Phenotypic and genetic diversity of motile aeromonads isolated from diseased fish and fish farms
Samples from the kidney of 100 diseased fish with signs of haemorrhagic septicemia and 50 samples from outlet water of fish farms were taken aseptically and cultured. In the laboratory, 75 colonies of gram-negative bacteria were biochemically diagnosed as motile aeromonads in our Bacteriology Laboratory Unit using API 20E rapid identification system. The genotype identification using specific p...
متن کاملSimulator Software for Marine Fish Farms Sustainability

This paper discusses many issues given when fish, mussels, oysters or other shellfish are fed and their relation with the sustainability. There are several simulator software for fish growth and there are several published models for sustainability, but, as far as we know, there are very few simulator software for marine fish ...
متن کاملFish farms, parasites, and predators: implications for salmon population dynamics.
For some salmon populations, the individual and population effects of sea lice (Lepeophtheirus salmonis) transmission from sea cage salmon farms is probably mediated by predation, which is a primary natural source of mortality of juvenile salmon. We examined how sea lice infestation affects predation risk and mortality of juvenile pink (Oncorhynchus gorbuscha) and chum (O. keta) salmon, and dev...
متن کاملAntibacterial Drugs in Fish Farms: Application and Its Effects
Antibacterial chemotherapy has been applied in aquaculture for over 60 years. The discovery of antibacterials changed the treatment of infectious diseases, leading to a dramatic reduction in morbidity and mortality, and contributing to significant advances in the health of the general population. Antibacterials are used both prophylactically, at times of heightened risk of disease and therapeut...
متن کاملManagement Challenges and Product Quality of Fish Farms in Greece
The purpose of the present work is to review some data for the management challenges that the aquaculture industry in Greece is currently facing. The results indicate that Greek aquaculture fish farms apply Human Resources Management (HRM) practices which can increase motivation, commitment and job satisfaction of their personnel. In turn, these practices can increase the productivity of the bu...
