ABSTRACT Changing ocean conditions driven by anthropogenic activities may have a negative impact on fisheries by increasing stress and disease. To understand how environment and host biology drives mucosal microbiomes in a marine fish, we surveyed five body sites (gill, skin, digesta, gastrointestinal ...
Globally, our knowledge on lake fisheries is still limited despite their importance to food security and livelihoods. Here we show that fish catches can respond either positively or negatively to climate and land-use changes, by analyzing time-series data (1970–2014) for 31 lakes across five continents. ...
The invention aims at a method for cultivating chimeric macroalgae, especially brown algae, where chimeric individuals are obtained in the laboratory and subsequently transferred to their definitive habitat. Chimeric macroalgae have advantages in their growth rate and greater resistance to environmental ...
A multi-sensor system (300) for monitoring water parameters, the system including a first metallic layer (324); a dielectric layer (326) formed on the first metallic layer (324); a second metallic layer (330) formed on the dielectric layer (326); a power source (314) electrically connected to the second ...
Alongside government driven management initiatives to achieve sustainable fisheries management, there remains a role for market-based mechanisms to improve fisheries outcomes. Market-based mechanisms are intended to create positive economic incentives that improve the status and management of fisheries. ...
There is provided a fish egg processing apparatus capable of performing a predetermined processing on fertilized eggs with higher efficiency. A gene injection device 1 which is a fish egg processing apparatus according to the present invention includes a processing water tank 8 which processes collected ...
The present disclosure discloses a method of using an unmanned aerial vehicle (UAV) comprising a housing, a processor, a positioning unit, a sonar unit, a launching unit and a fishhook unit in fishing. The method comprises manipulating the UAV to fly to a designated destination determined by the processor ...
Chitosan oligosaccharide (COS) has become of great interest in recent years because of its worthy biological activities. This study aims to produce COS using the enzymatic method, and investigates Paenibacillus sp. TKU047, a chitinolytic-producing strain, in terms of its chitosanase productivity on ...
Resistance to stainless steel corrosion in marine-based industries requires more research into materials with an improved surface and enhanced protection by utilizing surface coatings. Herein, a thermally stable aramid–zirconia nanocomposite has been successfully prepared using the sol–gel method to ...
Spatial conservation prioritization is used worldwide for designing marine protected areas (MPA) that achieve set conservation objectives with minimal impacts to marine users. People involved in small-scale fisheries (SSF) may incur negative and disproportionate impacts from implementing MPAs, yet limited ...
Background Epidemiological studies suggested that determinants for antibiotic resistance have originated in aquaculture. Recently, the integrated agriculture-aquaculture system has been implemented, where fish are raised in ponds that receive agriculture drainage water. The present study aims to investigate ...
Abstract Recent droughts raise global concern over potential biodiversity loss and mitigating impacts to vulnerable species has become a management priority. However, drought impacts on populations are difficult to predict, in part, because habitat refuges can buffer organisms from harsh environmental ...
Wetland ecosystems have been globally degraded and lost due to rapid urbanization and climate change. An assessment of national scale inventory, including wetland types and conditions, is urgently required to understand the big picture of endangered wetlands, such as where they are and how they look ...
The corallivorous Crown-of-Thorns Starfish (CoTS, Acanthaster spp.) has been linked with the widespread loss of scleractinian coral cover on Indo-Pacific reefs during periodic population outbreaks. Here, we re-examine CoTS consumption by coral reef fish species by using new DNA technologies to detect ...
Invasive species present a major conservation threat globally and nowhere are their affects more pronounced than in island ecosystems. Determining how native island populations respond demographically to invasive species can provide information to mitigate the negative effects of invasive species. Using ...
Abstract For Pacific salmon, the key fisheries management goal in British Columbia (BC) is to maintain and restore healthy and diverse Pacific salmon populations, making conservation of salmon biodiversity the highest priority for resource management decision‐making. Salmon status assessments are often ...
Simple Summary Thick-lipped grey mullet (Chelon labrosus) feeds on the lowest trophic levels during adult stages, for which it is considered a viable candidate for an economically and environmentally sustainable aquaculture. Similar to most of marine fish species, C. labrosus produce a large number ...
A dataset is presented of an experiment that was conducted to compare the proportions of males obtained from hormonal sex reversed pure strain of Oreochromis shiranus and from interspecific hybridization of O.karongae male x O. shiranus female. Part of the data in the dataset were published in a journal ...
Abstract Understanding the stress responses of sharks to recreational catch and release fishing has important management and conservation implications. The blacktip shark Carcharhinus limbatus is a popular recreational species targeted throughout the western, central and eastern Gulf of Mexico (Gulf) ...
Abstract For Pacific salmon captured and released by fisheries, post-release behaviour and survival may be influenced by their health and condition at time of capture. We sought to characterize the interactions between infectious agent burden, fish immune and stress physiology and fisheries stressors ...
