| Produksi Naik 353% 40% Lahan Tambak Direvitalasi Posted: 11 Mar 2010 05:26 AM PST
Pemerintah akan merevitalisasi 180 ribu hektare (ha) atau 40% dari total lahan tambak di Tanah Air, karena sudah tidak aktif lagi. Revitalisasi itu merupakan salah satu strategi pemerintah untuk menjadikan Indonesia sebagai negara penghasil ikan terbesar di dunia pada 2015 serta mencapai kenaikan produksi ikan 353%. " Revitalasi akan dilakukan di lahan-lahan pertambakan yang pernah menjadi primadona, namun ditinggalkan akibat penyakit yang sempat melanda beberapa daerah tambak di Indonesia. " ujar Direktur Perbenihan Ditjen Perikanan Budidaya Kementerian Kelautan dan Perikanan (kkp) Ketut Sugama di Jakart, rabu (10/3). Saat ini, menurut Ketut, sudah ada 1.000 ha lahan tambak di Jawa Timur yang diinvestarisasi dalam jangka waktu satu tahun, inventarisasi lahan tambak itu akan berlanjut ke wilayah potensial lainnya seperti Sulawesi Selatan, pantai utara (pantura) Jawa, dan Nusa Tenggara Timur (NTT). " Realisasi revitalisasi lahan pertambakan ini direncanakan rampung dalam lima tahun sesuai dengan masa jabatan menteri perikanan dan kelautan. Kami akan merevitalisasi lahan-lahan yang ditinggalkan akibat penyakit," tutr dia. Ketut menambahkan, untuk merevitalisasikan program tersebut, KKP sudah mendapatkan dana dari APBN. Dan ini kemudian digunakan untuk memberikan bantuan kepada para petani tambak yang gagal memberdayakan tambaknya kembali berupa benih, perbaikan kolam, dan pelatihan wirausaha. Sementara itu, Direktur Produksi Ditjen Perikanan Buddidaya KKP Iskandar Ismandji mengatakan, untuk meningkatkan produksi selain melalui revitalisasi lahan, pemerintah akan lebih menekankan pada intensifikasi. "Pertanian tambak tradisional juga akan ditingkatkan dengan polikultur, yaitu membagi satu wilayah tambak, sehingga mampu menghasilkan tiga jensi produksi," tutur dia. Produsen Terbesar Dunia Menurut Iskandar, pemerintah menargetkan pada 2015 menjadi negara penghasil ikan sebesar 353% pada 2015 dibandingkan tahun ini. "Dari produksi ikan di Indonesia, yang masih menjadi primadona dari segi harga adalah udang," papar dia. Iskandar menambahkan, produksi udang pada 2009 sempat menurun menjadi 350 ribu ton akibat serangan penyakit di beberapa wilayah di Indonesia Tahun ini, pemerintah menargetkan kenaikan produksi sebesar 50 ribu ton menjadi 400 ribu ton.

| Percantik Rumah dengan Akuarium Posted: 11 Mar 2010 05:10 AM PST
Saat ini kehadiran akuarium sudah semakin diperhitungkan. Keberadaannya tak hanya mampu menenangkan jiwa, tapi juga bisa membuat rumah tampak lebih cantik dan menarik. Menurut arsitek Rosi Rahadi, sebenarnya sudah sejak lama keberadaan akuarium di dalam rumah diperhitungkan. Selain karena efeksensasiasinya yang bening, kegiatan "penghuni" akuarium yang dinamis, juga sanggup membuat suasana ruang menjadi tidakkosong. Tempat tinggal ikan hias itu memang kerap dianggap mampu mengubah ruang yang masih menjadi lebih "hidup". Namun, hal tersebut bisa saja tidak terjadi tatkala si empunya rumah kurang memahami tata cara peletakan akuarium agar tak merusak estetika ruangan idealnya, letakkan akuarium di tempat-tempat yang regarif, dalam arti tempat-tempat yang kurang memliliki aktivitas. Atau, kita juga boleh memanfaatkan akuarium kecil berbentuk sepermpat bola, lalu ditempel di dinding. Biasanya akuarium itu diisi seekor atau sepasang ikan saja. Peletakan sudah tepat, kini tinggal mrmikirkan tata percahayaannya karena akuarium juga memiliki fungsi penerangan ruang.Ya, akuarium dapat dimafaatkan sebagai alat penerangan buatan untuk bagian yang gelap dan kekurangancahaya alami, atau dijadikan alat penerangan pada ruang yang kerap digelapkan saat penghuni rumah sedang tidur, semisal ruang tamu dan ruang keluarga. Efek cahaya merupakan salah satu