Ichthyoplankton and plastic waste drift in a river in the Amazon Basin, Brazil

Frontiers in Environmental Science, 2023
Egg and larvae drift is a key mechanism for early fish stages to colonize nursery and growth areas and provides insights into ichthyofauna spawning times and spawning locations—crucial information for understanding fish biology.

Seasonal, lunar and tidal control of ichthyoplankton dynamics at the interface between a temperate estuary and adjacent coastal waters (western Portugal)

Scientia Marina, 2012
Influence of season, lunar-tide cycle and tide on ichthyoplankton at the interface between Mondego estuary and the adjacent coast and on up-estuary transport was evaluated.

A Preliminary Ichthyoplankton Survey of the Tsitsikamma National Park [PDF]

South African Journal of Zoology, 1994
An ichthyoplankton survey using bongo nets was conducted within the Tsitsikamma National Park over an 18-month period between January 1991 and July 1992. Four sampling stations along the coast were chosen, approximately 5 km apart. At each station four samples were taken along a transect perpendicular to the coast, between 0,35 km and 3,8 km offshore ...

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

J Fish Biol
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.

Stable Isotope–Enabled Particle Drift Models Predict Where High‐Resolution Isotope Analyses Can Discriminate Among Larval Trajectories in Atlantic Mackerel

Fisheries Oceanography, Volume 35, Issue 5, Page 760-776, September 2026.
ABSTRACT Marine fish commonly move across distinct habitats throughout their lifetimes, particularly during larval stages, when they are particularly difficult to track. Such transitions are necessary as environmental demands and predation pressures change dramatically with increases in body size.

Strong spatial partitioning of mesozooplankton in a dynamic frontal zone shapes trophic transfer efficiency

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Frontal zones are often areas of increased biological productivity and have hydrographic gradients on short spatial scales. The small scale of gradients poses a challenge in identifying differences in zooplankton community structure and trophic transfer efficiency through the pelagic food web.

Biodiversity of North Sea Pelagic Cephalopod Early Life Phases

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT Cephalopods are increasing in biomass and abundance in the North Sea. In addition to their amplified importance for the ecosystem, they have also become a relevant resource for fisheries and landings are rising. Besides a growing knowledge about cephalopod biology, many gaps exist about the early life phases (ELP) of cephalopods. For the first

Description of the Early Development of Hoplias intermedius (Günther, 1864) (Characiformes: Erythrinidae)

Journal of Morphology, Volume 287, Issue 7, July 2026.
This study provides the first description of the early development of Hoplias intermedius (Characiformes: Erythrinidae), from the embryonic to the juvenile stage. The morphological, meristic, and morphometric characterization contributes to understanding the ontogeny and developmental transitions of Neotropical fishes, supporting taxonomy, conservation,

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 ...
