La carrera de investigador del veterano de 50 años ha sido verdaderamente extraordinaria.
What to do with empty big box stores? Turn them into fish farms
The Innovative Aquaculture Alliance aims to install fish farms in empty big-box retail stores and other abandoned real estate across the United States.
Defining ranges for water quality variables presents complex, challenging process
The creation and application of reference tables for acceptable concentration ranges of physical and chemical water quality variables for culture organisms would be challenging due to the differing tolerances found among the many farmed species.
¿Qué hacer con las hiper- tiendas desocupadas? Convertirlas en granjas de peces
Innovative Aquaculture Alliance tiene como objetivo instalar granjas piscícolas en hiper-tiendas minoristas vacías y otros bienes inmuebles abandonados a lo largo de los Estados Unidos.
At Aquaculture America 2018, signs of support for thriving domestic industry
Aquaculture must reshape its public narrative in order for the blue revolution to transpire. That’s what many prominent voices were saying at the World Aquaculture Society’s annual U.S. conference in Las Vegas.
Ich parasite serves as vector to transmit bacteria to fish
The authors used Ichthyophthirius multifiliis (ich) and fluorescent-tagged Edwardsiella ictaluri to examine whether parasites vector bacteria into fish.
Parasitism enhances susceptibility to bacterial infection in tilapia
The authors conducted a study to evaluate whether tilapia infected with Gyrodactylus were more susceptible to Streptococcus iniae. The research found that fish with a solo infection of Gyrodactylus or Streptococcus had less than 7 percent total mortality.
Common off-flavors in channel catfish following partial pond harvest
The authors conducted a study to determine whether channel catfish systematically develop off-flavors after partial harvest as well as the possible origins of the flavors.
High-density split-pond systems offer high output, low maintenance
The split-pond culture system offers several advantages over traditional fish ponds. Aerating the small fish-confinement area is more effective at maintaining adequate levels of dissolved oxygen than in traditional ponds.
Antigens provide immunity against ich in channel catfish trials
Vaccination against the Ich parasite is an alternative to chemical treatment. Fish develop a humoral immune response to trophont antigens, with the degree of protection related to the immunizing doses of trophonts used.
With animal welfare an emerging consumer concern, fish farmers take stock
Food producers are educating themselves on the latest in animal health and welfare and humane harvesting and processing practices. A recent webinar highlighted issues specific to aquatic animals.
Bath immersion, booster vaccination strategy holds potential for protecting juvenile tilapia
In a study, vaccination of juvenile tilapia by bath immersion followed by two booster vaccinations stimulated specific antibody responses and protection against S. iniae challenge.
Misuses of sodium bicarbonate in pond aquaculture
Sodium bicarbonate is a useful chemical in recirculating aquaculture systems and fish transport tanks. However, two common uses of the compound in pond culture – to remove carbon dioxide and treat off-flavors – do not work.
Tilapia vaccines: important disease prevention, biosecurity tools
Tilapia vaccines can protect the fish against infectious diseases by providing pathogen-specific acquired immunity that prevents recurring infections.
Canada invests in ‘clean-tech’ aquaculture
A handful of aquaculture companies in British Columbia are upgrading to "clean-tech" equipment to make their businesses more sustainable and efficient.
Low-salinity fish production technology can cut costs, aid biosecurity
Virginia Tech Aquaculture Research Group collaborated with MariCal to examine commercial feasibility of raising cobia in RAS under low-salinity conditions.
Managing pre-harvest off-flavors in pond-raised catfish
Although causes of pre-harvest off-flavors in catfish differ due to climate, water quality and pond hydrology, blue-green algae is a common culprit.
