Labeo rohita

Fig: Labeo rohita

Bengali name: রুই
Common English: Rohu 

Scientific name: Labeo rohita

Rohi or Rohu (Labeo rohita, Bengali: রুই) is a fish of the carp family Cyprinidae, found commonly in rivers and freshwater lakes in and around South Asia and South-East Asia. It is a herbivore. It is treated as a delicacy in Bangladesh, Nepal and the Indian states of Orissa, Assam, West Bengal, Bihar and Uttar Pradesh. It is called rahu in Nepali.In Hindi it is called rehu (rawas is the Indian Salmon, which is quite different). It is called rohi in Oriya, rui in Bengali, rou in Assamese and Sylheti, rohu it self in Malayalam, and is reared in Kerala. It is popular in Thailand, Bangladesh, northern India and Pakistan. It is a non-oily/white fish. During the early stages of its lifecycle, it eats mainly zooplankton, but as it grows, it eats more and more phytoplankton, and as a juvenile or adult is a herbivorous column feeder, eating mainly phytoplankton and submerged vegetation. It has modified, thin hair-like gill rakers, suggesting that it feeds by sieving the water.

Zebra fish

The zebrafish, Danio rerio, is a tropical freshwater fish belonging to the minnow family (Cyprinidae) of order Cypriniformes. It is a popular aquarium fish, frequently sold under the trade name zebra danio, and is an important vertebrate model organism in scientific research. It is particularly notable for itsregenerative abilities, and has been modified to produce several transgenic strains.

Distribution:

The zebrafish is native to the streams of the southeastern Himalayan region, and is found in parts of India, Pakistan, Bangladesh, Nepal, and Burma. The species arose in the Ganges region in eastern India, and commonly inhabits streams, canals, ditches, ponds, and slow-moving or stagnant water bodies, including rice fields. Zebrafish have been introduced to parts of the United States, presumably by deliberate release or by escape from fish farms.

Feeding :

The zebrafish is omnivorous. It primarily eats zooplankton, insects, insect larvae, and phytoplankton, although it can eat a variety of other foods, such as worms and small crustaceans, if its preferred sources are not readily available. Most zebrafish accept common food flakes and tubifex worms in the aquarium.

Bagarius bagarius

Bagarius bagarius, also known as the devil catfish, dwarf goonch or goonch (Bengali: বাঘাইর), is a species of catfish in the genus Bagarius. It is generally reported as being found in large and medium rivers in South and Southeast Asia, but considerable taxonomic confusion surrounds this species and B. yarrell.

Distribution: 

Bagarius species inhabit south and southeast Asia. They are distributed in the Indus drainage in Pakistan and India, east (including peninsular India) to the Red Riverdrainage in Vietnam and south throughout Indochina including the Malay Peninsula and Indonesia. B. bagarius is known from the Ganges River, Chao Phraya, and theMekong drainages, as well as the Malay Peninsula and the Salween and Mae Klong drainages and the Brahmaputra River and Ayeyarwady River. B. suchus originates from the Mekong and Chao Phraya basins. B. rutilus inhabits the Red River and Ma River in northern Vietnam. B. yarelli is widely distributed in southern and southeastern Asia.

Ecology:

B. bagarius inhabits rapid and rocky pools of large and medium-sized rivers. B. suchus is usually associated with rapids in the large rivers it inhabits. B. yarelli occurs in large rivers on the bottom, even with swift current, never entering small streams. It is found among boulders, often in the white water of the rapids where it apparently is indifferent to the strong current.

B. bagarius is primarily entomophagous. It also feeds on small fishes, frogs and shrimps.B. suchus, however, is a piscivore. B. yarelli feeds primarily on prawns but also eat small fishes and aquatic insects

Oreochromis mossambica

Local Name: Tilapia 

English : African mouthbrooder ,  Java tilapia ,  Largemouth kurper ,  Mozambique mouthbrooder ,  Tilapia ,  Kurper bream .

Tenualosa ilisha

Ilish (Bengali: ইলিশ Ilish Oriya: ଇଲିଶି Ilishii Sindhī: پلو مڇي Pallu Machhi Telugu: పులస Pulasa or Polasa), also spelled Elish, is a popular fish to eat among the people of the Indian sub-continent. 

 A tropical fish, it is the most popular fish with Bengalis and Oriyas, the national fish of Bangladesh and extremely popular in parts of India such as West Bengal, Odisha, Tripura, Assam and Southern Gujarat. Ilish also can be found in India's Assamese-, Bengali-, Oriya- and Telugu-speaking regions and in Pakistan's Sindh province. In Gujarat it is known as either Modenn or Palva.

Each year a large number of fish are caught in the Padma-Meghna-Jamuna delta, which flows into the Bay of Bengal

As Food : Ilish is an oily fish rich in essential fatty acids(omega 3 fatty acids)

Botia dario

The Bengal Loach, or Queen Loach (Botia dario) is a species of loach fish found in the hill streams of Bangladesh.

These fish are threatened by pesticide used in the cultivation of rice. Since 1997, the Bangladesh government has enforced strict penalties against polluters, with specific rules about the pollution of streams and waterways, so at least some preservation work is afoot.

Rank: Species

Higher classification: Botia

B. dario can be found in the creeks and streams of the northern and eastern regions of the country (bordering India and Myanmar, respectively), and is also known in India. The fish most likely populates the streams that supply the Bengal section of the Ganges river. B. dario is also reported in Bhutan, but only in the Gaylegphug river, which eventually drains into the far north of Bangladesh. In the aquarium: Botia Dario are good fish to have in tropical aquariums, quickly taking care of pest snail populations and less shy than Botia striata. They get as long as 6" and should be kept in groups of 4 or more. They are omnivores, and thus should be fed sinking pellets as well as algae wafers. They also enjoy fresh vegetables, such as cucumber, zucchini, and frozen foods like bloodworms and brine shrimp. Also, make sure to provide plenty of caves for hiding in.
