There are substantial knowledge gaps regarding both the bioacoustics and responses of animals to sounds associated with pre-construction, construction, operations offshore wind (OSW) energy development. A workgroup 2020 State Science Workshop on Wildlife Offshore Wind Energy identified studies for next five years help stakeholders better understand potential cumulative biological impacts sound vibration fishes aquatic invertebrates as OSW industry develops. The seven short-term priorities that include a mix primary research coordination efforts. Key needs examination animal displacement other behavioral sound, well hearing sensitivity related particle motion, substrate vibration, pressure. Other include: identification priority taxa which focus research; standardization methods; development long-term highly instrumented field site; mitigation options invertebrates. Effective assessment is currently precluded by these gaps. However, filling critical in will improve our understanding possible sound-related populations ecosystems.

How chronic anthropogenic noise can affect wildlife communities

Frontiers in Ecology and Evolution, Journal Year: 2023, Volume and Issue: 11

Published: April 5, 2023

Anthropogenic noise is a major pollutant in terrestrial and aquatic ecosystems. Since the industrial revolution, human activities have become increasingly noisy, leading to both acute chronic disturbance of wide variety animals. Chronic exposure can affect animals over their lifespan, changes species interactions likely altering communities. However, community-level impacts are not well-understood, which impairs our ability for effective mitigation. In this review, we address effects on communities explore possible mechanisms underlying these effects. The limited studies topic suggest that by changing behavior and/or physiology community, results direct or knock-on consequences other ecosystem. Major knowledge gaps remain due logistically complex financially expensive nature long-term needed questions. By identifying suggesting approaches answer them, provide road map toward mitigating noisy world.

Recent advances in acoustic technology for aquaculture: A review

Reviews in Aquaculture, Journal Year: 2023, Volume and Issue: 16(1), P. 357 - 381

Published: June 21, 2023

Abstract Acoustic technology has great application prospects in aquaculture. In particular, two indispensable, critical technologies for the future aquaculture industry are multi‐sensor acquisition that can achieve multi‐scale information fusion, collection and establishment of a global acoustic fish database highly developed deep learning intelligent algorithms establish correlation mechanism between behaviour characteristics. offers remarkable advantages large turbid water bodies studying spatial temporal distribution patterns aquatic organism populations, developing on‐demand feeding systems estimating biomass. This article reviews development its over last 30 years. It further analyses, detail, disadvantages evaluating biomass morphological physical indicators, welfare improvement. Challenges acquiring dynamic target data accurately, building establishing connections characteristics also discussed. brief, this aims to help researchers practitioners better understand current state‐of‐the‐art technologies, which provide strong support smart applications.

Through the advancement of observation systems, our vision has far extended its reach into world fishes, and how they interact with fishing gears—breaking through physical boundaries visually adapting to challenging conditions in marine environments. As sciences step era artificial intelligence (AI), deep learning models now provide tools for researchers process a large amount imagery data (i.e., image sequence, video) on fish behavior more time-efficient cost-effective manner. The latest AI detect categorize species are reaching human-like accuracy. Nevertheless, robust track movements situ under development primarily focused tropical species. Data accurately interpret interactions gears is still lacking, especially temperate fishes. At same time, this an essential selectivity studies advance integrate methods assessing effectiveness modified gears. We here conduct bibliometric analysis review recent advances applications automated tracking, classification, recognition, highlighting may ultimately help improve gear selectivity. further show transforming external stimuli that influence behavior, such as sensory cues background, interpretable features learn distinguish remains challenging. By presenting applied improvements (e.g., Long Short-Term Memory (LSTM), Generative Adversarial Network (GAN), coupled networks), we discuss advances, potential limits meet demands policies sustainable goals, scientists developers continue collaborate building database needed train models.

Fishes are exposed to natural and anthropogenic changes in their environment, which can have major effects on behaviour physiology, including feeding behaviour, food intake digestive processes. These alterations owing the direct action of environmental physico-chemical parameters (i.e. temperature, pH, turbidity) physiology but also be a consequence variations availability. Food is ultimately regulated by centres brain, receive process information from endocrine signals both brain peripheral tissues such as gastrointestinal tract. stimulate or inhibit intake, interact with each other maintain energy homeostasis.

Monitoring fisheries resources at offshore wind farms: BACI vs. BAG designs

ICES Journal of Marine Science, Journal Year: 2020, Volume and Issue: 77(3), P. 890 - 900

Published: Feb. 11, 2020

Abstract Offshore wind farms often co-occur with biodiverse marine ecosystems high ecological, economic, and cultural value. Yet there are many uncertainties about how affect organisms their environment. The before–after–control–impact (BACI) design, an approach that compares impact location unaffected control both before after the intervention, is most common method used to study offshore finfish. Unfortunately, this design has several methodological limitations undermine its ability detect effects in these studies. An alternative approach, before–after-gradient (BAG) would sample along a gradient increasing distance from turbines could overcome of BACI. BAG eliminate difficult task finding suitable control, allow for assessment spatial scale extent farm effects, improve statistical power by incorporating as independent variable analytical models rather than relegating it error term. This article explores strengths weaknesses BACI designs context development suggests into existing fisheries surveys regional monitoring framework.
