Sound produced by fish spawning aggregations (FSAs) permits the use of passive acoustic methods to identify timing and location spawning. However, difficulties in relating sound levels abundance have impeded acoustics conduct quantitative assessments biomass. Here we show that models measured production versus independently density can be generated estimate biomass from at FSAs. We compared Gulf Corvina (Cynoscion othonopterus) with simultaneous measurements active surveys Colorado River...
Group choruses of marine animals can produce extraordinarily loud sounds that markedly elevate levels the ambient soundscape. We investigated sound production in Gulf corvina ( Cynoscion othonopterus ), a soniferous fish with unique reproductive behaviour threatened by overfishing, to compare produced other animals. coupled echosounder and hydrophone surveys estimate magnitude aggregation during spawning. characterized individual calls documented changes soundscape generated presence as many...
In video-based fish surveys, species recognition plays a vital role in stock assessments, ecosystem analysis, production management, and protection of endangered species. However, implementing detection algorithms underwater environments presents significant challenges due to factors such as varying lighting conditions, water turbidity, the diverse appearances this work, transformer-enhanced YOLOv8 (YOLOv8-TF) is proposed for recognition. The YOLOv8-TF enhances performance by adjusting depth...
Reproductive behaviors and sound production of the Yellowfin grouper (Mycteroperca venenosa) are described from in-situ observations by divers as well synchronous underwater audio-video recordings at a spawning aggregation off Mona Island, Puerto Rico. The highest abundances M. venenosa estimated visual surveys were detected in March April, five to nine days after full moon (DAFM). Four distinct color phases observed for venenosa; two these unique one, white-headed phase, was exhibited...
Soundscapes offer rich descriptions of composite acoustic environments. Characterizing marine soundscapes simply through sound levels results in incomplete descriptions, limits the understanding unique features, and impedes meaningful comparisons. Sources that contribute to level metrics shift time space with changes biological patterns, physical forces, human activity. The presence a constant or chronic source is often interwoven episodic sounds. Further, intensity sources can influence...
Monitoring compliance and enforcing laws are integral to ensuring the success of marine protected areas (MPAs), but traditional monitoring techniques costly resource demanding. Three SoundTrap 300 recorders were deployed for one month between 1 July September 12, 2018 collect acoustic data in two parks off southeastern Australia: recorder Cod Grounds Marine Park (CGMP) Solitary Islands National Zone (SIMP NPZ). Extractive activities such as fishing not permitted these zones. Raven Pro 2.0...
Abstract Atlantic Cod Gadus morhua , which are overfished in the United States, potentially vulnerable to disturbance from offshore wind energy (OWE) construction and operation during their spawning period. While many aspects of biology well studied, little is known habitat use behavior at extreme southern extent species' range. As form dense aggregations produce sounds associated with courtship behaviors, we used a combination fixed‐station glider‐based passive acoustic monitoring methods...
Quantifying the number of recreational fishers is important for many aspects managing coastal resources. Unfortunately, quantifying boaters in offshore settings has proven difficult due to their distance from shore and a lack cost-effective methods monitor small boats (<10 m length). We investigated visitor-use at an marine protected area (MPA) southeastern USA. used multiple counting (satellites, buoy camera, passive acoustics, boat-based observations) generalized linear modeling approach...
Abstract Construction in the southern New England wind energy area (WEA), a large-scale offshore farm on east coast of United States, started June 2023. Baseline data was collected from 2020 to 2022, with six passive acoustic recorders (SoundTraps) deployed at shallow (&lt;60 m) sites vicinity Nantucket Shoals and Cox’s Ledge. Data were analysed for sperm whale presence, demographic composition assessed using interclick intervals. Presence varied by site, season, year. Sperm whales...
Abstract Co‐operation in the management of shared fish stocks is often necessary to achieve sustainability and reduce uncertainty. The United States America (USA) Mexico share a number marine ecosystems, while there some binational co‐operation scientific research, unilateral decisions are generally rule. We present case study using giant sea bass ( Stereolepis gigas , Polyprionidae) highlight how these research asymmetries can skew national perceptions population status for fully...
The reproductive and acoustic behaviours of Gulf grouper Mycteroperca jordani were studied at a spawning aggregation site in the southern California, México. In May 2015–2017, divers located surveyed within Cabo Pulmo National Park. Adult M. conformed to lek mating system which large males formed territories over sand adjacent rocky reef that spatially segregated from smaller females outside courtship periods. Females moved into male during evening hours spawn. Male targeted single female,...
ABSTRACT The hemlock woolly adelgid invasion is expected to cause widespread mortality of eastern (Tsuga canadensis) throughout much New England. Light levels in streams with riparian zones are anticipated increase as trees replaced by deciduous trees. We sought to: (1) quantify differences light reaching and zones, (2) determine if increases result higher periphyton biomass, (3) explore the role macroinvertebrate grazing on biomass an attempt help predict stream ecosystem responses...
Soundscapes represent an intrinsic aspect of a habitat which, particularly in protected areas, should be monitored and managed to mitigate human impacts. Soundscape ecology characterizes acoustic interactions within environment, integrating biological, anthropogenic, climatological, geological sound sources. Monitoring soundscapes marine areas is important due the reliance many species on for biological functions, including communication reproduction. In this study we establish baseline...
This study identified a new sound produced by Nassau Grouper in association with, although potentially not exclusive to, an agonistic interaction at spawning aggregation. We have also provided behavioral and acoustic description for identification of this future studies. The discovery third type further highlights the importance communication coupled with visual displays fishes. Furthermore, increases ability to document presence endangered species sites. Future efforts may reveal that is...
Abstract While monitoring fish sounds has enhanced our understanding of spatio-temporal patterns spawning and acoustic communication, data interpretation often fails to account for environmental effects on recordings, resulting in uncertainty whether measures detected correspond rates sound production, specific behaviours, abundance. In this study, we applied propagation modelling detection theory estimate production territorial, male Gulf grouper (Mycteroperca jordani) from passive...
The United States of America’s Office National Marine Sanctuaries (ONMS) hosts 15 (NMS) and two Monuments in its waters. Charismatic marine megafauna, such as fin whales ( Balaenoptera physalus ), humpback Megaptera novaeangliae various delphinid species frequent these areas, but little is known about their occupancy. As part a national effort to better understand the soundscapes NMS, 22 near-continuous passive acoustic bottom mounted recorders one bottom-mounted cable hydrophone were...
Abstract Protected areas are typically managed as a network of sites exposed to varying anthropogenic conditions. Managing these networks benefits from monitoring conditions across help prioritize coordinated efforts. Monitoring marine vessel activity and related underwater radiated noise impacts protected areas, like the U.S. National Marine Sanctuary system, helps managers ensure quality habitats used by wide range species. Here, we use acoustic detections vessels quantify different...
Passive acoustic monitoring (PAM) data collection has been growing exponentially, resulting in petabytes of that document ocean soundscapes, how they change over time, and what animals use these ecosystems at varying timescales. Efficiently extracting this critical information comparing it to other datasets the context ecosystem-based management is a Big Data challenge traditional desktop processing methods cannot address. The curation, management, dissemination PAM another need...
