5 Bangladesh is one of world's most densely populated countries, with its people crammed into a delta of rivers that empties into the Bay of Bengal. Poverty is deep and widespread, although Bangladesh has made progress in reducing population growth and improving health and education. The country is vulnerable to flooding and cyclones. The major employer is agriculture, but it is unable to meet the demand for jobs. Formerly East Pakistan, Bangladesh came into being only in 1971, when the two parts of Pakistan split after a bitter civil war which drew in neighboring India. Bangladesh spent 15 years under military rule and, although democracy was restored in 1990, the political scene remains volatile. Analysts say the antagonism between the Awami League, which governed until two terms and the Bangladesh Nationalist Party reflects personal animosity between their leaders rather than substantial ideological differences. Bangladesh is a country striving towards prosperity despite various constraints. The country side is endowed with enchanting scenic beauty of greenery in vast alluvial fertile plain of deltaic terrain. While rivers criss-cross the mainland, sunny beaches run in long trail on the coast. The colourful tribal life on the hills adds to the richness of the land in variety.

22 1. The DLS is responsible for preventing the introduction or spread of diseases affecting aquatic animals. 2. The DLS is recognized by the World Organization for Animal Health (OIE) as Bangladesh s authority for aquatic animal health. Reportable aquatic animal diseases pose significant risks to animal health and to the Bangladesh economy. 3. If any entrepreneur or farmer work with aquatic animals and suspect or detect an aquatic animal reportable disease, he has the legal obligation to immediately contact a DLS officials.

23 While all disease response situations are different, the steps involved in an aquatic animal disease response normally include: 1. initial inspection; 2. sample collection and submission; 3. investigation; 4. disease confirmation; 5. destruction/disposal; and 6. cleaning and disinfection.

24

25 1. Once the DLS is made aware of a suspect case, a DLS veterinarian will visit the premises to assess the health status of the aquatic animals. 2. Samples are necessary when the DLS veterinarian makes a risk assessment and suspects a reportable aquatic animal disease. 3. If the animals are not exhibiting clinical signs or if there is no other evidence to support suspicion of a reportable disease such as a test from a private or district lab, testing would not be required.

26

27 The collection, handling, transportation and storage of the samples is carefully monitored and recorded. That is why the Lab will only accept samples that have been collected by a DLS veterinarian. This information is critical to ensure that test results are reliable and valid according to international standards. Following the sample collection, the DLS veterinarian may decide to place a quarantine and / or declare the premises infected to control the potential spread of disease.

28

29 The DLS veterinarian begins an investigation by asking a series of questions about the health of the animals and the management practices used at the facility. DLS staff may need certain documents to help in their investigation. These documents may include: veterinary records and laboratory reports; a detailed description of facility management practices; records of purchase / sale of feed, animals, etc. visitor logbooks; contact information for the facility veterinarian.

30 Testing to confirm if the aquatic animals are infected is conducted at a FDIL/CDIL/DVH Laboratory using internationally accepted testing protocols. There are a variety of tests that are used throughout the investigation. In some instances, a rapid response test is used. Other testing methods that may be required to confirm a reportable aquatic animal disease include RT-PCR and virus isolation through cell culture.

32 Bacterial disease: Bacteriemia (Haemorrhagic septicaemia) CAUSATIVE AGENT Aeromonas hydrophila,pseudomonas fluorescensand possibly others COMMON SYMPTOMS Shallow ulcerations, haemorrhages and in severe cases the abdomen is swollen and the scales protrude. Internally the body cavity is filled with opaque fluid, and sometimes haemorrhages over swim bladder. TREATMENT MEASURES Over crowding, and oxygen depletion are some of the contributing conditions that must be avoided. Terramycin (oxytetracycline) with g/100 kg body weight/day for days. 7.5 g/100 kg body weight/ day for 2 3 weeks. Pond 5 ppm of potassium permanganate is also a practical approach.

33 Columnaris disease CAUSATIVE AGENT Flexibactercolumnaris COMMON SYMPTOMS Lesions on the head, back and gills. The lesions start as small raised whitish plagues with a reddish peripheral zone and develop into large haemorrhagic ulcers. TREATMENT MEASURES Dipping in 500 ppm copper sulphate for 1 2 minutes; Adding 10 ppm to pond water; Terramycin with mg/kg fish/day. Pond 4 ppm potassium permanganate.

