Abalone are valuable commercial marine gastropods, supporting both aquaculture and fishery markets. An important ecological aspect of their survival and physiological performance in a given habitat is a complex and balanced symbiotic relationship with microbes in their digestive system. 16S rRNA Illumina MiSeq sequencing was used to investigate the microbial composition of New Zealand abalone ( Haliotis iris ) digestive region...

Green‐lipped mussel ( Perna canaliculus ) aquaculture is vulnerable to environmental changes, which are increasingly being studied to pinpoint physiological, economic and ecological threats. This study utilised a targeted liquid chromatography‐mass spectrometry metabolomics approach, focusing on the central carbon metabolism, to examine the metabolic response of P. canaliculus haemolymph to heat stress (30°C) and multi‐point r...

Fungicide resistance is an escalating threat to barley ( Hordeum vulgare L.) production worldwide. To evaluate use patterns and potential resistance risks, fungicide application data from the South African national barley production traceability and compliance platform, called the Barley Passport (2021–2024) were analysed. Program intensity was consistently high, with three-application regimes dominating and two-application pr...

New Zealand abalone (Haliotis iris) holds ecological, economic, and cultural value, with wild stocks supporting fisheries and an emerging aquaculture industry. Wild-caught adult abalone are often used as broodstock, but captivity can affect spawning and offspring quality. This study is the first to profile wild and farmed H. iris broodstock using histology, proximate composition, microbiome, and metabolomics analyses. Histolog...

Escherichia coli is widely used as an indicator of faecal contamination, as it is assumed that faeces from warm-blooded animals is the primary source of E. coli in the environment. However, various studies have shown that E. coli can survive and multiply in environmental niches, including soil, sand and sediment. E. coli can be assigned to eight main phylogroups but environmental E. coli are associated primarily with phylogrou...

Abalone is a gourmet seafood with a high commercial value, particularly when obtained as a live product. During live transportation, abalone encounter stressors causing biochemical modifications to tolerate the changes. Using semi‐targeted metabolomics, this study characterised the left and right gill metabolite profiles of Blackfoot abalone, Haliotis iris , following transportation (48 h) and recovery (48 h). This study repor...

For more than a century, bacterial infections caused by Vibrio spp. have affected various species of mussels around the world, with limited insights into the responses implemented by mussels against these infections. A combination of chemical analyses and carefully selected biological endpoints from haemolymph and tissues can be used to identify the welfare status of mussels and potentially protect aquatic ecosystems from cata...

The endemic, green‐lipped mussel ( Perna canaliculus ), trademarked as Greenshell™ mussel, contributes most to the New Zealand aquaculture industry based on tonnage and export value. Research on mussel immunity is motivated greatly by economical and biosecurity necessities. Indeed, mussel aquaculture is threatened by pathogenic micro‐organisms and environmental stressors. As such there is a need to understand the mechanisms th...

Background: The decrease in the production of Argopecten purpuratus scallops in Chile is linked to extensive larval deaths in hatcheries caused by bacterial pathogens, particularly Vibrio genus, threatening sustainability. Traditional antibiotic practices raise concerns, urging research on eco-friendly strategies like bacterial probiotics. This study explores the metabolic responses of scallop larvae to Vibrio bivalvicida and...
