Hippocampus spp and Amphiprion sp

Because the love in the world's fisheries are membudidayakan make him some type of fish is threatened due to the population continues to be hunted in large numbers. That he, Ari Wahyuni or regular disapa Kadek. 

He successfully developed a sea horse (Hippocampus spp) and nemo fish (Amphiprion sp) in bulk. Sea horses have developed two types, namely Hippocampus kuda and Hippocampus comes. Year 2008, the total seed produced sea horse tails, and 30,000 seeds nemo fish around 10,000 head.

He then experiment with a pair of fish nemo basic color orange color with a bright line of black and white decorated siluet (Amphiprion ocellaris). Fish taken from waters of the Bay of Lampung, Lampung Province. Beginning of the experiment did not succeed. Nemo pair is even dead. 

Kadek buy again for the hundreds of fish nemo dikembangbiakkan. He also explore the concept of "home made" the perfect replacement for the nest coral reefs and the reef fish that lay eggs. The process of testing this caused hundreds of dead fish nemo. He then uses anemon sea to the nemo nest parent and create a pipe used as a modified residential nemo seed. 

"This is tersulit find a place to live, nest, lay eggs and fish. If the tercemar and damaged coral reefs, fish populations in natural easily threatened, "said Kadek, who works as a researcher at the Center for Development of Cultivation Sea (BBPBL) Lampung. 

Almost concurrently with the cultivation of nemo, he also innovate memijahkan which the sea horses are rare animals. Sea horse pemijahan results that have relatively fast growth period so that maintenance takes only 6-7 days to be ready to harvest size in the top 10 cm. Pemijahan horse sea in Indonesia have dirintis the 1990s by researchers BBPBL Lampung, Sudaryanto. 

As researchers, Kadek not want half. He is also seeking the right formula feed for horses and nemo sea through the provision of the type of feed is adjusted to the age of the species. Nemo the fish to feed on natural food mengonsumsi can be made pelet after measuring 3 cm. 

Pengembangbiakan nemo fish and sea horse reap results in 2008. Nemo fish are the offspring of the second generation, while the fourth generation of sea horses. Sea horse, which is the primary drug of its production to reach 14,000 head, including marketed to Japan and Germany. 

The seed of cultivation also has better resistance rather natural and can catch adapt to artificial feed, environmental changes, and salinity. In addition menekuni nemo fish and sea horses, Kadek with the research team also developed BBPBL Lampung cultivation Kerapu duck (Cromileptes altivelis) and seaweed. 

Own capital 

Graduate of the Faculty of Biology University of Satya Wacana, Salatiga, this sure is a sea fishery wealth of potential biological dibudidayakan. For researchers who are also civil servants (PNS), Kadek aware of research during this applied less to apply the community. 

Furthermore he criticize fish farming in the country charming is not yet developed, because attitudes tend to researchers who are reluctant to work harder to promote and reveal the wealth fishery country. 

As a proof of seriousness to develop research, Kadek dive time to pocket millions of rupiah for research nemo fish. Keteguhannya nemo research and raise the cost of government without the officer had time to reap the suspicion supervisory civil servants who do BBPBL Lampung in 2005. 

Supervisors Kadek suspect that use of funds "dark" and secretly do research nemo fish and sea horses. Once through the process of interrogation, the officer turned to support research conducted on self-reliance Kadek. 

Inspired nemo 

Wrestle with the cultivation of water animals make conscious women this often inspired attitudes and behavior of fish. He seemed to know when the nemo fish and sea horse is the animal that is faithful and just like the party is integrated. 

"Nemo trustiness Conference that I continue to be loyal to the (culture) of fish," said the sixth child of seven brothers that. 

Kadek not want to save the results of his work. He was long the place pembenihan back shrimp (hatchery) kolaps the property since 2003 to encourage farmers membudidayakan nemo and sea horses. 

He was principled, maraknya effort bombardment reef fish and hunting conditioning can not be stopped solely with restrictions and sanctions. Vicious circle destruction of the biota can be a solution when there is an alternative form of revenue for the community. 

To realize the hope that, Kadek register to finding the Forestry Department in order to obtain certification cultivation of sea horses. With the certification, the steps to expand cultivation of nemo and the big sea horse easier. 

"Cultivation of fish expected to be an alternative income for the community. This is better rather than bomb damage to coral reefs and fish population, "he said. 

