Induction of out‐of‐season spawning in an intensively reared walleye ( Sander vitreus ) broodstock

Aquaculture, Fish and Fisheries
The commercial viability of walleye (Sander vitreus) as an aquaculture species requires that walleye gametes are available year‐round so that multiple cohorts of walleye can be brought to market throughout the year. This study aimed to apply photothermal

Thermal conditions and age structure determine the spawning regularities and condition of Baltic herring (Clupea harengus membras) in the NE of the Baltic Sea [PDF]

PeerJ, 2019
Baltic herring (Clupea harengus membras) is a total spawner with a group-synchronous ovarian organization. Age polymodality in total spawners is considered an important factor in assuring that a strong population is sustainable under an intensive ...

Analysis of reproductive traits reveals complex population dynamics on a small geographical scale in Atlantic herring

Frontiers in Marine Science, 2023
Atlantic herring (Clupea harengus) has a complex population structure and displays a variety of reproductive strategies. Differences in reproductive strategies among herring populations are linked to their time of spawning, as well as to their ...

Tracing the Food Web of Changing Arctic Ocean: Trophic Status of Highly Abundant Fish, Gasterosteus aculeatus (L.), in the White Sea Recovered Using Stomach Content and Stable Isotope Analyses

Diversity, 2022
Studies of dietary preferences of migratory species are of great importance as these species connect food webs of habitats across the migration route and thus represent trophic relationships between the spatially disjointed communities. Here we described

Spawning site selection and contingent behavior in Common Snook, Centropomus undecimalis. [PDF]

PLoS ONE, 2014
Reproductive behavior affects spatial population structure and our ability to manage for sustainability in marine and diadromous fishes. In this study, we used fishery independent capture-based sampling to evaluate where Common Snook occurred in Tampa ...

Spawning characteristics of blue sprat (Spratelloides gracilis) in the waters of Penghu, central Taiwan Strait

Frontiers in Marine Science, 2023
Blue sprat (Spratelloides gracilis) is an economically valuable species that inhabits the central Taiwan Strait. However, despite the implementation of a local management scheme involving a closed season between 1 May and 1 June, the annual catch has ...

Reproductive strategy of Delta Smelt Hypomesus transpacificus and impacts of drought on reproductive performance.

PLoS ONE, 2022
Understanding reproductive biology and performance of fish is essential to formulate effective conservation and management programs. Here, we studied reproductive strategies of female Delta Smelt Hypomesus transpacificus, an endangered fish species in ...

Wild and farmed burbot Lota lota: differences in energy consumption and behavior during the spawning season

Aquaculture Environment Interactions, 2021
Farmed fish released in a native environment can display different spawning behaviour compared to their wild conspecifics. In our study, farmed and wild burbot, a species recently introduced for aquacultural production, were equipped with electromyogram (
