Sound travels very efficiently underwater, so the potential area impacted can be thousands of square kilometers or more. Anthropogenic activities such as commercial shipping, recreational activities, drilling, seismic exploration or energy production (hydroelectric power plants), have made underwater noise pollution an increasing and perhaps dominant factor in the aquatic environment. Nowadays,...

According to the UN Food and Agriculture Organization (FAO), “aquaculture, probably the fastest growing food-producing sector, now accounts for nearly 50 percent of the world's food fish” [1]. However, production is hampered by unpredictable mortalities that may be due to the negative interactions between fish and pathogenic bacteria. Intensive fish farming has resulted in a problematic growth ...

The diversity of fish consumed in Bangladesh is a key aspect of diet and culture. Although total fish production in Bangladesh has been rising due to aquaculture, there are widespread concerns for loss and overexploitation of floodplain capture fisheries. The two are not effectively the same, because the resulting diversity of fish differs under each circumstance, as does access to fish and res...

The demand for fish for food, recreation, and ornamental aquariums is steadily increasing. Natural fish populations have declined during the last several decades because of environmental degradation and over-fishing. This has resulted in an increased effort in the development of techniques for hatchery production of fish. Traditional aquaculture species such as trout, catfish, common carp, gold...

Monthly samples of six fish farms from January 2010 to December 2010 in the northern Iran, Haraz River, were used to determine relationship between chemical parameters of main water, inlet and outlet and their effects on fish growth and production. Results revealed that concentration of nutrients in outlet was more than that of inlet of farms and statistical analysis showed that there were sig...

1.0 INTRODUCTION The increasing of human population has increased the need for food supply. This with the need for quality fish protein has increased the demand for fish and fish products. The global consumption of fish and derived fish products has generally increased during recent decades (Wim et al., 2007). The cage aquaculture sector has grown very rapidly during the past 20 years and is pr...

Since the 1970s, global demand for fish has kept increasing, particularly in developing countries where population and income growth constitute the main drivers of the rise in world fish consumption. Although output from capture fisheries stagnates, total production of fish continues to rise, thanks to aquaculture. In 2010, aquaculture contributed up to 47% of world food fish production against...