This year he is committed memijahkan four other types of nemo, sandaracinos the Amphiprion, Amphiprion sebae, Amphiprion melanopus, and Premnas epigrama. In Indonesia there are 34 species of fish nemo fish that are decorative. 

According to him, one of the obstacles that must be solved is that the marketing chain is not completely sure. In which the price of fish farming is relatively low or dipatok with the haul, despite the results of fish farming have the endurance of life better. 

Selling price of Rp 3,500 nemo fish tail, much lower price rather than the export of 15 U.S. dollars per head. Meanwhile, sea horse Rp 10,000-Rp 15,000 per head, whereas the export price of 20 dollars 25 U.S. dollars per head. 

Without splitting the issue of marketing, fish farming efforts raised difficult to achieve.

High tides force closure of 5 fishing companies

Investors in these businesses had withdrawn capital because of worsening business conditions caused by the flooding, said Agus Wibowo, head of the legal and human resources division of Prasarana Perikanan Samudera company.  

High tides which have frequently flooded areas of Muara Baru, North Jakarta, have forced at least five fishing companies in the Nizam Zahman seaport to close their business. 

"And the global economic crisis has made things worse," Agus said on Sunday, as quoted by beritajakarta.com. Nizam Zahman seaport is home to 35 fishing companies, and five of them have been forced to close

Aquarium, fish draw shoppers closer

A little boy eagerly called his mom to come closer and to see some Angelfish (Pterophyllum scalare) in an aquarium.

The freshwater fish, originally from South America, were among many species on display at an exhibition at Pondok Indah Mall (PIM) 2, a plush shopping mall in South Jakarta. 

There were many fish like arowana, koi and clown fish, to name a few. 

The favorite, however, seemed to be a baby shark on display. This fish drew the attention of shoppers who were quite taken with the tiny predator. 

""At this size, the shark looks like a catfish,"" said a man to his colleague. 

It seemed that the organizer brought baby shark to the mall to draw the attention of more and more people. 

""We organized this exhibition with the hope that the industry in this sector will become more dynamic,"" said Ken Ken from the bimonthly magazine d'fishes which organizes the exhibition. 

Ken Ken, who describes himself as an amateur fish observer, said that while Singapore and Malaysia had regular fish exhibitions, Indonesia did not. 

He said that Singapore recently organized its regular fish exhibition called Aquarama while Malaysia had its own exhibition called Aquafair. 

""We hope this event will become a starting point for a regular exhibition in Indonesia,"" he added. 

For this maiden exhibition, d'fishes worked together with the marine and fishery ministry, the cultural and tourism ministry and some specialists on fish, aquariums and decorations. 

Nita from Aqualife, a company that focuses on aquarium design and fish, said that only few people know exactly how to keep fish well. 

She added that those who want to have fish at home need to spend time to take care of the aquarium. ""Taking care of freshwater and seawater fish needs different approaches,"" she said. 

Nita's colleague Yuni meanwhile said that people have to replace water regularly. ""How frequently people should replace the water will depend on the size of the aquarium,"" Yuni said. 

She said that people must not replace all the water in the aquarium at once but, rather, replace one-third of the water. 

""The best method is to replace water once in every two weeks,"" Yuni said. 

People can replenish freshwater from a tap. As for seawater, they can buy it from outlets like Aqualife. In fact, Aqualife provides anything needed to support this hobby, from fish or aquariums to regular maintenance. 

The specialty of Aqualife's aquarium is its material. Because it is made of acrylic, it is scratch-resistant. 

For those who consider shape very important, Aqualife offers aquariums in several shapes: rectangular, hexagonal and tubular. It also offers vertical aquariums which can be used to separate rooms in houses. The vertical aquarium with a motor to generate bubbles is priced at Rp 15 million. 

The unique curved aquarium can function as a bar table. This aquarium bar table is offered for Rp 50 million. 

Apart from Aqualife, there were some other companies that displayed their products to customers including Alam Tropika Aquarium, Oriental Koi, Aquanda and Shelook Red. 

""We not only exhibit fish but also aquariums and various other equipment. We can organize a better exhibition in the future,"" Ken Ken said. Source: The Jakarta Post , Jakarta | Sun, 09/23/2007 3:11 PM | Life

Precious Kalimantan wetland losing ground

Lake Sentarum National Park, frequently called the heart of Borneo, is the largest wetland ecosystem in Asia, covering 132,000 hectares of swamp and marsh. 

