MF23224Improving the size selectivity of crayfish fyke-net codend, applying the hexagonal mesh and sorting grid
Crayfish are important freshwater invertebrates both ecologically and economically. In Turkey, there is no aquaculture of this species, and it is solely produced through fishing. Owing to poor size selectivity of the fyke-nets used in harvesting this species, the rate of undersized catch is quite high (40.7%). This study aimed to enhance the size selectivity of fyke-nets through various manipulations.
MF23255Diel patterns of habitat use and movement by juvenile and subadult trout cod (Maccullochella macquariensis) in a regulated lowland river
This study investigated habitat use and movements of trout cod using radio-telemetry. Trout cod typically occupied small (<300 m) reaches of stream, undertook larger-scale movements and moved onto inundated riparian habitats during high flows. It occupied deeper water bank during the day and shallower water during the night and used areas with slower velocities more than was their availability. It also made extensive use of in-stream cover (i.e. wood). (Photograph by W. M. Koster.)
MF22192Evaluation and analysis of water-regulation value of ecosystem in Qinghai area of Qilian Mountain National Park, China
The InVEST water-yield model and support-vector regression (SVR) model were utilised to assess and forecast the ecosystem water-regulation value in Qinghai Area of Qilian Mountain National Park, China. The research showed that grassland plays a crucial role in regulating water, with an anticipated increase in both physical and monetary values by 2030. To further enhance monitoring efforts, it is recommended to establish an ecological big-data platform within the park.
MF23039Unravelling a specialised diet of an Amazonian catfish in a controlled flood-pulse area by combining stomach-content and stable-isotope analyses
Exploring what fish eat is important to understand how changes in the environment can affect their lives. In this study, we looked into the diet of an Amazonian catfish in a river affected by the construction of a dam. We found that the catfish mostly fed on sediment and aquatic insects, and these feeding habits were not strongly influenced by changes in the local water levels.
Lack of age data is a critical limitation in assessing the resource status of octopus. However, only a small number of researchers have the hands-on knowledge to execute these methods in the laboratory. Here, we present the first step-by-step guide to ageing octopus. We hope it will enable researchers new to ageing to undertake the process, as well as make an informed decision on the most suitable ageing method for their octopus species. (Photograph: E. D. Durante.)

MF23173Phenological and life-history responses of a tropical cladoceran Moina micrura to multiple environmental drivers
To explore climate effects on tiny aquatic life, we delved into how changes in water conditions affect Moina micrura, a small freshwater creature. Results showed that extreme pH harms the offspring and slows the heartbeat of this species, but warmth and longer daylight boost the numbers. Interestingly, M. micrura produces more males when food is scarce. This research informs strategies to protect these creatures in our tropical waters.
MF23161Immune responses of sea cucumber (Apostichopus japonicus) to combined environmental stress from high temperature and oil pollution
We investigated the immune responses in the respiratory tree of sea cucumber (Apostichopus japonicus) to high temperature, oil pollution, and the combined stress of high temperature and oil pollution. We found that acute exposure to oil pollution may have affect the immune function of sea cucumbers, whereas high temperature may exacerbate the health challenges of sea cucumbers subjected to environmental stress.
MF23236Genomic population structure of great hammerhead sharks (Sphyrna mokarran) across the Indo-Pacific
Currently, little information exists describing population structure of great hammerhead sharks (Sphyrna mokarran) in Australian waters. This study used genetic techniques to investigate structuring across the Indo-Pacific. No fine-scale population structuring was observed in Australia; however, structuring occurred for all Australian sharks when compared to those in the Red Sea. Findings suggest a single population for great hammerheads in Australia.

MF23116Gaps in gender reporting in National Reports of Convention on Wetlands of International Importance (2021–2022)
This perspective provides empirical data on the Ramsar Convention and gender equity. This paper assessed how Ramsar Convention complied with its own goals for gender mainstreaming in 2018, guided by the Global 2018 Gender and Wetlands Resolution agreed upon by 171 nations. The data were derived from National Reports from around the world. The findings shed light on the room for improvement in gender mainstreaming and gender equity in the wetland science and policy.
MF23094The social and economic dimensions of one of the world’s longest-operating shark fisheries
We calculated the social and economic contribution of the shark fishery operating in Western Australia, one of the world’s few sustainable shark fisheries. We found substantial management-driven reductions in fishing effort and improvement in catch rates. This fishery provides considerable socio-economic returns to regional economies, with an average annual market value of A$32.6 × 106.

MF23251Gill parasites of Schizocypris altidorsalis (Pisces: Cyprinidae), a threatened freshwater fish in Iran
Schizocypris altidorsalis is a freshwater fish only documented within a drying water reservoirs, on the border of Iran and Afghanistan. This study investigated the occurrence of highly host-specific monogenean parasites in this fish. A new species, Paradiplozoon jalalii, was found for the first time. Unless concerted efforts are initiated to restore their habitats, there is a significant risk of extinction for both species.

MF23175Environmental conditions on the Pacific halibut fishing grounds obtained from a decade of coastwide oceanographic monitoring, and the potential application of these data in stock analyses
Water-column profiler data, collected from 2009 to 2018 along the North American continental shelf, are synthesised to provide near-bottom oceanographic baseline information about the area, and to help identify environmentally distinct biological regions. A modelling method is presented as an example for exploring relationships between environmental variables and demersal fishes over space and time in the study area.

MF22278Biodiversity patterns of macrofauna associated with Halodule wrightii (Ascherson) in meadows of north-eastern Brazil
The macrofauna associated with Halodule wrightii meadows had a positive relationship between taxonomic and functional diversities, increasing from the least to the most complex habitats. The most prominent differences were in the composition of functional characteristics. We attribute the high macrofaunal diversity to a high species turnover among and within meadows, which synergises with shifts in environmental factors (e.g. organic-matter content). Our results suggest that the loss of complexity in Brazilian seagrass meadows results in changes in community composition and the ecological functions performed by the organisms.
MF23192Reproductive dynamics of striped marlin (Kajikia audax) in the central North Pacific
Striped marlin spawning in the central North Pacific was previously little studied. Our investigation has shown that both females and males mature at smaller sizes than in all other Pacific regions surveyed. These results have direct application for current efforts to evaluate the health and resilience of the population in the western and central North Pacific, which is currently considered to be commercially overfished and subject to continued overfishing.
