Ikan pekasam goreng Allahyarham istimewa

PUTRAJAYA: “Datin Seri sangat ceria dan ketawa selepas pulang dari Hospital Putrajaya, tiba-tiba beliau sudah tiada, memang mengejut dan menyedihkan,” kata seorang pegawai di Unit Komunikasi Pejabat Perdana Menteri.

Katanya, mereka menghantar bunga dan kad apabila Allahyarham pulang semula ke Seri Perdana dari Hospital Putrajaya, petang Isnin lalu.

“Sebenarnya, kami amat rindukan masakan Datin Seri, beliau memang pandai masak dan itulah antara kata-kata yang kami tulis dalam kad itu,” katanya.

Antara masakannya yang turut digemari Perdana Menteri, Datuk Seri Abdullah Ahmad Badawi adalah ikan pekasam goreng.

Walaupun ikan terbabit dibeli tetapi cara Allahyarham menggoreng cukup istimewa dan menjadikannya begitu lazat.

Beliau yang menjadi antara pegawai Pejabat Perdana Menteri terawal tiba di Seri Perdana berkata, Perdana Menteri kelihatan cukup tenang.

“Ketika saya tiba kira-kira jam 8 pagi, saya lihat Tun Dr Mahathir berada bersama Pak Lah, beliau orang kenamaan dan kenalan terawal tiba,” katanya.

Beliau berkata, ketenangan Abdullah jelas ketara dan masih mampu mengarahkannya mengaturkan apa yang perlu sebagai persiapan pengebumian.

“Saya sangat sedih melihat keadaan Pak Lah, beliau cukup tenang, tetapi dalam hati Tuhan saja tahu,” katanya sedih.

Apapun, katanya, semua ahli keluarga Abdullah, termasuk mentuanya, Datin Mariam Abdullah berada di sisi ketika Endon menghembuskan nafas terakhir.

New Fish Species Studied for Aquaculture Potential by Aquaculture CRSP Researchers

By Dhirendra Prasad Thakur, Asian Institute of Technology

Climbing Perch (Anabas testudineus)

The climbing perch (Anabas testudineus) is a fish of tropical fresh waters of Asia and the Far East. The fish derives its name from the widely held belief that it can climb on trees, but this is actually a result of faulty observation.
A. testudineus is a very hardy fish. It is mostly caught from swampy and marshy tracts, as well as derelict pits, pools, and puddles that continue drying up during summer months. In its natural habitat, the fish can "walk" over dry land for some distance using its operculum and pectoral fins.
A. testudineus is in the family Anabantidae. It has an elongated body, with broad anterior and head, while the posterior is compressed. The dorsal side, and dorsal and caudal fins, are greenish to dark grey, while the belly, pectoral, and anal fins are pale yellow-colored. At the base of the caudal fin, a dark spot is present. A. testudineus is an obligatory air-breathing fish. In addition to four pairs of gills, it bears accessory respiratory organs‹one pair of labyrinthine and respiratory membranes within the suprabranchial chamber. The fish is highly esteemed for its fine flavor and prolonged freshness out of water. The maximum recorded length is 26 cm.
Seed of A. testudineus can be collected from nature or obtained under controlled conditions. A. testudineus is notorious for migrating and breeding into prepared carp nurseries. This habit is advantageously used for seed production. Gonad maturity in A. testudineus manifests with early rains, and the retrogression is noticed abruptly from September. Breeding takes place only after rain fully sets in and fills ditches. According to Besra (1997), breeding season lasts between the middle of April to the middle of June. In the laboratory, end of breeding was delayed as late as September. Induced breeding by hypophysation was successfully performed. Water temperature of 28 ± 1C and darkness were important environmental factors for successful spawning. A female weighing about 50 g produces about 20,000 eggs. Eggs float in an upside-down position at the surface. Feeding commences from the second day. Ciliates, flagellates, and other such minute zooplankton form the chief food of food of larvae at this stage. food or larvae at this stage.
A. testudineus is omnivorous but shows definite preference for insects. The scope of its natural food, however, is very wide. It can vary from a diet of filamentous algae to purely carnivorous. Pandey (1987) mentions that the alimentary canal structure indicates the fish has a tendency towards carnivorous and predatory habits. This fish feeds within the water column as well as on the bottom and has a short and slightly coiled intestine (Mookerjee and Majumdar, 1946).
A. testudineus can be cultured in monoculture, or in polyculture systems with Clarias batrachus or Heteropneustes fossilis or both. It can also be grown in composite fish culture ponds together with carps. Since the fish has a tendency to ³walk out² of ponds, dykes should be sufficiently steep (75 degrees or more) to prevent escape of the fish.

