José Paitio et al.
Neoscopelus is a genus of deep-sea fishes with ventral-lateral photophores, likely used for counterillumination. In this study, we report a novel functional structure of spectral filter in the bioluminescence mechanism of Neoscopelus microc...
Cause or consequence? Exploring authors' interpretations of correlations between fish body condition and parasite infection [0.03%]
因果关系吗？探索作者对鱼类体况与寄生虫感染相关性解释的解读

Identifying critical habitats is important for the effective management of vulnerable species. Critical habitats, such as mating or nursery grounds, support populations during key life stages and help to maximise reproductive output and pop...
Two's company: Monozygotic twinning in the small-spotted catshark (Scyliorhinus canicula) [0.03%]
双倍的快乐：小斑猫鲨（Scyliorhinus canicula）中的同卵双胞胎现象
Andrej A Gajić,Emilie de Loose,Andrea G Martin et al.
Andrej A Gajić et al.
Developmental abnormalities in elasmobranchs (sharks and rays) are rarely documented, with reported cases primarily involving fin or cranial deformities. Monozygotic twinning, the formation of identical twins from a single zygote, is partic...
Speed-dependent locomotor patterns during steady swimming in a demersal shark [0.03%]

Swimming ability is critical for navigating complex benthic habitats, yet the biomechanical strategies demersal sharks employ to modulate body and fin movements across varying speeds remain largely unexplored. This study examines speed-depe...
Group swimming significantly decreases time to passage success for a galaxiid species [0.03%]
群游显著减少鱼类通过时间以获得成功率

Rachel M B Crawford et al.
We conducted laboratory experiments to explore the potential benefits of group behaviour on passage performance for a small-bodied migratory species, inanga Galaxias maculatus. An artificial velocity barrier was created to compare the fish ...
Molecular genetic assessments of the ongoing restocking activities on Salmo caspius Kessler, 1877 [0.03%]

Arezo Najafikhah et al.
Maintenance of genetic diversity in broodstocks is highly important for restocking and aquaculture activities. Salmo caspius, a native species in the southern basin of the Caspian Sea, is a commercially important species, yet wild populatio...
Migratory patterns and seasonal habitat use of great hammerhead sharks (Sphyrna mokarran) in the southeastern United States [0.03%]
美国东南部迁徙的大虎鲨（Sphyrna mokarran）的迁移模式和季节性生境使用情况

Grace A Casselberry et al.
The great hammerhead shark (Sphyrna mokarran) is a highly mobile shark species whose population in the United States declined dramatically through the early 2000s. Their spatial ecology is poorly understood, creating challenges for effectiv...
European seabass, Dicentrarchus labrax, show no significant response to infrared light [0.03%]
欧洲海鲈鱼（Dicentrarchus labrax）对红外光没有显著反应
Alexa Sugpatan Abangan,Victor Simon,Fabien Morandeau et al.
Alexa Sugpatan Abangan et al.
Infrared (IR) light is widely accepted as a non-intrusive lighting for discreet observation but relevant studies are scarce. The response of European seabass Dicentrarchus labrax (Linnaeus 1758) towards IR light was tested during laboratory...
Acclimation conditions and subsequent acute hypoxia challenges do not affect the frequency of erythrocyte nuclear segmentation in triploid brook charr Salvelinus fontinalis (Mitchill 1814) [0.03%]
不同适应条件及随后急性低氧刺激对三倍体海佻鱼Salvelinus fontinalis ( Mitchill 1814)红细胞核分段频率无影响
John D Clark,Christopher A Baker,Sarah A McGeachy et al.
John D Clark et al.
Routine observations of blood smears have repeatedly shown that triploid fish have a greater proportion of erythrocytes with nuclear segmentation (ENS) than diploids; however, there is as yet no understanding of why this is the case and whe...
