High‐Throughput Sequencing in Aquaculture Disease Investigations: Challenges and Opportunities for ImplementationNARA Subscribed
The current generation of sequencing technologies can produce terabases of data with exceptional accuracy and speed, at a fraction of the cost of older methods. Despite this unprecedented power, adoption into aquaculture health management presents several challenges, including identifying where such capability may be optimally deployed. Here we synthesise discussions from a structured expert workshop held at the 2025 Aotearoa...
Lymphocystis Disease in Endemic Aotearoa New Zealand Bully ( Gobiomorphus cotidianus )NARA Subscribed
We detected lymphocystis disease virus (LCDV) for the first time in an Aotearoa New Zealand freshwater environment, from an individual common bully, toitoi, Gobiomorphus cotidianus (Eleotridae). Dinah's bully, Gobiomorphus dinae , and Kaharore bully, Gobiomorphus mataraerore , also exhibited gross nodular lesions on the fins but were not sampled. Histopathology of G. cotidianus nodular lesions revealed hypertrophic lymphocysti...
Background and aims Agricultural soils in semi-arid sub-Saharan Africa are often low in soil organic carbon (SOC) and nitrogen (N), making them vulnerable to degradation and threatening food security of smallholder farmers. Conservation agriculture practices such as mulching are promoted as climate-resilient strategies to improve soil fertility, but it remains unclear whether these practices improve soil biogeochemical propert...
Although birds have been used globally as bioindicators of heavy metals, the determinants and physiological consequences of their exposure to heavy metals remain poorly understood. The American Robin ( Turdus migratorius ) is a common songbird in a variety of habitats across most of North America that could serve as an ideal sentinel of heavy metal contamination. We evaluated how robin exposure to lead (Pb) varied regionally,...
Tilapia Lake Virus (TiLV) is a significant threat to global tilapia aquaculture, highlighting the need for rapid and accurate diagnostic methods to manage outbreaks and minimise economic losses. This study presents the development and partial validation of a one‐pot assay integrating RT‐LAMP with the CRISPR/Cas12b system for sensitive and specific TiLV detection. This assay amplifies viral RNA using RT‐LAMP, while CRISPR/Cas12...
Risk of Spread of Megalocytivirus pagrus1 (Infectious Spleen and Kidney Necrosis Virus) From Frozen FilletsNARA Subscribed
Infectious spleen and kidney necrosis virus (ISKNV) is a significant threat to global aquatic food security by causing large‐scale mortality in the aquaculture of tilapia ( Oreochromis niloticus ) and mandarin fish ( Siniperca chuatsi ). ISKNV is a genogroup of Megalocytivirus pagrus1 , along with RSIV and TRBIV, and their recent listing as WOAH‐notifiable diseases highlights the need to assess spread pathways to prevent exoti...
Ecology of community reassembly: Movements and diets of megafauna during a decade of restoration in MozambiqueNARA Subscribed
The last decade has brought a worldwide surge of interest in rewilding—the repopulation of large herbivores and carnivores—as a strategy for conserving species and reviving ecosystem functions. Rewilding initiatives, if closely monitored, can provide unique insights into the ecology of the world's largest animals at otherwise impossible spatial and temporal scales. Capitalizing on these opportunities, and developing a knowledg...
The influence of aquaculture translocations and escapees on the genetics of wild stocks of Lates calcarifer in Taiwan and Sri LankaNARA Subscribed
Advances in aquaculture have significantly enhanced food production and contributed to global food security. However, the selective pressures for aquaculture are strong and divergent compared to those occurring in natural systems, and displacement of standing genetic backgrounds by aquaculture backgrounds is a conservation concern across various species. The Asian sea bass or barramundi ( Lates calcarifer ) is a widely propaga...
Contrasting Genomic Responses of Hydrothermal Vent Animals and Their Symbionts to Population Decline After the Hunga Volcanic EruptionNARA Subscribed
Genetic bottlenecks are evolutionary events that reduce the effective size and diversity of natural populations, often limiting a population's ability to adapt to environmental change. Given the accelerating human impact on ecosystems worldwide, understanding how populations evolve after a genetic bottleneck is becoming increasingly important for species conservation. Ash deposits from the 2022 Hunga volcanic eruption in the S...
