IKAN LAGA

Kenapa ikan laga mendapat sambutan??
Ikan laga mendapat sambutan yang menggalakkan ekoran kecantikan dan keunikan warna serta corak yang terlukis pada sayapnya dan harganya semakin tinggi sekiranya kedua-dua faktor tersebut semakin terserlah. Sayap ikan laga itu juga semakin menghampiri bentuk separuh bulan iaitu seperti kipas yang sangat cantik pada usia dua setengah bulan sehingga empat bulan iaitu tempoh yang paling cantik dan ditunggu oleh peminatnya.
Harga seekor ikan laga??
Harga yang paling tinggi yang pernah dicatat setakat ini, seekor ikan laga pada harga RM250 iaitu gred terbaik manakala ikan laga pada harga pertengahan pula mencecah sehingga RM100 hingga RM200.
Penjagaan secara komersial agak rumit.
Sebenarnya penjagaan ikan laga ini agak rumit dan cerewet terutamanya dari segi penjagaan air dan makanan yang merupakan dua aspek penting dalam memastikan peratus hidup anak-anak ikan laga tinggi. Air, contohya perlu digantikan dua hari sekali manakala makanan pula perlu diberikan sebanyak dua kali sehari.
Selain perlu memastikan kandungan air yang tidak terlalu banyak, ia juga perlu bebas daripada klorin sama ada menggunakan teknologi penapis atau ubat anti klorin yang boleh didapati di pasaran. Sekiranya menggunakan air paip biasa pula, ia perlu dibiarkan terlebih dahulu sekurang-kurangnya selama 2 hingga 3 hari sebelum boleh digunakan.
Makanan pula diberikan pada sebelah pagi dan petang sama ada cacing merah atau jentik-jentik. Cacing merah ini juga boleh didapati di mana-mana kedai ikan hiasan dalam bentuk tablet dan perlu dibasahkan dahulu sebelum diberikan kepada ikan laga. Bagaimanapun,  tidak diggalakkan ikan laga diberi makan pallet kerana ia boleh menjejaskan kualiti air.
Ikan laga jantan lebih cantik dan lebih besar daripada betina dan kebiasaannya proses mengawan akan berlaku sebaik ikan laga mencapai umur kira-kira tiga bulan. Untuk tujuan mengawan, ikan laga jantan dan betina akan diletakkan di dalam bekas yang sama selama kira-kira dua hingga tiga hari dan proses mengawan dipastikan berlaku apabila ikan laga betina menjauhkan diri dari ikan laga jantan.
Ketika ini, ikan laga betina akan diasingkan dan ikan laga jantan akan dibiarkan menjaga telur-telur ikan tersebut di dalam buihnya sehingga menetas iaitu kira-kira beberapa hari kemudiannya. Sebaik menetas anak-anak ikan itu yang berjumlah beratus-ratus ekor akan diasingkan bagi mengelakkan ia di makan oleh ikan jantan dewasa dan diletakkan di dalam bekas yang lebih besar.

Ketika proses bertelur!
Cara penjagaan dalam proses  pembiakan:
Ikan ini berkembang dengan cara bertelur dan telurnya melekat  pada substrat seperti akar tanaman, daun-daun atau serabut rapia.
Langkah-langkah yang perlu diketahui :
  1. Pilihlah induk yang baik dan jantan yang cantik dan agresif.
  2. Pisahkan antara induk jantan dan induk betina dan diberi makan yang cukup selama 4 s.d. 5 hari.
  3. Masukkan induk jantan dan induk betina kedalaman tempat pemijahan (toples, aquarium, ember, baskom) yang telah diberi tanaman air (eceng gondok atau serabut rapia dengan kedalaman air ± 25 cm).
  4. Setelah 2-3 hari akan terlihat telur menempel pada daun atau rapia.
  5. Pindahkan yang betina dan beri makan secukupnya.
  6. Selama 2-3 hari anak ikan tersebut tidak diberi makan karena masih ada persediaan kuning telur dalam tubuhnya.
  7. Selama 2-3 hari kemudian anak-anak ikan tersebut perlu diberi makan infosuria selama 3 hari kemudian diberi makan kutu air yang disaring selama 10 hari dan setelah itu dapat diberi kutu air tanpa disaring.
Induk ikan yang diberi makan cukup baik, setelah 2-3 minggu dapat dipindahkan kembali. Anak-anak ikan laga dapat dijual setelah berumur 2 bulan.

