ABSTRACT Human activities have significantly altered coastal ecosystems worldwide. The phenomenon of shifting baselines syndrome (SBS) complicates our understanding these changes, masking the true scale human impacts. This study investigates long‐term ecological effects anthropogenic on New Zealand's over 800 years using fish otolith microchemical profiling and dynamic time warping across an entire stock unit. Results reveal a shift in snapper ( Chrysophrys auratus ; Sparidae) habitat‐use...
Abstract Unveiling the intricate relationships between animal movement ecology, feeding behavior, and internal energy budgeting is crucial for a comprehensive understanding of ecosystem functioning, especially on coral reefs under significant anthropogenic stress. Here, herbivorous fishes play vital role as mediators algae growth recruitment. Our research examines preferences, bite rates, inter‐bite distances, foraging expenditure Brown surgeonfish ( Acanthurus nigrofuscus ) Yellowtail tang...
Investigating the dynamic interplay between energy storage and provisioning offers valuable insights into reproductive strategies. In this study we utilised fatty acids as proxy biomarkers to investigate energetic strategy of spawning Snapper (Chrysophrys auratus). Fatty acid profiles liver, ovaries, skeletal muscle showed significant variations in composition concentration. The liver was rich saturated (ΣSFA, 68.52%), ovaries were predominantly composed polyunsaturated (ΣPUFA, 43.44%),...
Abstract The inflow of terrestrial groundwater into the ocean is increasingly recognized as an important local source nutrients and pollutants to coastal ecosystems. Although there evidence a link between fresh submarine discharge (SGD)‐derived primary producer consumer abundances, effects SGD on productivity higher trophic levels such ichthyofaunal communities remain unclear. To further investigate this relationship, we sampled three sites inside coral reef lagoon in Mauritius: One site...
Fresh submarine groundwater discharge (fresh SGD), the efflux of terrestrial directly into ocean, is a ubiquitous pathway for nutrient-rich freshwater to coastal ecosystems, altering their hydrography, hydrochemistry, and primary productivity. Yet only little known about effects fresh SGD on fitness higher trophic levels such as teleost fish. Otolith analysis revealed that somatic growth rates were significantly settlement reef habitat took place earlier in juvenile grey demoiselle...
Anthropogenic factors have been identified as major stressors of nearshore environments such estuaries, sea grass meadows and mangroves. We hypothesize that aquatic organisms functionally dependent on these habitats nurseries respond to disturbances with subtle changes in their habitat-use patterns. used a novel approach coupling behavioural change point analysis fish otolith microchemistry analyse continuous life history information independent climate physiological variability. Here we...
Broodstock management has traditionally focused on heritable traits and diet-induced gamete quality. However, the potential of transgenerational plasticity (TP) underscores importance understanding adaptive trait transfer in aquaculture, where sustainability production can be hampered by mortality arising from disease stress. Notably, role fatty acids (FAs) as important biomarkers is an untapped area TP research with implications for new aquaculture species. We assessed Giant Kōkopu...

Abstract Behaviours of Clark's anemonefish Amphiprion clarkii and the dusky melanopus were studied in Vanuatu. Six anemones their resident fish observed for typical behaviours (hiding, watching, roaming, inter‐, intraspecific behaviour) with without presence a snorkelling observer. Observer had significant but contrasting effects on hiding behaviour A. . Bolder species may be able to outcompete other areas high human presence.
The ability of different broodstock generations to provision lipids their gametes is often overlooked in aquacultured freshwater fish. In this study we investigated the two (F1 & F2) Giant Kokopu (Galaxias argenteus) fatty acids into eggs. Here show that eggs captive-bred females (F2) displayed relative acid concentrations compared with bred from wild fish (F1). F2 generation showed significantly lower total mono unsaturated (MUFA) concentration, predominantly through C18:1(n−9) Oleic acid,...

Abstract In-depth understanding of animal movement ecology, including energy expenditure and internal budgeting, is crucial for deciphering the intricate dynamics ecosystem functioning. It essentially reveals resource partitioning flows among foraging organisms within their habitats. Ecosystems under severe anthropogenic stress, such as degraded coral reefs, serve valuable model habitats examining how patchy availability impacts behavior budgets herbivores. In this study, we employed...
Abstract Unveiling the intricate relationships between animal movement ecology, feeding behaviour, and internal energy budgeting is essential for a comprehensive understanding of ecosystem functioning. Particularly in degraded habitats like coral reefs, which are under significant anthropogenic stress, these interactions crucial yet largely unexplored. Employing advanced methods such as underwater stereo-video measurements, AI-driven object recognition, 3D tracking, our study focuses on...
