Journal Articles

Despite decades of research on lobster species’ biology, ecology, and microbiology, there are still unresolved questions about the microbial communities which associate in or on lobsters under healthy or diseased states, microbial acquisition, as well as microbial transmission between lobsters and between lobsters and their environment. There is an untapped opportunity for metagenomics, metatranscriptomics, and metabolomics to be added to the existing wealth of knowledge to more precisely track disease transmission, etiology, and host-microbe dynamics. Moreover, we need to gain this knowledge of wild lobster microbiomes before climate change alters environmental and host-microbial communities more than it likely already has, …

The Synergistic Effects Of Elevated Temperature And Co2 - Induced Ocean Acidification Reduce Cardiac Performance And Increase Disease Susceptibility In Subadult, Female American Lobsters Homarus Americanus H. Milne Edwards, 1837 (Decapoda: Astacidea: Nephropidae) From The Gulf Of Maine, Amalia M. Harrington, Robert Harrington, Heather J. Hamlin, Deborah A. Bouchard

Journal Articles

Increased greenhouse gas emissions have caused rapid ocean warming (OW) and reduced ocean pH via acidification (OA). Both OW and OA will likely impact marine crustaceans, but they are often examined in isolation. We conducted an environmental-stressor experiment to understand how exposure to current summer conditions (16 °C, pH 8.0), OW only (20 °C, pH 8.0), OA only (16 °C, pH 7.6), or both acidification and warming, OAW (20 °C, pH 7.6), differentially influence thermal physiology and immune response of female subadults of the American lobster, Homarus americanus H. Milne Edwards, 1837. Following a 42 d exposure, cardiac performance was …

A Hedonic Analysis Of The Impact Of Marine Aquaculture On Coastal Housing Prices In Maine, Keith S. Evans, Xuan Chen, Christina A. Robichaud

Converting coastal waters to farmed production of seafood may generate conflicts with other resource users. This study explores the impact of marine aquaculture development on coastal homeowners. Using single-family home sales from 2012–2014 and spatial data on coastal aquaculture activity, we employ hedonics to assess the impacts of mariculture development in three study areas of Maine, USA. Our results suggest modest impacts on residential property values with significant spatial variation across study areas. This spatial variation represents a challenge for managers and highlights the potential benefits from coordinating the development of aquaculture to balance resource users' objectives with industry growth.

Mechanistic Understanding Of Ocean Acidification Impacts On Larval Feeding Physiology And Energy Budgets Of The Mussel M. Californianus, Matthew W. Gray, Chris J. Langdon, George G. Waldbusser, Burke Hales, Sean Kramer

Ocean acidification (OA) - a process describing the ocean’s increase in dissolved carbon dioxide (PCO2) and a reduction in pH and aragonite saturation state (Ωar) due to higher concentrations of atmospheric CO2 – is considered a threat to bivalve mollusks and other marine calcifiers. While many studies have focused on the effects of OA on shell formation and growth, we present findings on the separate effects of PCO2, Ωar, and pH on larval feeding physiology (initiation of feeding, gut fullness, and ingestion rates) of the California mussel Mytilus californianus. We found elevated PCO2 delays initiation of feeding, while gut fullness …

Journal Articles

Bivalve aquaculture relies on naturally occurring phytoplankton, zooplankton, and detritus as food sources, thereby avoiding external nutrient inputs that are commonly associated with finfish aquaculture. High filtration rates and concentrated bivalve biomass within aquacul- ture operations, however, result in intense biodeposition of particulate organic matter (POM) on surrounding sediments, with potential adverse environmental impacts. Estimating the net deposi- tional flux is difficult in shallow waters due to methodological constraints and dynamic processes such as resuspension and advection. In this study, we combined sediment trap deployments with simulations from a mechanistic sediment flux model to estimate seasonal POM deposition, resus- pension, …

Marine Stewardship Council Science Series Best Practices For Managing, Measuring And Mitigating The Benthic Impacts Of Fishing - Part 2, Chris Grieve, Damian C. Brady, Hans Polet

Journal Articles

In a previous paper, Review of habitat dependent impacts of mobile and static fishing gears that interact with the sea bed (2014) we offered definitions for benthic habitat, fishing gear and fisheries management and a way of thinking about the challenge of understanding best practices for measuring, monitoring, managing and mitigating benthic impacts of fishing in the context of the MSC’s certification requirements. These informed our review in the previous paper’s classification of habitats and fishing gears and helped us highlight likely variations in benthic impact depending on habitat and gear used (Grieve, Brady & Polet, 2014). In this paper, …

The role of bivalve mariculture in the CO2 cycle has been commonly evaluated as the balance between respiration, shell calcium carbonate sequestration and CO2 release during biogenic calcification. However, this approach neglects the ecosystem implications of cultivating bivalves at high densities, e.g. the impact on phytoplankton dynamics and benthic-pelagic coupling, which can significantly contribute to the CO2 cycle. Therefore, an ecosystem approach that accounts for the trophic interactions of bivalve aquaculture, including dissolved and particulate organic and inorganic carbon cycling, is needed to provide a rigorous assessment of the role of bivalve mariculture in the CO2 cycle. On the other …