The park's existence is so vital that the zone has held a place on the Ramsar List of Wetlands of International Importance since 1994. The writer was invited by the Center for International Forestry Research (CIFOR) to visit the area. 

Located in West Kalimantan's Kapuas Hulu regency, the park is facing a gloomy future, threatened by a plan to permit oil palm plantations, water-greedy and homogeneous, to develop on its perimeter. The plan is now sitting on Regent Abang Tambul Husin's desk. 

The giant sponge serves many purposes. It retains water coming down the Kapuas River during the rainy season, then supplies that water to the area in the dry season, preventing aridity, and serves as West Kalimantan's major source of freshwater fish. 

Although people find little direct use for wetlands -- unnavigable, swampy, and unfit for cultivating standards food crops -- this terrain contributes a high degree of biodiversity of land and water biota. Wetlands also serve as a breeding ground for many species significant to humans. 

People who rely on fishing and fish farms for their livelihoods living near the park are concerned about the proposal to open up oil palm estates near the preserve. 

Hari Sudirman, a resident of Sungai Lalau village in Suhait district, said he feared it could put an end to his 15-year-old fish breeding business.now we have problems regulating our water needs," he said. 

He said he was aware the regent had not yet issued licenses for the project, which could turn over 18,000 hectares in Suhait district. 

Some of the 18 companies in the plan, however, have been bold enough to already start reclaiming land, he said. 

Premature development has also been observed in nearby Semitau district, Kapuas Hulu regency. 

A Selimbau community leader, Walidad, said he had been asked to attend a stakeholder meeting with residents, Selimbau district head Aband Sudarmo and employees of the oil-palm company. refused to put my signature because I disagree with the plan," he said. "It'll spoil the natural conditions and threaten the rare orchids near the Selimbau royal cemetery." 

Aband confirmed some 3,000 hectares in his district could host the new project. 

He said he was unaware of the size of the total area affected by the project across the regency and was only carrying out the regent's instructions to mediate between the company and residents. 

"The outcome here depends on the residents," he said. 

The national park's administrative head, Himawan Gunadi, said he had received letters from community groups opposing the oil palm plantations. 

He also said he would examine a map of the area affected by this plan, adding the park should be located far from any planned plantations, particularly as oil palm trees are water-consuming plants that should not be grown around the park. 

"Since oil palm plantations will only harm theenvironment, I hope the plan will not be implemented and be further reviewed," Himawan said. 

An ecologist from CIFOR, Elizabeth Linda Yuliani, who has been conducting research in the park for four years, said physical changes on the park's perimeter -- its contours, topography and spatial plan -- could alter Lake Sentarum's role in the water cycle. 

She warned such changes might reduce the rate of water flow, causing more mud to accumulate, and in turn lead to declines in the fish population. 

Monocultural plantations and intensive agriculture practices rely on pesticides and chemical fertilizer, which will also detract from the lake's water quality. 

"Based on our research, pesticides could harm at least 95 fish species in Lake Sentarum and then accumulate in the human population through water and fish consumption," Linda said. Changes to the water system, especially sedimentation and reduced water flow, could lead to the extinction of 89 indigenous fish species. 

The lake hosts 200 species of high economic value, including the super-red arowana (dragon fish) -- a freshwater species which lives in black-water rivers, slow-moving waters that flow through forested swamp, peatland and marsh. 

The water appears black because of the underlying peat, but it is clear and relatively free of sediment. 

If oil palm estates are opened around the park, 965.2 million hectares of peatland and 128 million tons of peat might be affected, a low estimate based on the regency's estate location map. 

Peatland provides efficient carbon reserves in addition to its role in mitigating the rate of water flow. Despite its role, peatland appears unproductive. Industrial developers see advantages to making peatland more productive by harvesting the peat and converting it to cropland. 

"The local forestry office has announced that eight of the 18 locations planned for oil palm estates have been granted survey permits," Linda said. 

She warned the Rp 34.7 billion annually earned by the community through fishing would be lost if the park's surroundings are turned into single-crop plantations which rely on intensive farming practices. 

A similar fate could also affect arowana breeders, who currently earn collectively between Rp 70 billion and Rp 145 billion annually.  

"Any monocultural plantation undertaking will change the natural setting, while oil palm and acacia trees are among the plants that cause the greatest water exhaustion."