elemen pendukung akuarium yang bisa mengubah tampilan ruangan menjadi lebih menarik. Caranya, sebut Rosi, letakan lampu akuarium seolah-olah tersembunyi atau tidak terlihat secara langsung. "Jadi.lampu itu gunanya untuk menjadikan akuarium bagai memiliki cahaya sendiri.atau dengan kata lain membuat akuarium menjadi bercahaya,"imbuh Rosi. Sesuaikan ukuran lampu dengan besar akuarium. Begitu pula dengan warna lampu, perlu disesuaikan dengan tema ruangannya, yang sekaligus berfungsi sebagai UV buatan bagi kelangsungan hidup penghuni akuarium tersebut. Cara kreatif lain, buat cahaya akuarium dengan meletakan lampu di langit-langit tetapi yang bisa tembus pandang keruang di bawahnya. Tipe Minimalis Kita tahu, bentuk dan ukuran akuarium cukup beragam. Ada yang berbentuk kotak, lonjong, persegi panjang, bahkan bulat seperti stoples. Sedangkan untuk ukuran yang kecil hingga paling besar. Ada pula akuarium yang hanya berukuran sebesar stpoles. Walaupun terlihat kecil, jenis stoples ini mampu mempengaruhi keindahan sebuah ruangan. Menurut Rosi, akuarium kecil ini sangat lazim digunakan pada hunian bergaya minimalis. Jenis akuarium ini bisa memberi efek pembeda dari elemen disekelilingnya. Sifatnya yang cenderung kontras dan transparan sangat pas diaplikasikan pada bagian ruang yang masif, sederhana, atau sepi. Efek ini biasanya timbul dari sesuatu yang kecil di antara yang besar atau sedikit. Itu merupakan salah satu teori dalam desain minimalis. "Yakni sesuatu yang kecil atau sedikit namun sangat terasa pada ruang yang sederhana. Letaknya pun bisa jadi tidak lazim." imbuhnya. Akuarium tipe minimalis biasanya menggunakan frame yang sederhana, bahkan bisa dibilang tidakmemiliki motif ataupun frame. Hal ini berbading terbalik dengan akuarium tipeetnik. Jenis akuarium ini sering menggunakan frame berbahan kayu berukir. Begitu pula akuarium berdesain klasik. Pada akuarium model ini frame yang digunakan memiliki lebih banyak detain. "Jenis akuarium etnik dan klasik dapat menggunakan tempat seperti halnya meja akuariu. Namun untuk gaya minimalis, teknik peletakannya lebih bebas," ujar Rosi. sumber : http://www.dkp.go.id budidaya ikan  |
| Koi Food Secrets to Raising Quality Koi Posted: 11 Mar 2010 04:37 AM PST
by: RC Moore Japanese koi are the most colorful and magnificent fish that you can keep in any fresh water environment. The different color and pattern variations associated with the different koi varieties can be like an artist painting on each fish. Even the white of the Platinum Ogon koi can be breathtaking. Especially for a fish that can grow to 30 inches and live to 50 years in the right environment. From the Asagi to the Utsuri, there are many factors involved in raising these magnificent koi. Many koi keepers have done all the right things in creating a koi pond large enough, with plenty of water movement and filtration to keep and grow large koi. They may buy quality Japanese koi that started out looking great, but as time goes by may loose koi to disease or have the colors seem to wash out. Many koi keepers overlook the importance of using a premium koi food that meets all the nutritional needs of their koi. It's like humans eating a diet of junk food and expecting to be trim and healthy and live a long life. Bentonite Clay The Japanese have spent many years developing the different breeds by careful selection and also developing their own formulas of food for the best growth, color, and health. The best koi in the world are grown in mud ponds in the fertile valleys of Niigata in Japan. The reason for this is because of the minerals present in the clay of these mud ponds that ad to the color and health of the koi. Dainichi is the only koi food that incorporates bentonite clay in their koi foods. Bentonite clay contains over 60 