An evaluation of fish health-management practices and occupational health hazards associated with Pangasius catfish (Pangasianodon hypophthalmus
) aquaculture in the Mekong Delta, Vietnam

The present study was conducted to know the culture strategies and fish health and disease problems in pond aquaculture in Mymensingh, Bogra and Pabna districts of Bangladesh. Questionnaire interview and participatory rural appraisal tools like focus group discussion (FGD) were conducted with selected fish farmers. In total 90 farmers were interviewed and 9 FGD sessions were conducted. Most of the respondents practiced carp and pangas polyculture and they had disease problems in their ponds. Prevalence of fish disease varied with cultured species and locations. The most prevalent diseases as reported by the farmers were pop eye (57.78%), ventral reddening (55.55%), tail and fin rot (48.89), hemorrhagic lesion over the body surface (45.56%), dropsy (40%), gill rot (40%), white spot (40%) and epizootic ulcerative syndrome or EUS (33.33%). According to farmers opinion most susceptible species to disease was silver carp, Hypophthalmichthys molitrix (57.78%); followed by mrigal, Cirrhinus cirrhosus (50%); catla, Catla catla (47.78%); sarputi, Barbodes gonionotus (47.78%); rui, Labio rohita (42.22%) and pangas, Pangasianodon hypophthalmus (42.22%). Higher mortality was found in pangas (53.56%). Clinically, pangas, koi and sarputi were found severely affected. Most of the farmers used some treatment measures against disease problems. This study also highlited some fish health management problems in pond aquaculture. Further studies should include identification and characterization of pathogens involved in different types of diseases in pond aquaculture. DOI: http://dx.doi.org/10.3329/jbau.v11i2.19944 J.

Structured Questionnaire

This study was performed to understand the constraints of health management of commerciallycultured high value fishes including gulsha (Mystus cavasius), shing (Heteropneustes fossilis) and koi (Anabastestudineus). One hundred farmers were interviewed through structured questionnaire in Mymensingh andJashore districts. Most of the farmers practiced polyculture of gulsha and shing with carps and monocultureof koi high densities. All the three species suffered from a number of serious diseases under farmingconditions. Most prevalent clinical signs of diseases were ulcerative hemorrhagic lesion, whitishappearance over body surface, ventral and mouth reddening and fin rot. The most susceptiblespecies to disease was shing with a higher average mortality of 43.33% followed by gulsha(36.71%) and koi (38.76%). Diagnosis of disease was the single most important constraints ofhealth management followed by lack of farmer’s knowledge on fish health and diseases, presence ofhuge number of poor quality medicine, ineffectiveness and indiscriminate use of such medicine,lack of farmer’s ability on application of medicine and absence of qualified fish health adviser.Lack of good quality fish seed, feed and water were identified as the main resource problemsassociated with fish health management. The study also identified a number of general constraintsof farming of high value fish which included low price of fish, higher feed cost, and outbreak ofdiseases, high land tax, electricity bill and marketing problem. Further studies should focus on thedevelopment of strategies for better health management practices for sustainable commercial cultureof high value fishes.

SummaryIn this article an on-farm monitoring approach on udder health is presented. Monitoring of udder health consists of regular collection and analysis of data and of the regular evaluation of management practices. The ultimate goal is to manage critical control points in udder health management, such as hygiene, body condition, teat ends and treatments, in such a way that results (udder health parameters) are always optimal. Mastitis, however, is a multifactorial disease, and in real life it is not possible to fully prevent all mastitis problems. Therefore udder health data are also monitored with the goal to pick up deviations before they lead to (clinical) problems. By quantifying udder health data and management, a farm is approached as a business, with much attention for efficiency, thought over processes, clear agreements and goals, and including evaluation of processes and results. The whole approach starts with setting SMART (Specific, Measurable, Acceptable, Realistic, Time-bound) goals, followed by an action plan to realize these goals.
