Impact of light pollution on fishes: Mechanisms and ecological consequences

Journal of Fish Biology, EarlyView.
Abstract The increasing prevalence of artificial light at night (ALAN) is of growing ecological concern. By altering natural light regimes, ALAN affects the behaviour, physiology and life‐history of organisms. While research has largely focused on terrestrial ecosystems, aquatic ecosystems are increasingly exposed.

The Demographic Benefits of Diel Vertical Migration by Zooplankton [PDF]

, 1990
Three types of diel vertical migration behavior were expressed within a fjord population of the calanoid copepod Pseudocalanus newmani: (1) reverse migration (nocturnal descent), (2) normal migration (nocturnal ascent), and (3) no detectable migration ...

Ontogenetic and spatial variation in the trophic ecology of the shortfin mako shark (Isurus oxyrinchus) in temperate eastern Australia

Journal of Fish Biology, EarlyView.
Abstract The shortfin mako (Isurus oxyrinchus) is a fast‐swimming pelagic shark of global ecological and socioeconomic importance, yet it is relatively understudied in temperate eastern Australian waters. This study investigated the trophic ecology of mako sharks using stable isotope analysis (SIA) of nitrogen (δ15N), carbon (δ13C) and sulphur (δ34S ...

Global length–weight relationships of deep‐pelagic fishes: Coverage, biases and variability

Journal of Fish Biology, EarlyView.
Abstract Length–weight relationships (LWRs) are morphometric tools that allow body mass to be estimated from fish length, providing input for fisheries, ecological and biodiversity studies. For deep‐pelagic fishes, however, LWR data remain fragmented and unavailable for most species.

Winter feeding during the spawning migration of capelin north of Iceland

Journal of Fish Biology, EarlyView.
Abstract Winter feeding during the spawning migration of capelin is often assumed to be minimal, because energy is allocated to reproduction. However, January–February surveys north of Iceland in 2018 and 2019 showed that prey occurred in 64% and 62% of 423 stomachs examined, respectively. Copepods (Calanus spp.) and euphausiids dominated the diet, and

Diel release timing is a critical determinant of reef fish survival in Post‐larval Capture, Culture, and Release

Restoration Ecology, EarlyView.
Abstract Introduction Predation is a dominant force shaping survival of coral reef fishes. Synchronous, nocturnal settlement during low‐light, new moon periods may have developed as an adaptive response to intense predation during settlement. Post‐larval Capture, Culture, and Release (PCCR), where juvenile fishes are released directly to the reef ...

Understanding Biogeographic Patterns in Sepiolidae (Cephalopoda)

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 10, October 2026.
ABSTRACT The biogeography of the bobtail squid family Sepiolidae is reviewed. Species of the Sepiolinae subfamily are only found in coastal waters of the ‘Old World’, with a high degree of diversification in the Mediterranean Sea and the Coral Triangle in the Indo‐Pacific region.

Diel vertical migration of copepods in a Brazilian lake: a mechanism for decreasing risk of Chaoborus predation?

Brazilian Journal of Biology
A comparison between two studies on diel vertical migration of two cyclopoid copepod species, in Lake Monte Alegre, undertaken in 1985/86 and 1999, revealed a change in their migratory behavior.

Diel Vertical Migration of Chaetognaths in the Tsushima Current Area of the Japan Sea

, 1998
Vertical distribution and diel migration of chaetognaths were studied in Toyama Bay and at Yamato Tai, areas affected by the Tsushima Current in the Japan Sea. Contrary to the common pattern, immature individuals of the cold water species Sagitta elegans
