Journal of Anatomy, Volume 248, Issue 5, Page 784-805, May 2026.The expression of various genes involved in synapse development, stability and/or function was studied in developing mechanosensory neuromasts and electrosensory ampullary organs in sterlet sturgeon. Most were shared, including Slc17a8, Slc1a3 and Nrxn3, but Cbln18 was neuromast‐restricted and Tulp1 was ampullary organ‐restricted.

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.ABSTRACT Aquatic ecosystems have been in an alarming state of decline for decades. In particular, estuarine ecosystems have experienced long‐term declines in fish diversity due to factors such as habitat degradation, pollution and altered hydrology. Monitoring these systems is often limited by the difficulty and cost of conventional survey methods.

Semi-pelagic Longline and Trammel Net Elasmobranch Catches in Southern Portugal: Catch Composition, Catch Rates and Discards [PDF]
, 2004 In Portugal, elasmobranch landings have decreased substantially in recent years. In this work, elasmobranch catches in semi-pelagic longlines (1997 and 1998) were compared with those in trammel nets (2000) in the Algarve, southern Portugal areas.

Physiological Reports, Volume 14, Issue 8, April 2026.Abstract The aquaporin genes (aqps) are widely distributed among vertebrates. In cartilaginous fish, aqp3 and aqp10 are duplicated, whereas many species have lost aqp8. While the solute permeability of aquaglyceroporins and Aqp8 exhibits significant diversity, systematic evaluations of their activity within species are limited.

An epithelial signalling centre in sharks supports homology of tooth morphogenesis in vertebrates
eLife, 2022 Development of tooth shape is regulated by the enamel knot signalling centre, at least in mammals. Fgf signalling regulates differential proliferation between the enamel knot and adjacent dental epithelia during tooth development, leading to formation of

Juvenile Gadoid Distributions Are Driven by Patch Boundaries and Habitat Combinations
Ecology and Evolution, Volume 16, Issue 2, February 2026.This study used 757 stereo baited remote underwater video deployments across two Scottish sea lochs and adjacent bays (2021–2023) to investigate how seascape structure and species co‐occurrence shape the distributions of juvenile Atlantic cod (Gadus morhua), haddock (Melanogrammus aeglefinus), and whiting (Merlangius merlangus).

Distribution of skates and sharks in the North Sea: 112 years of change [PDF]
, 2016 How have North Sea skate and shark assemblages changed since the early 20th century when bottom trawling became widespread, whilst their environment became increasingly impacted by fishing, climate change, habitat degradation and other anthropogenic ...
