The Abrupt and Persistent Decline in Recruitment Success in Northeast Arctic Cod: A Review of Probable Causes

Fish and Fisheries, EarlyView.
ABSTRACT Most of the previously large cod stocks in the North Atlantic are depleted to very low levels. A notable exception has been the Northeast Arctic cod inhabiting the Barents Sea. This cod stock reached a record high level around 2013, but since then has declined sharply, with older fish being fished out and few new recruits entering the stock ...

The Diversity of Fish Larvae in the Bons Sinais Estuary (Mozambique) and Its Role as a Nursery to Marine Fish Resources

Diversity, 2023
The study of assemblages of fish in their early phases in estuaries is an essential approach to understanding the functioning of these types of ecosystems and their role as nursery grounds for some marine fish species.

Diel variation in vertical distribution of an offshore ichthyoplankton community off the Oregon coast [PDF]

, 2007
We examined the diel ver-tical distribution, concentration, and community structure of ichthyoplank-ton from a single station 69 km off the central Oregon coast in the northeast Pacific Ocean. The 74 depth-stratified samples yielded 1571 fish larvae from

Efficacy of metabarcoding for identification of fish eggs evaluated with mock communities. [PDF]

, 2020
There is urgent need for effective and efficient monitoring of marine fish populations. Monitoring eggs and larval fish may be more informative than that traditional fish surveys since ichthyoplankton surveys reveal the reproductive activities of fish ...

Deciphering the complex life cycle and partial migration of an ecological engineer and critical Neotropical fishery species, Prochilodus costatus

Journal of Fish Biology, EarlyView.
Abstract Understanding complex migration patterns, including drivers of partial migration and habitat use, is challenging but essential for conservation, as it determines a species' adaptative capacity in the face of environmental change and anthropogenic threats.

Coastal aquaculture farms for the sea cucumber Apostichopus japonicus provide spawning and first-year nursery grounds for wild black rockfish, Sebastes schlegelii: A case study from the Luanhe River estuary, Bohai bay, the Bohai Sea, China

Frontiers in Marine Science, 2022
Aquaculture farms are known to attract wild organisms from nearby areas. Sea cucumber Apostichopus japonicus aquaculture farms in Bohai Bay, the Bohai Sea, China, might provide spawning and nursery grounds for wild black rockfish Sebastes schlegelii ...

Evidence of a marine larval stage in coastrange sculpin Cottus aleuticus from a small coastal stream in California, USA, based on otolith strontium isotopes

Journal of Fish Biology, EarlyView.
Abstract Cottus aleuticus (coastrange sculpin) is one of two North American facultatively amphidromous sculpins, but habitat use during its planktonic larval stage is poorly documented. We analysed strontium isotopes (88Sr and 87Sr/86Sr) in otoliths of 10 adult C. aleuticus from a small coastal California stream.

Assemblage structure of ichthyoplankton in the NE Atlantic in spring under contrasting hydrographic conditions

Scientific Reports, 2019
The ichthyoplankton assemblage in the Atlantic region off the NW Iberian peninsula (AR) and in the southern Bay of Biscay (SBB) and the response of the larval fish species distribution to the relatively rapidly changing hydrographic conditions in spring ...
