BIOCHEMICAL STUDIES ON SALMONIDAE II

Bulletin of the Agricultural Chemical Society of Japan, 1929
1) The influence of the sun-light on the eggs, larvae and fry of Oncorhynchus masou (Brevoort) are studied. 2) The intensity of the sun-light may be effected already upon their chemical compositions in the fry through the oval and larval stages. The fish fed in the lighter place (in the open air out of the hatchery), as compared with the darker place ...

A Synthesis of Factors Related to Trends in Abundance and Demography of Alaska Chinook Salmon (Oncorhynchus tshawytscha, Salmonidae): Implications for Research, Management, and Policy

Fish and Fisheries, EarlyView.
ABSTRACT Across Alaska, there have been synchronous declines in the abundance, mean age, and size of Chinook salmon (Oncorhynchus tshawytscha, Salmonidae), a species with immense social and ecological importance. The decline of Chinook salmon, and regulations addressing declines, have drastically impacted people who rely on Alaska's fisheries.

Is it possible to contribute to the recovery of European grayling (Thymallus thymallus, Salmonidae) populations by stocking cultured brood fish in the pre‐spawning period?

Journal of Fish Biology, EarlyView.
Abstract European grayling populations have declined significantly in their central range, prompting numerous stocking programs with reared fish that did not bring desirable population prosperity. This study evaluated the effectiveness of stocking long‐reared grayling brood fish before their spawning period.

Concise history of the acclimatisation of the Salmonidae in Tasmania [PDF]

Papers and proceedings of the Royal Society of Tasmania, 1888
The idea of acclimatising the English salmon (Salmo salar) in Tasmanian waters was entertained by some of the colonists at a very early period in our history. In the year 1844, as recorded in Vol. 1, p. 28 1, of the " Proceedings of the Royal Society of Tasmania," the late Captain Frederick Chalmers, of Brighton, in Tasmania, applied to Dr.

Histology and Ultrastructure of the Nephron and Kidney Interstitial Cells in the Atlantic Salmon (Salmo salar Linnaeus 1758) at Different Stages of Life Cycle

Biology, 2023
This article presents data on the mesonephros histology and ultrastructure in the Atlantic salmon from the Baltic Sea and Barents Sea populations, with an emphasis on comparisons between the following ontogenetic stages: parr, smolting, adult life at sea,

Climate tracking by freshwater fishes suggests that fish diversity in temperate lakes may be increasingly threatened by climate warming

Diversity and Distributions, Volume 29, Issue 2, Page 300-315, February 2023., 2023
Abstract Aim Many freshwater fishes are migrating poleward to more thermally suitable habitats in response to warming climates. In this study, we aimed to identify which freshwater fishes are most sensitive to climatic changes and asked: (i) how fast are lakes warming? (ii) how fast are fishes moving?

Distinct latitudinal community patterns of Arctic marine vertebrates along the East Greenlandic coast detected by environmental DNA

Diversity and Distributions, Volume 29, Issue 2, Page 316-334, February 2023., 2023
Abstract Aim Greenland is one of the places on Earth where the effects of climate change are most evident. The retreat of sea ice has made East Greenland more accessible for longer periods during the year. East Greenland fjords have been notoriously difficult to study due to their remoteness, dense sea ice conditions and lack of infrastructure.

Vertical ambush corridors: Intriguing multi‐mechanism ecological structures embedded in the kinetic fluid architectures of ocean living resource production systems

Fish and Fisheries, Volume 24, Issue 1, Page 3-20, January 2023., 2023
Abstract The concept of a ‘vertical ambush corridor’ is herein introduced to marine ecosystem science. In the open ocean, adequate physical cover from which to launch an unanticipated ambush attack is generally lacking. An available alternative is for a predator to channel its attack vertically upward from below, rendering an unlighted approaching ...

Air movement sound production by alewife, white sucker, and four salmonid fishes suggests the phenomenon is widespread among freshwater fishes. [PDF]

PLoS ONE, 2018
We sought to describe sounds of some of the common fishes suspected of producing unidentified air movement sounds in soundscape surveys of freshwater habitats in the New England region of North America.

Season and environment modulate aquatic invertebrates’ responses to trout and indigenous fishes in three South African mountain streams

Frontiers in Environmental Science, 2022
Introduced organisms are seen as one of the greatest threats to resource sustainability worldwide, and aquatic macroinvertebrates are regarded as good indicators of the health of water resources.
