“…We used the following definition of EBFM as "managing fisheries to coordinate, account for, and include all factors in a holistic, synthetic, integrated fashion" (Link, 2010, p.23). Aspects of EBFM included, for example, considering the effects of fishing on non-target species, protected species, habitat, ecological interactions and system-wide processes (Link, 2010). We sub-sectioned the category "climate change adapta-…”

“…Therefore, achieving climate-adaptive fisheries needs an EBFM approach that considers climate change impacts both on ecosystems and on fish stocks within the overarching objectives of sustaining marine resource harvesting, species and habitat diversity, as well as ecosystem structure and functioning (Pikitch et al, 2004). Implementing EBFM means that a fishery is managed from a system perspective first, as opposed to a fisheries or stock perspective (Link, 2010) and encompasses multiple management tools to be implemented.…”

“…To implement climate-enhanced EBFM, climate-informed system-level indicators are paramount; these indicators can represent the very basis for reference points and EBFM management actions, such as ecosystem-based harvest limits or control rules (Link, 2010;Peterson Williams et al, 2021). An example of a system-level indicator for climate-informed tactical advice are indices for food-web production and function as they respond to climate change, such as size-specific biomass estimates, trophic dynamic indices and fish community mean length (Tam et al, 2017).…”

Climate change is considered a major threat to ocean ecosystems and human well-being (Blanchard et al., 2017; IPBES, 2019;Lotze et al., 2019). Changes in temperature, oxygen and other biogeochemical properties alter species distribution, growth, reproduction, abundance and trophic ecosystem structure (Cheung, Sarmiento, et al., 2013; IPCC, 2019). For example, many commercially important fishes and invertebrates are shifting their distribution towards polar, offshore or deeper waters to remain in their preferred thermal range . In addition, intensifying of marine heatwaves are affecting ecosystem structure and functioning (IPCC, 2019). Furthermore, due to the ongoing uptake of atmospheric CO 2 , the ocean is progressively acidifying (IPCC, 2019) which can be amplified by coastal upwelling (Feely et al., 2008), affecting cellular metabolism, organism physiology and ecosystem-level dynamics (Gattuso & Hansson, 2011).

“…Despite the implications for seafood health, the distribution patterns, transmissions, and epidemiology of zoonotic parasites in Indonesia remain largely unknown. As host migrations and marine food webs may change due to climate change (Palm et al 2011;Worm and Lotze 2021), this research area should be a focus of the investigation.…”

Metazoan endoparasite fauna and feeding ecology of commercial fishes from Java, Indonesia

et al. 2022

Despite being an important component of the marine ecosystem and posing health risks to human seafood consumers, fish parasites in Indonesia have yet to be adequately described. Here, we analyzed the diet and metazoan parasite fauna of seven commercial fish species (Alectis indica, Carangoides chrysophrys, Johnius borneensis, Mene maculata, Trichiurus lepturus, Upeneus asymmetricus, U. moluccensis) landed in Java, Indonesia. We isolated 11 endoparasite species, established 22 new host and 14 new locality records, and extended parasitological records of A. indica by 24%, C. chrysophrys by 25%, J. borneensis by 40%, M. maculata by 44%, U. asymmetricus by 100%, and U. moluccensis by 17%. We genetically identified the trematode Stephanostomum cf. uku (of Bray et al. 2005) from Alecta indica for the first time in Indonesia and provided the sequence of its 28S marker. Stomach content analysis revealed seven different prey items, and the examined fish species were grouped into four feeding categories, which differed significantly in their respective endoparasite fauna. All but two examined fish species hosted potentially zoonotic nematodes, which reveal a risk for parasite-borne diseases in Indonesian food fishes and call for more consequent monitoring with regard to seafood safety in this region. With this study, we were able to establish an association between the feeding ecology and the endoparasite fauna of marine fishes which will help to better understand the transmission pathways of (potentially zoonotic) parasites in food fishes in tropical waters.

“…Ecological communities and biodiversity are shaped by two main factors, climate change and invasive species (Mainka and Howard, 2010). With the currently ongoing climate change, many environments have already experienced alterations in their characteristics, and will continue to do so, while extremes increase in abundance and severity, consequently affecting ecological communities (Bellard et al, 2012;Mainka and Howard, 2010;Worm and Lotze, 2021). Invasive species play another important role in shaping ecological communities and biodiversity (Bax et al, 2003;Molnar et al, 2008).…”

The alternative oxidase (AOX) increases sulphide tolerance in the highly invasive marine invertebrateCiona intestinalis

Ecological communities and biodiversity are shaped by both abiotic and biotic factors. This is well illustrated by extreme environments and invasive species. Besides naturally occurring sulphide-rich environments, global change can lead to an increase in hydrogen sulphide episodes that threaten many multicellular organisms. With the increase in the formation, size, and abundance of oxygen minimum zones and hypoxic environments, bacterial-associated sulphide production is favoured and as such hydrogen sulphide-rich environments increase subsequently. Many species are challenged by the inhibiting effect of sulphide on aerobic energy production via cytochrome c oxidase, ultimately causing the death of the organism. Interestingly, many protist, yeast, plant, and also animal species possess a sulphide-resistant alternative oxidase (AOX). In this study, we investigated whether AOX is functionally involved in the sulphide stress response of the highly invasive marine tunicate, Ciona intestinalis. At the LC50, the sulphide-induced reduction of developmental success was three times stronger in AOX knock-down embryos than in control embryos. Further, AOX mRNA levels were higher under sulphide than control conditions - and this effect increased during embryonic development. Together, we found that AOX is indeed functionally involved in the sulphide tolerance of Ciona embryos, hence, very likely contributing to its invasive potential; and that the response of AOX to sulphide seems to be controlled at the transcriptional level. We suggest that AOX-possessing species play an important role in shaping marine ecological communities, and this importance may increase under ongoing global change.
