BANGLADESH FISHERIES RESEARCH INSTITUTE 1. Introduction The fish and fisheries are integral part of the culture and heritage of Bangladesh. The sector is quite significant in the country as it offers an important source of earning livelihood, foreign exchange and food supply. Keeping in view the immense potentials of fisheries sector in providing better nutrition and job opportunities, particularly to the poorest of the poor, and the urgency for optimum scientific utilization of the aquatic heritage, the President of the people`s Republic of Bangladesh was pleased to promulgate an Ordinance entitled “The Fisheries Research Institute Ordinance, 1984” on the 11 day of July 1984. In pursuance of this Ordinance the Institute was established in July 1984. In 1997 the Institute was renamed as Bangladesh Fisheries Research Institute (BFRI). Through the institute was established in 1984, it actually started functioning in 1986 with the recruitment of required manpower and creation of initial research facilities. Since then, the institute has been playing a key role in assisting the nation to achieve the goal of fisheries development as set out in successive development plans. The institute is an autonomous research organization and linked up administratively with the Ministry of Fisheries and Livestock. The general direction, administration and supervision of the affairs of the institute is vested in the Board of Governors. The headquarters of the institute is located in Mymensingh. The institute has 5 stations and 5 sub-stations based on different aquatic ecosystems. The overall research, training and management activities of the Institute are carried out in close cooperation and linkages with various national and international organizations/agencies. The international organizations are: WB/IDA, IDRC, FAO, UNDP, USAID, NACA, IFAD, ICLARM(World Fish), ACIAR, DFID, NORAD etc. The institute pays much importance to strengthening its capabilities of its scientists, administrative and management personnel through in-country and overseas long and short-term training, study tour etc. mainly overseas through WB/IDA, BTA, MONBUSHO, USAID, FAO/UNDP, IDRC etc. To transfer the technologies and management practices developed through research, the Bangladesh Fisheries Research Institute organizes regularly specific training programs to extension workers, farmers and others namely Improved fish culture management, Brood fish and hatchery management for seed production, Carp poly culture, Culture system for tilapia and cat fishes, Farming system research methodologies, Backyard shrimp hatchery, Fisheries and environment, Fish disease diagnosis and health management, Fish genetics resources, Shrimp culture and management etc. 2. Vision The vision of BFRI is to become a Center of Excellence on Fisheries Research to evolve aquaculture technologies, and management guidelines for open water fisheries to optimize sustainable harvest from national aquatic resources in consonance with environment, economics and equity and to assist the country in all matters relating to its fisheries R&D.

5. Research progress during last five years
a. Establishment of new Shrimp Research Station in Bagerhat
Enhancing shrimp production, shrimp health management, shrimp feed and nutrition, post-harvest
handling and quality control of shrimp and shrimp products the new shrimp research station establish at
sadarupazila under Bagerhat District with an area of 8.0 ha. The station consists of 2 storied office-cum
laboratory building, 3 storied staff dormitory and 4 storied training dormitory with 9 pond complex and
one shrimp hatchery. March, 2011 Honorable PrimeMinister inaugurated this station.
b. Hilsafisheries management through conservation of jatka
Riverine Station of Bangladesh Fisheries Research Institute, Chandpur has been working on the hilsa
fisheries since 1986 and continuously recommending various measures to the Govt. specially identify
5jatka/hilsasanctuary for its increase sustainable harvest and conservation-management.
Based on the research result on diversity and abundance of jatka (juveniles of hilsa) availability in the
successive three years with its required water quality in the Hilzla-Mehendigonj of Barisal district where
confluences of three rivers (branches of Meghna river like Nayabhangani, Lata and Dharmogonj) and
area covered as 60 square kilometer (Nasakathis, Harinathpur and dhulkhola point of Hizlaupazilla and
Bhasanchar point of Mehendigonjupazilla) are proposed to declare as jatka/hilsa sanctuary which would
be treated as sixth jatka/hilsa sanctuary (Table 1 and Map 1) of the country. The proposed ban period is
March-April. If we establish sixth jatka/hilsa sanctuary it will play a big role in hilsa production like
other 5 hilsa sanctuaries in the country.

