Mortality drives production dynamics of Atlantic cod through 1100 years of commercial fishing
Abstract Most edible fish species have been fished for centuries or millennia, leaving little record or understanding of their population responses prior to human impact and thus no baseline for population conservation. Here, we reconstruct the population dynamics of Atlantic cod, one of the world’s most harvested fish species, from the pristine state during the Viking era through more than 1100 years of fishing.
Temperature and body size affect movement of juvenile Atlantic cod (Gadus morhua) and saithe (Pollachius virens) at nearshore nurseries
1 INTRODUCTION Seasonal migrations are common in a wide range of taxa conferring evolutionary advantages through optimal foraging (Hopcraft et al., 2014; Leu et al., 2011), growth (Brönmark et al., 2008), and access to breeding habitats (Miller et al., 2016; Winger et al., 2019).

Major changes in fish thermal habitat diversity in Canada’s Arctic lakes due to climate change - Communications Earth & Environment
Abstract Climate warming is a major disruptor of fish community structure globally. We use large-scale geospatial analyses of 447,077 Canadian Arctic lakes to predict how climate change would impact lake thermal habitat diversity across the Arctic landscape. Increases in maximum surface temperature (+2.4–6.7 °C), ice-free period (+14–38 days), and thermal stratification presence (+4.2–18.9%) occur under all climate scenarios.

Species independence of eye lens dimensions in teleosts and elasmobranchs
Loading metrics Open Access Peer-reviewed Research Article Abstract The vertebrate eye lens grows incrementally, adding layers of elongated, tightly packed lens fiber cells at the outer margin of the lens. With subsequent growth, previously-deposited fiber cells degrade, leaving a region of fully denucleated and organelle-free cells which are responsible for the high transparency and low light scattering characteristics of the lens.
Horizontal and Vertical Migration of Anglerfish Lophius piscatorius in Relation to Hydrography in Faroese Waters
Introduction Anglerfish (genus Lophius) have an affinity for the relatively warm water masses of the mid-latitudes. The anglerfish species Lophius piscatorius in the northeast Atlantic is a boreal fish, which generally is distributed between the Straits of Gibraltar and the western Mediterranean Sea (Caruso, 1983) in the south, Icelandic waters in the west (Solmundsson et al., 2010) and the Barents Sea in the north (Thangstad et al., 2006).
Arctic freshwater fish productivity and colonization increase with climate warming
Abstract Climate warming at high latitudes has long been expected to exceed that predicted for tropical and temperate climes, but recent warming in the Arctic has exceeded even those expectations1. The geophysical consequences of this warming are reasonably well established2, but the impacts on freshwater fauna are poorly understood.
Transboundary movements, unmonitored fishing mortality, and ineffective international fisheries management pose risks for pelagic sharks in the Northwest Atlantic
Life as a shark: always on the move What is a sustainable mortality level for a discarded shark species? Sharks are fish. Although this fact should be obvious to all, it is often overlooked amidst the public and conservationist attention accorded the larger species of this taxon. Indeed, the attention given to many sharks is more in line with that given to some other, equally charismatic but phylogenetically different aquatic organisms such as whales. Whales are mammals, of course.
