Assessment of Spawning and Nursery Areas in the River Meuse

open access: yesWater Science and Technology, 1994
In commission of Rijkswaterstaat Directorate Limburg, a desk study was carried out by the OVB to assess whether fish species in the river Meuse are restricted in their abundance and distribution by the lack of appropriate spawning habitat. The area studied comprises the Dutch part of the river between Eijsden and Hedel, including old river arms and ...

Spawning areas and spawning period of the North-east Arctic haddock [HELP 25} [PDF]

open access: yes, 1989
Spawning of North-East Artic haddock occurs on the Norwegian continental slope. The location of the spawning grounds is, however, diffuse. This is mainly due to difficulties in identifying haddock eggs. In this work this problem is solved by using the biochemical genetical approach of electrophoresis.

Evidence of Genetic Segregation among Meagre (Argyrosomus regius) Atlantic Spawning Areas

open access: yesJournal of Marine Science and Engineering, 2022
The meagre Argyrosomus regius, one of the largest sciaenidae in the world, is a valuable resource for fisheries and aquaculture. Despite its socioeconomic relevance, knowledge about population dynamics and wild stocks is still scarce, and conservation ...

Using fishers’ knowledge to determine the spatial extent of deep-water spawning of capelin (Mallotus villosus) in Newfoundland, Canada

open access: yesFrontiers in Marine Science, 2023
IntroductionOn the Newfoundland-Labrador Shelf, Canada, capelin (Mallotus villosus) is a key forage fish that migrates annually from offshore to spawn within coastal embayments.

Ecology and evolution of migration in the freshwater eels of the genus Anguilla Schrank, 1798

open access: yesHeliyon, 2020
Scientists have long sought to uncover the secrets of the migration of anguillid eels, genus Anguilla. As catadromous fishes, anguillid eels spend most of their lives in freshwater until they return to their spawning grounds in the tropics, although part

Seasonal approach to forecast the suitability of spawning habitats of a temperate small pelagic fish under a high-emission climate change scenario

open access: yesFrontiers in Marine Science, 2022
Spawning habitats of cold-water, European small pelagic fishes have shifted poleward in the last three decades coincident with gradual ocean warming. We predicted present-day, season-specific habitat suitability for spawning by European sardine Sardina ...

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

open access: yesPLoS 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 ...

Incorporating egg-transporting pathways into conservation plans of spawning areas: An example of small yellow croaker (Larimichthys polyactis) in the East China Sea zone

open access: yesFrontiers in Marine Science, 2022
Backward-in-time Lagrangian model can identify potential spawning areas by reconstructing egg drift trajectories, contributing to accurately designing potential priority conservation plans for spawning areas.

A possible new spawning area for Atlantic bluefin tuna (Thunnus thynnus): the first histologic evidence of reproductive activity in the southern Gulf of Mexico [PDF]

open access: yesPeerJ, 2019
The number of studies of reproductive biology for Atlantic bluefin tuna carried out in the Gulf of Mexico is significantly lower than those undertaken in the Mediterranean Sea.
