The gillnet fishery targeting Asian paddle crab (Charybdis japonica) is an important commercial fishery in the Yellow Sea of China. However, low catch rates represent a challenge, and solutions for improving the catch efficiency are crucial for economical sustainability in this fishery. Therefore, we tested whether the use of artificial fishing lights could improve gillnet catch performance. ...

Marine plastic pollution and continuous capture of marine animals, so-called “ghost fishing”, by abandoned, lost, or otherwise discarded fishing gear (ALDFG) are global concerns. This study investigated whether biodegradable polylactic acid (PLA) monofilaments can be used to replace conventionally used non-biodegradable polyamide (PA) in trammel net fishery for limiting ALDFG associated effects. It ...

This book is a followup, or a continuation rather, of the one I published in 2019 as part of the Too Big To Ignore (TBTI) Global Book Series, titled ‘Life Above Water: Essays on Human Experiences of Small-Scale Fisheries’. The design and purpose of the current book are the same. The introduction in the 2019 book could also work here, even if this book has a sharper focus on communities. Both consist ...

An image is what we have in our head and what we make up in an allegory, a name, a metaphor, a text, a map or in a drawing. None of these should be confused with the thing that is being imagined. They are not the real thing, just our imaginations of it. Still, we could not do without them, for instance when governing small-scale fisheries. They make us understand what we are up to and the track we ...

Fluorescence is routinely used to monitor kinase inhibition in commercial assays. Occasionally fluorescent compounds can interfere with the fluorescent reading. To address this issue, the problematic data are usually truncated to improve the fit, however, this approach raises ethical and reproducibility concerns. Instead, it is suggested to adjust the fitting formula, to account for the autofluorescence ...

Extreme climate events challenge the livelihoods of shrimp farmers worldwide. A comprehensive analysis of farmers’ choices of adaptive measures is essential for developing approaches that can lessen the effects of these climate risks. This study presents the determinants that influence the choice of adaptive measures in response to two climate risks, drought, and irregular weather, using a survey ...

Chlorella vulgaris is a freshwater microalga that synthesises large amounts of saturated lipids, which makes it suitable for production of bioenergy and biofuels. Since its cultivation usually requires freshwater, it competes with agriculture, economic development and ecological conservation for this limited natural resource. This study investigated the possibility of the partial replacement of ...

In the Barents Sea commercial snow crab (Chionoecetes opilio) fishery, an increase in catch efficiency of the conical pots is important for the profitability of the industry. Light emitting diodes (LEDs) have previously been tested for increasing catch efficiency of the snow crab pots. These earlier experiments have shown varying results ranging from large increase in snow crab catches to no ...

Agent-based models (ABMs) are increasingly utilized in ecology and related fields, yet concerns persist regarding the lack of consideration for lessons learned from previous models. This study explores the potential of systematically conducted ABM reviews to contribute to cumulative science and theory development by synthesizing individual ABM findings more effectively. We are conducting a meta-review ...

In order to improve the size selectivity and exploitation pattern for cocktail shrimp (Trachypenaeus curvirostris) in shrimp trawl fishery of the South China Sea (SCS), selective properties of four codends were tested and compared. These experimental codends involved two mesh sizes, 30 and 35 mm, and two mesh shapes, diamond-mesh (T0) and diamond-mesh turned by 90 degree (T90), respectively. Our ...