34 Fungal diseases: Saprolegniosis Causal Agent Saprolegnia spp. COMMON SYMPTOMS Ulceration of the skin, fin erosion, exposure of muscles and jaw bones and in some cases tufts of minute white hair like outgrowths may occur in the affected regions. TREATMENT MEASURES Dip treatment in 3% common salt solution or in 500 ppm copper sulphate solution or in ppm of potassium permanganate solution. Swabbing with 10,000 ppm of potassium dichromate is also recommended.

35 Fungal diseases: Branchiomycosis CAUSATIVE AGENT Branchiomyces spp. COMMON SYMPTOMS Characterized by necrosis in the gill due to intravascular growth of this fungus. Histologically hyperplasia, fusion of gill lamellae and areas of acute necrosis are seen. TREATMENT MEASURES Improvement in water Quality, avoidance of over feeding and manuring; and addition of freshwater are quite effective. Draining and liming the pond or treatment with bleaching powder is essential before initiating the next culture operation.

36 Fungal diseases: Myxosporodiasis CAUSATIVE AGENT Myxobolus sp. COMMON SYMPTOMS Presence of white cysts of varying diameters on the body, fins, gills, opercula etc. In some cases, emaciation, dark colouration together with presence of cysts and spores in kidney tissues without showing external cysts. TREATMENT MEASURES Infected fish should be immediately removed from the pond. Before initiating the next culture operation the pond should be dried if possible and/or thoroughly disinfected with bleaching ppm. Provision of settling tank before the water intake in the pond also reduces the risk of infection.

37 Metazoan diseases: Monogenetic Trematode infection CAUSATIVE AGENT Gyrodactylus sp. anddactylogyrus sp. COMMON SYMPTOMS Heavily infected fish show increased production of mucous, frayed fins, skin ulcers and damaged gills, Microscopic observation of the skin temporary mount of a portion of gill show the presence of the parasites. TREATMENT MEASURES Bath in ppm of formalin ranging from 1 to 3 hours, is very effective, Dip in 2 5% salt solution till the first sign of distress is equally beneficial. Bath or pond treatment with some soft organophosphorus insecticide (Malathion 0.25 ppm in pond) lesion/smear is also equally effective.

38 Metazoan diseases: Black spot disease CAUSATIVE AGENT Diplostomum sp. COMMON SYMPTOMS Development of small black or brown spots on several parts of the body and fins. Microscopic examination and dissection helps in locating rolled up and slowly moving worms embedded in the connective tissues. TREATMENT MEASURES Fish exhibiting black spots may be given an hour bath in 10 ppm picric acid solution. Removal of aquatic snails and preventing the entry of birds are some of the preventive measures. Infection does not spread from fish to fish and hence it is not worth treating infected stock.

39 Metazoan diseases: Argulosis CAUSATIVE AGENT Argulus sp. COMMON SYMPTOMS Development of haemorrhagic patches over the body and presence of the parasite in large number in and around the lesion. TREATMENT MEASURES Benzene hexachloride application in ppm with a second subsequent treatment after a week. Affected fish should also be given dip in ppm potassium permanganate solution which helps in avoiding secondary infection as well as accelerate the healing process ppm in pond also effectively controls the infection. Malathion also requires a second treatment after a week interval.

40 Metazoan diseases: Lernaeasis CAUSATIVE AGENT Lernaea sp. COMMON SYMPTOMS Anaemia, severe ulcerations and presence of attached cylindrical parasite of 1 to 2 cm length hanging outside. Sometimes causes mass mortality in carp nursery and rearing ponds. TREATMENT MEASURES Baths in concentrated solution of salt and potassium permanganate is reported to be effective. However, the author has found very little improvement by potassium permanganate treatment. Juveniles are embedded in the skin and hence remain unaffected. Bromex completely cures the infection when ppm.

41 Metazoan diseases: Leech infection CAUSATIVE AGENT Piscicola sp. COMMON SYMPTOMS They are not very dangerous. They affect the fish by their attachment and feeding. Area of attachment normally exhibit excessive mucus production, and some signs of haemorrhages. Open wounds are often infected by bacteria and fungi, Attacked fish show attached parasite, irritation and restlessness. TREATMENT MEASURES Removal of aquatic vegetation and maintenance of pond hygiene is the most important preventive measure. Hard objects such as stones, logs etc. should also be removed. Disinfection of pond with unslaked kg/ha should be done prior to next rearing operation, Short bath in 3 5% salt solution is very effective treatment.
