The Anatomical Record, Volume 309, Issue 4, Page 826-852, April 2026.Bioimaging of the sense organs and brain of fishes and reptiles. Left panel: 3D reconstruction of the head and brain of the deep‐sea viperfish Chauliodus sloani following diceCT. Right panel: A 3D reconstruction of a 70‐day‐old embryo head of the bearded dragon Pogona vitticeps following diceCT, showing the position of the segmented brain within the ...

Investigation of \u3cem\u3ede novo\u3c/em\u3e cholesterol synthetic capacity in the gonads of goldfish (\u3cem\u3eCarassius auratus\u3c/em\u3e) exposed to the phytosterol beta-sitosterol [PDF]
, 2006 Total and intra-mitochondrial gonadal cholesterol concentrations are decreased in fish exposed to the phytoestrogen beta-sitosterol (beta-sit). The present study examined the potential for beta-sit to disrupt de novo cholesterol synthesis in the gonads ...

Journal of Comparative Neurology, Volume 534, Issue 4, April 2026.The absolute and relative volume of major sensory and integrative brain regions of the southern bluefin tuna Thunnus maccoyii are examined using magnetic resonance imaging (MRI). A dominant cerebellum projects into the midbrain ventricular space, while the optic tectum represents a smaller proportion of total brain volume than previously estimated ...

Spontaneous melanotic lesions in axillary seabream, Pagellus acarne (Risso) [PDF]
, 2013 In this paper, we describe spontaneous melanotic lesions in the skin of axillary seabream, Pagellus acarne (Risso) from a defined area of the Portuguese Coast, located in Cabo da Roca and Foz do Arelho.

An Inactive Thyroid Gland in Carassius auratus [PDF]
Nature, 1956 Carassius auratus has been subjected to prolonged artificial selection which has established several unusual features. Among these is the inactivity of the thyroid gland. This gland consists of follicles scattered along the anterior region of the ventral aorta; the follicles are typically inactive, with squamous epithelium and abundant colloid.

Ethology, Volume 132, Issue 4, Page 295-304, April 2026.Environmental contamination with the synthetic estrogen 17α‐ethinyl estradiol (EE2) is widespread in coastal ecosystems, yet behavioural effects in marine fishes remain poorly understood. We exposed southern crested weedfish (Cristiceps australis) to low and high EE2 concentrations for 14 days and assessed boldness and anxiety using a refuge‐use assay.

Journal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.Abstract A 54‐day feeding trial was conducted to investigate the effects of dietary protein levels on growth performance, digestive capacity, plasma biochemical indexes, and gene expression in Hefang crucian carp (Carassius auratus). Six experimental diets were prepared with protein levels of 21.7%, 24.0%, 29.4%, 34.0%, 38.0%, and 43.2%, respectively ...

Journal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.Abstract The NLRP3 inflammasome is essential for innate immunity against pathogens, yet its function in amphibians remains poorly understood. Here, we identified and cloned two novel isoforms of NLRP3 from the American bullfrog (Aquarana catesbeiana), designated AcNLRP3 X1 and AcNLRP3 X2, with open reading frames of 2397 bp (798 aa) and 2874 bp (957 aa)

Ecology and Evolution, Volume 16, Issue 3, March 2026.PhyloRef processes complete mitochondrial genomes with optional multi‐gene concatenation to flag three categories of phylogenetic anomalies based on tree topology and annotates ambiguous sequences with “similar_to=” labels. The workflow successfully curated 7600+ chondrichthyan and actinopterygian sequences from NCBI, identifying and removing 410 ...

Contaminant‐Driven Modulation of Environmental DNA and RNA in Aquatic Systems
Environmental DNA, Volume 8, Issue 2, March/April 2026.This study investigates how lead (Pb) and polyethylene (PE) microbreads influence eDNA and eRNA signals in salmon and eels. While Pb exposure does not interfere with eNA signals, PE microbeads increase eRNA production and slow molecular degradation, prolonging the detection window of eNA in aquatic ecosystems.
