Climate-induced small pelagic fish blooms in an overexploited marine ecosystem of the South China Sea

Ecological Indicators, 2022
Marine ecosystems are a primary conservation concern because of the separate and synergistic effects of overfishing and climate change on their productivity and biodiversity.

Climate change and small pelagic fish price volatility [PDF]

Climatic Change, 2020
AbstractPrice volatility, an indicative measure of price uncertainty, is an important factor influencing fisheries cost, income, food security, and pressure on fish stocks. An increase in price volatility means that prices are varying more, making it more difficult to adjust the activities accordingly.

Growth Patterns of Small Pelagic Fish in West Africa [PDF]

Sustainability
Small pelagic fishes play important ecological roles in marine ecosystems, constitute some of the most economically valuable fisheries resources, and play a vital role in West African food security. Often living in upwelling regions, these species appear to have developed mechanisms to cope with environmental variability, such as opportunistic ...

Utilization of small pelagic fish species in Asia [PDF]

, 1996
This study sets out to define the current status of the utilization of small pelagic fish-fast growing species usually reaching maturity within a year-in Asia, and to assess competing demands on the resource so that appropriate strategies for the future development of the fishery can be determined.

Unclear associations between small pelagic fish and jellyfish in several major marine ecosystems. [PDF]

Sci Rep, 2019
During the last 20 years, a series of studies has suggested trends of increasing jellyfish (Cnidaria and Ctenophora) biomass in several major ecosystems worldwide. Some of these systems have been heavily fished, causing a decline among their historically

Zooplankton mortality effects on the plankton community of the northern Humboldt Current System: sensitivity of a regional biogeochemical model [PDF]

Biogeosciences, 2021
Small pelagic fish off the coast of Peru in the eastern tropical South Pacific (ETSP) support around 10 % of global fish catches. Their stocks fluctuate interannually due to environmental variability which can be exacerbated by fishing pressure.

Environmental DNA in the Kuroshio reveals environment-dependent distribution of economically important small pelagic fish

Frontiers in Marine Science, 2023
IntroductionSmall pelagic fishes constitute large proportions of fisheries and are important components linking lower and higher trophic levels in marine ecosystems.

Summer Biomass Variability and Spatial Interactions between European Sprat (Sprattus sprattus) and Moon Jellyfish (Aurelia aurita) in the Western Part of the Black Sea

Animals, 2023
Over the past few decades, various causal connections between commercial small pelagic fish species and gelatinous zooplankton have been reported in the Black Sea, which affect the pelagic ecosystem.

Effects of Lake Productivity on Density and Size Structure of Pelagic Fish Estimated by Means of Echosounding in 17 Lakes in Southeast Norway

Sensors, 2021
Density estimation of pelagic fish was performed by means of single beam echosounding in 17 lakes within a period of 34 years, from 1985 to 2018. Surveys were performed repeatedly (two to fourteen times) in five lakes.

Larval fish community composition and distribution of the central-southern Mediterranean under summer and winter conditions [PDF]

Acta Ichthyologica et Piscatoria, 2020
Background. The Gulf of Gabès supports an important fishery which is characterized by a great diversity of fish species. Despite this importance, there has been no attempt to examine the whole larval fish assemblage in this area.
