Characterization of the effects of triclosan on sperm and embryos of Mytilus and Perna mussel species

Anne Rolton et al.

Summary: This study investigated the effects of triclosan (TCS) on the early life stages of the Greenshell mussel (GSM) and the blue mussel (BM). The results showed that TCS increased reactive oxygen species (ROS) production in sperm, reduced fertilization success and larval size, and increased larval mortality. Fertilization success in GSM was only affected at the highest TCS concentration, but the development of larvae derived from exposed sperm was affected even at the lowest concentrations, highlighting the importance of assessing the sensitivity of contaminants at different developmental stages.

Understanding the combined effects of multiple stressors: A new perspective on a longstanding challenge

Enrico Pirotta et al.

Summary: This article reviews the research on the effects of multiple stressors on wildlife populations and ecosystems, and proposes a conceptual framework for assessing the combined effects of these stressors. The article points out that different approaches have different assumptions about mechanisms, and that emphasis on mechanisms can improve analytical precision and predictive power but may introduce bias. Using an example, the article demonstrates how this framework can be formalized into specific analytical methods. The article argues that the goal of adaptive management should be to find the most practical and effective ways to remove or reduce the impacts of specific combinations of stressors.

Effects of Harmful Algal Blooms on Fish and Shellfish Species: A Case Study of New Zealand in a Changing Environment

Anne Rolton et al.

Summary: Harmful algal blooms (HABs) have significant impacts on aquatic species, especially in the aquaculture industry in New Zealand (NZ). This review focuses on HAB species that bloom globally and in NZ, examining their effects on commercially important shellfish and fish. The study highlights the association between Karenia spp. blooms and fish and shellfish mortalities in NZ, as well as the sub-lethal effects of Alexandrium spp. on shellfish. Climate change and human activities may further alter HAB population dynamics and impact aquatic species. The paper also discusses the potential future blooms of HAB species in NZ and their harmful effects on marine life. The use of environmental DNA (eDNA) and bioassays are practical tools for early detection and rapid screening of problem HAB species, as demonstrated in HAB monitoring of aquaculture production sites. This research emphasizes the need to study the combined effects of climate change and HABs on cultured species using local, recent HAB strains to inform effective stock management strategies.

Overview of Australian and New Zealand harmful algal species occurrences and their societal impacts in the period 1985 to 2018, including a compilation of historic records

Gustaaf M. Hallegraeff et al.

Summary: Australia and New Zealand both have similarities and differences in terms of harmful algal species occurrences and their impacts on human society, such as toxic shellfish toxin production. While both countries have experienced harmful algal events, the predominant seafood toxin syndromes differ between Australia and New Zealand.

Predicting the Effects of Climate Change on the Occurrence of the Toxic Dinoflagellate Alexandrium catenella Along Canada's East Coast

Aude Boivin-Rioux et al.

Summary: The study reveals that Alexandrium catenella's bloom frequency and extent are expected to increase in the future, with changes in bloom seasonality. Under one climate scenario, the duration and spatial range of A. catenella blooms are predicted to expand each year, possibly posing threats to future marine ecosystems and industries.

Allelochemicals of Alexandrium minutum: Kinetics of membrane disruption and photosynthesis inhibition in a co-occurring diatom

Marc Long et al.

Summary: Allelopathy is an efficient strategy used by some microalgae to outcompete other species, where allelochemicals from toxic dinoflagellates have deleterious effects on diatoms, giving a competitive advantage to the dinoflagellates. The study found that these unknown chemicals induced depolarization of diatom cytoplasmic membranes and impaired photosynthesis through inhibition of electron transfer, but the exact mechanisms and molecular targets remain unknown. Further research is needed to clarify the relationship between cytoplasmic membranes and inhibition of photosynthetic electron transfer.

Marine invertebrate interactions with Harmful Algal Blooms-Implications for One Health

Andrew D. Turner et al.

Summary: Harmful algal blooms, caused by dinoflagellates and cyanobacteria, have significant impacts on human, animal, and ecosystem health, primarily through the production of algal toxins that bioaccumulate in filter-feeding organisms and transfer through the food web. New science and interdisciplinary assessment are necessary to ensure a continued increasing supply of aquaculture foodstuffs for future generations in the face of expected more frequent and intense HAB outbreaks.

Unknown Extracellular and Bioactive Metabolites of the Genus Alexandrium: A Review of Overlooked Toxins

Marc Long et al.

Summary: Various species of Alexandrium can produce bioactive compounds, including uncharacterized bioactive extracellular compounds (BECs) which may have significant ecological impacts. Due to a lack of information on BECs in experimental strains, contrasting results in literature make it impossible to distinguish between the effects of PSTs and BECs. Further research is needed to identify the nature of Alexandrium BECs and understand their potential ecological importance and collateral damage to marine organisms.

Life cycle informed restoration: Engineering settlement substrate material characteristics and structural complexity for reef formation

Ralph J. M. Temmink et al.

Summary: Ecosystems are degrading globally, leading to severe consequences. Restoration is crucial for regaining ecosystem services and preserving biodiversity, but can be expensive and prone to failure, especially in harsh environments. Innovative approaches like artificial biodegradable reefs can enhance restoration efforts by mimicking emergent traits that ameliorate multiple bottlenecks over the reef-forming organism's life cycle, proving to be cost-effective and efficient tools for restoring ecosystems dominated by habitat modifiers facing multiple life stage-dependent challenges.

The toxic dinoflagellate Alexandrium minutum affects oyster gamete health and fertilization potential

Justine Castrec et al.

Summary: The study revealed that the bioactive extracellular compounds produced by Alexandrium minutum have significant cellular toxicity on oyster gametes, leading to reduced viability and fertilization capacity when exposed to high densities of A. minutum. Specifically, the strain producing BEC showed stronger inhibitory effects on sperm motility and ROS production in oocytes, resulting in decreased fertilization at concentrations as low as 2.5 x 103 cells mL-1.

Opportunities and challenges for upscaled global bivalve seafood production

David F. Willer et al.

Summary: The slow growth in the bivalve mariculture sector is mainly due to low production efficiency, food safety concerns, and limited consumer demand. By improving production efficiency, enhancing food safety, and offering more appealing food products, the bivalve industry could potentially meet the increasing demand for nutritious and sustainable seafood.
