An investigation into the diet of elephant fish (Callorhinchus milii) in the waters of Aotearoa/New Zealand

Journal of Fish Biology, EarlyView.
Abstract Chondrichthyans (sharks, rays and chimaeras) are increasingly understood to be an important part of ocean ecosystems, but their ecological role is unclear. Callorhinchus milii (elephant fish) is a chimaera species endemic to Aotearoa/New Zealand and southern Australian waters.

Marine migration influences mercury accumulation in anadromous Arctic char (Salvelinus alpinus)

Journal of Fish Biology, EarlyView.
Abstract Mercury (Hg) is a globally distributed toxic metal present in northern natural environments that biomagnifies in food webs and bioaccumulates in apex predator fish, such as Arctic char (Salvelinus alpinus)—an iteroparous species with a circumpolar distribution. Arctic char exhibit a variety of life history types, with the migrating, anadromous

Insights into diet and niche separation in the context of prey availability between two sympatric whiprays in a tropical intertidal estuary

Journal of Fish Biology, EarlyView.
Abstract Increasing evidence supports associations between various elasmobranch species and estuarine habitats, particularly during early life stages. However, with substantial knowledge gaps surrounding spatial habitat use and trophic ecology of estuary‐associated species in Australia, we cannot reliably assess the functional importance of these areas

Cryptobenthic reef fishes may not be safe from invasive lionfish (Pterois spp. Oken, 1817)

Journal of Fish Biology, EarlyView.
Abstract Lionfish (Pterois spp.) are hypothesized to negatively influence cryptobenthic reef fish assemblages through predation. We evaluated these potential effects on Caribbean reefs in Costa Rica and tropical reefs in Brazil. Brazil provided a reference condition for cryptobenthic assemblages prior to lionfish invasion, while the Costa Rica sites ...

Age, growth and sexual dimorphism of the monkeyface prickleback (Cebidichthys violaceus)

Journal of Fish Biology, EarlyView.
Abstract Accurate estimates of age, growth and maturation are fundamental to fisheries assessment, conservation and the development of emerging aquaculture species. However, life‐history parameters can vary within species and may be influenced by factors such as sexual dimorphism, which is often poorly quantified in non‐commercial or understudied ...
