The Trout Paradox: Scenarios for Managing Introduced Salmonids in New Zealand

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
Introduced salmonids such as trout and salmon occupy a paradoxical position in New Zealand; celebrated as iconic sport fish yet condemned as invasive species that threaten native freshwater biodiversity. Motivated by an economic impact study of recreational fishing on Te Manahuna Mackenzie Basin hydro canals—the country's most popular salmonid fishery ...

Towards automated and real-time multi-object detection of anguilliform fishes from sonar data using YOLOv8 deep learning algorithm

Ecological Informatics
Freshwater eels (Anguilla spp.), including American eels (Anguilla rostrata), European eels (Anguilla anguilla), and Japanese eels (Anguilla japonica), are target species for conservation and of regulatory concern due to their vulnerability to various ...

Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

River Research and Applications, Volume 42, Issue 7, Page 1474-1499, September 2026.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, Volume 95, Issue 9, Page 1629-1641, September 2026.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Competitiveness in American Seafood Requires Climate‐Resilient Fisheries

Fish and Fisheries, Volume 27, Issue 5, Page 1234-1241, September 2026.
ABSTRACT Recent federal executive actions prioritize restoring American seafood competitiveness through deregulation and production targets, yet these policies overlook the fundamental threat posed by climate‐driven natural hazards. We argue that true seafood competitiveness cannot be achieved through production gains alone because competitiveness also

Population dynamics of the data-limited Indonesian shortfin eel (Anguilla bicolor) fisheries in the Greater Sunda Islands

Egyptian Journal of Aquatic Research
The high demand for eel capture production and aquaculture is dependent on wild-caught juvenile species, posing a significant risk of overfishing and population depletion.

Enabling Quantitative eDNA Monitoring in Lotic Ecosystems by Incorporating Hydrological Characteristics and Allometric Scaling

Freshwater Biology, Volume 71, Issue 9, September 2026.
ABSTRACT Effective freshwater biodiversity monitoring requires scalable methods to estimate fish abundance or biomass. Environmental DNA (eDNA)‐based approaches offer a promising alternative to observational methods. However, translating eDNA concentrations into reliable biomass estimates remains difficult in flowing waters because hydrological ...
