Malaysia: Caged fish breeders suffer major losses due to flood

13th January 2018;

The flood that hit the district early this month had not only caused damage to public and private properties, but also caused major losses to caged fish breeders here as they were left with thousands of dead fish.

Most of the breeders attributed the death of their fish to several reasons, including the strong river current on Jan 1 and 2 when the water level of Sungai Pahang began to rise.

Khaidir Ahmad, 55, from Kampung Tebing Tinggi, Lebak here, when contacted today said he suffered losses of more than RM33,000 after over 5,000 patin (Iridescent Shark Catfish) (Pangasianodon hypophthalmus) and Tilapia (Oreochromis spp.), as well as 300 kerai (Lemon-fin Barb) (Hypsibarbus wetmorei) fish, in his cages died during the flood.

He said the strong river current had caused the fish to suffer wounds as they were cornered and squeezed to the cage.

“The fish were also believed to have died due to the high turbidity level of the river which caused the fish gills to be covered with mud and deprived them of oxygen,” he said, adding that bacterial infection in the eyes and scales of the fish due to the deterioration in the water quality of Sungai Pahang was also believed to be the cause of death of the fish.

Meanwhile, Temerloh Fisheries Officer Shahidan Roslan said the Fisheries Department had taken samples from the live fish in order to determine the cause of death of thousands of caged fish of several breeders in the district.

He said the department had also informed the state Fisheries Department Bio-security Division, immediately after receiving a report on the incident.

Shahidan said initial inspection found that the death of patin and Tilapia fish was probably due to the strong river water pressure during the recent flood.

“The investigation revealed that most of the dead fish were found in the front area of the cage which might have received the high impact of the strong current,” he said.

Malaysia: Dead fish in Limbang river raises concern
21st May 2016;

Hundreds of dead fish were found floating along Limbang river since Thursday, causing concern among the public.

A factory worker at Buangsiul Road Mohd Azlan, 28 said ’lawang’ (buris) was among the species of fish seen floating in the hundreds in the river since early Thursday morning.

He said initially only a few fishes were seen dead but then the number increased at around 7am and 8am.

“This is very worrying although we are not sure what caused it.

"It could be the act of some irresponsible people and the authorities must investigate to prevent the incident from recurring and endangering both the aquatic life and people who could consume the dead fish sold in the open market,” he said.

Another worker Ling Jale, 48 estimated around 300 fishes of various species could be dead and floating from upstream.

“This is a very sad incident. Probably the fishes died of effluents from oil palm estates upstream that overflowed into the river due to heavy rain.”

Malaysia: Cage fish breeders incur loss of RM400,000 due to hot weather

29th March 2016;

Two breeders who reared fish in cages claimed losses of almost RM400,000 when their ikan patin (Iridescent Shark Catfish) (Pangasianodon hypophthalmus) and Tilapia (Oreochromis sp.) died two weeks ago, believed to be due to the hot weather.

Sabarudin Osman, 46, and Hamdan Ros Mat Derus, 53, who operated fish farming with cages in Kampung Herlang here, said this was the first time they experienced the death of such large quantities of fish since they started operating the fish cages in 1995.

“There have been cases of fish dying from the heat before this, but it was not as serious as this. Now, every time I want to visit the fish pond, my heart pounds because definitely I’ll find dead fish floating,” he said when contacted here today this.

Sabaruddin, who operates 50 cages of ikan patin and 40 fish cages of Tilapia in the downstream of Sungai Pahang, also did not rule out the possibility that he might be forced to temporarily shut down operations if the caged fish continue to die.

Meanwhile, in Tanjong Karang, three areas under paddy cultivation stretching 760 hectares located in Sabak Bernam, near here, have been identified to be affected by the El Niño phenomenon.

Integrated Agriculture Development Area (IADA) Northwest Selangor, managing director Eliyas Saad said the situation affects 380 farmers in Pasir Panjang, Sungai Leman and Sungai Nipah.

Malaysia: Thousands Of Fish In Sungai Bera, Serting Poisoned

9th February 2014;

Thousands of fish in Sungai Bera and Sungai Serting in the Bera area near here were found dead in the past week from poisoning or bombing activities by irresponsible individuals out to harvest fish.

This has threatened the livelihood of Orang Asli residents and settlers of the Triang Felda Cluster, who depend on catching fish from the two rivers for consumption and sale.

“They take advantage of the drop in the water level in the current draught season to harvest fish using poison or explosives,” said one of the Orang Asli residents, Deris a/l Panjang, 54, to Bernama, here, Saturday.

He said thousands of dead fish such as patin liar (wild silver catfish) (Pangasius sp.), baung (Mystus sp. catfish), lampam and kerai (barbs) (Barbonymus and Hypsibarbus sp., respectively) littered the surface of the rivers due to the illegal acts.

A settler from Triang Satu Felda, Ahmad Nazri Che Omar, 51, said, they dared not catch the remaining fish in the rivers fearing they could be poisoned and had resorted to seeking fish in nearby marshes for their own consumption.

Meanwhile, Kemayan assemblyman Mohd Fadzil Othman in urging the authorities to act against the culprits, also wanted the Village Security and Development Committee and the public to report to the authorities if they find out about illegal activities to poison fish in their areas.

Mohd Fadzil also advised the Orang Asli staying near the rivers against using water from the rivers for consumption as it could be poisoned.