c. Pearl culture
BFRI successfully developed pearl culture technique in pond from fresh water mussel. Maximum 100
mg (average 50mg) weight of pearl was produced in 8 months.The image pearl is successfully
produced within 6 months. Rice pearl produced in Bangovabon&Netrokona’s ponds. Three shapes such
as round, rice and irregular were obtained. Another achievement that maximum 5 mm, average 2-3 mm
pearl was obtained within 5 months. Four colours of pearl such as pink, white, ash and orange are
produced successfully. Dissemination of technology is going on through farmer’s day, training &
demonstration farm. About 300 female fish farmers were trained up about modern technique of pearl
culture in pond.
d. Conserve of gene pool and develop breeding technology of threatened fish species IUCN, Bangladesh has documented about 56 freshwater fish species have become critically or somewhat endangered. For conservation of gene pool and stock improvement of endangered fish species, development of induced breeding technology is of prior importance through which mass seed production could be ensured. Freshwater station of BFRI has developed artificial breeding and culture techniques on some of these threatened fishes (such as mahseer, gonia, bata, kalbaush, bhagna, pabda, gulsha, koi etc) with the aim of ensuring their conservation and rehabilitation. To conserve fish species in freshwater recently BFRI release 5000 fry of mahseer in Sumeswaryriver in Netrokona District. e. Stock improvement of GIFT strain through further selection in Bangladesh Tilapia is the leading species in Bangladesh aquaculture as the species is well adapted to Bangladesh condition, easy to propagate, grows fast, converts the artificial food very efficiently and tolerate the changes in water quality as well as disease compared to other cultured species. In last decades over 300 tilapia hatcheries have been established and producing about 4.0 billion fry. But most of the hatcheries are using inferior quality brood for the production of tilapia fry. There is a great demand of quality of tilapia seeds in the country. It is presumed that tilapia farming will largely be expanded both in small and commercial scales, so there will be an extreme need for huge number of quality seeds. To overcome this situation, Bangladesh Fisheries Research Institute has undertaken research work on genetic up gradation of GIFT through family selection protocol. This research results revealed that F-7 generation of GIFT strain has 43% higher harvest weight than that of the founder population.
f. Genetically improvedrohuLabeorohitastockdeveloped. Rohu, Labeorohita, is the most popular species among endemic carps for aquaculture. Rohu contributes more than 22% of total aquaculture production of the country while around 24% of total fish production comes from all the four Indian major carps. Genetic stock improvement for the establishment of a brood bank with outbred selected population of rohu, Labeorohita, was attempted in 2000.Two wild caught populations from Brahmaputra and Jamuna and one domesticated stock of the Freshwater Station of Bangladesh Fisheries Research Institute (FS-BFRI), Mymensingh, were used in a diallellic mating design. The Family selection has been initiated with the F 1 rohu stock in 2008-09. Sixty progeny families of F 2 were produced through a nested mating design between selected pair of female and male (2:1) i.e., milt from a common male separately fertilized eggs of two females and produced a pair of half sib family. Out of 80 breeding trials, the sixty progeny families of F 3 rohu stock has been already produced through pair mating using best selected female and male individuals (1:1) of F 2 communal broods. The experiment will be performed to find out variations regarding growth among different families through PIT tagging and communal rearing for further selection. BFRI improved strain of F 2 rohu, through a field trial of experiment conducted for 6 months in 6 ponds are performed significantly (P

