Effective management avoids gas bubble trauma
When aquaculture pond water suddenly warms, gas bubbles can form in the blood of aquatic animals and lead to stress or mortality.
Early Mortality Syndrome threatens Asia’s shrimp farms
The emerging disease Early Mortality Syndrome has caused large losses among shrimp farmers. EMS is characterized by mass mortalities during the first 30 days of culture.
Peru project studies blood cockles for stock enhancement, aquaculture
In Peru, some wild cockle communities have been so overfished that total fishing bans are being considered. A project was therefore established to develop sustainable spat production as a crucial step toward the implementation of a conservation strategy for blood cockles that fosters social aquaculture and stock enhancement. The project rested on the establishment of protocols for reproduction, larval culture and seeding; development of diagnostic tools for molluscan pathogens and the study of blood cockles’ genetic diversity.
Pike perch in recirculation aquaculture
Although pike perch aquaculture is growing, it still relies on wild breeders, whose spawning is induced by hormone treatment or manipulation of photoperiod and rearing temperature.
Blue-green algae pose toxic risks in shrimp, fish culture
The toxins from blue-green algae pose a threat to animal health and potentially to consumers if they are present in farmed product. Culture animals that ingest these toxins may not die, but can be weakened, increasing their susceptibility to pathogens.
Temperature affects shrimp survival, feed conversion
In laboratory tests with white shrimp, feed consumption was 36.5 percent higher at 33 degrees-C than at 29. Growth was similar at both temperatures.
Shrimp postlarvae: Know your starting point
Shrimp aquaculture could improve its position through more accurate and consistent identification and counting of postlarvae.
The Shrimp Book: Intensive production of shrimp
With relatively low use of land and water, intensive aquaculture systems can support much higher production than extensive systems.
Computer modeling helps grow fish
For farmers, computer modeling helps analyze crop production and environmental effects. For managers, it assists with carrying capacity assessments and licensing issues.
Experimental culture of wreckfish in Spain
Fast growth and attractive market prices make wreckfish an interesting option among the new species considered for commercial aquaculture.
Pacific oyster selective breeding in Australia
A partnership between CSIRO and the Australian seafood industry has significantly improved the selective breeding of Australian Pacific oysters.
Protecting fish in shark-infested waters
Sharks are predators to warmwater aquaculture that are not stopped by traditional cage nets when they seek the fish contained inside.
The Shrimp Book: Principal shrimp infectious diseases, diagnosis and management
Disease outbreaks in shrimp occur not only due to the presence of pathogens, but also to suboptimal culture conditions and system management.
Temperature affects feeding behavior of Pacific white shrimp
The authors evaluated the feed passage through the intestines of white shrimp under laboratory conditions. Feed consumption on feed trays was tested four times daily at different temperatures at an intensive culture farm.
Alaska’s purple-hinge rock scallops considered for aquaculture development
Purple-hinge rock scallops are highly prized by local communities and harvested for subsistence in coastal Alaska. To evaluate the suitability of purple-hinge rock scallops for mariculture in Alaska, the authors conducted a four-year grow-out study.
Aquaculture could enhance Mediterranean Sea urchin fishery
Although researchers in several countries are working to enhance sea urchin fisheries or commercial production, the development of a major commercial industry has been restrained by the lack of cost-effective production technology.
