Abstract/ Executive Summary:

The present study was conducted to know the status of biosecurity and prevalent parasitic diseases in finfish hatcheries of Jessore district. The peak season of seed production was found April to May. Management of biosecurity has been practiced to prevent disease outbreaks and exert quite satisfactory. It was observed; hatchery owners cleaned their hatchery units regularly and maintained hygiene (76.66%), water quality (56.66%), disinfected equipments (76.00%), stocked disease free broods (76.00%) and quarantine (56.66%). Prevalence of diseases were- lernaeasis (34.10%), argulosis (23.86%), leeches (11.36%), dactylogyrosis (7.95%), gyrodactylosis (10.23%) and others (12.50%) in brood fish and fry. In broods, average prevalence was 16.67% with 9.25% mortality. Besides average prevalence was 10-15% with 10% mortality in fry. The epizootiological pattern showed the highest frequency of parasitic diseases during winter because of loss of appetites. The study demonstrated that sumithion was used by (93.32%), magic (46.33%), depterax (56.67%), lime with KMnO₄ (80.00%), lime with salt (66.67%) and lime- salt- KMnO₄ (50.00%) by hatchery owners respectively for treatments. Lack of assistance, proper knowledge and suitable therapeutics with its proper use were the major problems in the hatcheries.

Keywords: Finfish hatchery, Biosecurity, Parasitic diseases, Jessore

Location: At the Chanchra area of Jessore district, Bangladesh

Start Date: 00-03-2012

End Date: 00-01-2013

Program Area: Animal Health and Management

Commodity: Diseases

Objectives:

To avoid undesirable human interference in natural waters, and even to control some of the more harmful parasites.

Methodology:

Study area and duration: The study was carried out in the finfish hatcheries, located at the Chanchra area of Jessore district, Bangladesh. Study duration was one year, from March 2012 to January 2013. Data collection: Thirty out of eighty eight hatcheries were randomly selected during the study period for data collection. The data were collected on monthly basis through a structured questionnaire. After finalizing the questionnaire, direct interviewing of the hatchery owners or hatchery managers were carried out. In order to minimize errors, data were collected in local units. These were subsequently converted into appropriate units. Data analysis: Collected data were analyzed using Microsoft Excel 2007.

Achievement/Findings:

Production of quality seeds in a hatchery mostly depends on maintenance of proper quality of each unit present in a hatchery. Parasitic diseases in a hatchery have become an alarming factor which may be controlled by taking appropriate biosecurity measures. From the findings of this study it may be concluded that maximum hatchery owners of the study area face enormous problems during production cycle which may cause considerable losses of them. Considering this condition Government and Non- Government organizations should come forward and take indispensable steps to resolve these problems.
