Summary: Aquatic ecosystems are affected by human activities, leading to a loss of biodiversity. Ocean sound, particularly fish sounds, has been used to study communication, behavior, and biodiversity. Artificial intelligence, specifically machine learning, can be used to detect and classify fish sounds, but the lack of validated sound data for individual species is a challenge. This review examines recent publications on the use of machine learning for fish sound analysis, highlighting key challenges and suggesting directions for future research.

Summary: The use of passive acoustic monitoring in wildlife ecology has increased, with researchers successfully applying deep learning techniques to automate the detection of forest-adapted birds and mammals. By integrating a deep convolutional neural network into a multi-step workflow, researchers can efficiently process large volumes of audio data, significantly reducing human effort. Additionally, a graphical interface for the neural network has been developed to provide field biologists and managers with a portable and user-friendly tool for processing audio data and detecting target species in real-time.

Summary: The uncontrolled colonization of benthic organisms on submerged surfaces, known as biofouling, causes damage in the shipping and aquaculture industries. Recent studies show that ship sounds enhance the larval settlement and growth of invertebrate species associated with biofouling. This study assesses the impact of anthropogenic sounds, such as pile driving, drilling, and vessel sounds, on the development of biofilms and larvae of model species associated with micro and macrofouling. The results indicate that the drilling sound has a strong effect on the biofilm thickness and significantly reduces the settlement and clearance rate of mussel larvae.

Summary: Snapping shrimp are widely distributed in coastal waters and produce strong pulses that can serve as honest signals indicating specific habitat soundscape. The acoustical activity of snapping shrimp has been increasingly studied in shallow waters, including the west Pacific Ocean and Southeast China coastal area. Analysis of recorded snaps revealed that they were louder than background noise, with a sound pressure level ranging from 150 dB to 190 dB. The snaps exhibited consistent characteristics across different sites, with peak frequencies below 10 kHz but considerable energy extending to frequencies over 200 kHz. The analysis of acoustic data also showed a correlation between snap rate and tidal level periodicity, with a higher snap rate at night. These findings deepen our understanding of the snapping behavior of shrimp and its relationship with ecological environments.

Summary: This study conducted surveys of the mesophotic reef in the Au'au Channel between Maui and Lana'i islands using various methods. The results showed that depth, benthic substrates, and coverage have an impact on the distribution of fish assemblages in the mesophotic reef. Additionally, two distinct mesophotic assemblages were identified, one in the upper depths and the other in the lower depths.

Summary: The study found that different types of coral reef structures have varying effects on fish assemblages, with the ecological patterns of artificial reef ecosystems still poorly understood. Therefore, management strategies need to be tailored to specific site or reef goals and needs to improve the effectiveness of management actions on reef restoration and artificial reef habitats.

Summary: The study evaluated the performance of two models of GoPro underwater action cameras as PAM recorders, finding that they can reliably capture underwater acoustic recordings. Although not directly comparable with hydrophone-derived values, metrics derived from GoPros can be valuably compared between recordings taken using the same model.

Summary: Marine crustaceans produce broadband sounds that cannot be accurately characterized in tanks, as demonstrated by a comparison between tank and in situ recordings of spiny lobsters. The study highlights the significant differences in temporal, power, and spectral features of the sounds produced in tanks and in natural conditions. Tank physical impacts, including resonant frequencies, sound reverberation, and low frequency attenuation, are identified as major factors distorting broadband crustacean sounds. Understanding these physical impacts is crucial for accurately characterizing marine crustacean sounds.

Summary: This study investigated the contamination of microplastics (MPs) in four coastal fish species from the southwestern Tropical Atlantic. All species analyzed were found to be contaminated with MPs, with Alphestes afer being the most contaminated. There were no significant differences in the number and size of particles detected among species, and the most common shapes were fibers and films, with polyethylene being the most abundant polymer. This study provides important baseline data on MP contamination in coastal fish species, which is relevant for conserving marine biodiversity.

Summary: The degradation of coral reefs worldwide has led to significant investments in their active restoration. Research shows that restoration efforts not only help increase coral cover but also play a vital role in restoring the soundscape of the reef ecosystem, which is essential for the recruitment of reef organisms. Passive acoustic monitoring (PAM) could be a valuable tool for evaluating ecosystem-level recovery, but caution is needed when choosing metrics and interpreting results as different PAM metrics may reflect different aspects of the reef soundscape.

Summary: Hypostomus is a diverse genus within Loricariidae, but differentiating species within this genus can be challenging due to their conservative morphology. This study investigates the sound production of ten species from Brazil and explores whether acoustic features can be used to distinguish between these species. The findings suggest that acoustic features and dorsal spine characteristics are not reliable identifiers for these species. The sounds produced by these fish may serve as an alarm or acoustic aposematism signal rather than for conspecific recognition in reproduction.

Summary: Three-dimensional shallow benthic complexity provides valuable information for coral reef conservation and management, as it reflects the physical conditions and biodiversity of shallow coral reef environments. This study mapped global shallow water benthic complexity using satellite images and found that high complexity regions are mainly concentrated in areas with high benthic biodiversity. However, a significant portion of coral reef regions with high benthic complexity remains unprotected. The global coral reef benthic complexity map generated in this study can contribute to improving marine protected areas, reef conservation, and management.

Summary: The sinking of artificial structures may enhance the co-occurrence of rare species, but they do not generate the beta diversity patterns observed in natural reefs. While artificial habitats contain a significant portion of regional reef fish diversity, they may also have contributed to the degradation of nearby natural reefs.

Summary: Damselfishes in Brazil's tropical and subtropical coastal systems are mainly influenced by wave exposure and depth, with weak associations to benthic cover. Stegastes fuscus prefers shallow and sheltered reefs, while Stegastes variabilis inhabits shallow habitats with higher exposure. There is a consistency in habitat requirements for Brazilian damsels in both tropical and subtropical reefs. Long-term monitoring is needed to understand how these species will respond to global changes and human impacts.