7. Current and Future Challenges
In the past decade a wide range of changes affecting fisheries have taken place, including very large
increases in fish production from all forms of aquaculture, declines in most capture fisheries, encroachment
and degradation of natural resources, rapid urbanization, infrastructure investments that have negatively
impacted fisheries, and increased pollution. Production from the eight million hectares of seasonal flood-
land is by far the mostimportant component of the inland fishery, which includes floodplains, beelsand
rivers. Asmonsoon water annually spreads across the floodplain, nutrients are released and
primaryproduction explodes over a very wide area. So long as adequate recruitment is present, therefollows
tremendous fisheries production.
Unlike the inland fishery there is more of a commercial focus to the coastal andmarine fishery. Access to
most coastal and marine waters entails the use of a boat and,except for river mouths and estuaries, motorized
boats are a requirement. The industrialtrawl fishery can exploit deeper water fishery resources up to a depth
of 50-200 m, and theprospects for exploiting the deepest waters have not been fully explored.
It is generally agreed that both freshwater and brackish-water aquaculture willcontinue to grow at about
5.6% and 3.2% per year respectively, which is slower than the 20%per annum reported in the past decade.
There is also a general consensus among mostauthorities that the capture fisheries, both inland and
coastal/marine, are in decline, at rates ofabout 2.1% and 1.6% per year, respectively. There is not unanimous
agreement with thisstatement, however, particularly regarding declines in the marine sector, and there is
someevidence that deep water offshore stocks do offer some opportunities for the industrialtrawler fleet.
Aquaculture specifically shrimp and prawn production which is also prime export earner, involves
manufacture of numerous inputs such as feed, fertilizers, pesticides and veterinary drugs, as well as of
technicaldevices for water treatment and pond operation. The off-farm post-harvestproduction links also
include processors and marketing agents (packaging,transport, export-importers, consumers, quality
control). In recent years ban on shrimp and prawn export make the sector more vulnerable.
Loss of biodiversity and some other important factors/problems hinders the growth of fisheries sub-sector.
The major causes of loss of biodiversity and the major problems of fisheries sub-sector are:
i. Aggradations of habitats due to siltation
ii. Habitat alteration and fragmentation
iii. Over and indiscriminate fishing
iv. Disturbance to pre-spawning migration due to FCD/I projects
v. Over exploitation of swamp forests
vi. Unplanned road, culvert and bridge construction
vii. Water pollution due to domestic and industrial wastes and effluent
viii. Unavailability of quality fish seed
ix. Increasing use of agricultural inputs
x. Inadequacy in fisheries management
xi. Reluctance in obeying fisheries laws and regulations as well as weak enforcement of such lawsxii. Climate change implications
xiii. Inadequate extension services
xiv. Short term lease / high lease value
Challenges
i. Preventing habitat degradation due to anthropogenic and natural factors
ii. Reducing impacts of climate changes
iii. Popularizing vertical expansion of aquaculture
iv. Dredging rivers, canals, haors, baors and floodplains
v. Providing financial support
vi. Providing technical and mechanical support
vii. Applying laws and regulations
viii. Maintaining and conserving fish sanctuaries
ix. Competition in the international markets
x. Stabilising price of fish feed and other inputs
xi. Creating channels for appropriate price of fish and fishery products
xii. Preventing water pollution
xiii. Preventing genetic pollution
xiv. Maintaining fish-food safetyand quality
xv. Exploitation of marine resources
xvi. Adapting appropriate policies for development and management of fisheries resources
xvii.Maintaining and conserving fish biodiversity
Of the major long-term environmental concerns, global climate change is the most serious issue likely to
affect Bangladesh over the coming decades. Although impacts of global warming are still far from precisely
predictable, the prospect is sufficiently probable and alarming to warrant precautionary action at both
national and international levels. Both coastal and freshwater fisheries are likely to be adversely affected by
changing temperature, siltation, inundation and salinity regimes.
Capture fishery issues
• Protect dry season water flows
• Restoration of habitat and fish species;
• Develop and implement fisheries management regulations
• Integrated Coastal Fisheries Resource Management
• Maintenance of ecosystem health andmanagement of pollution
• Coping with climate changes.
Aquaculture issues
• Stock improvement
• Conservation of genetic diversity
• Rationalization of farmed fish species• Shrimp (Bagda) and prawn (Golda) production and value chain addition
• Environmental carrying capacity
• Food safety, quality control and disease prevention
Emerging issues
While aquaculture has been progressing with reasonable success as a result of various technologies
developed and disseminated, some new and challenging issues have cropped up in the process, which need
to be seriously addressed to maintain the current growth of the aquaculture industry. Some of the important
issues are listed below:
• Brood stock management and quality seed production,
• Quality fish feeds and other farm inputs,
• Threatened aquatic bio-diversity,
• Infectious fish and shrimp diseases,
• Quality of aquaculture and fisheries products, value addition and trade issues,
• Pearl culture
• Riverine fishery dynamics,
• Livelihood changes of riverine and coastal fishermen,
• HACCP and traceability with respect to shrimp export.
Fisheries research need tobe upgraded to continue the flow of technology generation. Various policies of
other ministries impinge upon fisheries sub-sector development because these policies regulate the
availability of, access to and use pattern of the open water bodies. These need to be coordinated and a
necessary legal framework need to be formulated. Quality assurance in fish harvesting, processing,
marketing and exportneed to be especially emphasised.
Sub-sectoral Development Strategies and Policies
Following measures are required to be taken for further development of the aquaculture to harness its
production potential and to establish aquaculture as a profitable economic venture:
• Development of hatchery and nursery in private sector need to be encouraged to ensure availability
of adequate quantity of quality fish seed all over the country.
• Ponds lying fallow due to multiple ownership or other reasons should be brought under aquaculture
by promulgation and enforcement of laws.
• Integration of aquaculture with household farming and other rural development programmes based
on land and waters to increase overall productivity and income of the farming community.
• Adoption of best management practices (BMP) for enhancing aquaculture production.
• Establishment and strengthening of fish/shrimp disease diagnostic laboratories in the research
institutions for required assistance to farmers.
• Fisheries extension and training programmes need to be strengthened to properly train and advise
fish farmers.
Freshwater aquaculture research
• Development of breeding and culture technology of the endangered species and formulation of
guidelines for their conservation
• Development of low-cost eco-region specific aquaculture technology for resource poor farmers
• Quality fish feed development using conventional and non-conventional

Measures need to be undertaken for bringing improvement in inland open water fisheries:
• Fisheries need to be given due priority in the management and utilization of all open water bodies.
• Restoration of depleted fisheries by stocking of fingerlings in manageable water bodies, particularly
floodplains, and managing them through community approach.
• Allow natural fish recruitment through establishment of fish sanctuaries to enhance production of
open waters.
• Bring all manageable open water bodies under culture-based capture fisheries management approach
to increase production.
• Ensure alternate employment for fishermen to implement fishing ban during breeding season.
Inland open water fisheries research

• Improvement in the management technology for beels, haors and baors fishery
• Refinement of pen and cage culture
• Monitoring of carrying capacity of rivers
• Population dynamics and assessment of hilsa and other riverine fishes.
• Socio-economic impact and livelihood of fishers
Following measures should be undertaken for development of marine fisheries:
• Regular assessment of stock and proper monitoring of catch for effective regulation of the artisanal
and trawl fisheries for sustainable production.
• Development of techniques for exploitation of deep-sea fisheries.
• Assessment and utilization of shrimp by-catch and minimization of post-harvest loss by producing
value-added products.
