Mystery of the Disappearing Dogfish: Transboundary Analyses Reveal Steep Population Declines Across the Northeast Pacific With Little Evidence for Regional Redistribution

Fish and Fisheries, Volume 27, Issue 1, Page 1-12, January 2026.
ABSTRACT Quantifying broad‐scale population trends and distribution change is critical for effective management and conservation of marine species, particularly under climate change. However, fragmented regional survey data often hinder such efforts for transboundary populations. A prime example is Pacific Spiny Dogfish (Squalus suckleyi, Squalidae), a

Comparative Morphology of Digestive Tract Among 11 Different Marine Fish Species

Aquaculture Research, Volume 2026, Issue 1, 2026.
Limited information is available about the digestive tract morphology and function in some marine fish species. Using anatomical methods, this study compared the morphological characteristics of the digestive tract among 11 marine fish species of different taxonomic status, feeding habits and ecological niches.

Use of Citizen Science to Determine Prey Partitioning Between Two Coastal Raptors

Ecology and Evolution, Volume 15, Issue 12, December 2025.
In Australia, Eastern Osprey (Pandion haliaetus cristatus) and White‐bellied Sea‐Eagle (Haliaeetus leucogaster) occupy the same ecological niche and are suspected of partitioning prey resources. This study investigated this through evaluating the breadth, overlap and partitioning of diets recorded from social media posts.

Measuring juvenile habitat quality for fishes and invertebrates

Biological Reviews, Volume 100, Issue 6, Page 2346-2395, December 2025.
ABSTRACT Identifying the role of marine and estuarine habitats in supporting fish and invertebrate populations during vulnerable juvenile life stages is essential to achieve effective conservation and fisheries management. There remains general agreement that: (i) the quality of juvenile habitat is best measured as the contribution of juveniles to ...

Controlled Ghost Fishing: Effects of Soaking Times and Mesh Sizes on Catchability in Trammel Net Fisheries

Fisheries Management and Ecology, Volume 32, Issue 6, Page 405-417, December 2025.
ABSTRACT Trammel nets are used with extended soaking times to increase the catching efficiency for demersal fish in commercial fishing. Long soaking time causes deterioration or damage to species caught in the first days. Effects of soaking time were investigated with 36‐mm, 42‐mm, and 46‐mm mesh sizes soaked over 1, 3, 5, and 7 days on target, non ...