minerals and trace elements that aid in enhancing digestion and growth, as well as neutralizing metabolic toxins. Koi that have a poor diet will show up in the whites looking dingy, especially in the face where it will look more yellow than in the rest of the koi. You can also add bentonite clay directly to the pond water to help stabilize the water ph. Koi will ingest significant quantities of silt and other indigestible detritus from their natural environment which will act to bulk out the diet. Having gravel in the bottom of your pond gives a place for this silt and detritus to build up without having the turbid water that you would in a mud pond. It will also harbor worms and small crustaceans that the koi will feed on. Water lilies can be taken out of the pots and planted directly in the gravel adding to the ecosystem of the pond. High Protein The metabolism of koi reaches a peak at water temperatures of 75° F. During this time it is essential that they receive a high protein diet to aid in growth and color. They also need to be fed at least twice a day, three times is better. Koi do not have stomachs, and when their metabolism is high they forage constantly. Fish meal and krill for color are protein ingredients to look for in a high quality koi food. Koi Eat Plants There are a lot of people that will tell you not to put Japanese koi and plants together. Pet stores and internet articles suggest that koi will destroy any plants you put in your pond. Koi are omnivorous and need vegetable matter in their diet. A high quality koi food will contain spirulina algae which also enhances color. Since koi forage constantly it is good to grow a plant in your pond that will keep up with the appetite of the koi. Watercress is an excellent plant food source for koi. Watercress contains significant amounts of iron, calcium and folic acid, in addition to vitamins A and C, and koi love it. It is best to plant on a shallow ledge with rocks around it to keep the koi from pulling up the roots. You can buy it in the produce section of your grocery store. Just stick it in some shallow water in gravel and it will grow. Different Foods for the Seasons During the cooler seasons of spring and fall it is best to feed a food that is higher in vegetable matter, lower in protein, and easy to digest. In the summer months, when the water temperature is above 70° F switch to a higher protein formula. When the water temperature is above 70° F it takes about 16 hours for the food to move completely through a koi digestive tract. At 50° F it can take up to 60 hours and food intake is much less. Only feed the koi as much as they will eat within a few minutes. It is much better to feed 3 times a day in the summer months. At 50° - 55° feed 2 - 3 times a week. When the water temperature goes below 50° F do not feed the koi at all. If the food is not digested due to the low metabolism it can rot in the gut of the koi and cause death. Cost Versus Quality If you consider the cost of a high quality food versus the "cheap" foods, there is not that much difference. Keeping healthy koi using a high quality food means fewer outbreaks of disease and lower mortality rates. You are not spending money replacing koi or treating for disease with medications due to poor health because of a poor diet. You also have to go by weight and not just the physical size of the bag. Cheaper foods tend to be more airy while the premium foods tend to be more dense, so it looks like you are getting more food than you actually are with the cheap food. Many times, if compared by weight, the price is pretty close. In the long run it may actually be cheaper to buy the premium food. You will definitely notice the difference in the color, growth, and overall health of the koi over just a short time.

