The uncertainties and the data management of deep water bathymetric data obtained

, 2010
Bathymetric data are essential for safety navigations and earth scientific researches. As the international standards for bathymetric survey (IHO S 445 ed.) was revised in 2008, we had needed to evaluate qualities and uncertainties of bathymetric data ...

Hidden partnerships in the dark: Cold‐water coral–fish associations in Fiordland, New Zealand

Journal of Fish Biology, EarlyView.
Abstract The ichthyofauna of the Fiordland ecosystems of southern Aotearoa New Zealand was documented during four remotely operating vehicle (ROV) dives between 100 and 350 m depth. A total of 26 fish species were documented within two fiord basins.

Contrasting life‐history strategies of three sympatric icefish species in the northern Scotia Sea

Journal of Fish Biology, EarlyView.
Abstract Comprehending a species' life‐history strategies is crucial to inform effective conservation efforts. Commercial fishing impacts icefish (family: Channichthyidae) in the Scotia Sea, but detailed information on species‐specific life histories remains largely unknown.

Atlantic salmon (Salmo salar L.) kelt rheotaxis and position choice are influenced by flow velocity and turbulence in a regulated river

Journal of Fish Biology, EarlyView.
Abstract The migratory behaviour of Atlantic salmon kelts is poorly understood. Due to the Atlantic salmon's considerable socio‐economic and ecological importance, their precipitous population abundance declines, and the population resilience potential of salmon kelts, addressing these knowledge gaps is important.

Distribution and ecology of the four Macrourus species by‐caught in the longline fishery at South Georgia, Southern Ocean

Journal of Fish Biology, EarlyView.
Abstract Although Macrourus species are the main by‐catch across Southern Ocean longline fisheries, including around South Georgia, the lack of species‐specific data has hindered effective management and ecological understanding. Aggregation of macrourids at genus level masks critical interspecific differences in life‐history strategies and ...

Contrasting population genetic structures of congeneric coastal flounders associated with different early life histories

Journal of Fish Biology, EarlyView.
Abstract Marine fish species are likely to exhibit little genetic differentiation among populations due to their high dispersal potential during early life stages and migratory nature. However, recent studies have increasingly reported intraspecific genetic differentiation resulting from species‐specific ecological traits, environmental factors, and ...

Subtropical marine reserve as key habitats for the critically endangered sand tiger shark (Carcharias taurus) in the Southwestern Atlantic

Journal of Fish Biology, EarlyView.
Abstract This study documents the occurrence, seasonal patterns and reproductive activity of the sand tiger shark (Carcharias taurus) within a no‐take marine protected area in southeastern Brazil, using Baited Remote Underwater Video (BRUV) and diving records.
