Length‐Based Assessment of Hovsgol Grayling (Thymallus nigrescens), Lenok (Brachymystax lenok), and Burbot (Lota lota) Population Status in Lake Hovsgol, Mongolia Монголын Хөвсгөл нуурын Хөвсгөл хадран (Thymallus nigrescens), шөвгөр хоншоорт зэвэг (Brachymystax lenok), гутаарь (Lota lota) загасны уртад суурилсан популяцийн төлөв байдал

Fisheries Management and Ecology, Volume 32, Issue 2, April 2025.
ABSTRACT Despite the global importance of inland fisheries, data available for stock assessment is often limited. Data‐limited methods that use length composition data offer a potential approach to assessing more inland fisheries. We assessed the population status of three fish species in Lake Hovsgol, Mongolia through length‐based spawning potential ...

Freshwater Macroinvertebrate Community Responses to Drying Reflect Abiotic Stress, Frequency of Prior Drying and Proximity to a Perennial Reach

Freshwater Biology, Volume 70, Issue 4, April 2025.
ABSTRACT Intermittent streams dominate global river networks and are becoming increasingly common due to global change. Understanding the mechanisms by which freshwater biota respond to flow recession, drying, and intermittence is therefore important to our ability to support biodiversity as ecosystems adapt to ongoing stressors.

Minimal Introgression but Restricted Gene Flow: How Stocking and Dams Influence Wild Brook Trout (Salvelinus fontinalis) Genetics and Morphology

Freshwater Biology, Volume 70, Issue 4, April 2025.
ABSTRACT Anthropogenic activities are increasingly influencing eco‐evolutionary processes across spatial, temporal, and biological scales. Freshwater ecosystems, harbouring species that are important for subsistence, recreational, and commercial fisheries, are particularly vulnerable.

Effects of sex, family, and size grading on feed conversion ratio, growth, visceral fat, and weight loss in Delta Select channel catfish

Journal of the World Aquaculture Society, Volume 56, Issue 2, April 2025.
Abstract Feed conversion efficiency (FCE) is an important determinant of profitability in catfish production. Understanding factors affecting FCE at a physiological level could lead to improvement of FCE at production scale. The effect of sex, family, and size grading within family on juvenile channel catfish (Ictalurus punctatus) growth, feed ...

Corn‐fermented protein as a replacement for fish meal in diets for Atlantic salmon, Salmo salar, parr: Growth, feed utilization, antioxidant activity, non‐specific immune response, and gut histopathology

Journal of the World Aquaculture Society, Volume 56, Issue 2, April 2025.
Abstract Fishmeal (FM) is still believed to be the gold standard protein source, especially for high‐value aquaculture species such as salmon. However, due to supply and price fluctuations, coupled with environmental issues in FM production, FM is no longer a sustainable source from economic and environmental perspectives.

Inferring Species Interactions From Co‐occurrence Networks With Environmental DNA Metabarcoding Data in a Coastal Marine Food Web

Molecular Ecology, Volume 34, Issue 7, April 2025.
ABSTRACT A good understanding of biotic interactions is necessary to accurately predict the vulnerability of ecosystems to climate change. Recently, co‐occurrence networks built from environmental DNA (eDNA) metabarcoding data have arisen as a tool to explore interspecific interactions in ecological communities exposed to different human and ...
