Summary: The European aquaculture industry started Atlantic halibut aquaculture in the 1980s due to its favorable growth rate and high market value. After 12 years and a total investment of $2 million USD, Chilean aquaculture facilities were finally equipped to rear Atlantic halibut. Infrastructure is now in place to support the development of a sustainable marine aquaculture industry for this species.

Summary: The electron velocity distribution functions driven by inverse bremsstrahlung heating were measured to be non-Maxwellian using a novel angularly resolved Thomson-scattering instrument. The shape of the tail in the distribution functions is influenced by the uniformity of the laser heating when the laser heating rate dominates over the electron-electron thermalization rate. Simulations with the particle code QUARTZ demonstrate the impact of laser heating uniformity on the distribution functions.

Summary: In this study, a robotic fish named KUFish was developed to mimic the swimming behavior of flying fish. The KUFish could swim at a speed of 0.68 m/s and leap out of the water at 1.35 m/s. The passive dynamic stability of the robot was achieved through symmetric mass distribution, positive buoyancy, and lower center of gravity. The results from this research could be beneficial for the development of flying-fish-like swimming robots in the future.

Summary: The study focused on microplastics pollution in Dafeng River in Guangxi Province, China. The research found that while the river had relatively low microplastics pollution levels, aquatic organisms, particularly fish, showed more severe contamination. This highlights the need for attention to microplastics pollution in organisms of remote rivers.

Summary: This study aimed to understand the relationships between hydraulic characteristics and fish assemblage in the Three Gorges Reservoir, providing a scientific basis for the protection and restoration of river habitats. The research showed that fish preferred deep pools with a minimum and maximum velocity requirement of 0.6 m/s and 1.2 m/s respectively, taking into consideration both hydrodynamic conditions and sediment transport.

Summary: This paper introduces a laser scanning-based three-dimensional reconstruction algorithm for simple and effective measurements in vertical bubbly flow. It captures a series of slice images using a high-speed camera and proposes a modified two-dimensional cross-correlation algorithm for bubble extraction and matching. Based on the reconstructed flow structures, bubble velocities and their distribution in different scanning cycles are measured. Statistically, bubble sizes are mainly concentrated within 1.8-2.2 mm. The void fractions are calculated for various gas flow rates with relative errors primarily within +/- 10%, and the average void fraction has a relative error of less than 8%, indicating higher reconstruction precision.

Summary: It has been found that the quality of drinking water is deteriorated during its transportation through the drinking water distribution system (DWDS) due to the detachment of biofilm from the pipe wall to the bulk water. This study investigates the effects of hydraulic conditions, such as flow velocity and direction, on biofilm formation and detachment. The results show that fluctuant flow velocity conditions lead to the thickest biofilm and the lowest adhesion force, and the reverse flow condition causes biofilm detachment. This research enhances our understanding of the influence of different hydraulic conditions on biofilm in the DWDS and provides insights on how to operate the DWDS effectively to minimize biofilm detachment.

Summary: Laser quenching is an excellent method for gear tooth surface quenching, providing high efficiency, environmental friendliness, and consistent performance. By adjusting the laser scanning velocity and power, variable depth quenching can be achieved. The study analyzed the effects of scanning velocity and power on quenching depth and surface Rockwell hardness. The results showed that surface hardness slightly changed with received laser energy, while quenching depth remained consistent with scanning velocity. The maximum surface Rockwell hardness depends on the material, not laser power or scanning velocity. Decelerated laser quenching is more suitable for tooth surface machining due to the cumulative energy effect within the quenching depth range.

Summary: Extreme events in the past decades have led to an increase in drought-induced plant mortality globally. Timely information on plant water dynamics is crucial for understanding and predicting such mortality. Research has shown that using terrestrial laser scanning (TLS) intensity measurements can capture a significant portion of diurnal variation in leaf water potential (Psi(L)), enhancing our understanding of plant water dynamics.

Summary: Planar temperature images were obtained using laser Rayleigh scattering to determine temperature distribution in a constant volume combustion chamber. Burning velocities were measured from pressures and flame surface area from Rayleigh scattering images. The technique allows simultaneous measurement of temperature and burning velocity using a single-shot laser light.

Summary: This paper investigates the edge effect in the laser bending process of DP980 high-strength steel, finding that the edge effect intensifies with increasing laser scanning velocity. A varying velocity scanning strategy is proposed to reduce the edge effect. By comparing temperature distributions and bending angles under different scanning strategies, it is confirmed that the varying velocity scanning strategy can significantly reduce the edge effect and improve forming efficiency.

Summary: The study introduces a method for estimating Leaf Angle Distribution (LAD) in forest canopy structure and evaluates the impact of occlusion effect on LAD estimation. Results show that higher point density and increasing scanner height improve estimation accuracy. The study suggests that the occlusion effect, especially for taller trees, should be further examined in future research.

Summary: The study aimed to improve consumer perceptions of aquaculture products through the transmission of scientifically supported information. Results showed a slight but significant increase in consumer perception regardless of the communication tool used, with age and gender influencing perceptions the most. Consumption habits and knowledge about aquaculture were also key factors for changes in perception. This highlights the effectiveness of science- and fact-based communication campaigns in improving societal perception of aquaculture practices and products.

Summary: Recent developments in innovation policy have challenged the initial assumptions of Smart Specialisation Strategies (S3). The new S3, in response to the United Nations Agenda 2030 Sustainable Development Goals (SDGs), aims to address social and sustainable development challenges. This study proposes an extension of the reformed S3 approach to a multilevel governance setting, focusing on supporting innovation in the blue bioeconomy in the Mediterranean.

Summary: This study investigated the attitudes of secondary and university students in eight European countries towards including the concept of animal welfare in their educational programs. The results showed that female university students with high levels of subjective and objective knowledge on animal welfare and who supported more restrictive regulations were in favor of including the concept in their education. However, students who supported medical experiments on animals for human health improvement were less likely to accept animal welfare education. Additionally, students in Italy were more prone to supporting animal welfare educational programs compared to those in Sweden.
