Kita akan dijemput

Di dalam hidup kita seharian
Ada persamaan inginan
Mencari harta sebanyak mana
Masa terdaya

Bila mentari menyuluh bumi
Kita pun bangkit dari mimpi
Menyambung semula pencarian
Yang terhenti semalam

Kepuasan terpancar jelas
Bila yang dimimpi terbukti
Dengan kekayaan yang dimiliki
Masih tidak lagi mencukupi

Memang begitu sikap manusia
Tidak puas dengan yang ada
Seolah harta di dunia
Bisa bawa ke sana

Kita terlupa harta yang nak di bawa
Amalan seharian itu yang mesti harus di hati
Sudah terlewat bila tubuh terbujur kaku
Tidak berfungsi... di saat itulah
Terlihat semua di mana
Tempat kita...

Harus diingat... kita hanya musafir
Yang didatangkan... hanya sementara
Menghunikan alam
Dan pasti akan dijemput... untuk pulang
Di jemput pulang

Bila diri ini disayangi

Terdengar bisikan mesra
Kalimah keramat bermentara
Bermulanya siang berakhir malam ku
Tak akan ku jemu menyebut namaMu


Tiada batasan waktu
Tiada tempat Mu tertentu
Di gunung di lembah, di darat, di air
Siapa pun hamba, keikhlasan doa, keagungan
Kasih merubah takdir

Bila ku sedari diri disayangi
Langkah kaki ini semakin berani
Bila terkeliru ku ucap namamu, terasa diriku
Kembali dipandu

Engkau pertama, tiada akhirnya
Aku dalam kegelapan engkaulah cahaya
Izinkanlah aku menumpang di sini
Di bawah naungan kasih dan sayang Mu
Ku berserah diri

RETENTION POND CARE

UNHEALTHY POND

Can be a financial liability
Accumulate pollutants
Produce algae blooms and odors
Require expensive dredging
Most pond maintenance techniques poison your pond to kill alga growths. Anyone suggesting the use of these chemicals or copper products should be asked if they would assume future cleanup costs associated with their use.

POND MANAGEMENT PROBLEMS

Excess Nutrient Levels

In pristine natural environments there is a wonderful, delicate balance achieved between animals, plants, and microbes.

For example,available nitrogen compounds are extremely scarce because all the nitrogen is locked away as plant or animal protein.

In contrast, retention ponds contain high levels of ammonia, nitrites and nitrates- often from lawn fertilizers. They also contain less plant life to absorb the extra nitrogen. The result is that free nitrogen compounds (which feed algae blooms) are common in retention, fish and farm ponds - in stark contrast to natural ponds.

Chemical lawn fertilizers are a major source of these nitrogen compounds, since they are highly water soluble and quickly wash into ponds. It is estimated that less then half of the nitrogen in chemical lawn fertilizers is absorbed by grass plants. While a typical chemical fertilizer may be over 20% water-soluble, a good organic lawn fertilizer would be about 1% water-soluble. Animal wastes(from birds, waterfowl, and fish), and decaying organic matter (like leaves and grass clippings) also contribute nitrogen to ponds.

How does Nutrient Reduction help reduce algal blooms?

Algal blooms in nature are minimized by reduction of free nutrients. This is the best approach to retention pond management. It is the only approach that addresses the source problem of nutrient overload.

Nitrifying bacteria belong to the family Nitrobacteraceae. Nitrosomonas (ammonia-oxidizers) and Nitrobacter (nitrite-oxidizers) are the most common. They require oxygen and can feed on inorganic nitrogen sources, such as lawn fertilizer. The use of these bacteria results in reduction of nutrients to levels which do not sustain algal growths. These bacteria are found in nature but not in sufficient numbers in retention ponds.


What about Oxygen and Pond Aerators?

When bacteria have available oxygen, they can produce roughly eighteen times as much energy as when they lack oxygen. Pond aerators increase bacterial activity but do not replace bacterial nutrient reduction.


How does this approach differ from Copper or Chemical treatments?


Copper produces a cheap, quick, temporary remedy for unbalanced ponds. But, these products do not address the real problem of nutrient overload. Therefore, the algae quickly bounce back. Copper products and chemicals also add heavy metals and pollutants into the environment, and are already banned in many states. Also,being an element, copper does not break down but accumulates.

Other Pond Problems Include:

Pesticide runoff from lawn care
Petroleum products from automobiles
Substances poured into garage and storm sewer drains
Accumulation of sludge concentrates many of these toxins in pond bottoms



What about Sludge?

