“…The acquisition of antibiotic resistance in potentially pathogenic bacteria such as Vibrio sp. is a typical side effect of antibiotic overuse (Le et al, 2005;Nakayama et al, 2006). Further, the use of the antibiotics oxyteracycline and oxolinic acid has been shown to decrease the expression of immune-related genes associated with antibacterial processes in shrimp (Fagutao et al, 2009).…”

Zero exchange super-intensive recirculating aquaculture systems (RAS) represent an environmentally "friendly" alternative to traditional shrimp culture methods, however the susceptibility to pathogens typically increases as the density of cultured organisms increases. The study describes a greenhouse-enclosed super-intensive RAS, utilizing culture water from a 62-day nursery trial, to grow juvenile (0.99 g) Litopenaeus vannamei, Pacific White Shrimp, to market-size under high stocking density (450/m 3 ). The study evaluated the effects of foam fractionation and settling tank particulate control methods on water quality and microbial particulate related flora in four 40 m 3 tanks with two replicates per control method under no water exchange. Microbial communities were distinguished at the gram-stain level using flow cytometric fluorescent activated cell sorter (FACS) methods. Differentiation between all other populations of organisms and particles between 1~20 μm was based upon autofluorescence and forward scatter (a size indicative light parameter) using FACS. Analysis of variance indicated that the microbial communities associated with each particulate control method did not deviate from one another significantly (p>0.05). Gram-positive bacteria were the dominate fraction regardless of particulate control method (p<0.05). Six unique autofluorescence signals were consistently present within each RAS. This study is a first step in using flow cytometry as a tool to document changes in microbial communities in no water exchange super-intensive system for production of marketable shrimp. Shrimp yield and survival was high: 9.34~9.75 kg/m 3 and 94.5%~96.9%, respectively. Further, the data suggest that the use of pre-conditioned water may help to prevent ammonia and nitrite overload and decrease pathogenic organism prevalence.

“…Aquaculture industry represents a significant share of the antimicrobial consumption in animal production. Extremely high rates of antimicrobial consumption have been recorded in aquaculture farming in middle and lowincome countries 43,44 . It is believed that growth in aquaculture production systems will increase the antimicrobial consumption and contamination of the aquatic environments with antimicrobial residues in future 45 .…”

Antimicrobial resistance (AMR) is a worldwide 'OneHealth' problem. The spread of AMR has limited the treatment options against infectious diseases. Inappropriate use of antimicrobials, is a major contributor for the development of AMR and its spread. In animal husbandry, antimicrobials are used for treating infectious diseases and in sub-therapeutic concentrations for growth promotion and disease prophylaxis. The use of antimicrobials in sub-therapeutic concentrations exerts selective pressure on bacteria and results in the emergence of bacterial strains resistant to one or more antimicrobials. The food animals raised on sub-optimal doses of antibiotics become reservoirs of resistant bacterial strains, transmitted subsequently to man and the environment. Various human, animal and environmental health agencies have decided to jointly address this problem. Establishment of integrated and harmonized AMR surveillance programmes, reduced use of antimicrobials in animal production, good governance of veterinary services, and development of new antimicrobials and their alternatives are some of the AMR management strategies in animals. Antibiotics are indispensable for human health; however, they should be totally banned in the food animals to preserve effectiveness of these drugs. In India, use of antimicrobials in food animals is limited for disease prophylaxis and growth promotion. However, absence of uniform regulations on the use of antimicrobials in animal production threatens the rationale use of these drugs in livestock.
