Study tests disinfectant alternatives to formalin
Formalin use is a common fish parasite control, but the chemical’s potential work safety and ecological impacts are leading to a search for alternatives.
Post-harvest quality of freshwater prawns, part 2
Freshwater shrimp can contain pathogenic bacteria that cause illness unless care is exercised by producers, retailers and consumers. Many of the human pathogens can survive frozen storage, but are killed or inactivated by thermal processes.
On the Job: Scottish salmon stalwart signs off after 41 years
As Steve Bracken retires after more than four decades of fish farming, he reflects on his career producing Scottish salmon and shares his well-earned perspectives on aquaculture’s past and future.
Strategies for managing large integrated shrimp farms
Integrated shrimp farming is desirable due to its ability to provide food safety and traceability. Production planning is the most essential exercise in integrated systems.
Organic matter for pond fertilizer
Animal manures, grasses and other organic matter have been widely used as fertilizers in aquaculture ponds. The fertilizers decompose and release nutrients that promote the growth of phytoplankton and enhance the base of the food web.
Backup oxygen, power systems essential insurance
Although essential, emergency backup systems do not have to be complicated or expensive. For power loss, automated phone dialers alert off-site staff. Backup electric generators provide needed power for aerators, pumps and other equipment.
Grassroots oyster aquaculture provides habitat for juvenile blue crabs
Juvenile blue crabs prefered floats containing three-dimensional structure provided by oysters and shells, which helped provide refuge from predators.
Purging, processing freshwater crawfish
In crawfish production, purging systems can improve water quality, reduce contaminants and improve the physical factors of the product valued by consumers.
Cost to benefit, fish skin yields unique gelatin products
Fish skin can be processed into food-grade gelatin. Unlike gelatins made from cattle and pig skins, those from coldwater fish remain liquid when not refrigerated.
Bangladesh seeks more buck for its ‘bagda’
As more than 80 percent of Bangladeshi shrimp exports already go to EU markets, a consultation meeting involving buyers from the bloc and Bangladesh industry stakeholders and authorities was held at the end of last month in Utrecht, the Netherlands.
Proper processing destroys V. parahaemolyticus in seafood
V. parahaemolyticus presents a food safety hazard for those who consume raw shellfish. The organism can grow post-harvest in some shellfish species, especially oysters.
Researchers examine antimicrobial resistance potential in aquaculture
The influence of antibiotics in fish and their effects on the gut microbiome aren’t well understood, says research team examining antimicrobial resistance.
Shrimp farming in Bangladesh
As Bangladesh strives for gains in exports, its shrimp industry is addressing production efficiency, disease control and responsible development.
Chlorine dioxide offers seafood treatment alternative to aqueous chlorine
Chlorine dioxide effectively reduces microorganisms on seafood and could be used as a processing treatment to improve shelf life and product safety.
Beyond HACCP: Total procedures manuals, Part 3
Processors maintain facility and product security via HACCP procedures and supporting documentation that control physical security, employees and visitors.
Shrimp culture in India: Hatchery, farm, industry issues

Probiotics’ enhancement of soil, water quality examined
Probiotics used as bottom soil and water quality enhancers are primarily cultures of living bacteria, enzyme preparations, or the two combined.
Microbial flora of aquaculture products
The microbial flora of farmed seafood products, particularly the microorganisms considered human pathogens, are important to individuals and agencies.
