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.

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 ...

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.

Measuring management success for protected species: Looking beyond biological outcomes
The complexity of the ocean ecosystem, including the human component, is such that a single fishery may require multiple policy instruments to support recovery and conservation of protected species, in addition to those for fisheries management.

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

Assessment of Small‐Meshed Gillnets for Sustainable Fisheries in the Chobe River, Namibia
ABSTRACT Small‐meshed gillnets are restricted by the regulatory framework of the Namibian Inland Fisheries Act of 2003. This is mainly because smaller meshed nets are presumably selective towards juveniles of the large‐growing cichlid species. Thus, the aim of this study was to assess the impacts of smaller meshed gillnets (<73 mm) on the fish stocks ...
