Early life history of the Korean seahorse, Hippocampus haema: Evidence for direct settlement and ontogenetic shifts in snout morphology

Journal of Fish Biology, EarlyView.
Abstract Early life‐history traits of seahorses are closely linked to juvenile survival, dispersal potential and the onset of substrate attachment; however, detailed stage‐resolved descriptions remain limited for many Hippocampus species. This study examined reproductive behaviour and early ontogenetic development of the Korean seahorse, Hippocampus ...

Integrated multitissue analysis reveals distinct oxidative stress responses during recovery from cold shock in the Amazonian fish Colossoma macropomum

Journal of Fish Biology, EarlyView.
Abstract Tambaqui (Colossoma macropomum) is a tropical fish widely cultivated in South America. The increasing demand for this species has heightened interest in its cultivation in subtropical regions with greater thermal variability, where cold shock may induce oxidative stress. This study evaluated the effects of cold shock and subsequent recovery on

The case of Artemia spp. in nanoecotoxicology

Marine Environmental Research, 2014
Artemia spp. is one of the most widespread saltwater organism suitable for ecotoxicity testing, but no internationally standardised methods exist. Several endpoints can be considered with Artemia spp. including short-term (24-48 h) and long-term (14 days) mortality, cysts and nauplii hatchability, biomass productivity, biomarkers' expression/inhibition

Continuous darkness is associated with improved growth performance during a high‐temperature period and sex‐specific modulation of early gonadal development in juvenile yellowtail (Seriola quinqueradiata)

Journal of Fish Biology, EarlyView.
Abstract Selective breeding of yellowtail (Seriola quinqueradiata) is expanding in Japan, increasing the demand for practical reproductive control tools in commercial aquaculture to reduce genetic risks from escapees. Slowing early gonadal development through environmental manipulation may support future sterilization strategies, particularly when ...

Evaluating astigmatid mites as supplemental food for Macrolophus pygmaeus: contrasting responses between commercial and wild populations. [PDF]

Pest Manag Sci
Astigmatid mites provide low‐cost supplemental food for Macrolophus pygmaeus, supporting survival and development, with population‐specific responses and Acarus siro and Carpoglyphus lactis as the most promising alternatives. Abstract BACKGROUND Early establishment of Macrolophus pygmaeus in crops depends on the availability of supplemental food ...

Spawning behaviour between endemic delta smelt (Hypomesus transpacificus) and non‐native Wakasagi (H. nipponensis) in the San Francisco estuary

Journal of Fish Biology, EarlyView.
Abstract In the San Francisco Estuary, non‐native Wakasagi Hypomesus nipponensis hybridize with endemic and endangered Delta Smelt H. transpacificus, and all wild‐caught hybrids have a maternal Wakasagi parent. However, the mechanisms that facilitate or impede hybridization and explain sex‐biased hybrid asymmetry between these two species remain ...

Axial muscle‐fibre orientations in larval zebrafish

Journal of Anatomy, Volume 246, Issue 4, Page 517-533, April 2025.
In 4 days post‐fertilization zebrafish larvae, the fast axial muscle fibres follow helical trajectories that taper towards the tail. Adjacent muscle fibres form substantial angles relative to each other to accommodate this pattern. Using a novel semi‐automatic method, we quantified 3D fibre angles over the whole muscle volume.

Cryopreservation of decapsulated Artemia sp. embryos

, 1996
The decapsulated Artemia sp. embryos at their blastula stage were successfully cryopreserved in liquid nitrogen with various concentrations of glycerol, DMSO, glucose and sucrose as single cryoprotectants. Higher cryoprotectant concentrations were better
