Abstract/ Executive Summary:

The study was carried out to assess the impact of diseases on fish production in baors of Jessore district, Bangladesh from March 2012 to January 2013. Studied baors were selected randomly from each sub-district which covered 39.22% of total baors and 71.87% baor areas in Jessore district. All the surveyed baors were affected more or less by various diseases and in 80% baors noticeable production loss occurred almost every year. The main diseases were epizootic ulcerative syndrome (EUS), dropsy, gill rot and fin rot; out breaking time ranged from November to February each year. EUS was recorded in 85% baors whereas other diseases were found in various baors at various percentages: dropsy (75%), gill rot (45%) and fin rot (55%). Conferring to the number of affected fishes, 31.25% were affected by EUS, 37.5% by dropsy, 12.5% by gill rot and 18.75% by fin rot. In the year 2012, 0.513% loss of production has occurred that designated 0.7599 million BDT. Through successful work on disease control and management, production loss may be minimized.

Keywords: Impact, Fish diseases, Production, Baor, Oxbow lake

Location: Various baors of Jessore district, situated in the southwest part of Bangladesh

Start Date: 00-03-2012

End Date: 00-01-2013

Program Area: Pest Management

Commodity: Fish

Objectives:

The present study, impact of fish diseases on fish production of baors in Jessore district was investigated.

Methodology:

Study area and duration: The study was conducted in various baors of Jessore district, situated in the southwest part of Bangladesh. The total area of sample baors is 1352.63 ha which covers 71.87% of total area of baors in Jessore and the duration of the study was March 2012 to January 2013. Sampling framework: Sample baors were selected randomly ensuring the inclusion of each Upazila (subdistrict, 7 in number). Bangladesh has 5,488 ha baor area and in Jessore district the total area of baors is 1,882 hectors and thus the Jessore district contains 34.29% baor area of Bangladesh. Twenty baors were selected and primary data were collected employing effective techniques such as personal interview (home visit), focus group discussion (FGD), and telephonic interview. All the studied baors were managed under community based fisheries management approach. A total of 144 farmers and concerned members were interviewed for primary data collection. Fish production, investment and income data were collected from the respondents during interview. Common fishes of those baors were Labeo rohita, Catla catla, Cirrhina mrigala, L. calbasu, Hypophthalmichthys molitrix, Ctenopharyngodon idella, Cyprinus carpio, Puntius spp., Colisa fasciatus, Channa punctata, C. striatus, Salmostorma bacaila, Amblypharyngodon mola, Mystus tengra, Notopterus notopterus, Heteropneustes fossilis, Clarias batrachus, Glossogobius giuris, Wallago attu and Chanda ranga. The main diseases were EUS, dropsy, gill rot and fin rot which were identified in relation to identifying keys . Secondary data were collected from various government and fisheries correlated institutions and also collected from websites and published literatures.

Achievement/Findings:

Among the studied baors, the fish production and income are increased with the increasing cost and/or investment except some exceptions; some losses were occurred between 2007 and 2012.Four diseases were responsible for the loss of 0.513% of total fish production in the year of 2012. In 50% disease affected baors lime was used which was not sufficient to control the diseases.
