Do Coexisting Cryptic Species of Predatory Peacock Bass (Cichliformes: Cichlidae) Partition Their Niche?

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT The mechanisms facilitating coexistence of cryptic species in sympatry have long puzzled ecologists. Cryptic species have nearly identical morphology and, therefore, would be presumed to have high niche overlap and potential for interspecific competition and competitive exclusion when resources are limited. Lowland rivers in South America have

TOWARD EFFICIENT BYCATCH MANAGEMENT IN MULTISPECIES FISHERIES: A NONPARAMETRIC APPROACH

Linear programming-based models of individual multispecies groundfish operations in the Bering Sea/Aleutian Islands area are developed and applied to the question of determining efficient bycatches.

Assessing Risk for Bycatch and Byproduct Species Using a Modified Sustainability Assessment for Fishing Effects (SAFE) Approach

Fish and Fisheries, Volume 27, Issue 4, Page 831-849, July 2026.
ABSTRACT Central to ecosystem‐based fisheries management is ensuring the sustainability of bycatch and byproduct species. However, the sustainability of these species is difficult to assess as the lack of information limits the use of traditional stock assessment methods.

Using Stock Vulnerability to Evaluate Fishery‐Independent Survey Coverage and Inform Sampling Priorities

Fish and Fisheries, Volume 27, Issue 4, Page 912-926, July 2026.
ABSTRACT The consequences of mis‐managing vulnerable stocks (i.e., those with low productivity and high susceptibility to depletion) are high and potentially permanent. To support sustainable fisheries management, stock assessments can be improved by increasing the quantity and quality of fishery‐independent survey (i.e., survey) data.

Morphometric characteristics of Antarctic krill (Euphausia superba) and finfish bycatch in the krill fishery in the waters of South Orkney Islands during the 2022/23 fishing season

Frontiers in Marine Science
Determination of bar spacing of bycatch reduction devices (BRDs) should consider species composition and morphometric characteristics (particularly width) of target species krill and bycatch. This study conducted a scientific investigation of the finfish

Challenges and Opportunities for Strengthening Bottom‐Tow Fisheries Sustainability

Fish and Fisheries, Volume 27, Issue 4, Page 987-1005, July 2026.
ABSTRACT Bottom‐tow gear fisheries (trawls and dredges) produce ~24 million mt of harvest annually, representing a globally important animal‐sourced food system. While many are currently sustainably managed, growing concern over the potential for ecosystem impacts from bottom‐tow gears has increased pressure to improve these fisheries.

A half century of monitoring reveals contrasting survival responses of Icelandic seabirds to climate and fisheries pressures

Ibis, Volume 168, Issue 3, Page 950-971, July 2026.
Seabirds serve as key indicators of marine environmental changes, with adult survival being a critical parameter for assessing population health. Iceland hosts some of the largest seabird populations in the North Atlantic, making it a valuable location for studying long‐term trends in seabird demographics.

The influence of a cooling water system on waterbird habitat use in a coastal environment

Ibis, Volume 168, Issue 3, Page 1148-1158, July 2026.
This study investigated the impact of a cooling water system at a nuclear power plant in northern Europe on coastal waterbird habitat use. In winter, the cooling water system provided preferential areas for waterbirds with warm productive waters, and, more importantly, with ice‐free areas.

Radiographic Assessment of Bone Maturation: A Tool to Estimate Sexual Maturity in Common Dolphins (Delphinus delphis)?

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Accurate inference of sexual maturity is fundamental to interpreting marine mammal life histories and population structure. Using Bayesian logistic regression models with a hierarchical ordinal (HOF‐style) parameterisation and canonical analysis of principal coordinates (CAP), we evaluate skeletal metrics in the pectoral flippers of common ...

Pooled and Individual Bycatch Quotas: Exploring Tradeoffs Between Observer Coverage Levels, Bycatch Frequency, Pool Size, and the Precision of Bycatch Estimates

, 2000
The North Pacific Ocean is highly productive, hosting many of the world's largest groundfish populations and supporting a thriving fishing industry. Numerous regulations have been implemented to control the incidental take of non-target bycatch. Individual and Pooled Bycatch Quotas have recently been proposed as instruments that could further encourage
