Tapeworm Parasite Burden Is Linked to Diet, Body Size, Condition, Growth, Restocking and Habitat Use in Piscivorous Salmonids of a Subarctic Lake

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
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.

First Report on the Diet of the Angolan Flying Squid (Todarodes angolensis) in New Zealand Waters

New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
The Angolan flying squid (Todarodes angolensis) is a southerly distributed, large‐bodied ommastrephid preyed upon by many large marine vertebrates such as the southern elephant seal and deep‐sea squalid sharks. Here, we report its diet in New Zealand waters for the first time, identifying prey items from the stomach contents of 58 adults using ...

Age‐ and Growth‐Based Life‐History Traits of Striated Surgeonfish (Ctenochaetus striatus) and Achilles Tang (Acanthurus achilles) from Miti‘āro, Cook Islands

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
Striated surgeonfish (Ctenochaetus striatus) and Achilles tang (Acanthurus achilles) are two surgeonfish species commonly harvested for subsistence on Miti‘āro, Cook Islands. Using individuals collected by local fishers, this study provides the first age‐ and growth‐based assessment of these species from Miti‘āro.

Investigation of asymmetry in sagitta otolith features in relation to total length in Lethrinus species from the Red Sea coast of Yemen

Oceanological and Hydrobiological Studies
This study aimed to investigate the asymmetry in otolith length (OL), otolith width (OW) and otolith weight (OWe) in relation to total body length in 224 fish samples of Lethrinus borbonicus, L. letnjan and L.

Environmental effects on otolith morphology variability of European eel, Anguilla anguilla (Linnaeus, 1758), for subpopulation discrimination in Corsica

Frontiers in Marine Science
Otolith shape analysis is an efficient tool for fish stock identification. However, due to insufficient research, it remains still poorly understood concerning the European eel (Anguilla anguilla), a highly migratory catadromous and panmictic species ...

Impacts of Ocean Acidification on Reproduction and Early Life Development in Marine Teleost Fish—A Synthesis

Fish and Fisheries, Volume 27, Issue 5, Page 1176-1192, September 2026.
ABSTRACT Ocean acidification (OA) remains a major and underexplored threat to marine fishes, particularly regarding reproductive physiology and early life stages (ELS). Although research over the past 15 years has documented diverse OA effects, substantial knowledge gaps persist.

Otoliths in situ in Pinichthys shirvanensis Bannikov, 2021 (Stromateidae) from the Tarkhanian (Langhian, Middle Miocene) of the northern Caucasus (Russia)

Swiss Journal of Palaeontology
Otolith finds in situ are important for connecting the independent data sets of articulated fish skeletons and isolated otoliths in the fossil record. Here we describe an otolith in situ retrieved from a skeleton of the stromateid Pinichthys shirvanensis

Differences in sagittal otoliths between two morid species: insights into the genus Physiculus (Moridae: Gadiformes)

Neotropical Ichthyology
Sagittae are widely used as tools in taxonomic and ecological studies of fishes, especially when external morphological characters are conserved or ambiguous. We analyzed morphological variation between two congeneric species of Physiculus: P.

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

Fisheries Oceanography, Volume 35, Issue 5, Page 689-703, September 2026.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Interannual Variations in Distribution and Density of Japanese Anchovy (Engraulis japonicus) Larvae in the Shelf‐Break Region of East China Sea During Spring (2001–2022)

Fisheries Oceanography, Volume 35, Issue 5, Page 777-794, September 2026.
ABSTRACT Japanese anchovy (Engraulis japonicus) is the most abundant fish in the East China Sea (ECS) and an important fishery resource throughout its life stages. Using samples collected along the ECS shelf‐break in April over a 22‐year period (2001–2022), we examined the horizontal distribution and interannual variability of larval density (mean ...