Climbing Perch, Climbing Bass
Anabas testudineus

SYNONYM: Amphiprion scansor, A. testudineus, Anabas elongatus, A macrocephalus, A. microcephalus, A. scandens, A. spinosus, A. variegatus, Antias testudineus, Lutjanus scandens, Perca scandens, Sparus scandens, S. testudineus

PHYSICAL DISCRIPTION: This oval-shaped species has large scales, and spiny rays on the dorsal fin. The body color is generally gray to brown, and occasionally a greenish iridescence is present. The iris of the eye may be orange.

SIZE: To 10" (25 cm)

HABITAT: Widespread from India to Southern China and Indonesia. This species inhabits a wide range of habitats including fresh and brackish water.


TANK: A tank measuring 32" (81 cm) with a capacity of 30 gallons (115 L) is sufficient for fish up to 6" (15 cm) in length. This species prefers shallow tanks with a cover of floating plants. Provide hiding places among rocks and wood. Most importantly, use a tight-fitting cover so this fish is not to go for a "walk" around your home.

WATER: pH 5.5-8 (7.0), 2-18 dH (, 73-88°F (23-31°C)

SOCIAL BEHAVIOUR: An aggressive species that should only be combined with other large, robust species. Smaller fish will serve as prey to this interesting fish.

SUGGESTED COMPANIONS: Possibly Ctenopoma species in a large tank, large Cyprinds, Knifefish, Mastacembelus, Polypterus, Giant Danios.

FOOD: Live; small fish, Tubifex, insects, insect larvae, small amphibians, crustaceans, chopped earthworms; lettuce; spinach; tablets; pellets; flakes; chopped meat; oatmeal; peas

SEX: Males have slightly longer anal and dorsal fins.

BREEDING: A spacious tank is needed for breeding. The pair should be fed with varied live foods in order to get them into spawning condition. The floating eggs are laid randomly. These should be removed, and usually hatch after 24-30 hours. Start feeding with Infusoria.

BREEDING POTENTIAL : Breeding is moderately difficult, in part due to the large tank requirement.

REMARKS: This species is famous for its survival capabilities and durability. At times of little food or water, this species will move overland, utilizing its labyrinth organ for breathing purposes. Many have reported that this species climbs small shrubs and fallen limbs at times. Often during the dry season, this species will burrow into the mud and remain dormant for extended periods. This species is considered a fine food fish in several countries.

DIFFICULTY OF CARE: 4. This robust, omnivorous fish is tolerant to many aquarium conditions. The drawbacks to this species include its quarrelsome, predatory nature, and the size that it can attain.

Climbing perch
Anabas testudineus

Climbing perch are declared noxious in Queensland. It is illegal to possess, rear, sell or buy climbing perch. Offenders face penalties up to $150,000. Climbing catfish have not established in Australia.

Climbing perch are pale brown-orange in colour to dark greenish-brown with occasional dark blotches over their body. Their pectoral fins become dark orange at the base. These fish are commonly seen at between 10 and 23cm, but can grow up to 25cm in length. Climbing perch possess an accessory air-breathing organ which enables them to survive in waterways that have low oxygen levels.

Climbing perch are native to Asia. They are a tropical fish and inhabit fresh and brackish waters throughout the world. Climbing perch are commercially fished throughout Asia as an important food fish and are considered a delicacy in some areas. They are not present in the wild in Australia.
These fish are most often found in canals, lakes, ponds and swamps. They are a hardy species and can tolerate extremely unfavourable water conditions (ie. low oxygen, extreme temperatures).

Climbing perch feed primarily on fish but also on macrophytic vegetation, shrimps and insects.
Climbing perch reach sexual maturity at around 15cm. Females lay approximately 50 to 100 eggs which float freely at the surface and are often laid in shallow, oxygen-depleted waters. The eggs are guarded until they hatch.

Environmental impacts
Climbing perch possess an accessory air-breathing organ allowing them to survive for extended periods out of water. In moist conditions they can survive out of water for several days or weeks, providing that their air-breathing organ is be kept moist. In drier times, they dig into the mud to survive. Climbing perch travel across land on their pectoral fins and, as their name suggests, may even climb trees. These abilities, as well as their highly developed predatory nature, indicate that this species presents a high risk for survival, dispersal and adverse environmental impact in Queensland waters. Northern Australia is particularly susceptible to this species establishing, as Papua New Guinea has had reports of climbing perch.
Climbing perch have not established in Australia, however if these fish are found in the wild or kept in aquariums, they should be destroyed immediately and reported to the Department of Primary Industries and Fisheries.
