Marine aquaculture (mariculture), the farming of marine species, is currently a relatively small contributor to the United States' seafood industry. There is tremendous potential for growth in this sector and increasing interest in advancing the industry through supportive federal and state policies as well as concerns about how to best manage potential negative impacts or unsustainable development. While some mariculture is conducted in land-based tanks as well as saltwater ponds, and there are pilot projects and ongoing applications to commence mariculture operations in federal waters, the majority of mariculture activities occur within state waters (typically, 3 nautical miles, or 5.

Article Synopsis
  • Scientists are studying how well marine protected areas (MPAs) are doing in protecting fish and sea creatures.
  • They use different methods to compare the number of animals inside the MPA to those outside to see if the MPA is successful.
  • Overall, most studies show that MPAs help increase the number and size of sea creatures, but not all studies have enough long-term information to confirm this impact.

Article Synopsis
  • Researchers called "embedded researchers" help improve public health by using research while working with local government. They need clear ways to be evaluated and expected to do their jobs.
  • After talking to 17 embedded researchers, we found that their skills and connections are important for success, but they face challenges like not having enough money or time.
  • To do well, embedded researchers need to be good at both research and communicating, and they should have support and opportunities to grow in their careers.

Background: Embedding researchers into policy and other settings may enhance research capacity within organisations to enable them to become more research active. We aimed to generate an evidence map on evaluations of embedded researcher interventions to (i) identify where systematic reviews and primary research are needed and (ii) develop conceptual understandings of 'embedded researchers'. We define 'embedded researchers' through a set of principles that incorporate elements such as the aim of activities, the types of relationships and learning involved, and the affiliations and identities adopted.

Marine protected areas (MPAs) are widely used for ocean conservation, yet the relative impacts of various types of MPAs are poorly understood. We estimated impacts on fish biomass from no-take and multiple-use (fished) MPAs, employing a rigorous matched counterfactual design with a global dataset of >14,000 surveys in and around 216 MPAs. Both no-take and multiple-use MPAs generated positive conservation outcomes relative to no protection (58.

Article Synopsis
  • Improving teamwork and sharing ideas between public health workers and universities can help make research more useful for real-life policies.
  • "Embedded researchers," who work closely with both decision-makers and researchers, can help connect research with practice, but we need to learn more about how they do this.
  • Our study looked at interviews with these researchers in local public health teams, showing that early on, they focus on building trust and understanding their new work environment, which is super important for making meaningful changes in public health research.

Aims: Females and males of all ages are affected by epilepsy; however, unlike many clinical studies, most preclinical research has focused on males. Genetic variants in the voltage-gated sodium channel gene, SCN8A, are associated with a broad spectrum of neurological and epileptic syndromes. Here we investigate sex differences in the natural history of the Scn8a-N1768D knockin mouse model of pediatric epilepsy.

Hyper-secretion and/or hyper-concentration of mucus is a defining feature of multiple obstructive lung diseases, including chronic obstructive pulmonary disease (COPD). Mucus itself is composed of a mixture of water, ions, salt and proteins, of which the gel-forming mucins, MUC5AC and MUC5B, are the most abundant. Recent studies have linked the concentrations of these proteins in sputum to COPD phenotypes, including chronic bronchitis (CB) and acute exacerbations (AE).

Article Synopsis
  • Coral reefs are facing problems because of both natural changes and human activities, leading to a loss of coral and an increase in algae.
  • Two main reasons for this shift to more algae are too many nutrients from things like fertilizers and overfishing of fish that eat algae.
  • In a study in Moorea, French Polynesia, scientists found that the ways fishing and nutrient pollution affect reefs are different depending on where you are, showing that managing these problems needs to be specific to different areas.

Coral reef fisheries are vital to the livelihoods of millions of people worldwide but are challenging to manage due to the high diversity of fish species that are harvested and the multiple types of fishing gear that are used. Fish traps are a commonly used gear in reef fisheries in the Caribbean and other regions, but they have poor selectivity and frequently capture juvenile fish, impacting the sustainability of the fishery. One option for managing trap fisheries is the addition of escape gaps, which allow small fish to escape.

