The collective dynamics of self-organised systems emerge from the decision rules agents use to respond to each other and to external forces. This is evident in groups of animals under attack from predators, where understanding collective escape patterns requires evaluating the risks and rewards associated with particular social rules, prey escape b...

Fish diversity, an important indicator of aquatic ecosystem health, is declining due to water pollution, overfishing, climate change, and invasive species. Effective surveying and monitoring are required to protect fish diversity. Here, a high-sensitivity environmental DNA (eDNA) metabarcoding technique was used to investigate fish diversity in the...

The objective of this opinion was to determine if any wild caught fish species, originating from specific fishing grounds and consumed in the EU/EFTA could be considered free of zoonotic parasites. In this Opinion the term ‘fishery products’ only refers to fresh finfish. As there are multiple fish species and numerous potential parasites, Anisakis...

We evaluate the effects of rebuilding a mackerel fishery in Korea using a bioeconomic computable general equilibrium (CGE) model. The effects include three different measures of the benefits of the stock rebuilding-the fishing sector's rent, its value-added, and the aggregate regional welfare. In the baseline simulation, we run 20 scenarios over 30...

Glycinin, a major anti‐nutrient in soybean meal, may trigger enteritis and oxidative stress in fish with overconsumption. However, its impact on intestinal inflammation and underlying signaling mechanisms in Larimichthys crocea remains unclear. The purpose of this study was to assess the effects of glycinin on growth, antioxidant function, inflamma...

Enneapterygius pallidoserialis Fricke, 1997, previously considered a valid species, is regarded as a junior synonym of E. erythrosoma Shen, 1994. Re-examination of type specimens of both nominal species revealed that the meristic and morphometric characters of the holotype and seven paratypes of E. pallidoserialis examined closely matched those of...

The epinephelid longtooth grouper comprises two nominal species, Epinephelus bruneus Bloch, 1793 and E. moara (Temminck and Schlegel, 1843). The name E. moara had been applied to specimens in Japan, Taiwan, and South Korea, but was later relegated to the junior synonymy of E. bruneus. However, in continental China, two forms of longtooth groupers h...

The problem of marine noise pollution has a long history. Strong noise (>120 dB re 1 µPa) will affects the growth, development, physiological responses, and behaviors of fish, and also can induce the stress response, posing a mortal threat. Although many studies have reported that underwater noise may affect the survival of fish by disturbing their...

In recent decades, China’s large-scale stock enhancement programs to restore the collapsing large yellow croaker (Larimichthys crocea) fishery resources have not yielded the desired results, and a comprehensive analysis of the underlying reasons for this problem is required. Based on small yellow croaker (Larimichthys polyactis) catch survey data o...

Phosphatidylethanolamine (PE) is a ubiquitous bioactive lipid in cells, which participates in regulating many metabolic processes.

The mean weight-at-age of fish species is an indicator of fish growth and physiological condition, as well as a basic parameter for assessing and managing fish stocks. Here, we investigate the temporal trends of the mean weight-at-age of four different commercial species with different life strategies: (i) the short-lived pelagic European sardine (...

In traditional folk taxonomy, various fish species have been categorised in accordance with the social structures and kinship systems of human beings. According to this world-view, it was natural that the eel (Anguilla anguilla) had an Eel-Mother, who was responsible for reproduction, and that the eel was regarded as a relatíve to the snakes and wa...
