Early results and lessons learned from biomanipulation and chemical restoration of a eutrophic shallow lake

Restoration Ecology, EarlyView.
Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...

Applying multi-mesh gillnet to monitor fish communities in neotropical rivers

Neotropical Ichthyology
Neotropical fish diversity has been declining, driven by increasing human pressures. This accelerating loss underscores the urgent need for standardized methods capable of reliably monitoring these communities.

Tapeworm Parasite Burden Is Linked to Diet, Body Size, Condition, Growth, Restocking and Habitat Use in Piscivorous Salmonids of a Subarctic Lake

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Parasites affect hosts in interaction with the entire ecological community. This is particularly evident for trophically transmitted parasites, such as Dibothriocephalus tapeworms, which infect multiple intermediate fish hosts, potentially reducing their fitness and suitability for human consumption.

Integrating Acoustic Telemetry and Stable Isotope Data Reveals Overlap in Resource Use by Large‐Bodied Fishes in a Temperate Lake

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Temperate lake ecosystems undergo seasonal shifts that disproportionately alter the availability of suitable habitat for fishes of different thermal guilds. While many studies have investigated fish habitat use patterns, few have estimated the degree to which fish species overlap in space across seasons from a three‐dimensional perspective ...

Impacts of Ocean Warming on Sex Ratio of Yellow Striped Butterfish Labracoglossa argentiventris Around the Izu Islands, Japan

Fisheries Oceanography, Volume 35, Issue 5, Page 750-759, September 2026.
ABSTRACT Marine ecosystems are experiencing warming events in various regions of the world. Thus, many fish species and populations are now being impacted by the warmer water temperature conditions. Previous studies have reported temperature‐dependent sex determination (TSD) in various fish species.

Experimental study of ghost fishing by gillnets in Laguna Verde Valparaíso, Chile

Latin American Journal of Aquatic Research, 2014
In 2010, two experiments were carried out in order to study ghost fishing generated by lost or abandoned gillnets. The first experiment was aimed to identify and quantify the number of captured specimens in intentionally abandoned gillnet between 45 and ...

Variation in Life History Characteristics of Common Bream (Abramis brama) Populations in Sweden

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Knowledge of life history characteristics is important for fisheries management and monitoring of ecosystem integrity. This study examines life history characteristics of common bream (Abramis brama) from Swedish Baltic Sea coastal areas, two larger lakes and five smaller lakes in Sweden.

Response of the Diet Composition of Carassius auratus to Water Quality in Dianchi Lake, China

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Understanding the relationship between the diet composition of fish and water quality is significant for assessing fish responses to habitat changes. However, due to the complexity and diversity of both fish feeding and water quality, the relationship between the diet composition of fish and water quality is not fully understood to date.

Productivity of Bottom gillnet fishing gear on fish landing results at Fish Landing Base (PPI) Ujong Seurangga [PDF]

BIO Web of Conferences
The bottom gillnet is a passive fishing gear resembling a rectangle, designed with floats on the top and sinkers on the bottom. Evaluating the productivity of the bottom gillnets is crucial for assessing their effectiveness in catching fish.
