Aquatic disease in New Zealand: synthesis and future directions

Henry S. Lane et al.

Summary: Dedicated studies on aquatic disease in New Zealand began in 1974, with a focus on aquatic disease ecology and diseases of commercial species. However, aquatic disease in New Zealand has not received much attention and there is a need to address knowledge gaps on future threats such as climate change, invasive species, and pollution. More attention from the wider marine science community is needed.

Emerging Parasitic Protists: The Case of Perkinsea

Sarah Itoiz et al.

Summary: The last century has seen an increase in the emergence of new diseases, leading to a loss of biodiversity. Perkinsea is a microeukaryotic parasitic phylum with a broad range of hosts. In marine environments, there are currently three lineages infecting dinoflagellates, mollusks, and fish, while in freshwater environments, there is only one lineage infecting frog tadpoles. High-throughput sequencing methods have revealed that Perkinsea is more diverse than previously described, especially in freshwater environments. This review summarizes the biological and ecological traits of Perkinsea and highlights their diversity and ubiquity in association with a wide range of hosts.

Performance characteristics of two real-time TaqMan polymerase chain reaction assays for the detection of WSSV in clinically diseased and apparently healthy prawns

Nicholas J. G. Moody et al.

Summary: This study aimed to validate the performance characteristics of two real-time PCR assays for detecting white spot syndrome virus (WSSV). The results showed that both assays had high sensitivity and specificity in detecting WSSV. Additionally, the assays demonstrated good repeatability in different sample types, indicating their reliability.

The loss of spat following seeding onto coastal GreenshellTM mussel (Perna canaliculus) farms

Bradley M. Skelton et al.

Summary: The early stages of mussel aquaculture are often inefficient, with significant losses of seed mussels observed shortly after seeding out. Environmental conditions seem to have minimal impact on secondary settlement behavior of spat, indicating improvements in spat retention may come from altering deployment methods.

Aquatic pathogens and biofouling: pilot study of ostreid herpesvirus 1 translocation by bivalves

M. Fuhrmann et al.

Summary: The laboratory experiments showed that Pacific oysters could transmit OsHV-1 virus through biofouling, indicating the complexity of pathogen spread and the need for further research to inform future risk assessments and management strategies.

Environmental factors drive the release of Perkinsus marinus from infected oysters

Sarah A. Gignoux-Wolfsohn et al.

Summary: Environmental factors such as temperature and salinity influence the release of parasites from infected oysters to the water column, contributing to fluctuations in parasite abundance. The study found that temperature and salinity have different effects on parasite abundance over time, with infected oysters significantly enhancing parasite levels in the water column under specific conditions.
