Sodium thiosulfate treatment rescues hyperglycaemia‐induced pronephros damage in zebrafish by upregulating nitric oxide signalling

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Sodium thiosulfate (STS) rescues the pronephros phenotype of pdx1 morphants through compensatory upregulation of nitric oxide (NO) metabolism. Zebrafish larvae injected with a control morpholino show the typical pronephros structure at 48 h post‐fertilization (hpf) with and without STS treatment.

The Feeding Ecology of Invasive Pink Salmon Juveniles in Northern Norwegian Rivers and Their Role as Prey to Native Salmonids

open access: yesEcology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Increasing numbers of invasive Pacific pink salmon (Oncorhynchus gorbuscha) are spawning in northern Norwegian rivers, leading to large numbers of juveniles migrating to coastal waters. This raises concerns about food competition with native salmonids in rivers, although details about the timing and intensity of pink salmon feeding and the ...

Reproductive Biology and Hormonal Induction Protocols for Labeo dero (Hamilton 1822): A Foundational Framework for Conservation Aquaculture in Bangladesh

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
A reproductive biology study of Labeo dero reveals a July breeding peak with female GSI reaching 14.9 %. Induced breeding trials establish optimal doses of 6 mg kg−1 (♀) and 3 mg kg−1 (♂) carp pituitary extract (94.7 % spawning) and 0.6 mL kg−1 (♀) and 0.3 mL kg−1 (♂) Ovuhom (82.3 % spawning).

Gonadal Histology and Spawning Season of Otolithoides pama in the Thanlwin River Estuary

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT The spawning season of Otolithoides pama in the Thanlwin estuary was estimated through gonadosomatic index (GSI) and histological analyses of gonadal development. A total of 290 specimens (240 females and 50 males) were collected monthly from 5 sites—Ahlat, Kyauk Tan, Daye, Nyaung Pin Seik and Tarana—between January and December 2024.

Estimation and rapid identification of later stages during embryonic development of the oviparous lizard Sceloporus aeneus (Squamata: Phrynosomatidae)

open access: yesThe Anatomical Record, Volume 309, Issue 6, Page 1583-1598, June 2026.
Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.