Sludge forms in unhealthy ponds because they lack the microbial life needed to decompose organic matter. Pollutants like heavy metals, copper, pesticides,petroleum products, etc. accumulate and concentrate in sludge on pond bottoms. As pollutants concentrate in this sludge, they become more toxic, further damage microbial activity,decrease oxygen levels even more, and accelerate sludge buildup. Copper products also kill the beneficial bacteria that break down sludge.

Decomposition of this sludge is a focus of our pond treatments. Eliminating pond sludge reduces concentration of pollutants in retention ponds, a major concern of the EPA, and increases oxygen levels.

Pond Management by Bioaugmentation and Bioremediation


The balance that nature achieves in natural environments cannot be duplicated in retention ponds because of the concentration of lawn care products and other environmental influences.

However, a process called bioaugmentation can achieve another biological balance, which also reduces free nitrogen compounds. Bioaugmentation uses concentrated blends of natural bacteria for removing excess nutrients, and associated problems(like algae), from a damaged pond or lake.

We use only safe and natural products to improve the quality of pond and lake water. We use specific Microbe strains that have been isolated for their ability to perform highly specific, beneficial functions. Bioremediation uses multiple strains of bacteria and enzymes that biodegrade a large number of pollutants

Certain bacteria strains excel in nutrient reduction, which results in the elimination or minimization of algal growth. Some break down petroleum products. Other bacteria reduce suspended particulate matter and organic sediment, reducing bottom sludge. Enzymes are catalysts that increase the variety of pollutants that can be decomposed and aggressively breakdown pond sludge.

TIRAM BUSUK

Seorang pengusaha tiram menunjukkan tiram yang mati kerana pencemaran air Sungai Muar

150,000 benih sedia dituai mati kesan banjir

MUAR: Hasrat 14 penyelam tiram Sungai Muar untuk menuai hasil tiram diternak tidak tercapai apabila kira-kira 150,000 benih tiram yang sedia dituai ditemui mati dalam sangkar dipercayai kesan banjir teruk yang melanda daerah itu.

Banjir itu juga dikatakan turut menyebabkan banyak benih tiram di dasar Sungai Muar mati akibat dipenuhi air lumpur yang dibawa banjir.

Pengerusi Kumpulan Pengurusan Sumber Perikanan Kumpulan Nelayan Parit Tiram, Kapten (B) Jelani Laham, berkata sumber benih tiram di dasar Sungai Muar itu perlu mengambil masa sekurang-kurangnya enam bulan untuk pulih tetapi kemungkinan besar keadaan itu akan mengambil masa lebih lama untuk pulih.

Katanya, situasi sama pernah dialami penyelam kawasan itu ketika banjir teruk melanda Johor pada akhir 2006 dan awal 2007 lalu sehingga menjejaskan pendapatan nelayan.

“Banjir teruk baru-baru ini menyebabkan kira-kira 150,000 tiram diternak dalam sangkar di Sungai Muar yang sepatutnya dituai hasil dalam tempoh dua minggu, mati menyebabkan kerugian dianggarkan RM120,000, sekali gus menyebabkan kerugian kepada penyelam tiram yang bergantung kepada hasil jualan tiram berkenaan," katanya.

Katanya, banjir teruk yang sering berlaku menyebabkan penyelam tiram terpaksa menanggung kerugian menyebabkan pihaknya merancang untuk mengadakan projek ternakan tiram di kolam bagi mengelak risiko tiram mati akibat banjir atau kesan lumpur.
Jelani berkata, Pangkalan Parit Tiram adalah antara lokasi kegiatan nelayan sungai dan laut tertua di daerah ini serta terkenal dengan pengeluaran hasil tiram bermutu tinggi sejak negara belum merdeka, malah mutu tiram yang dikeluarkan dikatakan antara terbaik di dunia.

Katanya, sehingga kini ada kira-kira 20 penyelam tiram masih aktif dengan tumpuan di kawasan berhampiran pangkalan itu walaupun sebenarnya tiram juga boleh diperoleh di kawasan hampir 20 kilometer sepanjang pesisiran Sungai Muar bergantung kepada jadual pasang surut air.

Beliau berkata, kegiatan yang dikatakan bermula sejak 1870-an itu memerlukan nelayan menyelam sedalam lebih lima meter untuk mengutip tiram di dasar sungai dengan menahan nafas antara tiga hingga empat minit.

“Bagaimanapun sejak pertengahan 2006 lalu, nelayan kawasan itu mula menjalankan penternakan tiram sebagai langkah meningkatkan lagi sumber pendapatan mereka dan sehingga kini beberapa kali hasil ternakan tiram berjaya diperoleh," katanya.

