Pat Reynolds, one of the world’s preeminent lumpfish researchers, believes that – despite a number of welfare issues and a slight dip in their popularity – the species merits a prominent place in the list of ways to control sea lice on salmon farms.
Jim Treasurer, co-editor of a new comprehensive publication on sea lice, looks back on over three decades of working to combat aquaculture’s best known and most costly ectoparasites.
The environmental impacts of aquaculture are often in the spotlight. The need for sustainable practices is now firmly embedded in the minds of the public, governments and industry – but this sometimes presents trade-offs in fish welfare.
Asia’s shrimp farmers need to reboot their attitude to biosecurity and stocking densities, argues Robins McIntosh, in a follow-on to Monday’s article on the dangers of disinfection*.
The overuse of disinfectants, coupled with farmers’ willingness to exceed their systems’ carrying capacities, have been key factors in the downfall of the Asian shrimp sector over the last decade, according to Robins McIntosh*.
Flexible ingredient formulations, enzymes, optimised microbiomes and genetics are playing their part in bringing multiple farmed fish species closer to precision nutrition, according to Alltech’s global manager of aquaculture research.
Ecuador’s relatively extensive shrimp farming techniques have ensured that their shrimp are robust enough to cope with the presence of pathogens that would be disastrous in most parts of Asia – allowing them to continuously produce shrimp sustainably for decad…
A new paper argues that there’s an urgent need to improve understanding of the genetic mechanisms involved in host resistance to whitespot syndrome virus (WSSV) and sea lice – two of the greatest health challenges facing shrimp and salmon farming respectively.…
A traditional Chinese herbal prophylactic, containing bioavailable phytonutrients recovered from the Camellia sinensis tea bush, has been shown to protect shrimp from outbreaks of AHPND and WSSV.
Researchers are beginning to highlight the potential of immunostimulants as a sustainable disease prevention strategy for shrimp aquaculture. Here’s a run-down of how these molecules work, their origins and how they can be used to combat outbreaks of white spo…
Shrimp that have been bred for their resistance to disease and ability to thrive despite environmental challenges should be valued as highly – if not more highly – than those bred for their growth rates in many parts of Indonesia.
Emerging research has shown that nutraceuticals in aquafeed can delay the onset and progress of clinical signs of amoebic gill disease (AGD) in farmed Atlantic salmon.
My objective in this article is to challenge pathologists, immunologists and farmers by asking for a critical analysis on the application of a simple temperature manipulation, hyperthermia, to boost the innate immune system of fish.
