“…Almost all farmers reported that low price of fish was the main problems of fish farming. Similar types of pond farming constraints were found by some authors (Jahan et al 2015;Shamsuzzaman et al 2017;Das et al 2018). In conclusion, high value fishes are promising aquaculture species in Bangladesh.…”

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.

“…Evidence shows that 73% of rural households are engaged in some form of aquaculture across the country (Mazid 1999); 1.2 million people are directly employed, and 12 million more are indirectly engaged in fishery-related activities (Dey et al 2008). Das et al (2018) found that over 71% of total sampled farmed fish producers had either a primary or secondary education level. Their study also showed that farmers' education level affected the utilization of ponds and fish production (Khan 1986).…”

“…These included lack of technical knowledge; joint ownership of ponds; costly fish feed and other necessary inputs; inadequate knowledge about economics; insufficient quality of fingerlings; and limited access to credit options (Ahmed and Rab 1992;Gupta, Ahmed, and Bimbao 1992;Gupta et al 1999;Ahmed and Rab 1994;Gupta and Rab 1994;Lewis 1997;Chowdhury and Maharjan 2001;Thompson, Sultana, and Nuruzzaman Md 2005;ADB 2005). In a recent study, Das et al (2018) found that 80% of farmers do not receive any scientific aquaculture training, learning about fish farming from their ancestors or neighbors in an unscientific way. Another problem of Bangladesh's aquaculture is that even though pond size and depth affect the efficiency of fish production positively (Khan 1986), most aquaculture ponds in Bangladesh are small (e.g., 1-4 Decimal), with only 17.27% of ponds relatively large.…”

Aquaculture products are presently becoming a crucial part of consumers' diets. However, asymmetric information regarding farmed fish exposes consumers to ambiguity and often makes them confused. Therefore, this study aims to ascertain the levels of ambiguity tolerance (AT) and confusion avoidance (CA) related to farmed fish and to test if consumers' AT and CA influence their purchase intent (PI) of such fish. The impact of demographics on consumers' CA and AT is also explored. The data were obtained through a survey conducted on a randomly selected sample of 1053 households who either purchase and have purchased fish. The collected data were analyzed employing explorative factor analysis, structural equation modeling, and a simple regression model. The study demonstrates that AT had a positive and significant impact on the PI of farmed fish, and also reduced CA. However, the current high level of CA does not influence the PI of farmed fish.

“…Hence, the meat of broiler chickens, egg, and milk may contain antimicrobial residues which increase the possibility of developing resistant bacteria ( Hasan et al, 2012 ; Hassan et al, 2014 ) which represents a serious threat to public health ( Sachi et al, 2019 ). Aquaculture such as commercial fish and prawn farming is popular in Bangladesh as a source of low-cost protein to underprivileged groups of the society ( Ahmed et al, 2008 ; Das et al, 2018 ). Antimicrobial agents are also used as feed additives in fish farming triggering antimicrobial resistant bacteria in water bodies and contaminating the aquaculture and the environment ( Ahaduzzaman et al, 2014 ; Hassan et al, 2015 ).…”

Background The agricultural food products industry in Bangladesh depends on utilizing antimicrobials indiscriminately as growth promoters and for controlling infectious diseases. Thus, there is always a risk of antimicrobial agent accumulation in food sources that originate from agricultural production. Methods In the present study, we collected data from published articles between January, 2013 and December, 2019 on antimicrobial residues in human food sources such as meat, milk, eggs, and fishes. Results Liver contained the highest percentage of antimicrobial residues (74%; 95% CI: 59.66–85.37) against the in vitro enteric pathogen Escherichia coli in layer chickens. Similar results were demonstrated in liver (68%; 95% CI: 53.30–80.48) and kidney (66%, 95% CI: 51.23–78.79) of layer chickens against Bacillus cereus and Bacillus subtilis . Amongst all antibiotics, the highest concentrations of ciprofloxacin were detected in kidney (48.57%; 95% CI: 31.38–66.01), followed by liver (47.56; 95% CI: 40.88–54.30) of broiler chickens. Ciprofloxacin was also present in liver (46.15%; 95% CI: 33.70–58.96) of layer chickens. The percentage of ciprofloxacin in thigh and breast meat in broiler bird were 41.54% (95% CI: 34.54–48.79) and 37.95% (95% CI: 31.11–45.15) respectively. Enrofloxacin was the second most dominant antimicrobial agent and was present in the liver of both types of poultry (Broiler and Layer chickens: 41.54%; 95% CI: 29.44–54.4 and 437.33%; 95% CI: 30.99–44.01). The prevalence rates of enrofloxacin in thigh and breast meat of broiler chickens were 24.10% (95% CI: 18.28–30.73) and 20.51% (95% CI: 15.08–26.87), respectively. Tetracycline, a commonly used antibiotic in livestock, was present in the liver (49.23%; 95% CI: 36.60–61.93) of layer chickens. In case of aquaculture food products, the highest amount of amoxicillin (683.2 mg/kg) was detected in Tilapia fish ( Oreochromis niloticus ), followed by 584.4 mg/kg in climbing perch ( Anabas testudineus ) and 555.6 mg/kg in Rui fish ( Labeo rohita ). Among the five types of fishes, Rui fish (0.000515 mg/kg) contained the highest concentrations of chloramphenicol antibiotic residues. Conclusions The presence of antimicrobial residues in meat, milk, egg, and fish is a serious public health threat due to the potential induction of antimicrobial resistance. It can negatively impact the food supply chain, especially with the current strain that it is already facing with the current COVID-19 pandemic. The findings of the present study highlight the ongoing risk of residual antimicrobial agents in food of animal origin in Bangladesh and countries with similar practices. This can draw the attention of public health officials to propose plans to mitigate or stop th...
