“…However, despite the content-rich description of these analyses, few studies have approached the effects of LoF in fish. Behavioral cascades and patterns of risk aversion have been documented in coral reef fishes (57–59) and juvenile salmonids (60). In a highly simplified model of predator-prey relationship between trout ( Oncorhynchus.…”

Netting the Stress Responses in Fish

In the last decade, the concept of animal stress has been stressed thin to accommodate the effects of short-term changes in cell and tissue physiology, major behavioral syndromes in individuals and ecological disturbances in populations. Seyle's definition of stress as “the nonspecific (common) result of any demand upon the body” now encompasses homeostasis in a broader sense, including all the hierarchical levels in a networked biological system. The heterogeneity of stress responses thus varies within individuals, and stressors become multimodal in terms of typology, source and effects, as well as the responses that each individual elicits to cope with the disturbance. In fish, the time course of changes after stress strongly depends on several factors, including the stressful experiences in early life, the vertical transmission of stressful-prone phenotypes, the degree of individual phenotypic plasticity, the robustness and variety of the epigenetic network related to environmentally induced changes, and the intrinsic behavioral responses (individuality/personality) of each individual. The hierarchical heterogeneity of stress responses demands a code that may decrypt and simplify the analysis of both proximate and evolutionary causes of a particular stress phenotype. We propose an analytical framework, the stressotope , defined as an adaptive scenario dominated by common environmental selective pressures that elicit common multilevel acute stress-induced responses and produce a measurable allostatic load in the organism. The stressotope may constitute a blueprint of embedded interactions between stress-related variations in cell states, molecular mediators and systemic networks, a map of circuits that reflect the inherited and acquired stress responses in an ever-changing, microorganismal-loaded medium. Several features of the proposed model are discussed as a starting point to pin down the maximum common stress responses across immune-neuroendocrine relevant physiological levels and scenarios, including the characterization of behavioral responses, in fish.

“…After the loss of coral cover, the densities of herbivores increased significantly (Ruppert, Travers, Smith, et al, 2013). The increase of herbivorous fish can be related to higher food availability (Adam, Schmitt, Holbrook, et al, 2011;Fong, Frias, Goody, et al, 2018) and might be expected the abundance of algae trigger herbivorous fishes to grow following an extensive coral loss (Jayewardene, 2009). The hypothesis confirms the role and importance of herbivorous reef fishes in maintaining coral reef resilience and avoiding coral-algal phase-shifts (Bellwood, Hughes, Folke, et al, 2004;Hughes, Baird, Bellwood, et al, 2003;Hughes, Rodrigues, Bellwood, et al, 2007).…”

“…Understanding algal succession and the influence of herbivorous fishes is central to the development of knowledge about how coral reef ecosystems may respond to and recover from increasing anthropogenic pressures (Burkepile & Hay, 2010;Ceccarelli, Jones & McCook, 2011). The herbivorous fishes have been considered as a critical functional group and have capability maintaining coral reef resilience and avoiding coral-algal phase-shifts (Bellwood et al, 2004;Dromard, Bouchon-Navaro, Harmelin-Vivien, et al, 2015;Fong et al, 2018;Hughes et al, 2003Hughes et al, , 2007. The strong functional group of herbivorous fish may maintain the coral reef and remove algal states (Fong et al, 2018), with consuming primary benthic algae and regulate competition between algae and reef-building corals (Edwards, Friedlander, Green, et al, 2013;Wilson, Bellwood, Choat, et al, 2003).…”

The herbivorous fishes have been considered as a critical functional group and have capability maintaining coral reef resilience and avoiding coral-algal phase-shifts. The present condition shown, almost in tropical reef location, alga has dominated coral, even in the small outer island. The requirement to conduct comprehensive basic research in studying the patterns and composition of herbivorous fish, especially on the small outer islands. Twelve coral reef sites in eastern Indonesia (Liki Islands) and western Indonesia (Natuna Island) used as a research location for comparing the structure patterns of herbivorous fish communities (diversity, density, and body size) using the Underwater Visual Census (UVC) method. There was different pattern of herbivorous fishes families in Liki Island and Natuna Islands, where Acanthuridae is dominant in eastern Indonesia (Liki Islands), including Ctenochaetus striatus (41,00 ± 11,72 se) individuals/350m2, A. maculiceps (23,33 ± 13,61 se) individuals/350m2, Naso hexacanthus (18,67 ± 6,34 se) individuals/350m2 while Scaridae is dominant in western Indonesia (Natuna island), including Scarus rivulatus (31,67 ± 10,61 se) individuals/350m2, Chlorurus sordidus (30,00 ± 8,52 se) individuals/350m2 and Scarus quoyi (19,00 ± 9,73 se) individuals/350m2. Based on herbivore fishes composition Liki Island has a higher density and biomass compared to Natuna Island.Keywords: herbivore, fish, coral, small outer island, Indonesia

“…Menurut Pombo-Ayora et al (2020) dan Fong et al (2018) tingginya kelompok herbivor dapat menstabilkan biomassa alga yang tumbuh di karang dan dapat membantu memfasilitasi kelangsungan hidup dan pertumbuhan karang, yang pada gilirannya dapat mendorong pemulihan karang. Menurut Rahmadani (2020), Pulau Pasumpahan mengalami kerusakan ekosistem yang cukup memprihatinkan karena terjadi nya penurunan tutupan karang, kondisi terumbu karang hidup di Pulau Pasumpahan di golongkan buruk, kondisi ini disebabkan karena faktor manusia yang merusak biota di Pulau Pasumpahan.…”

The territorial waters of Pasumpahan Island contain tourism and fishing activities which are assumed to affect the coral reef ecosystem and reef fish communities in the area. Monitoring the development of coral reef fish resources is an important approach to detect changes. This study aims to analyze the abundance, the diversity and the biomass of reef fish in the waters of Pasumpahan Island, Padang City. This research was conducted in March 2022 in 5 (five) different research locations with The Underwater Visual Census (UVC) as the data collection method. The units of analysis in monitoring changes are 7 families of carnivorous and herbivorous reef fish, such as Serranidae, Lutjanidae, Lethrinidae, Haemulidae, Acanthuridae, Scaridae, Siganidae and 1 obligate coral tribe (Chaetodontidae). The results of this study indicated that the highest abundance of reef fish found came from the herbivore group with an abundance value of 3,171 individuals/hectare at station 3, the highest abundance of Corallivor groups was found at station 2 with an abundance value of 1,171 individuals/hectare and the highest abundance of carnivore groups was found at station 2 with an abundance value of 171 individuals/hectare. The diversity of reef fish found at the study site is in the low category with an H' value <2.30. Meanwhile, the biomass of reef fish in the waters of Pasumpahan Island is in the low category with a biomass value of <300 kg/hectare.
