Simulator Software for Marine Fish Farms Sustainability
One of the main costs of the marine fish farms is the extruded feed. 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 کاملPhenotypic 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 کاملA Simulator for Sustainability in Marine Fish Farms
One of the main costs of the marine farms is the extruded feed. This paper discusses many issues given when fish, mussels, oysters or other shellfish are fed. Several published systems for sustainability are also described. Authors will propose a simulator based on underwater wireless sensors that will solve issues aforementioned giving sustainability for marine farms. Because sensors are not w...
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 کاملProxy Measures of Fitness Suggest Coastal Fish Farms Can Act as Population Sources and Not Ecological Traps for Wild Gadoid Fish
BACKGROUND Ecological traps form when artificial structures are added to natural habitats and induce mismatches between habitat preferences and fitness consequences. Their existence in terrestrial systems has been documented, yet little evidence suggests they occur in marine environments. Coastal fish farms are widespread artificial structures in coastal ecosystems and are highly attractive to ...
