■ Abstract With continued human pressure on marine fisheries and ocean resources, aquaculture has become one of the most promising avenues for increasing marine fish production in the future. This review presents recent trends and future prospects for the aquaculture industry, with particular attention paid to ocean farming and carnivorous finfish species. The benefits of farming carnivorous fi...
Polycyclic aromatic hydrocarbons (PAHs) and heavy metals contribute to pollutants in aquaculture facilities and thus need to be further investigated. Besides, there is little information regarding PAHs and heavy metals in the tissues of cultured fish, and the risks associated to consumption. In this review, emphasis has been made on the detection of PAHs and heavy metals in cultured fish specie...

Aquaculture is emerging as the fastest growing food-producing industry in the world because of the increasing demand for food fish consumption. However, the intensive culture of food fish has led to outbreaks of various bacterial diseases, resulting in annual economic losses to the aquaculture industry estimated at billions of dollars worldwide. Feeding infected fish with antibiotic-medicated f...
In saline water ponds in the tropics, a halocline may occur due to rainfall, especially rainy season. The critical impacts of haloclines are heat insulation and obstruction vertical mixing. Considering quality ponds, appearance could have an impact on its variation, as pond be impacted by both Especially with purpose aquaculture production, lead dangerous risks, such physiological stress produc...
An experimental culture of snubnose pompano, Trachinotus blochii was conducted for 210 days in low saline water to understand the growth potential small indigenous Re-circulatory Aquaculture Systems (iRAS) using cost fishmeal-based diet developed pompano. In present study, pompano has reached marketable size (287.32±4.84 g) during period with excellent feed conversion ratio 1.74±0.01 and averag...
With the rapid development of the fisheries, aquaculture species have degraded, especially for high-density aquaculture of random discharge of industrial wastewater and domestic sewage so that capacity of self-purification and regulation of ponds reduced, and water environment exacerbated. For instance, baits and feces entered into the water in the farming mode of main feeding, so that the amou...
Oysters with potential for aquaculture are found throughout the tropics and subtropics, but few species have been cultured and in only a few tropical countries. This monograph reviews the biology, ecology and culture techniques, both experimental and commercial, used in the tropics; describes the problems associated with tropical oyster farming; and points out research needs to develop further ...
Aquaculture production of molluscs is worth US$11 billion per year and represents 65% of World mollusc product. A significant limitation to the industry is loss of stock through bacterial disease. Traditional methods to combat disease with antibiotics have been questioned and alternatives have been sought. The field of probiotics as well as the screening methods used to acquire probiotic strain...
Efforts are on the way on the Swedish West Coast to develop the capacity for cultivation of marine resources, notably of kelps. Given that this is a region of great natural and national heritage, public opposition to marine developments has been identified as a possible risk factor. This survey thus sought to shed light on awareness levels, perceptions of different types of aquaculture and on r...
