Rapid increase in abundance and distribution of invasive pink salmon (Oncorhynchus gorbuscha) within a diverse, large Barents Sea catchment

Journal of Fish Biology, EarlyView.
Abstract Pink salmon originate from the North Pacific area but were introduced into northwest Russia from the late 1950s onwards. Since 2017, the alien species has increased dramatically in abundance and rapidly invaded adjacent areas of the North Atlantic region.

The lethal concentration (LC50) of Zataria multiflora essential oil in fries of rainbow trout (Oncorhynchus mykiss)

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2011
This research was carried out to determine LC50 for Zataria multiflora essential oil in rainbow trout (Oncorhynchus mykiss) fries at 96 hours. In the process, we used the static O.E.C.D method for 180 rainbow trout fries weighing 5±1 grams in five ...

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

Journal of Fish Biology, EarlyView.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Evidence of a marine larval stage in coastrange sculpin Cottus aleuticus from a small coastal stream in California, USA, based on otolith strontium isotopes

Journal of Fish Biology, EarlyView.
Abstract Cottus aleuticus (coastrange sculpin) is one of two North American facultatively amphidromous sculpins, but habitat use during its planktonic larval stage is poorly documented. We analysed strontium isotopes (88Sr and 87Sr/86Sr) in otoliths of 10 adult C. aleuticus from a small coastal California stream.

The impact of isosmotic conditions on the metabolism and hypoxia tolerance of a reportedly oxyconforming teleost

Journal of Fish Biology, EarlyView.
Abstract Fish must manage the competing demands of ion balance and gas exchange across the gills – a physiological tension known as the osmorespiratory compromise. In dynamic estuarine environments, the osmorespiratory compromise may be exacerbated by variable salinity and periods of hypoxia that demand high respiratory work.

Histological characterisation of gonadal sex differentiation in Malabar red snapper (Lutjanus malabaricus) for aquaculture advancement

Journal of Fish Biology, EarlyView.
Abstract The Malabar red snapper (Lutjanus malabaricus) is a high‐value tropical marine species receiving growing attention for aquaculture development in Singapore and Southeast Asia. At present, seed production relies primarily on uncontrolled mass spawning in sea cages, a practice that lacks consistency, biosecurity and control of genetic ...

Historical case study of a transfer experiment that demonstrated the importance of the estuarine ecosystem for the survival of Chinook salmon (Oncorhynchus tshawytscha) at the Campbell River estuary, British Columbia, Canada

Journal of Fish Biology, EarlyView.
Abstract Estuary dependence to the survival of Chinook salmon was investigated at the Campbell River estuary, British Columbia, Canada. Replicate batches of marked smolts were transferred from a hatchery and released in 1983, 1984 and 1985 at four ecosystems, two that ensured estuarine experience (river, estuary) and two seawards of the estuary ...
