Modified fin morphology in mackerel icefish (Champsocephalus gunnari) may indicate nesting behaviour

open access: yesJournal of Fish Biology, EarlyView.
Abstract Monitoring reproductive traits in Southern Ocean species is challenging. Males in some channichthyids thicken the epithelium along their anal fins to aid nest construction. This study presents initial evidence that the only commercially harvested channichthyid, mackerel icefish (Champsocephalus gunnari), exhibits modifications to their anal ...

Estimating Fishing Exploitation Rates to Simulate Global Catches and Biomass Changes of Pelagic and Demersal Fish

open access: yesEarth's Future
Robust projections of future trends in global fish biomass, production and catches are needed for informed fisheries policy in a changing climate. Trust in future projections, however, relies on establishing that models can accurately simulate past ...

Temperature, but not acidification, influences the growth and lipid profile of juvenile sand whiting, Sillago ciliata (Cuvier 1829)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Seafood provides an essential source of macro‐ and micronutrients for coastal communities worldwide. Climate change is a key threat to seafood security, altering the sizes, abundances, distributions, physiology and ecological interactions of fisheries species, and increasingly, there is evidence of impacts to seafood nutritional quality.

Top‐down pressure on a coastal ecosystem by harbor seals

open access: yesEcosphere, 2019
Historic hunting has led to severe reductions of many marine mammal species across the globe. After hunting ceased, some populations have recovered to pre‐exploitation levels and may have regained their prominent position as top predator in marine ...

Size‐, sex‐ and site‐dependent morphological variation in the stone flounder (Kareius bicoloratus) from Korean coastal waters

open access: yesJournal of Fish Biology, EarlyView.
Abstract Kareius bicoloratus is a commercially important flatfish in Korean coastal fisheries and an ecologically relevant benthic species in nearshore ecosystems. To evaluate how multiple biological and environmental factors jointly shape flatfish morphology, we analysed 81 morphometric indices and two‐dimensional geometric morphometrics (GMM) in wild

Take my breath away: Defining the oxygen saturation threshold for fish cortisol stress response

open access: yesJournal of Fish Biology, EarlyView.
Abstract Human activities are affecting the number, size and severity of hypoxic zones in aquatic ecosystems. As oxygen is one of the most important abiotic factors affecting fish biology, exposure to low levels of dissolved oxygen may lead to a reduction in fitness.
