The feeding ecology of some zooplankters that are important prey items of larval fish [PDF]

open access: yes, 1984
Diets of 76 species of fish larvae from most oceans of the world were inventoried on the basis of information in 40 published studies. Although certaln geographlc, size- and taxon-specific patterns were apparent, certain zooplankton taxa appeared in the ...

Genome Expansion of ZPB1(a) and ZPC1(a) in Basal Species or Liver Expression of ZPB1a and ZPC1aa in Advanced Species, Two Different Strategies to Ensure Sufficient ZP Synthesis in Teleosts

open access: yesIntegrative Zoology, EarlyView.
We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

Complete mitochondrial genome and the phylogenetic position of the tigertooth croaker Otolithes ruber (Perciformes: Sciaenidae)

open access: yesMitochondrial DNA. Part B. Resources, 2017
In this study, the complete mitogenome of the tigertooth croaker Otolithes ruber was first determined. This mitogenome is 16,589 bp in length, and consists of 37 genes with the typical gene order and direction of transcription in vertebrates. The overall

Exposure to the Oestrogenic Pollutant 17α‐Ethinyl Estradiol (EE2) Does Not Alter the Behaviour of a Coastal Marine Fish, Cristiceps australis

open access: yesEthology, EarlyView.
Environmental contamination with the synthetic estrogen 17α‐ethinyl estradiol (EE2) is widespread in coastal ecosystems, yet behavioural effects in marine fishes remain poorly understood. We exposed southern crested weedfish (Cristiceps australis) to low and high EE2 concentrations for 14 days and assessed boldness and anxiety using a refuge‐use assay.

Natural spawning of four Epinephelus species in the laboratory [PDF]

open access: yes, 1996
Natural spawnings of four Epinephelus species reared in the laboratory were observed from 1987 to 1992. These species are: E. summana, E. caeruleopunctatus, E. macrospilus and E. fuscoguttatus.

Assessing the population structure of Plagioscion squamosissimus (Teleostei, Perciformes, Sciaenidae) from the São Francisco River, Bahia, Brazil, using body morphology and otolith shape signatures

open access: yesJournal of Fish Biology, EarlyView.
Abstract The south American silver croaker, Plagioscion squamosissimus, holds significant importance for the artisanal fisheries in the sub‐middle and lower courses of the São Francisco River, located in northeastern Brazil. To investigate the population structure of this species along its longitudinal profile, a total of 150 individuals (50 fish per ...

Period of the day drives distinctions in the taxonomic and functional structures of reef fish assemblages

open access: yesJournal of Fish Biology, EarlyView.
Abstract Circadian processes are key drivers of animal behaviour, influencing patterns of activity, resource partitioning and competition avoidance. Studies evaluating circadian changes on the structure of marine assemblages are lacking, especially for reef fish.

European sea bass (Dicentrarchus labrax) skin and scale transcriptomes [PDF]

open access: yes, 2017
Fish skin and their appendages, the mineralized scales, are important organs for protection and homeostasis, but little is known about their specific transcript or protein repertoire.

20 Years Later: Updated Stock Assessment of Snappers in Northeast Brazil Using an Integrated Stock Assessment Framework

open access: yesFisheries Management and Ecology, Volume 33, Issue 1, Page 69-87, February 2026.
ABSTRACT We updated the stock status of Lutjanus analis, Lutjanus jocu, Lutjanus synagris, and Ocyurus chrysurus harvested along the Brazilian northeastern coast. Stock boundaries were defined according to the Marine Ecoregion classifications at a finer scale, to reflect the population structure of each species.

Ichthyological ecoregions of Argentina [PDF]

open access: yes, 2002
The Argentine Republic is situated in the southernmost portion of the American continent, occupying over 2,785,600 km2 not including the Antarctic territory. The country ranges from subtropical areas (21º46’S) to subantarctic regions (55º03’S), extending
