Hybrid assay can detect IMNV in resource-poor settings
The method can shorten analysis time and has applications for IMNV diagnosis in resource-poor settings because it does not require specialized equipment.
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.
Rapid test detects NHP in penaeid shrimp
A rapid lateral-flow immunoassay using monoclonal antibody combinations can identify necrotizing hepatopancreatitis (NHP) infection in less than 15 minutes.
Black tiger shrimp domestication advances
The production of early generations of domesticated broodstock in open-environment ponds may have hampered the domestication of black tiger shrimp.
Oysters and the impacts of climate change
In recent decades, mass summer mortality in oyster aquaculture has become widespread, with 50 percent of crops lost in a given year. Losses are often associated with spawning, which is normally seasonal but highly temperature-dependent.
How to prepare and interpret blood smears
A significant part of any hematological evaluation of fish is the preparation, microscopic examination and interpretation of stained blood smears.
Enhancing immunity: Tools for protecting farmed shrimp
Shrimp do not produce antibodies and therefore do not remember prior exposure to pathogens, a critical component of long-term protective immunity.
Wastewater reuse supports paddlefish project
A pilot project in Kentucky that uses wastewater effluent and decommissioned tanks at a water treatment plant has cultured over 70,000 phase II paddlefish.
Streptococcosis in tilapia
Tilapia infected with streptococcosis pathogens exhibit similar clinical signs, including lethargy, abnormal swimming and lack of appetite.
Specific pathogen free status advances shrimp culture
The advent of specific pathogen free Pacific white shrimp became a powerful tool for lessening the impacts of diseases in aquaculture.
Selective breeding can improve fish welfare
Although selection in fish is progressing rapidly, slower adaption to captivity over several generations can limit animal welfare problems.
Integrated larval-nursery system for California halibut
Hubbs-SeaWorld Research Institute developed an integrated larval-nursery recirculating aquaculture system for California halibut utilizing shallow raceways for juvenile culture.
Larviculture protocols for cobia
While Asia’s more extensive approaches for cobia larviculture are effective, more intensive methods are used in the Americas. Most facilities still rely heavily upon wild-capture broodstock.
Shrimp hybrids outperform parents in Brazil studies
In Brazil, shrimp hybrids – crosses of imported specific pathogen-free lines and a genetically improved and locally adapted line – outperform their parents.
Challenges to commercializing shrimp triploidy
Once satisfactory performance is demonstrated in commercial larval rearing and grow-out, automated induction will finalize the triploidy commercialization.
Genetically standardized trout stock to improve research
To alleviate problems associated with conducting research on fish of unknown and likely diverse genetic backgrounds, a collaborative project has been established to produce a stock of rainbow trout with a defined genetic background for use in fish nutrition research.