Penyelam tiram, Ahmad Buang Ahmad, 39, berkata beliau terkilan apabila semua tiram yang sepatutnya boleh dituai dalam tempoh dua minggu mati akibat kesan limpahan air banjir di Sungai Muar.

Katanya, benih tiram itu mati berikutan jumlah air tawar yang banyak dan lumpur disebabkan hujan lebat yang menyebabkan banjir.

Beliau berkata, benih tiram itu mula diternak dalam sangkar mulai Mei tahun lalu dan sepatutnya saiz tiram yang sesuai dituai hasilnya ialah pada minggu pertama Februari tetapi sebelum sempat dituai, banjir teruk mula melanda menyebabkan pihaknya terpaksa menanggung kerugian.

OYSTER

OYSTER POPULATION WIPED OUT BY RECENT FLOODS
Source: New Strait's Times World News 18/02/2007 14:32:33

The entire population of oysters at the mouth of Sungai Muar has been wiped out by the recent floods.

The farmers who raised them in cages along the 1km coastal belt from Parit Tiram to Jalan Ismail, and the part-time divers, are now without income from harvesting the oysters.

Breeder/diver Azman Hassan says it will take at least two years for the oysters to return to the river.

The 67-year-old said that before the disaster, at least 50 part-time oyster divers were bringing up the catch each day.

He said Muar is known for two types of oysters - one from the Muar river and another variety found among coastal rocks, harvested by the women with hammers and chisels.

Muar oysters are in demand, he said, because they are believed to cure gallstones, and because they are sweeter and more succulent than oysters from other areas.

The shells are also used to make decorative items but at the moment, the sale of shells has been stopped. They are being dumped back in the river to encourage the oyster spate to grow, said Azman.

He said oyster farming along the Muar river began last July and was a huge success.
But the floods destroyed over a million oysters in 5,000 cages, causing an estimated loss of RM140,000.

He said the farmers plan to try again when the water in the river gets back to normal.

Even restaurant owners are feeling the pinch, as many of their customers refuse to eat “imported” oysters. Not only are they more expensive at RM14 to RM16 per kilogramme, but also lack the unique flavour and texture of Muar oysters.

Oyster-frier Lim Ah Hing says Muar oysters are touted as the best in the country.

Global warming and pollution could doom oysters
American Physiological Society
October 10, 2006

Oysters exposed to high water temperatures and a common heavy metal are unable to obtain sufficient oxygen and convert it to cellular energy, according to a new study presented at The American Physiological Society conference, Comparative Physiology 2006.

The study showed how cadmium, a heavy metal, reduces the oyster's tolerance of warmer water temperatures and makes it more vulnerable during the summer when water temperatures rise. Half of the oysters exposed to the pollutant in 28° C (82° F) water died within 20 days, said lead researcher Gisela Lannig. Oysters exposed to cadmium at lower temperatures showed much lower mortality rate, suggesting that the combination of high temperature and cadmium is more stressful than each of these conditions alone, she said.

The study "Temperature tolerance in the oyster, Crassostrea virginica, is affected by cadmium," was carried out by Lannig, of the Alfred Wegener Institute for Polar & Marine Research, Bremerhaven, Germany, and Jason Flores and Inna Sokolova, of the University of North Carolina at Charlotte. The work was done in North Carolina. The researchers presented the study October 10 during a poster session at Comparative Biology 2006: Integrating Diversity in Virginia Beach.

Oyster population decimated

Oysters once thrived in the coastal regions of much of the eastern United States, but over-fishing, global warming, rising ocean water temperatures and increased pollution have combined to reduce the oyster population to 5% of what it was 200 years ago, Sokolova said. The loss of oysters has far-reaching environmental implications.

"We can't even imagine the expanse of oyster reefs 100-200 years ago and their impact on the ecosystem," Sokolova said. For example, a century ago, the oyster population could completely filter the water in the Chesapeake Bay in three days. Today, with the oyster population continuing to decline from poor water quality and disease, it would take a year to filter the same amount of water, she said. In addition to filtering water, oysters create a kind of reef that other marine life depends upon.

"Studies have shown that there are more than 300 species reliant on oyster reefs, including at least 12 species important for their commercial or recreational value, such as blue crabs, sheepshead, croaker and stone crab," Sokolova said. "Some of these species, such as blue crabs, use oyster beds and reefs as nursery areas and as feeding grounds." The oyster beds are also important to a variety of marine life that serves as food for larger fish. It was within this context that the North Carolina team did their study.