THE CLASSICAL ONE

MY HOBY

Cycling is one of the easiest ways to fit exercise into your daily routine because it's also a form of transport. It saves you money, gets you fit and is good for the environment.
It's a low-impact type of exercise, so it's easier on your joints than running or other high-impact aerobic activities. But it still helps you get into shape.
For example, someone who weighs 80kg (12st 9lb) will burn more than 650 calories with an hour’s riding, and tone their legs and bottom. If you ride up hills or off-road, you'll also work your upper body.
The best way to build your cardiovascular fitness on the bike is to aim to ride at least 150 minute every weeks. For example, you could cycle to work a few days a week or do a couple of shorter rides during the week with a longer ride at the weekend. You'll soon feel the benefits.

HOW TO BE GREAT TEACHER

So what makes a great teacher?

1) Passion for teaching. This can manifest itself so many ways. I'm the "jump around the room" kind of teacher, and sure, that comes from a lot of passion, but some of the best teachers I've known have had a passion that students had to be quiet to catch onto. For me, when I was a young teacher, watching people like Maura Gouck and Marijolin DeJager teach with their quiet passion and brilliance was so important to my development as a teacher.

2) Love of kids. You laugh, but it's true! I've seen people come in and talk about teaching and talk about how much they love their subject and know about their subject, but they never mention the kids. Worse, we had an interview once where the teacher clearly knew his stuff, but he basically admitted that his classroom management style was fear and intimidation. Not who I want teaching kids I care about.

3) Love of their subject. Again... pretty important. I spent four years dropping by Mike Thayer's classroom because to watch him explain physics or calculus was, for me, to understand how you could have a passion for something that was always a mystery for me. Great teachers not only love their subject, but they love to share that joy with students.

4) Understand of the role of a school in a child's life. High school is more than the sum of the classes the kids take. It's a time to grow, explore, try on identities, find joys that might just last a lifetime. Sometimes the best teaching we do happens on basketball courts, in the halls after a class, at a local coffee shop or in a drama studio. The best teachers know that they are teachers for much more than the time they are in the physical classroom.

5) A willingness to change. This one gets overlooked sometimes, I think. I've written about this before, but it bears repeating. We talk about how schools should be transformative for kids, but I think they can be just as transformative for teachers. If you expect kids to be changed by their interaction with you, it's got to be a two-way street.

6) A work-ethic that doesn't quit. It's a hard, draining job that will demand all that you can give sometimes. You've got to be able to have some balance in your life, but there are very few teachers who can be effective by cramming everything they need to do into the hours allocated by the average teacher's contract. (And for the record, the overwhelming majority of the teachers I've met put in hours well above and beyond the contract.)

7) A willingness to reflect. You've got to be able to ask why things went the way they did... both on the good and the bad days. And you have to be able to admit when the reasons it went bad were because of what you did, not what the students did. (Equally important is the understanding that often things go right because of what the kids brought to the table, not because your lesson plan should be bronzed.) Teaching requires a willingness to cast a critical eye on your practice, your pedagogy and your self. And it can be brutal.

8-) Organization. My personal Achilles heel, and one of the things I'm always working to improve. My Palm Pilot helped, really. But I hate paperwork and official looking documents, and it kills me. I am amazed at the people like Dale Lally who seem to get his papers handed back before the kids hand them in or seems to be able to put his hands on every unit he's ever taught within a moment's notice. Kids know what to expect, they know he's going to be organized and have a structure to his class... and he's still creative and spontaneous and interesting. I can only imagine how much better of a teacher I'd be if the structure of everything I did was just a little more organized.

9) Understanding that being a "great teacher" is a constant struggle to always improve. I'm starting my eighth year as a teacher in a little over two weeks. I'm pretty proud of what I've accomplished, and I think I've had some moments of great teaching in my career so far, but I also still see all the holes in my teaching -- sadly, often times mirroring holes in my self -- and I still want to get better... because I think I've got a long way to go to be a great teacher every day. And even if I get better at everything I see as weaknesses now, I can only imagine what new challenges will face me on that day.

10) Enough ego to survive the hard days. The tough days will leave you curled up under a desk, convinced that you can't teach or the world is too hard for these kids or the work is too much or whatever the problem was that day... you have to have enough sense of self to survive those days.

11) Enough humility to remember it's not about you. It's about the kids. If your ego rules your classroom, if the class turns into "me v. them" or if you can't understand that a sixteen year old might be able to tell you something you don't know, then don't teach. Or at least, don't teach high school.

12) A willingness to work collaboratively. Sure, there are some great teachers who close the door to their classroom and do what they want, but I think you send a strange message to the kids that way sometimes. Teachers are part of a school community, and even where that community can be flawed (and lots of schools are), a great teacher should be willing to work to make the community a better place.
