yang bermutu dalam jumlah cukup dan kontinyu merupakan faktor penting dalam upaya pengembangan budidaya ikan untuk konsumsi.
Usaha pembenihan banyak dilakukan di Kabupaten Magelang, seperti di Desa Paremono Kecamatan Mungkid oleh karena didukung ketersediaan air cukup baik musim kemarau maupun penghujan. Disamping itu usaha pembenihan dirasa lebih rnenguntungkan karena waktu yang digunakan relatif singkat kurang lebih 3 minggu - 1 bulan, serta pemasarannya pun mudah.
pembenihan ikan tawes ada beberapa cara yaitu pembenihan ikan di kolam, pembenihan di sawah dan pembenihan di hapa. Berikut adalah teknik pembenihannya:
1. Pemilihan induk
➢ Untuk mendapatkan benih yang berkualitas dan jumlah yang banyak dalam pembenihan Tawes perlu dipilih induk yang baik dengan ciri-ciri:
a. Letak lubang dubur terletak relatif lebih dekat ke pangkal ekor.
b. Kepala relatif lebih kecil dan meruncing.
c. Sisik-sisiknya besar dan teratur.
d. Pangkal ekor lebar dan kokoh.
➢ Pada umumnya ikan tawes jantan mulai dipijahkan pada umur kurang lebih 1 tahun, dan induk tawes betina pada umur kurang lebih 1,5 tahun. Untuk mengetahui bahwa induk ikan tawes telah matang kelamin dan siap untuk dipijahkan dengan tandatanda sebagai berikut:
a. Induk betina
- Perutnya mengembang kearah genetal (pelepasan) bila dirabalebih lembek.
- Lubang dubur berwarna agak kemerah-merahan.
- Tutup insang bila diraba lebih licin.
- Bila perut diurut dari arah kepala ke anus akan keluar cairan kehitam-hitaman.
b. Induk jantan
Bila perut diurut dari arah kepala ke anus akan keluar cairan berwarna keputih-putihan (sperma).
Tutup insang bila diraba terasa kasar.
- Bila perut diurut dari arah kepala ke anus akan keluar cairan berwarna keputih-putihan (sperma).
- Tutup insang bila diraba terasa kasar.
2. Persiapan Kolam
Kolam pemijahan ikan tawes sekaligus merupakan kolam penetasan dan kolam pendederan. Sebelum dipergunakan untuk pemijahan, kolam dikeringkan.
Perbaikan pematang dan dasar kolam dibuat saluran memanjang (caren/kamalir) dari pemasukan air kearah pengeluaran air dengan lebar 40 cm dan dalamnya 20-30 cm.
3. Pelepasan Induk
➢ Induk ikan tawes yang telah terpilih untuk dipijahkan kemudian diberok, pemberokan dengan penempatan induk jantan dan betina secara terpisah selama 4-5 hari.
Setelah diberok kemudian induk ikan dimasukkan ke kolam pemijahan yang telah dipersiapkan.
➢ Pemasukan induk ke kolam pada saat air mencapai kurang lebih 20 cm.
➢ Jumlah induk yang dilepas induk betina 25 ekor dan induk jantan 50 ekor.
➢ Pada sore hari kurang lebih pukul 16.00 air yang masuk ke kolam diperbesar sehingga aliran air lebih deras.
➢ Biasanya induk ikan tawes memijah pada pukul 19.00-22.00.
➢ Induk yang akan memijah biasanya pada slang hari sudah mulai berkejar-kejaran di sekitar tempat pemasukan air.
4. Penetasan Telur
➢ Setelah induk ikan tawes bertelur, air yang masuk ke kolam diperkecil agar telur-telur tidak terbawa arus, penetasan dilakukan di kolam pemijahan juga.
➢ Pagi hari diperiksa bila ada telur-telur yang menumpuk di sekitar kolam atau bagian lahan yang dangkal disebarkan dengan mengayun-ayunkan sapu lidi di dasar kolam.
➢ Telur ikan tawes biasanya menetas semua setelah 2-3 hari.
➢ Dari ikan hasil penetasan dipelihara di kolam tersebut selama kurang lebih 21 hari.
5. Pemungutan Hasil Benih Ikan
➢ Panen dilakukan pada pagi hari.
➢ Menyurutkan/mengeringkan kolam.
➢ Setelah benih berada dikamalir/dicaren, benih ditangkap dengan menggunakan waring atau seser.
➢ Benih ditampung di hapa yang telah ditempatkan di saluran air mengalir dengan aliran air tidak deras.
➢ Benih lersebut selanjutnya dipelihara lagi di kolam pendederan atau dijual.
6. Pendederan
➢ Mula-mula kolam dikeringkan selama 2-3 hari.
➢ Perbaikan pematang, pembuatan caren/saluran.
➢ Dasar kolam diolah dicangkul, kemudian dipupuk dengan Urea & SP 36 10 gr/m2 dan pupuk kandang 1-1,5 kg/m2 tergantung kesuburannya.
➢ Setelah kolam dipupuk kemudian diairi setinggi 2-3 cm dan dibiarkan 2-3 hari kemudian air kolam ditambah sedikit demi sedikit sampai kedalaman 50 cm.
➢ Kemudian benih ditebar di kolam pendederan dengan padat tebar 10-20 ekor/m2.
➢ Pemeliharaan dilakukan kurang lebih 3 minggu - 1 bulan.
➢ Selanjutnya dapat dipanen dan hasil benih dapat dijual atau ditebar lagi di kolam pendederan II.
