Using citizen science photographs to identify reproductive events in an oviparous elasmobranch. [PDF]

J Fish Biol
Abstract Identifying critical habitats is important for the effective management of vulnerable species. Critical habitats, such as mating or nursery grounds, support populations during key life stages and help to maximise reproductive output and population growth. In elasmobranchs, mating often happens over a defined season, suggesting sites associated

Using Stock Vulnerability to Evaluate Fishery‐Independent Survey Coverage and Inform Sampling Priorities

Fish and Fisheries, Volume 27, Issue 4, Page 912-926, July 2026.
ABSTRACT The consequences of mis‐managing vulnerable stocks (i.e., those with low productivity and high susceptibility to depletion) are high and potentially permanent. To support sustainable fisheries management, stock assessments can be improved by increasing the quantity and quality of fishery‐independent survey (i.e., survey) data.

Offspring Size Resolves a Population Growth Paradox in Rays and Skates

Fish and Fisheries, Volume 27, Issue 4, Page 927-941, July 2026.
ABSTRACT The maximum intrinsic population growth rate, rmax, is a key determinant of sustainable fishing limits and is increasingly used in risk assessments. We previously showed how the rmax of rays and skates (subclass Batoidea) scales with adult body size, temperature (and hence depth) such that smaller‐bodied species and those in warmer, shallower ...

Drivers of the spatial behaviour of the threatened thornback skate (Raja clavata)

Aquatic Living Resources, 2023
Fish movements are fundamental to their ecology and survival. Understanding the causes and consequences of the spatial behaviour of fish is of high relevance as it provides critical knowledge for conservation purposes. Skate (Rajidae) populations face an

Lack of Lumpfish (Cyclopterus lumpus) Susceptibility to the Infectious Salmon Anaemia Virus (ISAV) Using In Vivo Challenges

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT Infectious salmon anaemia virus (ISAV) can cause disease and mortality in Atlantic salmon (Salmo salar). The virus is endemic in several regions including the Atlantic coast of Canada. Lumpfish (Cyclopterus lumpus) are increasingly utilised as cleaner fish to control sea lice levels in Atlantic salmon farms.