| Aquarium Supplies Part 2 - My First Experience With Goldfish Posted: 10 Mar 2010 08:40 AM PST
by: Jonathan Wangsa If you are seriously considering keeping fish as pets or are just starting out, I would like to stress again the importance of having some basic knowledge about aquariums and fish keeping in order to enjoy the hobby for a significant length of time and to avoid frustrations and disappointments. In the first article I illustrated this by sharing my own childhood experience with bettas, and now I shall share my experience with goldfish. While I still had my bettas I also wanted to keep some goldfish since I also found them attractive and interesting. My mom was reluctant to buy me some since I already had the bettas but she finally gave in and bought me a pair of "telescope" goldfish. At the time I didn't have a real aquarium yet so we put the goldfish in a large jar (about 1 gallon). One of our neighbors told us that goldfish wouldn't tolerate chlorine and therefore, we should not use tap water. They happened to have a well and offered to let us use the water for my goldfish. I soon noticed that the fish were constantly gasping for air at the surface. They also refused to eat. After a couple of days the water started to become cloudy, so I changed it totally. However, the fish still refused to eat and continued to gasp for air. Not long after that they became lethargic and eventually died. My mom said probably "telescope" goldfish just weren't hardy enough and not easy to keep. However, I had not given up on goldfish yet, so I asked if I could try to keep other kinds and hopefully would have better luck. My parents eventually consented but my dad suggested that I get a real aquarium instead of putting the fish in a jar. You can imagine how elated I was that finally I was going to have a real aquarium. So we went out and bought a 10 gallon aquarium and a few goldfish at the same time. I believe we bought 4 fish: a couple of medium sized "comets" and a pair of "pearl scales." We didn't buy them at a store, though. It was more like a wholesale type of place where there were plenty of different sellers selling their aquariums and fish. Again, at the time neither my mom nor I knew much about fish keeping. So we didn't buy any supplies for the aquarium. Just the tank and fish. That was it! When we got home I filled up the aquarium with untreated tap water and immediately put the fish in. I was so excited to see the goldfish swim around in the tank, but that didn't last long. In a few hours the fish were no longer lively. They sort of stayed at the bottom and didn't move very much. When my dad saw them he said they probably lacked oxygen and suggested that we go out and buy an air pump to aerate the tank. I had only seen aerated aquariums in places like public aquariums and fancy restaurants and thought that an air pump had to be very expensive, but my dad said it would be OK. So my mom and I went to a fish store to look for an air pump. Besides the pump we also needed something to hook the plastic tube on to and hold it in place. We chose to get a frog ornament for that purpose (the air would come out of the frog's mouth). All the stuff didn't really cost too much. As soon as we got home we hooked everything up and air started flowing into the aquarium. Like magic, within a couple of minutes the fish started to "wake up" and finally became lively again. My dad said, "I told you so!" The air pump was about the only supply we bought for the aquarium. Having beautiful and lively goldfish in my very own aquarium was good enough for me. I loved them so much that I also fed them too much. I was happy to watch them eat. As you can imagine though, the water got dirty very quickly that I had to change it every day. One day a friend of ours told us that we shouldn't be changing the water daily since it wouldn't be good for the fish. Also, in the mean time I had read somewhere that if you wanted to use tap water you should set it aside for a few days to get rid of the chlorine. Therefore, I set aside a bucket of water and changed 3/4 of the water about every 3 days. I was able to enjoy the goldfish for a few months before one of them got sick and died and the others followed soon after. I was extremely sad and because of that my dad told me I couldn't buy any more fish. So, after all my fish died my hobby came to a sad end. Well, at least for a while. Again, there is a take-home lesson here: if you're serious about having your own aquarium, there's some basic knowledge you need to possess before you even buy the aquarium and fish. You don't have to know everything there is to know about the hobby, but at least for the sake of the fish, you should understand a few things (such as how many fish you can have in a tank, how much to feed them, what kinds of aquarium supplies to have, and what kinds of maintenance you need to perform, just to name a few) that are crucial to their well being. If you're an expert you most likely picked up on the things I did wrong in the story I shared above. If you're a beginner or just thinking about getting started with this hobby, I invite you to visit my web site (see below) to learn more.

bila ikan cupang anda kelihatan susah untuk berenang karena ekor menguncup satu dan ikan malas bergerak dan sering berada di dasar akuarium, kemungkinan besar ikan cupang tersebut terserang penyakit white spot atau penyakit jamur putih. Penyebab penyakit ini yaitu cendawan Ichtyophtirius multifilis. White spot bisa menyebabkan luka di sirip sehingga pada waktu berenang sering terlihat tersentak-sentak dan membenturkan tubuh ke dinding akuarium. penyakit ini sering timbul pada kualitas air yang buruk. Pengobatan ikan dilakukan selama 3 hari berturut-turut dan harus hati-hati agar semua sirip tidak rusak. langkah awal tambahkan garam dan tetrachicline dosis 0,5 g/l pada suhu air 26 derajat celcius. Pemberian obat jamur seperti Gold 100 dosis 1/3 sendok teh/liter air dapat dilakukan. kemudian diamkan cupang selama 8 jam sebelum dipindahkan ke wadah lain. Air dalam wadah harus diganti sebanyak 50% setiap hari dan tetap diberi obat anti jamur. budidaya ikan  |