Article Synopsis
  • Marine Protected Areas (MPAs) are special ocean places that help keep marine life safe and healthy while also helping people.
  • There are many types of MPAs, and this can make it confusing to know how well they work, so a new guide called The MPA Guide has been created to help people understand them better.
  • This guide shows how to set up and improve MPAs, what they can do for nature and people, and what needs to happen for them to succeed.

Dramatic coral loss has significantly altered many Caribbean reefs, with potentially important consequences for the ecological functions and ecosystem services provided by reef systems. Many studies examine coral loss and its causes-and often presume a universal decline of ecosystem services with coral loss-rather than evaluating the range of possible outcomes for a diversity of ecosystem functions and services at reefs varying in coral cover. We evaluate 10 key ecosystem metrics, relating to a variety of different reef ecosystem functions and services, on 328 Caribbean reefs varying in coral cover.

Climate change is causing range shifts in many marine species, with implications for biodiversity and fisheries. Previous research has mainly focused on how species' ranges will respond to changing ocean temperatures, without accounting for other environmental covariates that could affect future distribution patterns. Here, we integrate habitat suitability modeling approaches, a high-resolution global climate model projection, and detailed fishery-independent and -dependent faunal datasets from one of the most extensively monitored marine ecosystems-the U.

Food security remains a principal challenge in the developing tropics where communities rely heavily on marine-based protein. While some improvements in fisheries management have been made in these regions, a large fraction of coastal fisheries remain unmanaged, mismanaged, or use only crude input controls. These quasi-open-access conditions often lead to severe overfishing, depleted stocks, and compromised food security.

Coral reef social-ecological systems worldwide face major impacts from climate change, and spatial variation in vulnerability is driven by differential exposure to climatic threats, ecological and socio-economic sensitivity to those threats, ecological recovery potential, and socio-economic adaptive capacity. We assess variation in social-ecological vulnerability to climate change-induced coral bleaching, specifically for reef-based fisheries and tourism, of islands throughout the insular Caribbean, thus providing the first region-wide quantitative analysis of island-scale social-ecological vulnerability to coral bleaching. We show that different components of vulnerability have distinct spatial patterns and that variability in overall vulnerability is driven more by socio-economic than ecological components.

The transformation of coral reefs has profound implications for millions of people. However, the interactive effects of changing reefs and fishing remain poorly resolved. We combine underwater surveys (271 000 fishes), catch data (18 000 fishes), and household surveys (351 households) to evaluate how reef fishes and fishers in Moorea, French Polynesia responded to a landscape-scale loss of coral caused by sequential disturbances (a crown-of-thorns sea star outbreak followed by a category 4 cyclone).

Environmental conservation initiatives, including marine protected areas (MPAs), have proliferated in recent decades. Designed to conserve marine biodiversity, many MPAs also seek to foster sustainable development. As is the case for many other environmental policies and programs, the impacts of MPAs are poorly understood.

Marine protected areas (MPAs) are increasingly being used globally to conserve marine resources. However, whether many MPAs are being effectively and equitably managed, and how MPA management influences substantive outcomes remain unknown. We developed a global database of management and fish population data (433 and 218 MPAs, respectively) to assess: MPA management processes; the effects of MPAs on fish populations; and relationships between management processes and ecological effects.

Marine aquaculture is expanding into deeper offshore environments in response to growing consumer demand for seafood, improved technology, and limited potential to increase wild fisheries catches. Sustainable development of aquaculture will require quantification and minimization of its impacts on other ocean-based activities and the environment through scientifically informed spatial planning. However, the scientific literature currently provides limited direct guidance for such planning.

Article Synopsis
  • Climate change is affecting fish populations and the people who rely on them, and it's only going to get worse.
  • Regulations on fishing can help these communities deal with the impacts of climate change, but we need better ways to study how these rules work.
  • The study looks at different types of fishing rules to see how they help or hurt fish populations; it finds that some rules are better for keeping fish populations healthy than others.
